The influence of CTX on SW1353 human chondrosarcoma cells. a Cell survival at various concentrations of CTX. The surviving cells were detected by an MTT assay. The relative density of surviving cells was normalized to the control group, which was set as 100 %. Four independent sets of experiments were performed. b Effects of CTX on MMPs and aggrecan gene expression in the cells. The gene expression of MMP-1, MMP-3, MMP-13 and aggrecan were examined by RT-PCR and agarose gel electrophoresis (left panel). The density of β-actin was used as the loading control. The results from IL-1β-induced cells were plotted, and CTX-treated results were normalized to the control (right panel). Data were expressed as the mean ± SE from three independent sets of experiments. **p < 0.01
