Cell cycle modulation by vitamin D3compounds.
HL-60 cells were cultured for 4 days with either 1,25(OH)2D3 (10−7 M) or Gemini-19-nor (10−7 M), fixed, and stained with PI, and the cell cycle status was analyzed using flow cytometry. Column indicates mean (± SD) of 3 independent experiments. *P < .05 as determined by Student t test difference compared with the control group.
