In their study, the researchers inserted fine tubes into the spiracles of a moth to measure not only how much carbon dioxide the m...

Deficiency of growth hormone and IGF-1 reduces cancer and kidney disease, but creates other problems

... "cartilage degeneration that normally accompanies aging is accelerated by the absence of growth hormone." The researchers concluded that cancer risk as well as other age-related pathologies could be substantially decreased in these animals by inducing a modest deficiency of growth hormone and IGF-1 early...

Biochemists report discovery of structure of major piece of telomerase; implications for cancer

...the ends of shoelaces, get shorter. In the natural aging process, the telomeres eventually get so short that cells can no longer divide, and they die. While telomerase is turned off in most types of healthy cells in our bodies, it is active in the vast majority of cancer cells, Feigon said. Because cancer...
