The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer. LA JOLLA, CA—DNA repair proteins act like the body’s editors, ...

Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from IOCB Prague has now described in detail how cells repair this damaged ...

A new study led by researchers at the University of Pittsburgh (Pitt) and UPMC Hillman Cancer Center has shown that an enzyme called PARP1 is involved in the repair of telomeres, the lengths of 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 ...

The repair of damage to genetic material (DNA) in the human body is carried out by highly efficient mechanisms that have not yet been fully researched. A scientific team has now discovered a ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

Throughout the course of our lives, DNA can break in response to natural and environmental factors. However, our bodies have dedicated enzymes and pathways which can repair our broken DNA back ...

Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and ...

The following Q&A is an edited version of the podcast. What are enzymes and how they operate? Enzymes are the molecules in our bodies that facilitate reactions. They perform this function at their ...

Protecting skin from photoaging and photocarcinogenesis requires not only sunscreen — ideally a mineral sunscreen with iron oxide — but also use of topical antioxidants, including polyphenols, and ...

A new family of enzymes enables precise cuts in single-stranded DNA, offering powerful new tools for genetic engineering and expanding possibilities in biotechnology. (Nanowerk News) A few years ago, ...
