    • A method of identifying inhibitors of the anti-apoptotic survival pathway in cancer cells is disclosed. The method comprises the steps of (a) exposing cultured wild-type cells to a candidate inhibitor at a predetermined concentration for a predetermined period of time and determining cell viability after the exposure to the candidate inhibitor; (b) exposing two or more cell lines of specifically MCL-1 or BCL-2 or BCL-X L addicted cells to the candidate inhibitor at the predetermined concentration for the predetermined period of time and determining cell viability after the exposure to the candidate inhibitor; and (c) identifying the candidate inhibitor as a MCL-1 or BCL-2 or BCL-X L inhibitor if the cell viability in step (a) is significantly higher than the cell viability in step (b). The disclosed method provides a way to identify inhibitors which selectively inhibit specific members of the BCL-2 family ( e.g ., MCL-1) by screening two or more cell lines with addictions to different and specific members of the BCL-2 family of proteins.
    • 公开了一种鉴定癌细胞中抗凋亡存活途径抑制剂的方法。 该方法包括以下步骤:(a)将培养的野生型细胞暴露于预定浓度的候选抑制剂达预定时间段,并测定暴露于候选抑制剂后的细胞活力; (b)将特定MCL-1或BCL-2或BCL-XL嗜中性细胞的两种或更多种细胞系暴露于预定浓度的候选抑制剂达预定时间段并测定细胞活力 暴露于候选抑制剂后; 和(c)如果步骤(a)中的细胞活力显着高于步骤(b)中的细胞活力,则鉴定候选抑制剂为MCL-1或BCL-2或BCL-XL抑制剂 )。 所公开的方法提供了一种通过筛选两种或更多种细胞系选择性抑制BCL-2家族的特定成员(例如,MCL-1)的抑制剂的方法,所述细胞系对不同的和特定成员 BCL-2家族蛋白质。
