EAC-B downregulated cell cycle related gene/protein (Cyclin D1) expression. MGC-803 cells were treated with or without 31 μg/mL of EAC-B for 4 h prior to RT-PCR (A) and western blotting (B) analysis. GADPH was housekeeping control. Left: representative immunoblot; Right: densitomentric analysis. n = 3, mean ± SD. c: p < 0.001, vs. control group.
