IGF-1 DES and Testosterone Interaction: Synergistic | Peptide Database

Join others researching Vilon — share findings, ask questions, and learn from real experiences Vilon is a Khavinson bioregulator dipeptide (KE) consisting of lysine and glutamic acid, originally isolated from thymus gland extracts. Developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology, it acts as a molecular signaling compound that restores normal gene expression and protein synthesis in immune and epithelial cells. Research shows Vilon increases mean lifespan by 20-40% in animal studies and suppresses tumor development. Vilon works through epigenetic modulation, restoring chromatin structure and gene expression in immune cells. It stimulates thymocyte proliferation, activates T-helper cells, and increases the proliferative index in thymus tissue (from 26% to 37% in studies). The peptide modulates tyrosine phosphorylation of mitogen-activated cytoplasmic kinases and helps rejuvenate aged immune systems by restoring proper gene expression patterns.

Join others researching PNC-27 — share findings, ask questions, and learn from real experiences PNC-27 is an experimental anti-cancer peptide created by a supercomputer at SUNY Downstate Medical Center in 2000. It contains an HDM-2 binding domain from p53 (residues 12-26) linked to a cell-penetrating domain. The peptide selectively kills cancer cells by binding to HDM-2 (MDM2) expressed on cancer cell membranes, forming pores that cause cell necrosis. Critically, PNC-27 has no effect on normal cells because healthy cells don't express HDM-2 on their membranes. Research shows effectiveness against pancreatic cancer, breast cancer, leukemia, and melanoma. PNC-27 exploits a unique vulnerability of cancer cells: the presence of HDM-2 (human double minute 2, also called MDM2) on their cell surface. The peptide's p53 residues adopt a conformation that binds directly to membrane-bound HDM-2, inducing transmembrane pore formation. This causes rapid tumor cell necrosis (not apoptosis). Additionally, PNC-27 enters cancer cells and disrupts mitochondrial membranes. Normal cells lack surface HDM-2 expression and are completely spared.
