What is the age of your DNA?
Steve Horvath is a UCLA professor of genetics, biostatistics, and statistics. He has developed a method to measure biological age – or a \”clock\” of sorts – by analyzing the methylation patterns of an organism’s DNA. Methylations, a biochemical process that modifies the activity of DNA segments without altering their sequence, are a form of epigenetic changes. This video primer will explain the basics of epigenetic timers. Our interview with Dr. Steve Horvath is coming soon.

Episode highlights:
* 00:00.09 — The biological age of a person is more important than the chronological age.
* 00:00.09 — Epigenetics is a term that refers to processes which can alter gene expression without changing DNA sequence. Methylation, a type epigenetic alteration that happens over the course of a lifetime and is predictable, can be used as a way to measure biological age.
* 00.01:17 — Based on epigenetic data in the blood, the Horvath clock accurately predicts a person’s chronological age.
* 00.01:54 – The GrimAge clock is able to predict cancer risk, heart disease and death.
* 00.02:19 — Some drugs can reverse epigenetic age in a person, but their effects on biological age is unknown.
* 00.03:09 – The discovery of a drug to combat aging is imminent.
