Arsenic and old telomeres or Arsenic and old telomeres original from John Hopkins Medical institutes
Telomerase, the enzyme responsible for adding telomere repeats to the end of each chromosome, prevents both gradual chromosomal degradation and sudden loss of normal cell function. Because telomerase activation is one means by which cancer cells escape normal growth control, there has been considerable interest in blocking its function or expression. Now Chou et al. report that arsenic, one of the oldest known agents in medical history, has just such an effect.
