What does epigenetics really mean?

There’s a phrase that get’s thrown around a lot these days, particularly in the longevity space. And that phrase is Sheekey Science. But there’s another word you may also hear about and that is epigenetic reprogramming. I am guilty myself of throwing this word around without really explaining what i mean by this. I’ve discussed reprogramming before, but i want to discuss in this video what is really meant by the phrase epigenetics, as And it goes beyond me, do you really know what they means by that term. Well, by the end of this video, you will have my interpretation of the term which has come from the science literature that i;ve read, and for fun, i’ll throw in other scientists definitions too. In particular i will focus mainly on the link between epigenetics, gene expression and cell identity - what makes a happy healthy cell do what it does best. And i think by the end of it you will have 3 main take homes; (i) an appreciation of genome organisation & cell identity - with some shocking surprises (ii) an overview of the different classes of epigenetics (iii) modern day & epigenetic reprogramming TIMESTAMPS: Intro - 00:00 DNA packing & chromatin organisation - 01:05 Histone marks - 05:15 DNA methylation - 06:20 RNA - 07:57 Epigenetic reprogramming - 09:45 References: https://asheekeyscienceblogcom.wordpr...
