摘要: 目的:通过制备多糖染料木素复合多糖(genistein combined polysaccharide,GCP)脂质体,分别从体内和体外实验评估GCP脂质体用于治疗前列腺癌潜在应用价值,促进纳米技术在前列腺癌化疗中的应用。方法:采用乙醇注入法制备GCP脂质体。通过细胞增殖检测和细胞周期分析技术以及建立前列腺癌荷瘤动物模型等,从体外和体内验证GCP脂质体抗肿瘤效果。结果:GCP脂质体增强了GCP对雄激素敏感的LNCaP细胞增殖的抑制作用,增强了GCP诱导雄激素敏感的LNCaP细胞的凋亡作用。同时,GCP脂质体增强了GCP对肿瘤小鼠肿瘤生长的抑制作用。结论:GCP脂质体相较于GCP,对雄性激素敏感的人类前列腺癌细胞有更好的抗肿瘤效果。

Abstract: AIM: To prepare genistein combined polysaccharide (GCP) liposomes and to evaluate the potential value of GCP liposomes for the treatment of prostate cancer by in vivo and in vitro experiments, and ultimately to promote the application of nanotechnology in prostate cancer chemotherapy. METHODS: GCP liposomes were prepared by ethanol injection. The anti-tumor effect of GCP liposomes was verified in vitro and in vivo by cell proliferation assay and cell cycle analysis, as well as establishing a tumor model of prostate cancer.RESULTS:GCP liposomes enhanced the inhibitory effect of GCP on androgen-sensitive LNCaP cell proliferation and the apoptosis of androgen-sensitive LNCaP cells induced by GCP. Also, GCP liposomes improved the inhibitory effect of GCP on tumor growth in tumor-bearing mice. CONCLUSION: GCP liposomes have better anti-tumor effect on androgen-sensitive human prostate cancer cells than GCP.
