Risedronate suppressed the expressions of MMP-2 and MMP-9 mRNA in SaOS-2 and U2OS cells. (A) Cells were treated with the indicated concentrations of risedronate for 48 h and then processed for RT-PCR. Beta-actin was used as a loading control. Images are representative of three independent experiments. MMPs mRNA levers (expressed as percentages of controls) are shown in B (n = 3). Numbers in the box represent the concentration of risedronate in μM added to the cells. Bars represent MMPs mRNA levels (expressed as percentages of controls) of each band ± standard deviation.
