Inhibition of Anchorage-Independent Proliferation and G0/G1 Cell-Cycle Regulation in Human Colorectal Carcinoma Cells by 4,7-Dimethoxy-5-Methyl-l,3-Benzodioxole Isolated from the Fruiting Body of Antrodia camphorate

Dose effect of SY-1 on the concentrations of cell-cycle regulatory proteins. Normal human colonic epithelial (FHC, left panel) and cancer (COLO 205, right panel) cells were rendered quiescent for 24 h and then given 10% FCS in the presence or absence of SY-1 (75–150 μM) for an additional 15 h. Protein extracts (100 μg/lane) were separated by SDS-PAGE, probed with specific antibodies and detected using the nitro blue tetrazolium and 5-bromo-4-chloro-3-indolyl-phosphate systems. Membranes were also probed with an anti-GAPDH antibody to correct for differences in protein loading.
