The body has a natural way of repairing DNA harmed through the replication process, and researchers from UTMB have now figured out how the process works — a discovery that could lead to much more effective cancer treatments and maybe even the reversal of age-related diseases. “We have so much damage (our cells are) continuously being exposed to, so we have to have a very efficient system of repair before that damage is replicated,” said lead author Dr. Sankar Mitra. “If repair doesn’t occur first, replication is going to happen with the damaged genome.”
