    • The present invention makes available assays and reagents for identifying anti-proliferative agents, such as mitotic and meiotic inhibitors. The present assay provides a simple and rapid screening test which relies on scoring for positive cellular proliferation as indicative of anti-mitotic or anti-meiotic activity, and comprises contacting a candidate agent with a cell which has an impaired cell-cycle checkpoint and measuring the level of proliferation in the presence and absence of the agent. The checkpoint impairment is such that it either causes premature progression of the cell through at least a portion of a cell-cycle or inhibition of normal progression of the cell through at least a portion of a cell-cycle, but can be off-set by the action of an agent which inhibits at least one regulatory protein of the cell-cycle in a manner which counter-balances the effect of the impairment.
    • 本发明提供用于鉴定抗增殖剂(如有丝分裂和减数分裂抑制剂)的测定和试剂。 本测定提供了一种简单快速的筛选试验,其依赖于阳性细胞增殖的评分作为抗有丝分裂或抗减数分裂活性的指示,并且包括使候选试剂与具有受损的细胞周期检查点的细胞接触并测量 药剂存在和不存在时的增殖水平。 检查点受损使得其通过细胞周期的至少一部分或者通过细胞周期的至少一部分抑制细胞的正常进展来导致细胞过早进展,但是可以通过 抑制细胞周期的至少一种调节蛋白的药物的作用,其以抵消该损伤的作用的方式。
