Fig. 5From: Extracts from Sageretia thea reduce cell viability through inducing cyclin D1 proteasomal degradation and HO-1 expression in human colorectal cancer cellsSTL and STB increase HO-1 expression. a SW480 cells were treated with STL and STB for 24 h. b SW480 cells were treated with STL and STB for the indicated times. c SW480 cells were treated with ZnPP (1 μM) for 2 h and then co-treated with STL and STB for the additional 24 h. Actin was used as loading control. *P < 0.05 compared to the cells without STL and STBBack to article page
