The association between 1349T>G polymorphism of ApE1 gene and the risk of prostate cancer in northern Iran

Abstract

Prostate cancer (PCa) is the most common malignancy in men and the fourth most common cause of death based on cancer all over the world. Many genes has been shown to be involved in the progress of the prostate cancer. Human apurinic/apyrimidinic endonuclease 1 (APE1) is a multifunctional protein that has an important role in the base excision repair (BER) pathway. The aim of this study was to evaluate the association of ApE1 1349T>G polymorphism and the susceptibility to prostate cancer in northern Iran population. Samples were collected from 100 patients diagnosed with prostate cancer patients and 100 controls subjects and genotyped by PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism). We observed a significant difference in genotype distributions of ApE1 1349T>G polymorphism between patients and controls (P= 0.039). Our findings revealed individuals with the variant TG and GG had a significant increased risk of prostate cancer (GG: OR= 2.50, 95%CI= 1.063-5.874, P= 0.035. TG: OR= 2.40, 95%CI= 1.16-4.95, P= 0.017). Also, more analyses were showed that G allele were associated with increased risk of prostate cancer (OR= 1.493, 95%CI= 1.007-2.21, P= 0.045). The data from this study indicates that the ApE1 1349T>G polymorphism is associated with increased risk of prostate cancer. Although more studies should be considered with larger number of patients and control subjects to confirm our results.
