Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from ...

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, ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

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 ...

Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from ...

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 ...

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 ...

There are many health problems that can be traced back to errors in the genetic code. There are also many potential benefits to genetic engineering outside of healthcare. Nature has already found ways ...

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, ...

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 ...
