Association of MicroRNA-149 Polymorphism with Lung Cancer Risk in Chinese Non-Smoking Female: A Case-Control Study.
PloS One 2016
INTRODUCTION: Rs2292832 is a single nucleotide polymorphism located in the precursor of mir-149 and was reported to be associated with varieties of malignancies. So far, the effect of miR-149 rs2292832 polymorphism on lung cancer risk was unclear. In addition, cooking oil fume exposure was demonstrated to be an important environmental risk factor in Chinese female. The aim of the present study was to evaluate the associations of rs2292832 polymorphism, cooking oil fume exposure and multiplicative interaction of cooking oil fume exposure and rs2292832 polymorphism with lung cancer risk in Chinese non-smoking female population.
METHODS: The present study was a hospital-based case-control study conducted in Chinese non-smoking females. 555 lung cancer patients and 395 cancer-free controls were interviewed to collect demographic data and exposure status of environmental risk factors, and then donate 10 ml venous blood which was used to be genotyped by Taqman allelic discrimination method. The statistical analyses were performed on SPSS 13.0 software.
RESULTS: The association between miR-149 rs2292832 polymorphism and risk of lung cancer(TC vs. TT: OR = 1.006, 95%CI = 0.767-1.321, P = 0.963; CC vs. TT: OR = 0.41, 95%CI = 0.532-1.329, P = 0.458; Dominant model: OR = 0.965, 95%CI = 0.745-1.251, P = 0.788; Recessive model: OR = 0.816, 95%CI = 0.528-1.259, P = 0.357, adjusted for age), non-small cell lung cancer(TC vs. TT: OR = 1.006, 95%CI = 0.767-1.321, P = 0.963; CC vs. TT: OR = 0.841, 95%CI = 0.532-1.329, P = 0.458, adjusted for age), lung adenocarcinoma(TC vs. TT: OR = 0.944, 95%CI = 0.700-1.273, P = 0.707; CC vs. TT: OR = 0.801, 95%CI = 0.485-1.323, P = 0.386, adjusted for age) and squamous cell carcinoma(TC vs. TT: OR = 1.025, 95%CI = 0.641-1.638, P = 0.919; CC vs. TT: OR = 0.792, 95%CI = 0.346-1.813, P = 0.581, adjusted for age) were all not statistically significant. Result of Logistic regression showed that the multiplicative interaction of cooking oil fume exposure and rs2292832 polymorphism was not statistically significant (P = 0.063 for lung cancer and P = 0.064 for lung adenocarcinoma).
CONCLUSION: MicroRNA-149 rs2292832 polymorphism may not be associated with lung cancer risk in Chinese non-smoking female.
