Hsa-miR-423 rs6505162 Is Associated with The Increased Risk of Breast Cancer in Isfahan Central Province of Iran.

ABSTRACT: Objective:Thirteen million cancer deaths and 21.7 million new cancer cases are expected in the world by 2030. Breast cancer is considered as the main cause of cancer mortality in women aged 20-59 years. microRNAs (miRNAs) regulate gene expression at the post-transcriptional level and they are highly expressed in malignancies, including breast cancer. The role of miRNAs in the pathogenesis of breast cancer is not fully understood. In the present study, for the first time, the impact of hsa-miR-423 rs6505162 on breast cancer risk was investigated in the central province of Iran, Isfahan. Materials and Methods:This case-control study was conducted on 153 clinicopathological proven breast cancer patients and 153 sex-matched healthy women with no history of any cancer type and relative patients. The patients and controls were genotyped and association of their clinical characteristics with hsa-miR-423 rs6505162 genotype was analyzed. Results:The findings indicated that CC genotype of hsa-miR-423 rs6505162 was associated with the increased risk of breast cancer [odds ratio (OR)=2.37, 95% confidence interval (CI)=1.29-4.35 and P=0.0023, CC vs. AA]. Conclusion:The data suggested that hsa-miR-423 rs6505162 could be considered as a novel risk factor in breast cancer pathogenesis in Isfahan province of Iran.
