Objectives: To determine the involvement of mismatch repair (MMR) genes in oral squamous cell carcinomas (OSCCs) from younger (<45 years) and older patients.

Design: Complementary DNA microarrays were used to determine gene expression profiles. A quantitative real-time polymerase chain reaction (Q-RT-PCR) was used to measure the expression of the mismatch repair genes hPMS1, hPMS2, and hMLH1. The PMS1 protein expression was analyzed by immunohistochemistry.
