Fig. (1) SAHA (A) as well as DAC (B) downregulated cell multiplication of KG-1 cells. KG-1 cells were seeded at a density of 300,000 cells/ml and cultured for 1, 2 and 3 days with the indicated concentrations. Thereafter cells were counted with a cell counter (Cazy, Germany). Bars represents mean ± SD (cells/ml); *P < 0.05; n=4.
