利用靶向性血栓药物对实体瘤血管的选择性栓塞是一种新颖的抗肿瘤策略。该策略以截短的组织因子(truncatedTissueFactor,tTF)为效应因子,结合肿瘤血管靶向载体实现选择性诱发肿瘤组织血管栓塞,阻断肿瘤营养物质和氧气的供给,引发肿瘤缺血性坏死,达到抗肿瘤作用。 这种策略需要靶向至肿瘤血管的载体。CREKA五肽能够特异性结合肿瘤血管中的凝血血浆蛋白,具有良好的肿瘤血管靶向作用,是一个理想的载体。我们通过构建CREKA与tTF融合蛋白来探讨这种融合蛋白是否能够选择性诱发肿瘤组织血管栓塞从而达到抗肿瘤作用。 首先运用生物信息学的方法对两者构成的融合蛋白进行分子模拟,从理论上选定最优的...It is a promising anti-tumor strategy to selectively shut down the blood vessels of tumors. This strategy use truncated Tissue Factor (tTF) as the effector, which combined with tumor vessels targeting carrier to selectively induce thrombosis in tumor vasculature and cut off the nutrition or oxygen supplies of tumor, subsequently result in necrosis of the tumor and obtained anti-tumor effects.
