    • The c-Myc oncoprotein, a helix-loop-helix-leucine zipper (HLH-ZIP) transcription factor, is frequently deregulated in human cancers. All known functions of c-Myc, including those pertaining to transformation, require that it heterodimerize with another HLH-ZIP protein, Max. Using a high throughput yeast-based assay, we identified seven low molecular weight substances that inhibit c-Myc-Max association. Each compound also prevented this interaction in vitro and inhibited the growth of c-Myc-expressing fibroblasts, although not of fibroblasts lacking c-Myc. Finally, short-term exposure of c-Myc over expressing fibroblasts to several of the compounds markedly reduced their in vivo tumorigenicity. These studies suggest that yeast-based assays can be used to identify inhibitors of protein-protein interactions and that these frequently function in mammalian cells. The signature specificities of each of the c-Myc-Max compounds identified here further suggest synergistic in vivo function.
    • 螺旋 - 环 - 螺旋 - 亮氨酸拉链(HLH-ZIP)转录因子的c-Myc癌蛋白在人类癌症中经常被放松。 c-Myc的所有已知功能,包括与转化有关的功能,都要求其与另一种HLH-ZIP蛋白Max, 使用高通量的基于酵母的测定法,我们确定了七种抑制c-Myc-Max结合的低分子量物质。 每种化合物在体外也阻止了这种相互作用,并且抑制了表达c-Myc的成纤维细胞的生长,尽管不是缺乏c-Myc的成纤维细胞。 最后,c-Myc对几种化合物的表达成纤维细胞的短期暴露显着降低了其体内致瘤性。 这些研究表明,基于酵母的测定可用于鉴定蛋白质 - 蛋白质相互作用的抑制剂,并且这些测定在哺乳动物细胞中经常起作用。 此处鉴定的每种c-Myc-Max化合物的特征特征进一步表明协同的体内功能。
