Scientists decipher mechanisms underlying the biology of aging

02-Nov-2017

Key points from article :

Used a combination of engineering, computer science and biology to analyze molecular processes.

Chromatin silencing helps protect DNA from damage.

Also stops RNA expression so excessive silencing could derail normal cell physiology.

Cells switch their DNA between states periodically during aging.

When cells grow old, they lose their ability to maintain this periodic switching.

The study was published in the Proceedings of the National Academy of Sciences.
