Interaction of XRCC1 Arg399Gln Polymorphism and Alcohol Consumption Influences Susceptibility of Esophageal Cancer

Figure 1

The XRCC1 Arg399Gln locus was amplified by PCR and PCR products were digested with Msp I to detect the 3 possible genotypes. Lane M: 100 bp DNA Marker I; Lanes 1-2, Gln/Gln; Lanes 3-4, Arg/Arg; Lanes 5-6, Arg/Gln.
