Conference : Does DNA record time?
22 novembre 2019 16:00 - Amphi Gaston Berger

What is today's date? Don't worry if you don't remember. You can always check using the timekeeping device you always have with you -- your DNA! It will rarely lie about your true age. No matter how hard you try to fight age (and fight you should!), there's no fooling our internal biological timekeeper. Recent advancements in genome sequencing have given us a glimpse how our bodies record our age. In fact, our body's long-term clock is perfectly distributed: as we age, the DNA in each cell of our bodies subtly changes. Called epigenetic modifications, these changes alter how our genes are expressed and directly influences how our cells (and our bodies) function. For now, you may need to rely on diet, exercise and (optionally) face creams to feel young. But in not-so-distant future we may be able to rewind our epigenetic clocks to make the body forget that time has passed.
