Preclinical Modulators of Bone Remodeling: Mechanistic Perspectives on BPC-157, AOD-9604, MOTS-c, and 11R-VIVIT

by Rawamino | Dec 8, 2025 | Peptides

Introduction Osteoporosis is characterized in experimental literature by reduced bone mass and altered microarchitecture that increase fracture susceptibility in animal and cell models. A growing body of preclinical work explores peptide-based probes that may...

NAD⁺ Economy, NNMT Inhibition, and Satellite-Cell Reactivation in Experimental Skeletal Muscle Models

by Rawamino | Dec 8, 2025 | Peptides

Introduction Age-associated decline in skeletal muscle function is frequently accompanied, in laboratory systems, by impaired activity of resident muscle stem cells (satellite cells; muSCs). In rodent and cell-culture models, these progenitors display reduced...

FOXO4–p53 Interactions and the Selective Removal of Senescent Cells in Experimental Systems

by Rawamino | Dec 7, 2025 | Peptides

Introduction Cellular senescence is a conserved damage-response program in which proliferative cells enter a stable, long-term arrest while remaining metabolically active. In laboratory models, senescent cells adopt distinct chromatin states, accumulate DNA damage...

Molecular Roles of Insulin-Like Growth Factor-1 (IGF-1): Pathway Architecture and Experimental Findings

by Rawamino | Dec 7, 2025 | Peptides

Introduction Insulin-like Growth Factor-1 (IGF-1) is a 70-amino-acid polypeptide within the insulin/IGF superfamily that coordinates growth and stress-response programs across diverse tissues. In laboratory systems, IGF-1 is generated downstream of growth hormone (GH)...

Mitochondrial–Nuclear Crosstalk of MOTS-c in Exercise-Driven Cardiac Adaptation: Preclinical Evidence

by Rawamino | Dec 6, 2025 | Peptides

Introduction Cardiac tissue adapts to repeated endurance loading through coordinated shifts in cellular energetics, calcium handling, and structural remodeling. These adjustments include enhanced oxidative capacity, altered hemodynamic set points, and changes in...
