Loss of Splicing Homeostasis as a Hallmark of Aging
Alternative splicing is a fundamental mechanism that ensures accurate gene expression, supports cellular adaptability, and expands protein diversity beyond the limits of a fixed gene pool. With aging, splicing fidelity weakens, contributing to decline in RNA homeostasis and disrupting essential cellular functions, including mitochondrial oxidative phosphorylation, genome stability, and immune regulation, and in turn accelerating tissue and organ dysfunction. Evidence from senescent cells, aged...

Toward neuroanatomical and cognitive foundations of macaque social tolerance grades
The macaque genus includes 25 species with diverse social systems, ranging from low to high social tolerance grades. Such interspecific behavioral variability provides a unique model to tackle the evolutionary foundation of primate social brain. Yet, the neuroanatomical correlates of these social tolerance grades remain unknown. To address this question, we expressed social tolerance grades within a novel cognitive framework and analyzed post-mortem structural scans from 12 macaque species. Our...
