Core Tip

Core tip: There are discrepancies in reports concerning the association between polymorphisms in genes involved in the base excision DNA repair pathway (OGG1, APE1, and XRCC1) and colorectal cancer susceptibility. This study examines four of these polymorphisms in a Chinese Han population from the southwest region of China. Results show that the APE1 148 Glu/Glu genotype is associated with an increased risk of CRC. Moreover, analyses examining gene-behavior interactions revealed that smoking may influence the relationship between the XRCC1 Arg399Gln polymorphism and CRC risk.
