    • Treatment of melanoma is achieved through reduction in the effective amount of clusterin in melanoma cells of in a mammalian subject, preferably a human. A therapeutic agent effective to reduce the effective amount of clusterin in the melanoma cells is administered to the subject. The therapeutic agent may be, for example, an antisense ODN or small inhibitory RNA (siRNA) compound targeted to clusterin. bcl-xL in a subject or cell line can also be regulated by administering to the subject or cell line an agent effective to modulate the amount of clusterin expression. In particular, in clusterin expressing cells, the expression of bcl-xL is down-regulated when the effective amount of clusterin is reduced. Such inhibition is significant because bcl-xL is known to act as an inhibitor of apoptosis.
    • 黑素瘤的治疗通过在哺乳动物受试者,优选人中减少黑素瘤细胞中的聚集蛋白的有效量来实现。 向受试者施用有效降低黑素瘤细胞中的聚集蛋白有效量的治疗剂。 治疗剂可以是例如靶向簇蛋白的反义ODN或小的抑制性RNA(siRNA)化合物。 受试者或细胞系中的bcl-xL也可以通过向受试者或细胞系施用有效调节聚集蛋白表达量的试剂来调节。 特别地,在簇蛋白表达细胞中,当有效量的聚集蛋白降低时,bcl-xL的表达下调。 这种抑制是显着的,因为已知bcl-xL作为凋亡抑制剂。

    • Agents that reduce the amount of IGFBP-2 and/or IGFBP-5 and that are known to be useful in the treatment of cancer result in increased expression of the protein clusterin. Since clusterin can provide protection against apoptosis, this secondary effect detracts from the efficacy of the therapeutic agent. In overcoming this, the present invention provides a combination of therapeutic agents that is useful in the treatment of cancer. The combination includes an agent that reduces the amount of IGFBP-2 and/or IGFBP-5 and that stimulates expression of clusterin as a secondary effect, and an oligonucleotide that is effective to reduce the amount of clusterin in cancer cells. In some embodiments of the invention, the agent that reduces IGFBP-2 and/or IGFBP-5 is a bispecific antisense species. The oligonucleotide may be an antisense oligonucleotide or an RNAi oligonucleotide.
    • 降低IGFBP-2和/或IGFBP-5的量并且已知可用于治疗癌症的药物导致蛋白质簇的表达增加。 由于簇蛋白可以提供针对细胞凋亡的保护作用,所以这种二次效应会降低治疗剂的功效。 克服这一点,本发明提供了可用于治疗癌症的治疗剂的组合。 该组合包括减少IGFBP-2和/或IGFBP-5的量并刺激簇蛋白表达作为次要作用的试剂,以及有效降低癌细胞中的簇蛋白的量的寡核苷酸。 在本发明的一些实施方案中,减少IGFBP-2和/或IGFBP-5的药剂是双特异性反义物质。 寡核苷酸可以是反义寡核苷酸或RNAi寡核苷酸。
