Interleukin-1 beta up-regulates tissue inhibitor of matrix metalloproteinase-1 mRNA and phosphorylation of c-jun N-terminal kinase and p38 in hepatic stellate cells

Figure 2 IL-1β activates JNK and p38 in a time-dependent manner in rat HSC. A: Representative Western blot results of JNK and p38; B: Densitometry of Western blot analyzed by Gel-Pro software. n=6. ^bP < 0.01 vs 0 h of JNK, ^aP < 0.05 vs 0 h of p38, ^dP < 0.01 vs 0 h of p38.
