Rhesus Macaque Model of Mismatch Repair-Deficient Colorectal Cancer (RRBS)
Colorectal cancer (CRC) remains the third most common cancer in the US, with 15% of cases displaying Microsatellite Instability (MSI) secondary to Lynch Syndrome (LS) or somatic hypermethylation of the MLH1 promoter. A cohort of rhesus macaques from our institution developed spontaneous mismatch repair deficient (MMRd) CRC with a notable fraction harboring a pathogenic germline mutation in MLH1. DNA methylation and transcriptome analysis was performed to evaluate the rhesus macaque as a model organism to study carcinogenesis, develop immunotherapies and vaccines, and implement chemoprevention approaches pertinent to sporadic MSI-H and LS CRC in humans.
