Major Goals: We hypothesize that colonic stem cells (CSCs) that lose MMR function will gain a selective advantage over neighboring MMR-proficient cells, particularly in a mutagenic environment such as may be found in the colon. The proposed aims utilize novel approaches to study the mechanism by which loss of MMR function contributes to tumorigenesis providing information that may help explain disease penetrance while guiding the diagnosis, prevention and treatment of Lynch Syndrome-associated cancers.
