Brit J Cancer:类血管生成素蛋白3能够阻断FAK的细胞核输入并有助于索拉非尼响应

2018-08-01 AlexYang MedSci原创

索拉非尼不良的药物反应是一个重要的挑战。不良药物反应减少了肾细胞癌(RCC)患者的临床益处。因此,阐释恢复索拉非尼治疗响应的潜在机制具有中重要的意义。最近,有研究人员利用蛋白免疫印迹和免疫组化技术在2个RCC患者群体中测量了类血管生成素蛋白3(ANGPTL3)含量水平。在RCC细胞中,研究人员利用功能丧失和功能获得试验用来调查ANGPTL3在索拉非尼治疗中的生物学作用,还利用人类蛋白组芯片和免疫沉

索拉非尼不良的药物反应是一个重要的挑战。不良药物反应减少了肾细胞癌(RCC)患者的临床益处。因此,阐释恢复索拉非尼治疗响应的潜在机制具有中重要的意义。

最近,有研究人员利用蛋白免疫印迹和免疫组化技术在2个RCC患者群体中测量了类血管生成素蛋白3(ANGPTL3)含量水平。在RCC细胞中,研究人员利用功能丧失和功能获得试验用来调查ANGPTL3在索拉非尼治疗中的生物学作用,还利用人类蛋白组芯片和免疫沉淀试验探索ANGPTL3功能的相关分子机制。研究发现,在索拉非尼治疗的RCC中,ANGPTL3表达上调,且与良好的索拉非尼临床反应相关。ANGPTL3的敲除能够导致RCC细胞对索拉非尼产生耐受性。同时,ANGPTL3能够与粘着斑激酶(FAK)结合并且能够抑制索拉非尼诱导的FAK细胞核运输,从而导致p53泛素化的减弱,进一步导致细胞凋亡和增强索拉非尼响应。

最后,研究人员指出,在RCC患者中,ANGPTL3可能是索拉非尼治疗响应的一个新的预测因子,并且是提高其治疗作用的潜在靶标。
