Somatotropic Signaling Modulation by a GHRH Analogue: Mechanistic Notes on Tesamorelin and Related Research

by Rawamino | Nov 25, 2025 | Peptides

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...

Telomere Dynamics, p53–Autophagy Signaling, and Circadian Control: Mechanistic Links Relevant to Cellular Aging

by Rawamino | Nov 24, 2025 | Peptides

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...

Monoaminergic Reuptake Inhibition and Energy Balance: Mechanistic Perspectives on Tesofensine

by Rawamino | Nov 24, 2025 | Peptides

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...

Telomeric Dynamics and the Pineal Tetrapeptide Epithalon: Mechanistic Observations in Experimental Systems

by Rawamino | Nov 23, 2025 | Peptides

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...

Comparative Mechanisms of Semax and Noopept in Experimental Neurobiology

by Rawamino | Nov 23, 2025 | Peptides

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,...

Delta Sleep-Inducing Peptide (DSIP): Mechanistic Perspectives and Experimental Evidence Across Neuroendocrine Systems

by Rawamino | Nov 22, 2025 | Peptides

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...
