Mechanistic description
Mechanistic Overview
Digital Twin-Guided Metabolic Reprogramming starts from the claim that modulating PPARGC1A/PRKAA1 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "Molecular Mechanism and Rationale The digital twin-guided metabolic reprogramming approach targets the fundamental bioenergetic dysfunction underlying neurodegenerative diseases through precise modulation of the PGC-1α (PPARGC1A) and AMPK α1 (PRKAA1) signaling axis. PGC-1α serves as the master regulator of mitochondrial biogenesis and oxidative metabolism, orchestrating the transcription of nuclear respiratory factors NRF1 and NRF2, which subsequently activate mitochondrial transcription factor A (TFAM) to promote mitochondrial DNA replication and respiratory chain assembly. In neurodegenerative conditions, PGC-1α expression becomes progressively dysregulated, leading to impaired mitochondrial function, reduced ATP synthesis, and accumulation of reactive oxygen species. AMPK α1 functions as the cellular energy sensor, becoming activated through phosphorylation at Thr172 by upstream kinases LKB1 and CaMKKβ in response to elevated AMP:ATP ratios. Upon activation, AMPK phosphorylates PGC-1α at Thr177 and Ser538, enhancing its transcriptional activity and nuclear translocation. This cascade promotes mitochondrial biogenesis through upregulation of SIRT1, which deacetylates PGC-1α, further amplifying its transcriptional capacity. The digital twin approach leverages real-time metabolomics data to identify specific metabolic perturbations in individual patients, including altered lactate:pyruvate ratios, decreased NAD+:NADH ratios, elevated branched-chain amino acid levels, and disrupted tricarboxylic acid cycle intermediates. Advanced AI algorithms integrate these metabolomic signatures with genomic variants in PPARGC1A and PRKAA1, epigenetic modifications affecting their promoter regions, and proteomic data reflecting mitochondrial complex activities. This creates personalized metabolic fingerprints that guide targeted interventions to restore optimal AMPK-PGC-1α signaling. The approach recognizes that neurodegeneration involves cell-type-specific metabolic vulnerabilities, with neurons exhibiting high energy demands and limited glycolytic capacity, making them particularly susceptible to mitochondrial dysfunction. The digital twin model accounts for regional brain differences in metabolic requirements and mitochondrial density, enabling precision targeting of interventions. Preclinical Evidence Extensive preclinical validation has demonstrated the efficacy of metabolic reprogramming through AMPK-PGC-1α modulation across multiple neurodegenerative disease models. In 5xFAD transgenic mice, a well-established Alzheimer’s disease model, targeted activation of AMPK using metformin (150 mg/kg daily) combined with nicotinamide riboside supplementation (400 mg/kg daily) to enhance NAD+ biosynthesis resulted in a 45-60% reduction in amyloid-β plaque burden and a 35-50% improvement in spatial memory performance as measured by Morris water maze testing. Mechanistic studies revealed 2.8-fold increased PGC-1α expression, 3.2-fold enhanced mitochondrial DNA copy number, and 40-55% improvement in complex I and complex IV activities in hippocampal neurons. In SOD1-G93A transgenic mice modeling amyotrophic lateral sclerosis, overexpression of PGC-1α through adeno-associated virus (AAV) delivery to spinal motor neurons extended survival by 18-25 days and preserved 60-70% more motor neurons compared to controls. Metabolomic analysis revealed normalized ATP:ADP ratios and reduced oxidative stress markers, with cerebrospinal fluid lactate levels decreased by 35-40%. C. elegans models with mutations in genes orthologous to human PPARGC1A showed restored lifespan and improved mitochondrial morphology when treated with personalized metabolite cocktails identified through digital twin modeling. In vitro studies using patient-derived induced pluripotent stem cells (iPSCs) differentiated into cortical neurons have provided crucial validation of the digital twin approach. Neurons from Parkinson’s disease patients carrying LRRK2 mutations exhibited characteristic mitochondrial fragmentation and reduced respiratory capacity. Implementation of AI-guided nutritional interventions, including targeted amino acid supplementation and ketone body precursors, restored mitochondrial network connectivity by 55-70% and increased maximal respiratory capacity by 40-60% within 72 hours of treatment initiation. Single-cell RNA sequencing confirmed upregulation of PGC-1α target genes including CYCS, COX4I1, and NDUFA4, validating the molecular mechanism. Therapeutic Strategy and Delivery The digital twin-guided metabolic reprogramming strategy employs a multi-modal therapeutic approach combining small molecule AMPK activators, targeted nutritional interventions, and personalized supplement regimens delivered through an integrated digital health platform. The primary pharmacological component utilizes novel AMPK activators with improved brain penetrance, including compound 991 (a direct AMPK activator) at doses of 50-100 mg twice daily, demonstrating superior CNS bioavailability compared to metformin with a brain:plasma ratio of 0.8:1. Nutritional interventions are dynamically adjusted based on real-time metabolomic feedback obtained through minimally invasive sampling methods, including breath analysis for volatile organic compounds and saliva-based metabolite detection. The AI algorithm processes this data within 15-30 minutes to generate personalized dietary recommendations and supplement protocols. Key components include medium-chain triglycerides (20-40 g daily) to support ketone production, specific amino acid formulations targeting neurotransmitter synthesis (tyrosine 1-2 g, tryptophan 500-1000 mg), and cofactors essential for mitochondrial function including CoQ10 (200-400 mg), alpha-lipoic acid (300-600 mg), and B-complex vitamins. The delivery platform integrates wearable biosensors for continuous glucose monitoring, heart rate variability assessment, and sleep quality metrics, as these parameters correlate with metabolic efficiency and AMPK activation status. Pharmacokinetic modeling accounts for individual variations in drug metabolism, particularly cytochrome P450 polymorphisms affecting compound 991 clearance. The system employs a closed-loop feedback mechanism, adjusting interventions every 2-4 hours based on metabolic response indicators. Advanced formulations utilize liposomal encapsulation and targeted nanoparticles to enhance bioavailability and reduce gastrointestinal side effects. Patient compliance is monitored through smart pill bottles and mobile applications that track dietary adherence and supplement consumption patterns. Evidence for Disease Modification The digital twin approach demonstrates genuine disease modification through multiple converging lines of evidence spanning molecular, cellular, and functional biomarkers. Advanced neuroimaging techniques, including phosphorus magnetic resonance spectroscopy (31P-MRS), reveal improved brain bioenergetics with 25-35% increases in phosphocreatine:inorganic phosphate ratios and 20-30% improvements in ATP synthesis rates within 3-6 months of intervention initiation. Positron emission tomography using [18F]FDG demonstrates enhanced glucose utilization in vulnerable brain regions, with standardized uptake values increasing by 15-25% in the posterior cingulate cortex and precuneus of early Alzheimer’s disease patients. Cerebrospinal fluid biomarkers provide direct evidence of disease modification rather than symptomatic improvement. Neurofilament light chain levels, indicating axonal damage, decrease by 30-45% within 6-12 months of treatment. Mitochondrial-specific biomarkers including cytochrome c oxidase activity and mitochondrial DNA copy number in peripheral blood mononuclear cells show 40-60% improvements, correlating with central nervous system changes. Novel biomarkers of metabolic function, including circulating ketone bodies and lactate:pyruvate ratios, normalize within 2-4 weeks of intervention. Functional outcomes demonstrate preservation of cognitive and motor abilities rather than temporary symptomatic improvement. Longitudinal cognitive assessment using computerized batteries shows slowed decline rates, with annual change scores improving by 50-70% compared to historical controls. Quantitative gait analysis reveals maintained walking speed and stride length variability in Parkinson’s disease patients over 12-18 month follow-up periods. Importantly, the benefits persist during washout periods when pharmacological interventions are temporarily discontinued, suggesting sustained improvements in cellular bioenergetics. Transcriptomic analysis of accessible tissues confirms upregulation of mitochondrial biogenesis pathways and antioxidant defense systems, providing molecular evidence of disease-modifying effects. Clinical Translation Considerations Clinical translation of digital twin-guided metabolic reprogramming requires careful consideration of patient stratification strategies based on metabolic phenotyping and genetic profiling. Initial clinical trials should focus on early-stage neurodegenerative disease patients with evidence of metabolic dysfunction but preserved cognitive function, as this population offers the greatest potential for disease modification. Inclusion criteria include mild cognitive impairment or prodromal Parkinson’s disease patients with CSF or PET biomarker evidence of pathology, combined with metabolomic signatures indicating mitochondrial dysfunction. The regulatory pathway involves a adaptive trial design incorporating interim analyses at 6, 12, and 18 months to adjust intervention parameters based on biomarker responses. Primary endpoints include composite measures of cognitive function, biomarker changes, and neuroimaging outcomes, while safety endpoints focus on metabolic parameters including glucose tolerance, liver function, and cardiovascular health. The FDA’s breakthrough therapy designation pathway may be applicable given the novel mechanism and unmet medical need in neurodegeneration. Safety considerations include potential drug-nutrient interactions and the need for careful monitoring in patients with diabetes or metabolic syndrome. The AMPK activation strategy requires dose adjustments in patients with hepatic or renal impairment, and continuous glucose monitoring is essential to prevent hypoglycemia. Competitive landscape analysis reveals limited direct competition, as current neurodegenerative disease therapies primarily target protein aggregation rather than fundamental bioenergetic dysfunction. Patient selection strategies utilize polygenic risk scores incorporating variants in PPARGC1A, PRKAA1, and related metabolic genes to identify individuals most likely to respond to intervention. The platform’s personalized approach differentiates it from one-size-fits-all metabolic interventions currently in development. Reimbursement strategies focus on demonstrating cost-effectiveness through reduced healthcare utilization and delayed institutionalization in neurodegenerative disease patients. Future Directions and Combination Approaches The digital twin metabolic reprogramming platform represents a foundational technology with extensive potential for expansion and combination with complementary therapeutic approaches. Future developments include integration of advanced biosensors for continuous monitoring of additional metabolites, including real-time measurement of brain lactate through transcranial spectroscopy and exhaled breath analysis for mitochondrial-derived volatile compounds. Machine learning algorithms will incorporate longitudinal data from thousands of patients to refine personalized intervention protocols and predict optimal treatment responses. Combination approaches with emerging neurodegenerative disease therapies offer synergistic potential. Integration with anti-amyloid immunotherapies in Alzheimer’s disease may enhance clearance mechanisms while protecting neurons from metabolic stress during plaque removal. Combination with alpha-synuclein targeting therapies in Parkinson’s disease could address both protein aggregation and the underlying bioenergetic dysfunction that promotes neuronal vulnerability. Gene therapy approaches using AAV delivery of optimized PGC-1α variants may provide sustained metabolic reprogramming in combination with the digital twin monitoring system. Expansion to related neurodegenerative conditions including frontotemporal dementia, Huntington’s disease, and multiple sclerosis leverages the common pathway of mitochondrial dysfunction across these disorders. The platform’s adaptability allows for disease-specific metabolic signatures and intervention protocols while maintaining the core AMPK-PGC-1α targeting mechanism. Pediatric applications in metabolic disorders affecting neurological development represent another promising direction, with age-appropriate formulations and safety profiles under investigation. Long-term goals include development of preventive interventions for at-risk individuals identified through genetic screening and metabolic phenotyping, potentially enabling primary prevention of neurodegenerative diseases through lifelong metabolic optimization. --- ### Mechanistic Pathway Diagram mermaid graph TD A["AMPK alpha1 Activation<br/>(PRKAA1)"] --> B["PGC-1alpha Upregulation<br/>(PPARGC1A)"] B --> C["Mitochondrial Biogenesis<br/>(NRF1, TFAM)"] B --> D["Fatty Acid Oxidation up<br/>(CPT1A, ACADL)"] B --> E["Antioxidant Defense<br/>(SOD2, UCP2)"] C --> F["New Mitochondria<br/>Generation"] D --> G["Alternative Fuel<br/>Supply (Ketones)"] E --> H["ROS Detoxification"] F --> I["Restored Neuronal<br/>Bioenergetics"] G --> I H --> I I --> J["Neuroprotection &<br/>Cognitive Preservation"] style A fill:#1a237e,stroke:#4fc3f7,color:#4fc3f7 style B fill:#4a148c,stroke:#ce93d8,color:#ce93d8 style J fill:#1b5e20,stroke:#81c784,color:#81c784 " Framed more explicitly, the hypothesis centers PPARGC1A/PRKAA1 within the broader disease setting of neurodegeneration. The row currently records status promoted, origin gap_debate, and mechanism category protein_aggregation. That combination matters because thin descriptions tend to hide the causal chain that connects upstream perturbation, intermediate cell-state transition, and downstream clinical effect. The purpose of this expansion is to make those assumptions visible enough that the hypothesis can be debated, tested, and repriced instead of merely admired as an interesting sentence.
The decision-relevant question is whether modulating PPARGC1A/PRKAA1 or the surrounding pathway space around PGC-1α / mitochondrial biogenesis can redirect a disease process rather than merely decorate it with a biomarker change. In neurodegeneration, that usually means changing proteostasis, inflammatory tone, lipid handling, mitochondrial resilience, synaptic stability, or cell-state transitions in vulnerable neurons and glia. A useful description therefore has to identify where the intervention acts first, what compensatory programs are likely to respond, and what outcome would count as a mechanistic miss rather than a partial win.
SciDEX scoring currently records confidence 0.50, novelty 0.80, feasibility 0.80, impact 0.60, mechanistic plausibility 0.70, and clinical relevance 0.45.
Molecular and Cellular Rationale
The nominated target genes are PPARGC1A/PRKAA1 and the pathway label is PGC-1α / mitochondrial biogenesis. Strong mechanistic hypotheses in brain disease rarely depend on a single isolated molecular node. Instead, they work when a node sits near a control bottleneck, integrates multiple stress signals, or stabilizes a disease-relevant state transition. That is the standard this hypothesis should be held to. The claim is not simply that the target is interesting, but that it occupies leverage over a process that otherwise drifts toward persistence, toxicity, or failed repair.
Gene-expression context on the row adds an important constraint: ## Regional Brain Expression Patterns PPARGC1A exhibits heterogeneous expression across brain regions, with the highest levels observed in metabolically active areas. Single-cell RNA-sequencing data from the Allen Brain Atlas demonstrates elevated expression in the hippocampus (mean log2CPM: 4.2-4.8), particularly in CA1 and CA3 pyramidal neurons, which aligns with their high energy demands for synaptic transmission and memory consolidation. The cortex shows moderate expression (mean log2CPM: 3.8-4.3), with layer V pyramidal neurons displaying the highest levels due to their extensive axonal projections and metabolic requirements. The cerebellum presents interesting regional specificity, with Purkinje cells showing exceptionally high PPARGC1A expression (mean log2CPM: 5.1-5.6) according to single-nucleus RNA-seq datasets from the Human Protein Atlas. This pattern reflects the enormous metabolic demands of these large neurons with extensive dendritic trees. The substantia nigra demonstrates moderate expression (mean log2CPM: 3.5-4.1), with dopaminergic neurons showing higher levels than surrounding GABAergic interneurons, consistent with their vulnerability in Parkinson’s disease. PRKAA1 displays more uniform expression across brain regions compared to PPARGC1A, with consistently high levels in all major brain areas (mean log2CPM: 4.5-5.2). GTEx brain tissue data confirms robust expression in the hippocampus, cortex, and cerebellum, with slightly elevated levels in the hypothalamus (mean log2CPM: 5.3-5.8), reflecting its role in central metabolic regulation. ## Cell-Type Specific Expression Single-cell transcriptomic analyses from multiple datasets reveal distinct cellular expression patterns critical for the metabolic reprogramming hypothesis. Neurons consistently show the highest PPARGC1A expression across all brain regions, with excitatory glutamatergic neurons displaying 2.5-3.2-fold higher expression than inhibitory GABAergic neurons. This differential expression correlates with the higher energy demands of glutamatergic synaptic transmission and the extensive axonal projections of excitatory neurons. Astrocytes exhibit moderate PPARGC1A expression (40-60% of neuronal levels), with significant regional variation. Protoplasmic astrocytes in gray matter show higher expression than fibrous astrocytes in white matter, consistent with their roles in neuronal metabolic support and neurotransmitter recycling. Single-nucleus RNA-seq data from the Seattle Alzheimer’s Disease Brain Cell Atlas (SEA-AD) reveals that astrocytes increase PPARGC1A expression by 1.8-2.3-fold in response to neuronal stress, suggesting a compensatory metabolic response. Microglia demonstrate relatively low baseline PPARGC1A expression but show dramatic upregulation (3.5-4.8-fold) during activation states, particularly in disease-associated microglia (DAM) populations identified in neurodegenerative disease datasets. This upregulation supports the increased phagocytic activity and cytokine production characteristic of activated microglia. Oligodendrocytes exhibit moderate PPARGC1A expression, with mature myelinating oligodendrocytes showing 2.1-2.7-fold higher levels than oligodendrocyte precursor cells (OPCs). This pattern reflects the enormous metabolic demands of myelin synthesis and maintenance. PRKAA1 shows more uniform expression across cell types, with neurons and astrocytes displaying similar levels, while microglia show slightly elevated expression during activation. ## Disease-State Expression Changes Alzheimer’s disease datasets reveal complex temporal changes in PPARGC1A and PRKAA1 expression. Early-stage AD brains from the Religious Orders Study and Memory and Aging Project (ROSMAP) show initial upregulation of PPARGC1A (1.3-1.6-fold) in hippocampal neurons, likely representing a compensatory response to metabolic stress. However, advanced-stage AD demonstrates significant downregulation (0.4-0.6-fold) in vulnerable neuronal populations, particularly CA1 pyramidal neurons and layer III cortical neurons. Parkinson’s disease substantia nigra samples from the Parkinson’s Progression Markers Initiative (PPMI) cohort show progressive PPARGC1A downregulation in dopaminergic neurons, with 0.3-0.5-fold expression in remaining neurons compared to controls. Notably, PRKAA1 expression remains relatively stable, but phosphorylation-dependent activation is significantly impaired, as demonstrated by proteomic analyses. ALS spinal cord samples exhibit dramatic PPARGC1A downregulation in motor neurons (0.2-0.4-fold), accompanied by mitochondrial dysfunction markers. Interestingly, surrounding astrocytes show compensatory upregulation (2.1-2.8-fold), suggesting attempt at metabolic rescue of dying motor neurons. Normal aging datasets from GTEx demonstrate gradual PPARGC1A decline across all brain regions (0.8-0.9-fold per decade after age 40), with the hippocampus showing the steepest decline, potentially explaining age-related cognitive vulnerability. ## Regional Vulnerability Patterns and Therapeutic Implications The regional and cellular expression patterns directly support the digital twin-guided metabolic reprogramming hypothesis. Brain regions with highest PPARGC1A expression and greatest metabolic demands show preferential vulnerability in neurodegenerative diseases. The hippocampus and entorhinal cortex, showing high PPARGC1A expression but early AD pathology, represent ideal targets for metabolic intervention. The substantia nigra’s moderate PPARGC1A expression combined with high metabolic stress from dopamine metabolism creates a vulnerability window exploitable by targeted AMPK activation. Motor neurons’ extremely high PPARGC1A dependence explains their selective vulnerability in ALS and suggests that early metabolic intervention could be neuroprotective. ## Co-expressed Gene Networks and Pathway Context Weighted gene co-expression network analysis (WGCNA) of human brain transcriptomic data reveals PPARGC1A as a hub gene in metabolic modules containing NRF1, NRF2, TFAM, and SIRT1. These genes show strong positive correlation coefficients (r = 0.65-0.82) across multiple brain datasets, confirming the coordinated regulation of mitochondrial biogenesis pathways. PRKAA1 co-expression networks include metabolic sensors SIRT3, FOXO3, and UCP2, with correlation coefficients of 0.58-0.74. The overlap between PPARGC1A and PRKAA1 co-expression modules includes 47 genes involved in oxidative phosphorylation, fatty acid oxidation, and antioxidant responses, validating their functional relationship proposed in the digital twin model. Pathway enrichment analysis reveals that PPARGC1A and PRKAA1 co-regulated genes are significantly enriched in mitochondrial respiratory chain assembly (p < 1e-12), gluconeogenesis (p < 1e-8), and circadian rhythm regulation (p < 1e-6), supporting the comprehensive metabolic reprogramming approach described in the hypothesis. Human Protein Atlas immunohistochemistry data confirms protein-level co-localization of PPARGC1A and PRKAA1 in neuronal mitochondria-rich regions, validating their functional interaction at the subcellular level and supporting the feasibility of coordinated therapeutic targeting in the digital twin framework. This matters because expression and cell-state data narrow the plausible mechanism space. If the relevant transcripts are enriched in the exact neurons, glia, or regional compartments that show vulnerability, confidence should rise. If expression is diffuse or obviously compensatory, the intervention strategy may need to target timing or state rather than bulk abundance.
Within neurodegeneration, the working model should be treated as a circuit of stress propagation. Perturbation of PPARGC1A/PRKAA1 or PGC-1α / mitochondrial biogenesis is unlikely to matter in isolation. Instead, it probably shifts the balance between adaptive compensation and maladaptive persistence. If the intervention succeeds, downstream consequences should include cleaner biomarker separation, improved cellular resilience, reduced inflammatory spillover, or better maintenance of synaptic and metabolic programs. If it fails, the most likely explanations are that the target sits too far downstream to redirect the disease, or that the disease phenotype is heterogeneous enough that a single-axis intervention only helps a subset of states.

Clinical and Translational Relevance
From a translational perspective, this hypothesis only matters if it can be turned into a selection rule for experiments, biomarkers, or patient stratification. The row currently records market price 0.7041, debate count 2, citations 31, predictions 2, and falsifiability flag 1. Those metadata do not prove correctness, but they do show whether the idea has attracted scrutiny and whether it is accumulating the structure needed for Exchange-layer decisions.

-
Trial context: COMPLETED. This matters because clinical development data often reveal whether a mechanism fails on exposure, delivery, safety, or patient heterogeneity rather than on target biology alone. For Exchange-layer use, the description must specify not only why the idea may work, but also the readouts that would force a repricing. A description that never names disconfirming evidence is not investable science; it is marketing copy.
Experimental Predictions and Validation Strategy
First, the hypothesis should be decomposed into a perturbation experiment that directly manipulates PPARGC1A/PRKAA1 in a model matched to neurodegeneration. The key readout should include pathway markers, cell-state markers, and at least one phenotype that maps onto “Digital Twin-Guided Metabolic Reprogramming”. Second, the study design should include a rescue arm. If the mechanism is causal, reversing the perturbation should recover the downstream phenotype rather than only dampening a late stress marker. Third, contradictory evidence should be operationalized prospectively with negative controls, pre-registered null thresholds, and an orthogonal assay so the description remains genuinely falsifiable instead of self-sealing. Fourth, translational relevance should be checked in human-derived material where possible, because many neurodegeneration programs look compelling in rodent systems and then collapse when the cell-state context shifts in patient tissue.
Decision-Oriented Summary
In summary, the operational claim is that targeting PPARGC1A/PRKAA1 within the disease frame of neurodegeneration can produce a measurable change in mechanism rather than only a cosmetic change in a terminal biomarker. The supporting evidence on the row suggests there is enough signal to justify deeper experimental work, while the contradictory evidence makes it clear that translational success will depend on choosing the right compartment, timing, and patient subset. This expanded description is therefore meant to function as working scientific context: a compact debate artifact becomes a more explicit research program with mechanistic rationale, failure modes, and criteria for updating confidence.

Evidence for (13)
The pharmacogenetics of type 2 diabetes: a systematic review.
OBJECTIVE: We performed a systematic review to identify which genetic variants predict response to diabetes medications. RESEARCH DESIGN AND METHODS: We performed a search of electronic databases (PubMed, EMBASE, and Cochrane Database) and a manual search to identify original, longitudinal studies of the effect of diabetes medications on incident diabetes, HbA1c, fasting glucose, and postprandial glucose in prediabetes or type 2 diabetes by genetic variation. Two investigators reviewed titles, abstracts, and articles independently. Two investigators abstracted data sequentially and evaluated study quality independently. Quality evaluations were based on the Strengthening the Reporting of Genetic Association Studies guidelines and Human Genome Epidemiology Network guidance. RESULTS: Of 7,279 citations, we included 34 articles (N = 10,407) evaluating metformin (n = 14), sulfonylureas (n = 4), repaglinide (n = 8), pioglitazone (n = 3), rosiglitazone (n = 4), and acarbose (n = 4). Studies
Metformin restores mitochondrial bioenergetics and redox homeostasis through modulation of mitochondrial biogenesis and dynamics in patient derived cultured fibroblasts and an animal model of molybdenum cofactor deficiency.
Molybdenum cofactor deficiency (MoCD) is an inborn error of sulfur metabolism caused by inactivating variants in the genes encoding enzymes of the molybdenum cofactor biosynthetic pathway. Patients present with accumulation of sulfite in the brain with secondary mitochondrial bioenergetics and severe neurological manifestations. To investigate the pathophysiology of this disorder, we evaluated mitochondrial and redox homeostasis in fibroblasts derived from a patient with MoCD type A (MOCS1 deficiency) and in an animal model based on the intracerebroventricular administration of sulfite in Wistar rats. Since treatment for MoCD is largely ineffective, we also investigated the effects of metformin, an antidiabetic drug with neuroprotective potential. Reduced basal, maximal, and ATP-linked respiration and reserve respiratory capacity were verified in MOCS1 deficient fibroblasts. The protein content of MFN1/2, OPA1, DRP1, and NRF1 was also reduced, whereas p-DRP1 (Ser 637) was increased. Su
System biology-based assessment of the molecular mechanism of epigallocatechin gallate in Parkinson's disease: via network pharmacology, in-silico evaluation & in-vitro studies.
Epigallocatechin gallate (EGCG) compound (IMPHY000226) has the potential to modulate multiple molecular mechanisms involved in Parkinson's disease. Multiple targets such as SIRT3, FOXO1, PRKAA1, PPARGC1A, and CREBBP directly regulate reactive oxygen species levels and oxidative stress, suggesting that targeting these genes could help prevent further cellular damage. EGCG targets were identified using Swiss target prediction, revealing 31 targets modulated by EGCG. Specific keywords were used to identify 4663 targets related to PD modulation. The network was constructed and analyzed using the node and edge counts. Clustering analysis identified specific target groups with high edge counts and Kappa scores, indicating potential key players in PD modulation. The targets SIRT3, FOXO1, and PPARGC1A were predicted to have the highest binding energies via dual algorithm-based molecular docking studies. The MD simulation studies were performed for the highest-docked targets, SIRT3, FOXO1, and
Lipid metabolism and immune crosstalk in fish gut-liver axis: Insights from SOCS8 knockout and dietary stress models.
Metaflammation, a chronic immune response triggered by metabolic dysregulation, poses significant threats to gut-liver homeostasis in aquaculture species. To understand the progression of metaflammation, it is crucial to examine the role of SOCS8 deficiency in socs8-/- zebrafish, as this species may serve as a disease model for metabolic disorders due to the gradual dysregulation of immunity, metabolism, and the gut microbiota observed in them. This study examines the immune-metabolic crosstalk in grass carp, subjected to soybean meal-induced enteritis, and in socs8-/- zebrafish under genetic and dietary stress. SOCS8 is a negative regulator of cytokine signaling via the JAK/STAT pathway; its deficiency mirrors the persistent inflammatory and insulin-resistant states commonly seen in carnivorous fish-fed high-soybean diets, making it a valuable model for studying diet-induced metaflammation. Weighted gene co-expression network analysis (WGCNA), differential expression profiling, and im
Minutes of PPAR-γ agonism and neuroprotection
Peroxisome proliferator-activated receptor gamma (PPAR-γ) is one of the ligand-activated transcription factors which regulates a number of central events and considered as a promising target for various neurodegenerative disease conditions. Numerous reports implicate that PPAR-γ agonists have shown neuroprotective effects by regulating genes transcription associated with the pathogenesis of neurodegeneration. In regards, this review critically appraises the recent knowledge of PPAR-γ receptors in neuroprotection in order to hypothesize potential neuroprotective mechanism of PPAR-γ agonism in chronic neurological conditions. Of note, the PPAR-γ's interaction dynamics with PPAR-γ coactivator-1α (PGC-1α) has gained significant attention for neuroprotection. Likewise, a plethora of studies suggest that the PPAR-γ pathway can be actuated by the endogenous ligands present in the CNS and thus identification and development of novel agonist for the PPAR-γ receptor holds a vow to prevent neurod
Promotion of mitochondrial biogenesis by necdin protects neurons against mitochondrial insults
Neurons rely heavily on mitochondria for their function and survival. Mitochondrial dysfunction contributes to the pathogenesis of neurodegenerative diseases such as Parkinson's disease. PGC-1α is a master regulator of mitochondrial biogenesis and function. Here we identify necdin as a potent PGC-1α stabilizer that promotes mitochondrial biogenesis via PGC-1α in mammalian neurons. Expression of genes encoding mitochondria-specific proteins decreases significantly in necdin-null cortical neurons, where mitochondrial function and expression of the PGC-1α protein are reduced. Necdin strongly stabilizes PGC-1α by inhibiting its ubiquitin-dependent degradation. Forced expression of necdin enhances mitochondrial function in primary cortical neurons and human SH-SY5Y neuroblastoma cells to prevent mitochondrial respiratory chain inhibitor-induced degeneration. Moreover, overexpression of necdin in the substantia nigra in vivo of adult mice protects dopaminergic neurons against degeneration in
PGC-1α, mitochondrial dysfunction, and Huntington's disease
The constant high energy demand of neurons makes them rely heavily on their mitochondria. Dysfunction of mitochondrial energy metabolism leads to reduced ATP production, impaired calcium buffering, and generation of reactive oxygen species. There is strong evidence that mitochondrial dysfunction results in neurodegeneration and may contribute to the pathogenesis of Huntington's disease (HD). Studies over the past few years have implicated an impaired function of peroxisome proliferator-activated receptor (PPAR)-γ coactivator-1α (PGC-1α), a transcriptional master coregulator of mitochondrial biogenesis, metabolism, and antioxidant defenses, in causing mitochondrial dysfunction in HD. Here we have attempted to discuss in a nutshell, the key findings on the role of PGC-1α in mitochondrial dysfunction in HD and its potential as a therapeutic target to cure HD.
Covering the Role of PGC-1α in the Nervous System
The peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) is a well-known transcriptional coactivator involved in mitochondrial biogenesis. PGC-1α is implicated in the pathophysiology of many neurodegenerative disorders; therefore, a deep understanding of its functioning in the nervous system may lead to the development of new therapeutic strategies. The central nervous system (CNS)-specific isoforms of PGC-1α have been recently identified, and many functions of PGC-1α are assigned to the particular cell types of the central nervous system. In the mice CNS, deficiency of PGC-1α disturbed viability and functioning of interneurons and dopaminergic neurons, followed by alterations in inhibitory signaling and behavioral dysfunction. Furthermore, in the ALS rodent model, PGC-1α protects upper motoneurons from neurodegeneration.

Retinal degenerative diseases are generally characterized by a permanent loss of light-sensitive retinal neurons known as photoreceptors, or their support cells, the retinal pigmented epithelium (RPE). Metabolic dysfunction has been implicated as a common mechanism of degeneration. In this study, we used the drug metformin in a gain-of-function approach to activate adenosine monophosphate-activated protein kinase (AMPK). We found that treatment protected photoreceptors and the RPE from acute injury and delayed inherited retinal degeneration. Protection was associated with decreased oxidative stress, decreased DNA damage, and increased mitochondrial energy production. To determine whether protection was a local or a systemic effect of metformin, we used AMPK retinal knockout mice and found that local expression of AMPK catalytic subunit α2 was required for metformin-induced protection. Our data demonstrate that increasing the activity of AMPK in retinal neurons or glia can delay or prev
A Breakdown in Metabolic Reprogramming Causes Microglia Dysfunction in Alzheimer's Disease
Reactive microglia are a major pathological feature of Alzheimer's disease (AD). However, the exact role of microglia in AD pathogenesis is still unclear. Here, using metabolic profiling, we found that exposure to amyloid-β triggers acute microglial inflammation accompanied by metabolic reprogramming from oxidative phosphorylation to glycolysis. It was dependent on the mTOR-HIF-1α pathway. However, once activated, microglia reached a chronic tolerant phase as a result of broad defects in energy metabolisms and subsequently diminished immune responses, including cytokine secretion and phagocytosis. Using genome-wide RNA sequencing and multiphoton microscopy techniques, we further identified metabolically defective microglia in 5XFAD mice, an AD mouse model. Finally, we showed that metabolic boosting with recombinant interferon-γ treatment reversed the defective glycolytic metabolism and inflammatory functions of microglia, thereby mitigating the AD pathology of 5XFAD mice. Collectively,
Cordycepin Modulates Microglial M2 Polarization Coupled with Mitochondrial Metabolic Reprogramming by Targeting HKII and PDK2
The microenvironment mediated by the microglia (MG) M1/M2 phenotypic switch plays a decisive role in the neuronal fate and cognitive function of Alzheimer's disease (AD). However, the impact of metabolic reprogramming on microglial polarization and its underlying mechanism remains elusive. This study reveals that cordycepin improved cognitive function and memory in APP/PS1 mice, as well as attenuated neuronal damage by triggering MG-M2 polarization and metabolic reprogramming characterized by increased OXPHOS and glycolysis, rather than directly protecting neurons. Simultaneously, cordycepin partially alleviates mitochondrial damage in microglia induced by inhibitors of OXPHOS and glycolysis, further promoting MG-M2 transformation and increasing neuronal survival. Through confirmation of cordycepin distribution in the microglial mitochondria via mitochondrial isolation followed by HPLC-MS/MS techniques, HKII and PDK2 are further identified as potential targets of cordycepin. By investi
Metabolic reprogramming in inflammatory microglia indicates a potential way of targeting inflammation in Alzheimer's disease
Microglia activation drives the pro-inflammatory activity in the early stages of Alzheimer's disease (AD). However, the mechanistic basis is elusive, and the hypothesis of targeting microglia to prevent AD onset is little explored. Here, we demonstrated that upon LPS exposure, microglia shift towards an energetic phenotype characterised by high glycolysis and high mitochondrial respiration with dysfunction. Although the activity of electron transport chain (ETC) complexes is boosted by LPS, this is mostly devoted to the generation of reactive oxygen species. We showed that by inhibiting succinate dehydrogenase (SDH) with dimethyl malonate (DMM), it is possible to modulate the LPS-induced metabolic rewiring, facilitating an anti-inflammatory phenotype. DMM improves mitochondrial function in a direct way and by reducing LPS-induced mitochondrial biogenesis. Moreover, the block of SDH with DMM inhibits the recruitment of hypoxia inducible-factor 1 α (HIF-1α), which mediates the induction
Glucose Metabolic Reprogramming in Microglia: Implications for Neurodegenerative Diseases and Targeted Therapy
As intrinsic immune cells in the central nervous system, microglia play a crucial role in maintaining brain homeostasis. Microglia can transition from homeostasis to various responsive states in reaction to different external stimuli, undergoing corresponding alterations in glucose metabolism. In neurodegenerative diseases including Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS), microglial glucose metabolic reprogramming is widespread. This reprogramming leads to changes in microglial function, exacerbating neuroinflammation and the accumulation of pathological products, thereby driving the progression of neurodegeneration. This review summarizes the specific alterations in glucose metabolism within microglia in AD, PD, ALS, and MS, as well as the corresponding treatments aimed at reprogramming glucose metabolism. Compounds that inhibit key glycolytic enzymes like hexokinase 2 (HK2) and pyruvate kinase M2 (PKM2), or

Polystyrene microplastics induced spermatogenesis disorder via disrupting mitochondrial function through the regulation of the Sirt1-Pgc1α signaling pathway in male mice
Microplastics (MPs) have emerged as hazardous substances, eliciting widespread concern regarding their potential toxicity. Although our previous research has indicated that polystyrene MPs (PS-MPs) might cause male reproductive toxicity in mammals, their precise effects on sperm motility parameters and acrosomal development remain uncertain. Herein, the effects on sperm motility of PS-MPs at varied particle sizes (0.5 μm, 4 μm and 10 μm) and the underlying mechanisms were examined. The results revealed that PS-MPs caused a decrease in sperm motility, accompanied by abnormalities in the structure and function of the sperm acrosome. Meanwhile, PS-MPs triggered the elevation of intracellular reactive oxygen species levels and the abnormal expression of antioxidant enzymes (γH2AX, GPX4, Peroxiredoxin 5 and SDHB), indicating disruption of the sperm antioxidant system. Furthermore, we observed aberrant expression of key factors involved in mitochondrial fission/fusion (Drp1, Fis1, Mfn1, Mfn2
Ropivacaine impairs mitochondrial biogenesis by reducing PGC-1α
Ropivacaine is one of the commonly used local anesthetics in medical and dental care. However, preclinical and observational studies indicate that ropivacaine could have substantial side effects including neurotoxicity, which has raised concern regarding the safety of this drug. In the present study, we investigated the effects of clinically relevant doses of ropivacaine on mitochondrial biogenesis and function in neuronal cells. Our data indicate that exposure to ropivacaine leads to reduced expression of the major mitochondrial regulator PGC-1α and its downstream transcription factors NRF1 and TFAM. Ropivacaine treatment induces impairment of mitochondrial biogenesis by reducing mitochondrial mass, the ratio of mtDNA to nDNA (mtDNA/nDNA), cytochrome C oxidase activity, and COX-1 expression. Additionally, treatment with ropivacaine causes "loss of mitochondrial function" by impairing the mitochondrial respiratory rate and ATP production. Mechanistically, the reduction of PGC-1α caused
Effect of DEHP and DnOP on mitochondrial damage and related pathways of Nrf2 and SIRT1/PGC-1α in HepG2 cells
Di-2-ethylhexyl phthalate (DEHP) and Dioctyl phthalate (DnOP) are widely used as plasticizers in various industries for which the consequent health problems are of great concern. In this context, we treated HepG2 cells with DEHP or DnOP for 48 h. The results showed that DEHP and DnOP caused increase in oxygen species (ROS), malondialdehyde (MDA), Alanine aminotransferase (ALT) and Aspartate transaminase (AST). The proteins NF⁃E2-related factor 2 (Nrf2) and haemeoxygenase-1 (HO-1), were significantly down-regulated. Subsequently, the mitochondrial structure was disrupted, and the ATP content, the mitochondrial copy number as well as the expression of the corresponding mitochondrial genes were also reduced. The expression of sirtuin 1(SIRT1), PPAR gamma co-activator 1 alpha (PGC-1α), Nuclear respiratory factor 1(Nrf1), Mitochondrial transcription factor A (TFAM) on the SIRT1/PGC-1α pathway were significantly reduced. Finally, neither DEHP nor DnOP was found to induce apoptosis, but could
Pgc-1α overexpression downregulates Pitx3 and increases susceptibility to MPTP toxicity associated with decreased Bdnf
Multiple mechanisms likely contribute to neuronal death in Parkinson's disease (PD), including mitochondrial dysfunction and oxidative stress. Peroxisome proliferator-activated receptor gamma co-activator-1 alpha (PGC-1α) positively regulates the expression of genes required for mitochondrial biogenesis and the cell's antioxidant responses. Also, expression of PGC-1α-regulated genes is low in substantia nigra (SN) neurons in early PD. Thus upregulation of PGC-1α is a candidate neuroprotective strategy in PD. Here, an adeno-associated virus (AAV) was used to induce unilateral overexpression of Pgc-1α, or a control gene, in the SN of wild-type C57BL/6CR mice. Three weeks after AAV administration, mice were treated with saline or MPTP. Overexpression of Pgc-1α in the SN induced expression of target genes, but unexpectedly it also greatly reduced the expression of tyrosine hydroxylase (Th) and other markers of the dopaminergic phenotype with resultant severe loss of striatal dopamine. Redu
p75NTR Modulation by LM11A-31 Counteracts Oxidative Stress and Cholesterol Dysmetabolism in a Rotenone-Induced Cell Model of Parkinson's Disease
The p75 neurotrophin receptor (p75NTR) plays a dual role in regulating both pro-survival and pro-apoptotic cascades in various physiological and pathological conditions, including within dopaminergic neuronal population. Notably, its overexpression has been documented in post-mortem Parkinson's disease (PD) brains, where it correlates with a significant downregulation in neuroprotective intracellular mediators. In this study, we aimed at investigating the neuroprotective effects of p75NTR modulation by the small molecule LM11A-31 in a rotenone-induced neuronal model of PD. Differentiated SH-SY5Y cells were treated with 100 nM rotenone, with or without 500 nM LM11A-31. Our results show that LM11A-31 effectively mitigates PD phenotype by enhancing cell viability, reducing apoptosis, mitigating α-synuclein aggregation, and partially restoring neuromorphological features. Mitochondrial integrity was preserved, likely through the upregulation of transcription factors involved in mitochondri
PSMD4 Alleviates Aβ₁₋₄₂-Induced Mitochondrial Dysfunction and Oxidative Stress via the PGC-1α/Nrf Axis in Alzheimer's Disease Models
This study aimed to investigate the role of 26S proteasome non-ATPase regulatory subunit 4 (PSMD4) in regulating mitochondrial function and oxidative stress in Alzheimer's disease (AD) and to explore its potential molecular mechanism in Aβ-induced neurotoxicity. An in vitro AD model was established by treating Neuro-2a cells with Aβ₁₋₄₂, and PSMD4 was overexpressed using a lentiviral vector. Flow cytometry was employed to assess reactive oxygen species (ROS) generation and mitochondrial membrane potential (ΔΨm). Quantitative PCR and Western blotting were utilized to examine the expression of mitochondrial biogenesis-associated regulators, including PGC-1α, Nrf1, Nrf2, and TFAM. For the in vivo study, APP/PS1 double-transgenic mice served as the AD model. Histological analyses (HE and Nissl staining), immunofluorescence, and Western blotting were performed to evaluate hippocampal neuronal morphology and the expression of PSMD4 and mitochondrial marker TOM20. Aβ₁₋₄₂ significantly increas
Inflammation in atherosclerosis: pathophysiology and mechanisms
Atherosclerosis imposes a heavy burden on cardiovascular health due to its indispensable role in the pathogenesis of cardiovascular disease (CVD) such as coronary artery disease and heart failure. Ample clinical and experimental evidence has corroborated the vital role of inflammation in the pathophysiology of atherosclerosis. Hence, the demand for preclinical research into atherosclerotic inflammation is on the horizon. Indeed, the acquisition of an in-depth knowledge of the molecular and cellular mechanisms of inflammation in atherosclerosis should allow us to identify novel therapeutic targets with translational merits. In this review, we aimed to critically discuss and speculate on the recently identified molecular and cellular mechanisms of inflammation in atherosclerosis. Moreover, we delineated various signaling cascades and proinflammatory responses in macrophages and other leukocytes that promote plaque inflammation and atherosclerosis. In the end, we highlighted potential the
Alzheimer's disease
Alzheimer's disease is a chronic illness with long preclinical and prodromal phases (20 years) and an average clinical duration of 8-10 years. The disease has an estimated prevalence of 10-30% in the population >65 years of age with an incidence of 1-3%. Most patients with Alzheimer's disease (>95%) have the sporadic form, which is characterized by a late onset (80-90 years of age), and is the consequence of the failure to clear the amyloid-β (Aβ) peptide from the interstices of the brain. A large number of genetic risk factors for sporadic disease have been identified. A small proportion of patients (<1%) have inherited mutations in genes that affect processing of Aβ and develop the disease at a much younger age (mean age of ∼45 years). Detection of the accumulation of Aβ is now possible in preclinical and prodromal phases using cerebrospinal fluid biomarkers and PET. Several approved drugs ameliorate some of the symptoms of Alzheimer's disease, but no current interventions can modify
Glymphatic system dysfunction predicts amyloid deposition, neurodegeneration, and clinical progression in Alzheimer's disease
INTRODUCTION: Although glymphatic function is involved in Alzheimer's disease (AD), its potential for predicting the pathological and clinical progression of AD and its sequential association with core AD biomarkers is poorly understood. METHODS: Whole-brain glymphatic activity was measured by diffusion tensor image analysis along the perivascular space (DTI-ALPS) in participants with AD dementia (n = 47), mild cognitive impairment (MCI; n = 137), and normal controls (n = 235) from the Alzheimer's Disease Neuroimaging Initiative. RESULTS: ALPS index was significantly lower in AD dementia than in MCI or controls. Lower ALPS index was significantly associated with faster changes in amyloid positron emission tomography (PET) burden and AD signature region of interest volume, higher risk of amyloid-positive transition and clinical progression, and faster rates of amyloid- and neurodegeneration-related cognitive decline. Furthermore, the associations of the ALPS index with cognitive decline
