Enzyme That Influences Aging, Cancer Decoded: Study

Enzyme That Influences Aging, Cancer Decoded: Study


Elated scientists announced Wednesday the completion of a 20-year quest to map the complex enzyme thought to forestall aging by repairing the tips of chromosomes in plants and animals, including humans.

Decoding the architecture of the enzyme, called telomerase, could lead to drugs that slow or block the aging process, along with new treatments for cancer, they reported in the journal Nature.

“It has been a long time coming,” lead investigator Kathleen Collins, a molecular biologist at the University of California in Berkley, said in a statement. > >> read more ...

John Sulston, Who Decoded the Human Genome, Dies at 75


LONDON (AP) — John Sulston, a Nobel Prize-winning British scientist who helped decode the human genome, has died. He was 75.

The Wellcome Sanger Institute, the successor to the cutting-edge genomic research center he once founded and directed, confirmed Friday that Sulston had died but did not say when or give the cause of death.

Sulston shared the prize in 2002 for his contribution to work in unraveling how genes control cell division. He traced the adult nematode worm, C. elegans, to decipher how cells divide and create something new — findings the institute said were key to understanding how cancers develop. > >> read more ...
