1	Why does PVN circadian enhancement specifically reverse epigenetic aging marker… The study shows PVN-targeted circadian interventions reduce DNA methylation age systemically, but the mechanism by which local hypothalamic clock strengthening … gap-pubmed-20260410-183254-7f48b75e	open	0.820	aging neurobiology	2026-04-10	Open →
2	Do white matter changes precede or follow oligodendrocyte transcriptomic dysfun… The temporal relationship between structural white matter degeneration and oligodendrocyte gene expression changes remains unclear from Allen Atlas data.

3	Do these circadian interventions extend lifespan and reverse aging biomarkers i… The study was conducted exclusively in male mice, leaving unknown whether sex differences in circadian biology, hormonal regulation, or aging processes affect t… gap-pubmed-20260410-183254-152aaf01	open	0.780	aging neurobiology	2026-04-10	Open →
4	What molecular mechanisms drive age-associated epigenetic drift and its relatio… The authors explicitly state this is a 'key missing piece of information' - the mechanistic basis for how epigenetic drift occurs and relates to methylation-bas… gap-pubmed-20260411-083130-3c3c3160	open	0.780	aging neurobiology	2026-04-11	Open →
5	What determines tissue-specific NAD+ depletion patterns in brain aging versus o… While NAD+ supplementation rescues BBB damage, it's unclear why certain brain regions or cell types are more vulnerable to age-related NAD+ decline.
