The present disclosure, in part, is directed to a mammalian prostate cancer cell line comprising at least one or a set of primary mammalian epithelial cells which have been infected with a retroviral vector carrying an oncogene selected from the group consisting of c-Myc, Ha-Ras, NeuT, c-Src and combinations thereof and in which said gene is expressed. Applications of the pro-state cell lines, including immune competent animal models of prostate cancer, a method for the in vitro production of immortalized primary mammalian epithelial cells, a method of determining whether a human subject having prostate cancer is suffering from or at risk for developing metastasis, a method of preventing cancer or inhibiting metastasis of cancer susceptible to treatment in a subject at risk for developing cancer or metastasis of cancer, and method of identifying a candidate compound that selectively interferes with proliferation or viability of a cancer cell that has elevated levels of CCR5 and/or of at least one of its ligands.
本公开内容部分涉及一种哺乳动物前列腺癌细胞系,该细胞系由至少一种或一组原代哺乳动物上皮细胞组成,这些细胞已被携带选自 c-Myc、Ha-Ras、NeuT、c-Src 及其组合的癌基因的逆转录病毒载体感染,并且在其中表达了所述基因。原态细胞系的应用,包括前列腺癌的免疫能力动物模型、体外生产永生化原始哺乳动物上皮细胞的方法、确定患有前列腺癌的人类受试者是否患有转移或是否有发生转移风险的方法、一种在有罹患癌症或癌症转移风险的受试者中预防癌症或抑制易受治疗的癌症转移的方法,以及一种鉴定候选化合物的方法,该候选化合物可选择性地干扰CCR5和/或其至少一种配体水平升高的癌细胞的增殖或存活。
