Figure 5.

Relative luciferase activities in non-transfected or transfected HCT116 cells expressed as fold-activation relative to the control (without protein hydrolysates), and normalized to renilla. Different concentrations of PVH were added 12 h after transfection and cells were cultured for 24 h. A treatment with rosiglitazone (5 μM) was included for comparison. Data are the means of 12 independent experiments with their SD in bars. ^a,b,c,d Bars with different superscript letters indicate significant differences (p < 0.01) with respect to control with no rosiglitazone.
