4. SMU-B在体外能抑制外源性HGF诱导的人A549肺癌细胞的迁移和跨膜移动,具有抗肿瘤细胞的迁移和侵袭作用。 5. SMU-B在体外能显著抑制外源性HGF诱导的A549肺癌细胞c-Met、AKT及ERKl/2蛋白的磷酸化;也能在体外抑制GTL-16胃癌细胞和在体内抑制GTL-16胃癌裸鼠异体移植瘤的c-Met、AKT和ERK1/查找更多2蛋白的磷酸化,通过抑制c-Met信号通路发挥抗肿瘤作用。
伴随着血管生成而形成的肿瘤血液供应是实体瘤发生发展的关键步骤。普遍认为只有内皮细胞可以形成血管,但当内皮依赖的血管生成不能满足肿瘤的快速增殖时,一种重要的替代供血方式出现,即由肿瘤来源的非内皮细胞形成血管样网络—血管生成拟态(VasculogeniCP690550c mimicry, VM)。VM是部分肿瘤增殖早期获得供氧的主要途径,对肿瘤的生长和转移具有重要作用。目前仅有一项临床研究表明抗血管内皮生长因子受体2 (Vascular endothelial growth factor receptor 2, VEGFR2)拮抗剂改善胃癌(Gastric cancer,{Selleck Anti-infection Compound Library|Selleck Antiinfection Compound Library|Selleck Anti-infection Compound Library|Selleck Antiinfection Compound Library|selleck Anti-infection Compound Library|selleck Antiinfection Compound Library|selleck Anti-infection Compound Library|selleck Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|buy Anti-infection Compound Library|Anti-infection Compound Library半抑制浓度|Anti-infection Compound Library价格|Anti-infection Compound Library花费|Anti-infection Compound Library溶解度|Anti-infection Compound Library购买|Anti-infection Compound Library制造商|Anti-infection Compound Library查找购买|Anti-infection Compound Library订单|Anti-infection Compound Library mouse|Anti-infection Compound Library chemical structure|Anti-infection Compound Library分子量|Anti-infection Compound Library molecular weight|Anti-infection Compound Library数据表|Anti-infection Compound Library supplier|Anti-infection Compound Library体外|Anti-infection Compound Library细胞系|Anti-infection Compound Library concentration|Anti-infection Compound Library nmr|Anti-infection Compound Library体内|Anti-infection Compound Library clinical trial|Anti-infection Compound Library cell assay|Anti-infection Compound Library screening|Anti-infection Compound Library high throughput|buy Antiinfection Compound Library|Antiinfection Compound Library半抑制浓度|Antiinfection Compound Library价格|Antiinfection Compound Library花费|Antiinfection Compound Library溶解度|Antiinfection Compound Library购买|Antiinfection Compound Library制造商|Antiinfection Compound Library查找购买|Antiinfection Compound Library订单|Antiinfection Compound Library chemical structure|Antiinfection Compound Library数据表|Antiinfection Compound Library supplier|Antiinfection Compound Library体外|Antiinfection Compound Library细胞系|Antiinfection Compound Library concentration|Antiinfection Compound Library clinical trial|Antiinfection Compound Library cell assay|Antiinfection Compound Library screening|Antiinfection Compound Library high throughput|Anti-infection Compound high throughput screening| GC)患者预后,但其他多项研究均表明针对血管内皮的抗血管生成治疗药物(Bevacizuma环能完全解决肿瘤的治疗问题。应用抗VEGF治疗后,反而促进卵巢癌患者VM形成,提示当内皮依赖的血管生成被抑制时,VM可以作为一种重要的替代供血模式。大量临床与实验研究表明,黑色素瘤、卵巢癌、乳腺癌、肝癌、胃癌、胶质瘤等多种肿瘤中均存在VM;临床病理资料研究显示有VM的病人预后比无VM的病人预后差。
