MOTS-c & Mitochondrial Peptides in Health & Aging | David Lee | Episode 302 (opens the original)
Read excerpt
Send us Fan Mail Mitochondrial peptide MOTS-c is a stress-induced signal that reprograms cell metabolism. TOPICS DISCUSSED: Mitochondrial Roles: Not just ATP production, but “speaker of the house” via communication molecules that “talk” to the rest of the cell.Origin of Communication: Mitochondrial peptides were likely co-opted from ancient antimicrobial factors to synchronize nuclear and mitochondrial genomes.MOTC Discovery: Identified in mitochondrial ribosomal RNA regions linked to interfe...
Peptides & GHK-Copper in Skin Health | Rahi Sarbaziha | Episode 301 (opens the original)
Read excerpt
Send us Fan Mail GHK-Copper and peptides in skin care, aging, and general health. TOPICS DISCUSSED: Endogenous Decline: GHK-copper levels peak in young adulthood then fall with age, reducing natural support for skin repair and collagen maintenance.Skin Penetration: Effective topical delivery depends on molecular size under and fat solubility, often improved by procedures such as microneedling that briefly disrupt the barrier.Mechanisms of Action: The peptide upregulates fibroblasts and vascul...
Peptides & Blood-Brain Barrier in Health & Disease | William Banks | Episode 300 (opens the original)
Read excerpt
Send us Fan Mail Blood-brain barrier as a dynamic interface allowing selective passage of nutrients, peptides, and gut hormones. TOPICS DISCUSSED: Blood-Brain Barrier Structure: Capillary endothelial cells with tight junctions, absent fenestrae, and minimal vesicles create a selective interface; supported by astrocytes and pericytes.Crossing Mechanisms: Lipid-soluble small molecules diffuse passively; glucose, amino acids, and regulatory peptides use saturable transporters whose rates vary by...
Iron Overload & Lipid Peroxidation in Cell Death & Neurodegenerative Disease | Pamela Maher | Episode 299 (opens the original)
Read excerpt
Send us Fan Mail Ferroptosis, an iron-dependent cell death pathway driven by lipid peroxidation; chronoferoptosis, in which chronic stress sensitizes neurons gradually. TOPICS DISCUSSED: Cell Death Pathways: Apoptosis proceeds through regulated steps with surface “eat me” signals that enable non-inflammatory clearance by phagocytes, whereas ferroptosis and related pathways release cellular contents that can amplify local damage and inflammation.Ferroptosis Discovery: Work on glutamate toxicit...
