Dobutamine has been widely used for the treatment of heart failure and
cardiogenic shock since the 1970s. Osteosarcoma is the most commonly observed
malignant bone tumor in children. Currently, there are no effective drugs for the
treatment of osteosarcoma. In the present study, the potential anticancer
activity of dobutamine on human osteosarcoma cells was examined. Human
osteosarcoma MG-63 cells were treated with dobutamine at various concentrations
and for various incubation times. The inhibition of cell growth by dobutamine was
determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay.
Flow cytometry was utilized to evaluate the effect of dobutamine on cell
apoptosis and the cell cycle. Furthermore, the expression levels of caspase-3 and
caspase-9 were assessed by western blot analysis. The influence of dobutamine on
cancer cell migration and invasion was additionally evaluated using wound-healing
assay and the Boyden Chamber migration method. Dobutamine significantly inhibited
the growth of MG-63 cells at a concentration of 10 µM or higher when incubated
for 12 h or longer (P=0.023). Dobutamine augmented cell apoptosis and arrested
the cell cycle in the G2/M phase. Western blot analysis revealed that dobutamine
induces expression of caspase-3 and caspase-9. In addition, the invasiveness and
migration of MG-63 cells was inhibited by dobutamine in a concentration-dependent
manner. The results of the present study may lead to novel applications for
dobutamine in the treatment of osteosarcoma.
