Base Excision Repair: Base excision repair (BER) is the major pathway for correcting most spontaneous and oxidative DNA damage. In brief, the main steps of BER consist of: (1) excision of the damaged base (e.g. 8-oxoguanine), (2) incision of the DNA backbone at the abasic site product, (3) removal of the abasic terminal fragment, (4) gap-filling synthesis, and (5) ligation of the final nick. Our focus has been to understand the molecular mechanisms of repair of abasic sites and oxidative DNA single strand breaks, and to define the coordinated effort between the proteins of BER. Towards this end, we have isolated several BER proteins and have developed biochemical assays to assess their individual and cooperative structure-function relationships.
Dr. David Wilson completed his Ph.D. work in 1993 at Loyola University of Chicago, Stritch School of Medicine, as part of the Molecular Biology Program. Dr. Wilson then performed his postdoctoral research training at the Harvard School of Public Health until 1997, when he became a Senior Biomedical Scientist at Lawrence Livermore National Laboratory in the Biology and Biotechnology Research Program. While at Livermore, he was also briefly an adjunct faculty member at the University of California, Davis. Dr. Wilson started his present position at NIA in 2002.
