摘要
目的研究胆囊胆固醇结石病人肝脏的肝脏受体类似物1(Liver receptor homolog 1,LRH-1)及其调控的三磷酸腺苷结合盒(ABC)转运体家族成员abcg5/8的表达,探讨胆固醇结石病发病的机制。方法27例胆囊胆固醇结石病人,男6例,女21例;年龄平均52岁。10例无胆石症的胆囊息肉病人为对照,男6例,女4例;平均年龄48岁。测定胆汁脂类成分和计算胆汁胆固醇饱和指数。实时定量PCR法测定肝脏LRH-1及abcg5/8mRNA的表达量。结果胆石组LRH-1表达高于对照组(14.18±1.80VS7.22±2.22,P〈0.05),胆石组肝脏abcg基因mRNA表达量均较对照组增高(abcg5:49.34±3.68vs33.48±2.77,P〈0.05;abcg8:38.93±5.70vs18.70±3.42,P〈0.05)。胆石组胆汁呈胆固醇过饱和(1.17±0.02)。结论该研究结果提示人类肝脏LRH-1及其调控的abcg5/8的表达增高与胆囊胆固醇结石形成有关。
Objective To investigate the mRNA expression of liver receptor homolog 1 (LRH- 1) gene and abcg5/8 genes regulated by LRH-1 in patients with cholesterol gallstone disease to elucidate the biomolecular pathogenesis of gallstone formation. Methods Twenty-seven patients with cholesterol gallstone (CGS) and 10 controls without gallstones were enrolled in this study. The biliary composition was assayed, mRNA expression of LRH-1 and abcg5/8 genes was determined by RTPCR. Results The expression levels of LRH-1 and abcg5/8 genes were significantly higher in CGS patients than in controls (LRH-1 : 14. 18±1.80 vs 7.86±2.22; abcg5 :49. 34 ±3.68; abcg8 :38. 93± 5.70 vs 18.70±.42; P〈0.05). Conclusion CGS disease may be related to increased expression of LRH-1 and abcg5/8 genes.
