The length of telomeres that protect the ends of our chromosomes should be tightly regulated. Those that are too long predispose to cancer, and those that are too short lose their protective ability, ...
New findings describe how the enzyme CST is recruited to the end of the telomere, where it maintains telomere length with the help of subtle chemical changes made to the protein POT1. The length of ...
Much the way the caps on the ends of a shoelace prevent it from fraying, telomeres — regions of repetitive DNA sequences and a protein structure — protect the tips of chromosomes from damage. Every ...
A new computational tool infers changes occurring at the ends of the chromosomes housing our DNA. It does so by detecting structural alterations in cells and tissues captured in images taken of ...

Study sheds new light on telomerase, an enzyme tied to aging and cancer
Researchers have found a way to trap telomerase, the enzyme cancer cells rely on for endless division, in a stalled and ...
Scientists have mapped out the molecular structure of a key part of our chromosomes called telomeres, which play a pivotal part in aging and cancer. Scientists from Nanyang Technological University, ...
Longer leukocyte telomere length is associated with higher left ventricular mass (LVM) and larger global ventricular size, as well as better cardiac function and lower risk of heart failure (HF). The ...
Researchers at Arizona State University’s (ASU) School of Molecular Sciences and the Biodesign Institute’s Center for the Mechanism of Evolution have discovered an unprecedented pathway producing ...
CST (purple/lavender) bound to POT1 (red). Phosphorylation of the crimson-highlighted region in POT1 regulates the recruitment and activity of CST–Polα-primase at telomeres. The length of telomeres ...
