Abstract

MicroRNAs (miRNAs or miRs) are a family of small non-coding RNAs that function as oncogenes or tumor suppressor genes. Recent evidence suggests that the pri‑miR‑34b/c rs4938723 variant is associated with the development of cancer. At present, there is an inconsistent association between the single‑nucleotide polymorphism in pri-miR-34b/c and cancer in the limited studies. The present study is a case‑control investigation, with 263 breast cancer (BC) patients and 221 control women, which examined the potential association of the pri‑miR‑34b/c rs4938723 polymorphisms with BC susceptibility. The polymorphisms were genotyped by the polymerase chain reaction restriction fragment length polymorphism method. No significant association between the pri‑miR‑34b/c rs4938723 variant and BC was identified [TC vs. TT: Odds ratio (OR), 0.87; 95% confidence interval (CI), 0.60‑1.26; P=0.506; CC vs. TT: OR, 1.22; 95% CI, 0.61‑2.47; P=0.600; TC+CC vs. TT: OR, 0.91; 95% CI, 0.64‑1.31; P=0.648; CC vs. TT+TC: OR, 1.32; 95% CI, 0.67‑2.59; P=0.498; C vs. T: OR, 0.99; 95% CI, 0.75‑1.31; P=0.986]. However, a significant association was observed between the pri‑miR‑34b/c rs4938723 genotypes and clinicopathological characteristics, such a grade, progesterone receptor and human epidermal growth factor receptor 2 status were observed (P<0.05). These findings suggest that the pri‑miR‑34b/c rs4938723 variant may not be a risk factor for the development of BC.
