Telomeres, telomerase and cancer

Bulletin du cancer
J C Soria, O Rixe

Abstract

The chromosome ends are specialized nucleoprotein structures called telomeres, which length predicts replicative capacity of cells. Activation of telomerase, the DNA polymerase that synthesizes telomeric repeats, seems to be necessary for cells to become immortal. Methods of measuring telomerase activity, now reliable and semiquantitative, have shown that telomerase is expressed in most human cancers, but not in normal somatic tissues. Research about regulation of telomere length and telomerase activity, highlights connexions between senescence and cancer. This article details diagnosis, prognosis and therapeutic prospects linked to the study of telomerase activity.

Cancer Epigenetics and Senescence (Keystone)

Epigenetic changes are present and dysregulated in many cancers, including DNA methylation, non-coding RNA segments and post-translational protein modifications. The epigenetic changes may be involved in regulating senescence in cancer cells. This feed captures the latest research on cancer epigenetics and senescence.
