目的 探讨氡对矿井下作业人员外周血血浆miR-16、miR-106b、miR-449a、let-7g、miR-21、miR-221、miR-34a表达的影响。方法 采用简单随机抽样法分别选取矿井下作业人员(井下组)46名和矿井上作业人员(对照组)38名。采用实时荧光定量PCR (qPCR)方法,检测研究对象外周血血浆中miRNAs的相对表达水平。比较miRNAs在井下组和对照组外周血血浆中的差异表达,分析miRNAs的差异性表达与累积剂量等因素的关系。结果 井下组外周血血浆miR-106b、miR-21、miR-221明显高于对照组(Z=-2.32、-2.47、-2.79,P < 0.05),其倍数变化(Fc)分别为1.61、1.75、1.30;miR-16、miR-449a、let-7g、miR-34a高于对照组,但差异无统计学意义(P>0.05)。控制年龄、体质量指数(BMI)、吸烟等因素后,miR-16、miR-106b、let-7g、miR-21、miR-221的差异性表达和氡暴露累积剂量呈正相关(t=2.50、3.31、2.60、2.95、3.25,P < 0.05),而miR-449a、miR-34a的表达改变与氡暴露累积剂量无显著相关(P>0.05)。结论 miR-106b、miR-21、miR-221可能具有作为氡致辐射损伤的早期标志物的潜在价值。 |

Objective To investigate the effect of radon on the expressions of miR-16, miR-106b, miR-449a, let-7g, miR-21, miR-221 and miR-34a in peripheral blood plasma of miners.Methods A total of 46 randomly selected miners worked underground(the underground group)and 38 miners worked aboveground (the control group). MiRNA levels in the underground and control groups were detected by qRT-PCR and their relationship with cumulative effective dose was further analyzed.Results The levels of miR-106b, miR-21, miR-221 in plasma of the study group were significantly higher than those in the control group(Z=-2.32, -2.47, -2.79, P < 0.05), the corresponding Fc values were 1.61, 1.75, 1.30, respectively. The levels of miR-16, miR-449a, let-7g and miR-34a were slightly higher than those in the control group (P>0.05). After controlling of confounding factors such as age, BMI and smoking, the alteration of miR-16, miR-106b, let-7g, miR-21 and miR-221 in plasma of the underground group were positively correlated with the cumulative effective dose(t=2.50, 3.31, 2.60, 2.95, 3.25, P < 0.05). No significant difference was observed in the plasma levels of miR-449a and miR-34a between the two groups (P>0.05).Conclusions miR-106b, miR-21 and miR-221 could be used as potential biomarkers of radon exposure. |
