3	How does attenuation of TUG cleavage promote obesity in physiological condition… The authors conclude that attenuation of this pathway could promote obesity, but the abstract lacks mechanistic evidence for how reduced TUG cleavage leads to w… gap-pubmed-20260410-155343-031c6b0d	open	0.820	metabolism	2026-04-10	Open →
4	What determines the nuclear translocation specificity of the TUG C-terminal cle… The abstract shows the TUG C-terminal fragment enters the nucleus and binds PPARγ/PGC-1α, but the molecular mechanisms governing this translocation and binding … gap-pubmed-20260410-155343-8878ee2f	open	0.800	metabolism	2026-04-10	Open →
5	How does cytosolic Ca2+ activation of CAMKII mechanistically regulate multiple… The study shows CAMKII activation affects mitochondrial oxidation, lipolysis, and gluconeogenesis, but the specific molecular mechanisms linking one kinase to t… gap-pubmed-20260410-155408-a7712b40	open	0.800	metabolism	2026-04-10	Open →
6	What are the physiological ligands or activators of the orphan receptor PAQR4? PAQR4 is described as an orphan receptor with unknown ligands, yet it has potent metabolic effects. Identifying its natural activators would reveal upstream reg… gap-pubmed-20260410-155413-25d3b075	open	0.790	metabolism	2026-04-10	Open →
7	What molecular mechanisms link PTEC-specific enhanced autophagy to systemic met… The study demonstrates that RUBCN deficiency in PTECs leads to metabolic syndrome features, but the mechanistic pathway connecting local kidney cell autophagy t… gap-pubmed-20260410-155350-f66a64a8	open	0.790	metabolism	2026-04-10	Open →
8	How does the TUG cleavage pathway contribute to the thermic effect of food in h… The authors suggest this mechanism might contribute to the thermic effect of food but provide no direct evidence. Understanding this connection could reveal new… gap-pubmed-20260410-155343-d18dc08a	open	0.790	metabolism	2026-04-10	Open →
