Introduction Chromosome termini are capped by telomeres—hexameric TTAGGG repeats bound by shelterin proteins—that preserve genome integrity by preventing end-to-end fusion, exonucleolytic degradation, and inappropriate DNA damage signaling. Because conventional DNA...

Introduction Learning, memory formation, and cellular resilience to injury rely on coordinated transcriptional programs, synaptic plasticity, and stress-response signaling in the central nervous system. Perturbations such as excitotoxic calcium influx,...

Introduction Sleep–wake regulation emerges from interacting neural circuits, neuromodulators, and endocrine cues that shape transitions among vigilance states and sculpt electrophysiological signatures such as slow-wave (delta) activity. Despite extensive mapping of...

Introduction Progressive neurodegenerative processes in laboratory models of Parkinson’s disease (PD) and Alzheimer’s disease (AD) converge on synaptic failure, proteostasis disruption, neuroinflammation, and selective neuronal vulnerability. Canonical features...

Introduction Cellular senescence is a stress-adaptive phenotype defined by stable cell-cycle exit, altered chromatin architecture, metabolic rewiring, and a distinct secretory program. In experimental systems, senescence can be triggered by DNA damage, oncogenic...
