Regulatory RNA essential to DNA damage response

Stanford researchers have found that a tumor suppressor known as p53 is stabilized by a regulatory RNA molecule called DINO. The interaction helps a cell respond to DNA damage and may play a role in cancer development and ...

Senescence or biological aging is the change in the biology of an organism as it ages after its maturity. Such changes range from those affecting its cells and their function to those affecting the whole organism. There are a number of theories as to why senescence occurs; for example, some posit it is programmed by gene expression changes, others that it is the cumulative damage caused by biological processes. Senescence is not the inevitable fate of all organisms. A variety of organisms, including some cold-blooded animals, have negligible senescence. Whether senescence as a biological process can be slowed down, halted or even reversed, is a subject of current scientific speculation and research.

The word senescence is derived from the Latin word senex, meaning old man, old age, or advanced in age.
