Latest DNA repair Stories
Biomethylation of arsenic compounds appears to cause oxidative DNA damage and to increase their carcinogenicity.
Scientists at the John Innes Centre in Norwich, UK, have shown how plants can protect themselves against genetic damage caused by environmental stresses.
The DNA of each human cell is damaged many times every day. DNA lesions can be caused by ultraviolet radiation, errors in cell division, DNA-damaging chemicals or intracellular metabolic products.
The seeming invincibility of cancerous tumors may be crumbling, thanks to a promising new gene therapy that eliminates the ability of certain cells to repair themselves.
Researchers report that a single-stranded DNA-binding protein (SSB), once thought to be a static player among the many molecules that interact with DNA, actually moves back and forth along single-stranded DNA, gradually allowing other proteins to repair, recombine or replicate the strands.
A study published in the October issue of Nature Genetics demonstrates that loss of the tumor-suppressor protein p53, coupled with elimination of the DNA-maintenance protein ATR, severely disrupts tissue maintenance in mice.
Understanding how serious breaks in DNA are repaired may help researchers to make cancer therapy more effective.
ROYAL PALM BEACH, Fla., Sept. 29 /PRNewswire/ -- The first anti-aging doctor to offer TA-65 treatment in the U.S., has discovered a way to apply similar technology to skin care. TA-65 is the newest and most dramatic technology in the world of life extension.
For years, health conscious people have been taking antioxidants to reduce the levels of reactive oxygen in their blood and prevent the DNA damage done by free radicals, which are the result of oxidative stress. But could excessive use of antioxidants deplete our immune systems?
While Fanconi anemia (FA) is a rare and dangerous disease, new laboratory research at The University of Texas M. D. Anderson Cancer Center shows it may lead researchers toward clues in more common diseases, including highly hereditary types of breast cancer.
