Telomere and Telomerase: Their Implications in Human Health and Disease

Abstract: Telomeres are distinctive structures, composed of tandemly repeated DNA sequences and associated proteins that cap the ends of all eukaryotic chromosomes. Telomeres are essential for maintaining the integrity and stability of eukaryotic genomes. In mammals, the length, structure, and function of telomeres have been believed to contribute to cellular and organismal phenotypes associated with cancer and aging. Telomere length is regulated by telomerase-dependent and telomerase-independent mechanisms. Drugs that directly bind to the telomeres and stabilize secondary DNA structures such as G-quadruplexes are potent inhibitors of telomerase; consequently, these could serve as new targets for cancer therapy. I will discuss what is known about the basis for the links between telomeres, aging and cancer, and some of the known and proposed consequences of telomere dysfunction in normal and cancer cells.
