Total Flavonoids of Rhizoma Drynariae Restore the MMP/TIMP Balance in Models of Osteoarthritis by Inhibiting the Activation of the NF- and PI3K/AKT Pathways

Figure 5

The viability of SW1353 cells after treatment with different concentrations of total flavonoids of Rhizoma Drynariae (TFRD) and 10 ng/mL IL-1β. (a) SW1353 cells were treated with different concentrations of TFRD alone for 12 h. (b) SW1353 cells were treated with different concentrations of TFRD with or without 10 ng/mL IL-1β for 12 h. The data are derived from six independent experiments and expressed as the mean ± standard deviation ( < 0.05: cell viability increased compared with the control group; ^# < 0.05: cell viability decreased compared with the control group).
