查询词典 leukemia

Objective: To investigate the antitumor effects of Quercetin in P388 leukemia mice.

目的：研究槲皮素抗小鼠P388白血病的作用。

A human promyelocytic leukemia cell mutant (HL-60-AR) with deficiency in HGPRT and resistance to 8-AG was established by treat〓nt of the HL-60 cells with MNNG and prescreened in 0.3% agar RPMI-1640 semisolid medium containing 8-AG. The mutant cells show the following characteristics:(1) resistant to cytotoxic action of 8-AG and growing vigorously in medium containing 20ug/ml 8-AG;(2) capable of forming 〓〓 colonies in soft agar medium in the presenee of 8-AG:(3) highly sensitive to HAT selective medium and fail to growing in HAT medium of form colonies in soft agar medium containing HAT;(4) completely deficinet in HGPRT activity; and (5) no radioactive silver grains over the mutant cells due to the absence of -hypoxanthine incorporation showed by radioautography.

一、用MNNG诱变和8-AG进行抗性筛选，成功地建立了一株抗高浓度8-AG和完全缺失HGPRT活性的人早幼粒白血病细胞突变株(HL-60-AR)，该细胞能抵抗8-AG的毒性作用，对HAT选择培养基十分敏感，检测不到HGHRT活性，不能参入〓H一次黄嘌呤。
