    • Suppression of the Hepatocyte growth factor/scatter factor (HGF/SF)-Met signaling pathway by targeting the Met protein tyrosine kinase was tested as strategy for suppressing tumor growth. Using RNA interference (RNAi) technology and adenoviruses carrying siRNA (Ad Met siRNA) target sequences dramatically reduced Met expression in mouse, dog and human tumor cells. Met was suppressed using Ad Met siRNA in mouse mammary tumor (DA3) cells and Met-transformed (NIH3T3 (M114) cells as well as human prostate cancer, sarcoma, glioblastoma, gastric and ovarian cancer cells. Furthermore, the Ad Met siRNA infection reversed transformed cell morphology. Ad Met siRNA killed cancer cells by inducing apoptosis. RNAi targeting Met suppressed HGF/SF-mediated scattering as well as ligand-mediated invasion activity and growth of tumor cells. Met siRNA infection also abrogated downstream Met signaling to molecules such as Akt and p44/42 MAPK. Importantly, the Met siRNA triggered apoptosis was correlated to suppressed tumorigenicity in vivo. Intro-tumoral infection with c-met siRNA adenovirus vectors produced significant reduction in tumor growth. Thus Met RNAi is an effective weapon for targeting Met expression and for treating c-Met+ cancers.
    • 通过靶向Met蛋白酪氨酸激酶抑制肝细胞生长因子/分散因子(HGF / SF)-Met信号通路被测试作为抑制肿瘤生长的策略。 使用RNA干扰(RNAi)技术和携带siRNA(Ad Met siRNA)靶序列的腺病毒大大降低了小鼠,狗和人类肿瘤细胞中的Met表达。 Met在小鼠乳腺肿瘤(DA3)细胞和Met转化的(NIH3T3(M114)细胞以及人类前列腺癌,肉瘤,成胶质细胞瘤,胃癌和卵巢癌细胞中使用Ad Met siRNA进行抑制,此外,Ad Met siRNA感染逆转 Ad Met siRNA通过诱导凋亡来杀死癌细胞,RNAi靶向Met抑制HGF / SF介导的散射以及配体介导的侵袭活性和肿瘤细胞的生长Met siRNA感染也消除下游Met信号转导到分子,如 Akt和p44 / 42 MAPK。重要的是,Met siRNA引发的细胞凋亡与体内抑制的致瘤性相关,c-met siRNA腺病毒载体的肿瘤内感染导致肿瘤生长显着降低,因此Met RNAi是靶向Met的有效武器 表达和治疗c-Met +癌症。
