Studies on the inhibitory mechanism of Crocodylus siamensis bile extract on cholangiocarcinoma cells

Abstract

胆管癌是起源于肝内或肝外胆管上皮的恶性胆道肿瘤。由于胆管癌的早期症状不明显、发现困难,一旦发现多数已进入晚期,很难通过手术方法切除治疗,因此,寻找其他非手术方法治疗胆管癌就变得十分必要。目前临床应用的药物对胆管癌敏感性欠佳,而且存在明显毒副作用。因此,寻找更敏感、有效的药物,提高胆管癌药物治疗的疗效就变得十分必要。动物胆汁药具有活性强、疗效显著、副作用小等特点,在我国传统中药中有大量应用。近年来,动物胆汁的抗肿瘤作用备受关注,但是有关鳄鱼胆汁抗肿瘤活性的相关研究很少。 本论文以体外培养的人胆管癌QBC939细胞为药物筛选模型,从暹罗鳄胆汁中筛选获得具有抑制胆管癌细胞生长的活性物质,命名为鳄胆...Cholangiocarcinoma is a malignant biliary tract cancer originated from intrahepatic or extrahepatic biliary epithelium. The tumor often present at an advanced unresectable stage at the time of diagnosis for the majority patients, which eliminates the surgical approach as a curative measure. Thus, it is important to find out an effective therapeutic method excluded surgical. The response of cholang...学位:理学博士院系专业:生命科学学院生物化学与生物技术系_生物化学与分子生物学学号:2172008015042
