Genetics Of Aging - iBiology & Youreka Science

Why do some people age more quickly than others? This video describes pioneering research performed by the biologist Cynthia Kenyon, who hypothesized that genes could control the rate of aging. To figure out which genes regulate aging, scientists in Dr. Kenyon’s lab made mutations in the DNA of a tiny worm called C. elegans and looked to see which mutations caused the worms to live longer, healthier lives. Amazingly, modifying just one gene, called Daf-2, allowed the worms to live twice as long as normal. Daf-2 is a conserved gene found in flies, mice, and humans, so its activity may regulate aging in our species as well.

It would deserve at least millions of views!!!!

My grandmother was 98 when she died. She had 11 children. Only 5 lived past 80 and only 2 over 90. Her own parents died in their 20s (mother) and at 70 (father).

Is by any chance the daf 2 gene present at the telomeres? Since the shortening of telomere is also related to aging as the cell progresses division.

So soaking in thermal baths may de-activate the DAF2 gene in Humans and extend lifspan? Bob- Hot Springs ARK.

This cartoon version of iBiology series of lectures I like the least. Luckily, the source -- Dr Kenyon presentation -- is right there in youtube sideview...

IM SO F*CKING CONFUSED I SEE A HAIRY MEN HAND AND I HEAR WOMAN VOICE


ps, what if you remove this worm would you age faster or not at all?
