Dobutamine inhibits SGC-7901 cell growth. A: Inhibition ratio (%) of dobutamine on the viability of SGC-7901 cells. Cells were treated with different concentrations of dobutamine (1, 3, 10 and 30 μmol/L) for 24, 48 and 72 h; B: Inhibition ratio (%) of dobutamine (30 μmol/L), cisplatin (8 μg/mL) and dobutamine (30 μmol/L) + cisplatin (8 μg/mL) for 24, 48 and 72 h on the viability of SGC-7901 cells. aP < 0.05 vs the combined group.
