The effects of sonic hedgehog (Shh) and resveratrol (Res) on HCT116 cell viability

A: The effects of Shh on HCT116 cell viability. The cell viability significantly increased at the concentration (0.50, 1.0 µg/ml) on 24 hr B: The effects of Res on HCT116 cell viability stimulated by Shh. Res (50, 100 μM) obviously inhibited the cell viability stimulated by Shh Data are expressed as mean±SD. Six replicates for each group. #P<0.05, ##P<0.01 versus Control; *P<0.05, **P<0.01versus Shh group
