Abstract Title: 

[Oridonin inhibits proliferation of Jurkat cells via the down-regulation of Brg1].


OBJECTIVE: To investigate the effect of oridonin on the human acute lymphocytic leukemia cell line Jurkat and its mechanism.METHODS: Jurkat cells were cultured in vitro and treated with various concentrations (0, 1.25, 2.5, 5, and 10 μmol/L) of oridonin for different lengths of time (24, 48, and 72 hours). The proliferation of Jurkat cells was analyzed by MTT assay. The changes in nuclear morphology were evaluated by fluorescence microscopy at 12 hours after treatment with various concentrations of oridonin. The expressionlevels of Brg1, P53, and C-myc were determined by semi-quantitative Western blot in Jurkat cells treated with various concentrations of oridonin for 24 hours or 5 μmol/L oridonin for various lengths of time (0, 2, 6, 12, and 24 hours). The expression levels of P53 and C-myc and proliferationof Jurkat cells were evaluated after Brg1 expression was knocked down by Brg1-specific siRNA.RESULTS: Compared with the control group, the proliferation of oridonin-treated Jurkat cells was significantly inhibited in a concentration- and time-dependent manner (P
