Telomerase restores short bits of DNA known as telomeres, which are otherwise shortened after repeated division of a cell via mitosis. In normal circumstances, where telomerase is absent, if a cell divides recursively, at some point the progeny reach their Hayflick limit, which is believed to be between 50 and 70 cell divisions. At the limit the cells become s… Webb30 juli 2024 · Approaches to targeting telomerase include: (1) Immunotherapies—peptide or DNA vaccines supply immunogenic TERT epitopes that stimulate immune responses against telomerase-expressing cancer ...

WebbIn our bodies, telomerase is usually shut off. It is turned on when making sperm and eggs and in some very early stages of life – in cells that will have to divide a lot. And it is turned on when cells become cancerous. Cancer cells may reactivate telomerase by changing the DNA around one of the genes that makes telomerase, called TERT.
