BACKGROUND/AIM: Hepatocyte growth factor (HGF) acts as a key regulator in promoting ovarian cancer metastasis. Previously, we observed that YYB-101, a humanized anti-HGF antibody, effectively inhibits ovarian cancer cell migration, invasion, and progression. Here, we evaluated the signaling mechanisms affected by YYB-101 that are important in ovarian cancer cell progression.
Using cell migration, invasion and proliferation assays, we evaluated the effects of YYB-101 on A2780/luc and SKOV3 cells. The effects of YYB-101 on signaling molecules were determined by immunocytochemistry and immunoblot analysis.
YYB-101 inhibited HGF-induced ovarian cancer cell motility by down-regulating paxillin phosphorylation and actin-cytoskeleton rearrangement. Also, YYB-101 inhibited ovarian cancer cell proliferation by reducing c-MET phosphorylation and activating apoptosis in vitro and in vivo. These effects were significantly enhanced by combining YYB-101 treatment with paclitaxel, a standard chemotherapy drug.
YYB-101 can be examined as a new therapeutic agent for the treatment of patients with ovarian cancer.
背景/目的:肝细胞生长因子(HGF)作为一种关键调节因子,促进卵巢癌转移。此前,我们观察到,一种人源化抗 HGF 抗体 YYB-101,能有效抑制卵巢癌细胞迁移、侵袭和进展。在此,我们评估了 YYB-101 影响卵巢癌细胞进展的重要信号通路机制。
采用细胞迁移、侵袭和增殖实验,评估 YYB-101 对 A2780/luc 和 SKOV3 细胞的影响。通过免疫细胞化学和免疫印迹分析,确定 YYB-101 对信号分子的影响。
YYB-101 通过下调整联蛋白相关蛋白磷酸化和肌动蛋白细胞骨架重排,抑制 HGF 诱导的卵巢癌细胞迁移。此外,YYB-101 通过减少 c-MET 磷酸化和体外及体内激活细胞凋亡,抑制卵巢癌细胞增殖。YYB-101 联合紫杉醇(一种标准化疗药物)治疗,这些作用显著增强。
YYB-101 可作为一种新的治疗卵巢癌患者的治疗药物进行研究。
