University of Sheffield Scientists from the University of Sheffield have unlocked one of the secrets to DNA repair —helping doctors identify DNA base damage and a patient's susceptibility to certain types of cancer. Groundbreaking research led by Dr David Williams from the University of Sheffield's Department of Chemistry and an international collaboration of expert researchers has discovered how some proteins recognize damaged bases within DNA which, if untreated, could lead to...

Clemson University researchers recently reported finding a new class of DNA repair-makers. Clemson biochemist Weiguo Cao studies how cells repair damaged DNA. The finding from Cao's lab in the Clemson Biosystems Research Complex in collaboration with computational chemist Brian Dominy appeared in the Sept. 9 issue of The Journal of Biological Chemistry: "A new family of deamination repair enzymes in the uracil DNA glycosylase superfamily by Hyun-Wook Lee, Brian N. Dominy and Weiguo Cao."...

The human immunodeficiency virus (HIV), the cause of AIDS, makes use of the base excision repair pathway when inserting its DNA into the host-cell genome, according to a new study led by researchers at the Ohio State University Comprehensive Cancer Center "“ Arthur G. James Cancer Hospital and Richard J. Solove Research Institute. Crippling the repair pathway prevents the virus from completing this critical step in the retrovirus's life cycle. The findings offer potential new targets...

Adding a new link to our understanding of the complex chain of chemistry that keeps living cells alive, a team of researchers from the University of Vermont (UVM), the University of Utah, Vanderbilt University and the National Institute of Standards and Technology (NIST) has demonstrated for the first time the specific activity of the protein NEIL3, one of a group responsible for maintaining the integrity of DNA in humans and other mammals. Their work reported last week* sheds new light on a...
