Probable effects of glutatione s-transferase p1 gene exon-6 (ala114val) polimorphism on the etiology of lung cancer

Abstract

Objectives: Genetic susceptibility also has significant effects on the etiology of lung cancer, besides smoking. Previously it has been reported that some genetic polymorphisms have important roles; especially Glutatyon S-Transferaz P1 (GSTP1) gene for the development of lung cancer. GSTP1 gene has a role in phase II of xenobiotic metabolism. GSTP1 Exon-6 polymorphisms have functional effects on gene production and causes differences in enzyme activity.The aim of this study was to investigate probable effects of GSTP1gene exon-6 (ala114val) polimorphism on the etiology of lung cancer. Materials and methods: Our research population consistsed of 160 subjects; 80 as control group and 80 suffering from lung cancer. Genomic DNA was extracted from peripheral blood leukocytes and the genotypes have been determined by using PCR and RFLP methods. Results: No effect of exon 6 (ala114val) polymorphism genotype of GSTP1 gene were found on etiology of lung cancer in present study. This study showed that smoking, old age and being male are important risk factors for lung cancer. Additionally, our sample\'s GSTP1 gene exon 6 (ala114val) polymorphism genotype frequencies were determined. Conclusions: Our data derived from present study did not suggest an effect of GSTP1gene exon-6 (ala114val) polimorphism on the etiology of lung cancer.
