Genetic polymorphism of T6235C mutation in 3 non-coding region of CYP1A1 and GSTM1 genes and lung cancer susceptibility in the Mongolian population

摘要

Objective To estimate the relative risk for lung cancer associated with genetic polymorphism of T6235C mutation in 3' non-coding region(MspⅠ)of cytochrome P450 1A1(CYP1A1)and glutathione S-transferase M1(GSTM1)in the Mongolian population in Inner Mongolian Region of China.Methods Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)and multiplex PCR methods were used to analyze blood samples obtained from 263 case subjects and 263 control subjects to determine their genotypes for CYP1...
