Figure Lengend Snippet: FPF treatment inhibited proinflammatory protein expression and AP-1 and STAT3 activation in the CIA mouse model. C57BL/6 mice were injected intradermally with CII at the base of the tail on day 0 and then challenged with 50 μ g CII subplantar at both hind limbs on day 18. On day 46, the paws and the spleen were dissected and total proteins were extracted ( n = 3-4 each group). Expressions of phosphorylated (p-) Jun D+c-Jun (a) and p-STAT3 (b) in paws and MCP-1 in the spleen (c) were determined using western blot and quantified by densitometric analyses. All data are mean ± standard error of the mean (SEM). ∗ P < 0.05 and ∗∗ P < 0.01 vs. the vehicle-treated control as determined using Student's t -test.
