    Abstract:
    The association studies between miR-34b/c rs4938723 polymorphism and cancer risk showed conflicting results. This study aimed to assess the impact of rs4938723 polymorphism on prostate cancer risk. This case-control study was done on 151 prostate cancer (PCa) patients and 152 benign prostate hyperplasia to examine whether rs4938723 polymorphism in the promoter of pri-miR-34b/c was linked to the carcinogenesis of PCa in a sample of Iranian population. Genotyping of Pri-miR-34 b/c rs4938723 polymorphism was performed by using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method. The results showed that rs4938723 variant significantly increased the risk of PCa in codominant (OR = 1.92, 95% CI = 1.15 - 3.18, p= 0.012, TC vs TT), dominant (OR = 1.99, 95% CI = 1.23 - 3.24, p= 0.005, TC + CC vs TT), and allelic (OR = 1.79, 95% CI = 1.20 - 2.68, p= 0.005, C vs T) inheritance model. Our findings propose that Pri-miR-34 b/c rs4938723 variant may be a risk factor for the development of PCa in a sample of Iranian population. Larger sample sizes with different ethnicities are required to validate our findings.
