Latest DNA repair Stories
Oxidative stress is the cause of many serious diseases such as cancer, Alzheimer's, arteriosclerosis and diabetes.
In eukaryotes – the group of organisms that include humans – a key to survival is the ability of certain proteins to quickly and accurately repair genetic errors that occur when DNA is replicated to make new cells.
Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), through a combination of time-lapse live imaging and mathematical modeling of a special line of human breast cells, have found evidence to suggest that for low dose levels of ionizing radiation, cancer risks may not be directly proportional to dose.
Looking for ways to halt the uncontrolled growth of cancer cells, scientists at Johns Hopkins have found that a new class of drugs, called PARP inhibitors, may block the ability of pre-leukemic cells to repair broken bits of their own DNA, causing these cells to self-destruct.
The BioSciences Magazine EurekaMag.com publishes insights into specific topics in the biological sciences.
Shortening end caps on chromosomes in human cervical cancer cells disrupts DNA repair signaling, increases the cells’ sensitivity to radiation treatment and kills them more quickly.
Working with lab cultures and mice, Johns Hopkins scientists have found that a strain of the common gut pathogen Bacteroides fragilis causes colon inflammation and increases activity of a gene called spermine oxidase (SMO) in the intestine.
Scientists of the German Cancer Research Center have discovered an alternative mechanism for the extension of the telomere repeat sequence by DNA repair enzymes.
