A reanalysis of whole-genome data from 130 children conceived after the Chernobyl disaster has identified a statistically significant increase in a specific type of DNA mutation in the offspring of ...

Bowel cancer cells have the ability to regulate their growth using a genetic on-off switch to maximize their chances of survival, a phenomenon that's been observed for the first time by researchers at ...

There are some genes that can promote cancer; they are sometimes called oncogenes, and in tumor cells, mutations are often found in these genes. When they are functioning normally, oncogenes are often ...

While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

How bladder cancer originates and progresses has been illuminated as never before. Researchers found that antiviral enzymes that mutate the DNA of normal and cancer cells are key promoters of early ...

What Is the MTHFR Gene Mutation? The MTHFR gene mutation is a variation in the MTHFR gene. This gene normally tells your body how to make the MTHFR protein. You need this protein to process folate, ...

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

What do your genes have to do with growing old? Quite a lot. But is it due to the actual DNA, or the way those genes are expressed? KPBS sci-tech reporter Thomas Fudge has more on new research that ...

BRCA gene mutations can significantly raise a woman’s risk of breast and ovarian cancer. Know how hereditary cancer risk works and why genetic testing and early screening matter.

Cancer is often thought of as a single disease. Yet even tumors that arise in the same organ can follow very different ...
