An in vitro screening method for identifying a compound that modulates ER&bgr;-mediated cell growth inhibition is disclosed. The method includes: providing a mammalian test cell containing a functional ER&bgr; protein; contacting the test cell with a candidate compound; and detecting an increase or decrease in the expression of an ER&bgr;-regulated gene in the presence of the candidate compound. Compounds that modulate ER&bgr;-mediated cell growth inhibition can promote or inhibit this process. In some embodiments, the test cell contains no detectable ER&agr; protein. The ER&bgr;-regulated gene can be, e.g., the genes encoding receptor-like tyrosine kinase (RYK), 5-hydroxytryptamine A1 receptor (E2c), BCL-2 related A1, embryonic growth/differentiation factor, IL-12, TL1309, or IFN-&agr;/&bgr; receptor.
本发明公开了一种体外筛选方法,用于鉴定可调节ER&bgr;介导的细胞生长抑制的化合物。该方法包括:提供含有功能性ER&bgr蛋白的哺乳动物试验细胞;将试验细胞与候选化合物接触;检测候选化合物存在时ER&bgr调控基因表达的增加或减少。调节ER&bgr;介导的细胞生长抑制的化合物可以促进或抑制这一过程。在某些实施方案中,测试细胞不含可检测到的 ER&agr; 蛋白质。受ER&bgr;调控的基因可以是,例如,编码受体样酪氨酸激酶(RYK)、5-羟色胺A1受体(E2c)、BCL-2相关A1、胚胎生长/分化因子、IL-12、TL1309或IFN-&agr;/&bgr;受体的基因。
