Effect of sodium quercetin monosulfate on the growth of HL-60 cells

The effect of sodium quercetin monosulfate (SQMS) on the growth of HL- 60 cells was studied by observing cytotoxicity, cell cycle progression, cytosolic free calcium level (［Ca²⁺］_i) and the activity of protein kinase CK2 of HL-60 cells. SQMS (20-120 μmol·L^-1) inhibited the growth of HL-60 cells in a concentration-dependent manner, arrested HL-60 cells in G₀/G₁ phase, increased the ［Ca²⁺］_i at 25-100 μmol·L^-1 from (105±9) to (201±13)nmol·L^-1, SQMS at 0.55-8.8 μmol·L^-1 inhibited the activity of CK2 purified from HL-60 cells in a concentration- dependent manner. These results indicated that SQMS inhibited the growth of HL-60 cells, which may be due to its inhibition of the activity of CK2，the increase in ［Ca²⁺］_i and inducing the differentiation of HL-60 cells.
