Tracking cancer’s immortality factor

Canadian scientists have achieved a first in the study of telomerase, an essential enzyme implicated in aging and cancer.

In today’s edition of the prestigious journal Molecular Cell, scientists from Université de Montréal used advanced microscopy techniques to see single molecules of telomerase in living .

A flaw in the replication of chromosomes means that they get shorter with each . If nothing is done to correct this error, replication stops and cells go into a state called senescence, a hallmark of aging. Normally, telomerase adds extra DNA to the ends of chromosomes to prevent this problem, but as we age our bodies produce fewer of them.
