circRNA dysregulation as neurodegeneration biomarker and exploratory therapeuti…

Mechanistic description

Neuronal circRNAs may reflect synaptic, mitochondrial, and RNA-regulatory disruption in neurodegenerative disease. The strongest near-term use is biomarker discovery and stratification; therapeutic manipulation remains low-confidence because causality, stoichiometry, delivery, and m6A specificity are unresolved.

neurodegeneration

Evidence for (3)

circHomer1 is reduced in AD prefrontal cortex, supporting disease-associated circRNA changes.

PMID:31078105
circCfl1 has been linked to mitochondrial dynamics biology.

PMID:31624252
m6A modification can regulate circRNA decay, creating a plausible regulatory mechanism.

PMID:29600559

Evidence against (2)

Postmortem circRNA changes may reflect neuronal loss, cell-type composition, RNA quality, agonal state, medication, inflammation, or disease stage rather than causal biology.

PMID:31078105
Broad m6A manipulation affects many RNAs and is unlikely to provide specific therapeutic control over individual circRNAs without safety concerns.
