A cell’s ability to repair damaged DNA is key to its maintaining normal biology and protecting against cell death. But the repair process can be a two-sided coin: keeping a normal cell healthy is beneficial; keeping a malignant cell healthy can promote cancer. The mechanisms by which cells recognize and attempt to repair damage are myriad and complex; and individual DNA-repair proteins can be involved in multiple pathways. Jefferson researchers across several fields are working to understand the genomic and molecular processes at work in DNA repair—and the problems created when those processes go awry.
