In this episode of The Science of Age-less Living, Dr. Ethan dives deep into the fascinating world of peptides — the tiny but powerful molecular messengers that play a central role in how we age.

You’ll discover how peptides are encoded in your genes, follow the remarkable cellular factory process of transcription and translation that builds them, and learn how these short chains of amino acids act as precise keys that unlock cell receptors and even function as transcription factors to control entire gene networks.

The episode explores the full journey: from DNA blueprint to receptor signaling, and finally to the rapid breakdown and recycling that keeps cellular communication sharp and efficient. Along the way, Dr. Hausman-Marquis explains why youthful peptide signaling is key to reducing inflammation, boosting repair, keeping stem ce ...
