Prolonging life and preventing cancer: less sugar!

Scientists have calculated two key genes that regulate the cellular response to sugar deficiency. The first one, hTERT, encodes the enzyme telomerase, which allows cells to divide indefinitely. The second, p16, encodes a protein that suppresses tumor development.
