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 ...

Our genome is organized into chromosomes, which are shaped like little X's. Every time a cell divides, the genome has to be replicated, and there are protective caps called telomeres on the ends of ...

In the quest to unlock the secrets of aging and longevity, telomeres have emerged as key players. These protective caps at the ends of our chromosomes play a critical role in cellular aging. With each ...

Shorter LTL is associated with total and regional brain structure and a higher risk of incident dementia and AD, implying the potential of telomere length as a predictive biomarker of brain health.

O'Sullivan hypothesizes that ADP-ribose affects telomere integrity by disrupting a protective structure called shelterin that safeguards telomeres, but more research is needed to confirm this.

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University have ...
