大多数患有卵巢癌的女性在诊断时已处于晚期,治疗选择很少。最近,单克隆抗体疗法的成功有限,因此需要更有效的抗体来改善长期生存。在本报告中,我们通过用人卵巢癌细胞系SKOV3免疫兔子,制备了多克隆兔抗卵巢癌抗体(Poly Ab)。 Poly Ab 与 SKOV3 结合并抑制癌细胞增殖。 Western blot分析表明,Poly Ab通过涉及caspase信号通路(包括caspase-3和caspase-9)的细胞凋亡来抑制癌细胞。最后,与对照抗体相比,在皮下和腹膜内异种移植小鼠模型中,施用Poly Ab分别达到64%和72%的肿瘤抑制作用。我们的研究结果表明,Poly Ab 是一种有效的细胞凋亡诱导剂,并且可能可用作卵巢癌治疗的安全抗癌剂。
Most women with ovarian cancer are diagnosed at an advanced stage and there are few therapeutic options. Recently, monoclonal antibody therapies have had limited success, thus more effective antibodies are needed to improve long-term survival. In this report, we prepared polyclonal rabbit anti-ovarian cancer antibody (Poly Ab) by immunizing rabbits with the human ovarian cancer cell line SKOV3. The Poly Ab bound to SKOV3 and inhibited the cancer cells proliferation. Western blot analysis was conducted, which indicated that Poly Ab inhibited cancer cells through apoptosis involving the caspase signaling pathway including caspase-3 and caspase-9. Finally, compared with the control antibody, administration of Poly Ab reached 64% and 72% tumor inhibition in the subcutaneous and intraperitoneal xenograft mouse model, respectively. Our findings suggest that Poly Ab is an effective agent for apoptosis induction and may be useful as a safe anticancer agent for ovarian cancer therapy.
