Abstract:
Objective To detect whether trichostatin(TSA) can induce HL-60 differentiation in vitro. Methods MTT method was used to test the effect of TSA on HL-60 cell growth. Cell cycle was tested by flow cytometry. CD11b expression was tested for detecting cell differentiation, RT-PCR was used to detect the mRNA expression of c-myc in the cells treated by TSA. Results Down-regulation of cell proliferation was observed and cells significantly accumulated at the G0 and G1 phase in HL-60 cells treated with TSA( P <0. 01). Dif-ferentiation rate was 15. 24% after being treated by TSA for 48 h. mRNA of c-myc was down regulated in time-dependent manner. Conclusion TSA can inhibit proliferation and induce differentiation in HL-60 cells.
