Reprogramming Genes
Run Time: 3:51
NOVA PBS brings the latest from the world of science. This episode focused on epigenetics, which is the study of small chemical tags that attach themselves to genes. The genes are then turned on or off based on the nature of the tag. The pattern of tags, the epigenome, changes as we age. It’s thought lifestyle habits affect our epigenome, both good and bad. Recent breakthroughs in understanding epigenetics have come from treating patients with a specific type of leukemia. Half of those treated experienced complete remission of the disease, and twenty-five percent show improvement. Scientists warn this isn’t a “magic bullet” cure.
