摘要 目的探寻MicroRNAs(miR)103、107在2型糖尿病(T2DM)合并乳腺癌患者中作用机制。方法T2DM合并乳腺癌患者248例根据数字表法随机分为研究组、Dm组、Bc组、健康组4组;采集4组禁食8 h后血液分别测量血糖浓度、雌二醇(E2)、糖化血红蛋白(HbA1c)、胰岛素及miR103、107的表达。结果Dm组、Bc组和研究组体重指数(BMI)、胰岛素抵抗指数(HOMA-IR)、HbA1c、E2和空腹胰岛素水平均显著高于健康组(P<0.05);研究组HOMA-IR水平明显高于Dm组和Bc组(P<0.05);Bc组HbA1c、E2和空腹胰岛素水平显著低于研究组和Dm组(P<0.05),研究组miR103、107表达量明显高于Dm组、Bc组和健康组(P<0.05),但Bc组miR103、107表达量明显高于Dm组(P<0.05),健康组较其他3组miR103、107表达量显著低(P<0.05),BMI、HbA1c及HOMA-IR与miR103、107表达量呈正相关作用(P<0.01)。HOMA-IR为miR103和107独立影响因素。结论miR103和107与胰岛素抵抗具有相关性,当其和雌激素一起作用时易导致T2DM合并乳腺癌产生。
