heteromeric类固醇运输车有机溶质转运体α/β(OSTalpha /β,SLC51A / B)被发现在10年前,但其生理意义在肝脏仍不确定。一个重大的挑战是缺乏合适的模型表达OSTalpha /β。基于观察首次报道,在非酒精性脂肪肝炎肝OSTalpha /β是调节,本研究的目的是开发一个体外模型评估OSTalpha /β函数和与毒品和胆汁酸的交互。OSTalpha /β表达在人类肝脏组织分析了定量rt - pcr,免疫印迹和免疫荧光。放射性标记的化合物被用来确定OSTalpha / beta-mediated传输建立体外模型。胆汁酸和药物的影响,包括那些与淤胆型药物引起的肝损伤相关,OSTalpha / beta-mediated交通评估。OSTalpha /β的表达升高患者的肝脏非酒精性脂肪肝炎和原发性胆汁胆管炎,而肝细胞表达OSTalpha /β低控制肝组织。研究小说中细胞系统显示快速和线性OSTalpha / beta-mediated传输所有测试化合物:硫酸脱氢表雄酮,地高辛,雌激素酮硫酸盐和牛磺胆酸盐。26个化合物的相互作用研究揭示小说OSTalpha /β-抑制剂:胆汁淤积的生物标志物,glycochenodeoxycholic酸;的主要代谢物troglitazone troglitazone硫酸盐; and a macrocyclic antibiotic, fidaxomicin. Additionally, some drugs (e.g., digoxin) consistently stimulated taurocholate uptake in OSTalpha/beta-overexpressing cells. Our findings demonstrate that OSTalpha/beta is an important transporter in liver disease and imply a role for this transporter in bile acid-bile acid and drug-bile acid interactions, as well as cholestatic drug-induced liver injury. NEW & NOTEWORTHY The organic solute transporter OSTalpha/beta is highly expressed in hepatocytes of liver tissue obtained from patients with nonalcoholic steatohepatitis and primary biliary cholangitis. OSTalpha/beta substrates exhibit rapid, linear, and concentration-driven transport in an OSTalpha/beta-overexpressing cell line. Drugs associated with hepatotoxicity modulate OSTalpha/beta-mediated taurocholate transport. These data suggest that hepatic OSTalpha/beta plays an essential role in patients with cholestasis and may have important clinical implications for bile acid and drug disposition.
