Figure 2: Cytotoxicity of 1,25(OH)2D3, (1,25(OH)2D3)L, 1,25(OH)2D3-3-BE or (1,25(OH)2D3-3-BE)L in PC cells. Cells were treated with ethanol (control), blank liposome (control), various doses of 1,25(OH)2D3, (1,25(OH)2D3)L, 1,25(OH)2D3-3-BE or (1,25(OH)2D3-3-BE)L for 16 hr followed by 3H-Thymidine incorporation assay by a procedure described in Materials and Methods section. There were six replicates for each sample. Statistics was done by student’s t test: ***p<0.001, **p<0.01. |
