Introduction Coordinated regulation of growth hormone (GH) relies on convergent inputs from hypothalamic growth hormone–releasing hormone (GHRH) and peripheral ghrelin-family signals acting through distinct receptors on pituitary somatotrophs. In laboratory models,...

Introduction Cellular energy balance is coordinated by endocrine cues that couple nutrient status to growth, repair, and substrate selection. Central to this network is the somatotropic axis, in which growth hormone–releasing hormone (GHRH) stimulates pituitary...

Introduction Cellular aging emerges from the interplay of genome integrity, stress-response signaling, and macromolecular quality control. Telomeres—repetitive DNA–protein structures at chromosome ends—progressively shorten during replication and become dysfunctional...

Introduction Energy homeostasis emerges from coordinated neurotransmission within hypothalamic and mesolimbic circuits, peripheral metabolic signals, and adaptive changes in substrate utilization. Disruption of these networks can shift the balance between energy...

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...
