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 ...

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 ...

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.

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.

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 ...

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 ...

Forbes contributors publish independent expert analyses and insights. Telomeres, the protective caps at the ends of our chromosomes, act much like the plastic tips of shoelaces, preventing our DNA ...

A new study led by University of Pittsburgh and UPMC Hillman Cancer Center researchers shows that an enzyme called PARP1 is involved in repair of telomeres, the lengths of DNA that protect the tips of ...
