Changes of pro–IL-1 β protein level detected by Western blot in the cells of FLS. Western blot analysis detected expected size protein band of pro–IL-1β (A). The pro–IL-1β protein levels in different groups were expressed as a ratio to that of corresponding GAPDH (B). Data presented are mean ± S.E.M. Data were three independent experiments. *represents P < 0.05 in comparison with control during statistical analysis.
