Relationship between rs6715345 Polymorphisms of MIR-375 Gene and rs4939827 of SMAD-7 Gene in Women with Breast Cancer and Healthy Women: A Case-Control Study
چکیده انگلیسی:
Background: Today, the role of microRNAs in the pathogenesis of breast cancer has been established. Genetic mutations play a significant role in determining the risk factors of cancer. The polymorphism of these two genes can alter their expression. This study has been performed to investigate the relationship between polymorphisms of rs6715345 of miR-375 gene and rs4939827 of the SMAD7 gene and development of breast cancer in a population in southeastern Iran. Methods: This case-control study was performed on the blood sample of 205 patients with breast cancer and 200 healthy individuals for investigating the rs34917480 and rs4939827 polymorphisms using the PCR-RFLP method. The data were analyzed by t-test, χ2, and logistic regression. The SPSS v18.0 used for data analysis. Results: The findings of this study indicated that the risk of developing breast cancer does not have a significant relationship with rs6715345 polymorphism of miR-375 gene (p<0.1). However, the rs4939827 polymorphism of the SMAD7 gene was significantly linked to the risk of developing breast cancer in the southeastern population in Iran (p>0.01). Conclusion: The results suggest that the rs4939827 polymorphism of the SMAD7 gene can lead to an increased risk of incidence of breast cancer in the southeastern population in Iran.
