BER genes expression in oral and pre-oral cancer: Combinatorial approach to propose potential biomarker.

Abstract excerpt

OBJECTIVE: DNA repair genes and their variants have been found to alter the risk of oral cancer. METHOD: The level of expression of XRCC3, NBS1, and OGG1 genes among 20 cases of oral cancer, 6 pre-oral cancer, and 50 healthy control subjects was measured with RT-PCR. All the subjects were also genotyped for XRCC3 rs861539 C>T, NBS1 rs1805794 C>G, and OGG1 rs1052133 C>G polymorphisms by the PCR-RFLP method; their...
