Figure 9From: Tumor necrosis factor-alpha induced expression of matrix metalloproteinase-9 through p21-activated Kinase-1IL-1 stimulation of PAK1 phosphorylation by primary rat hepatic stellate cells. Primary rat hepatic stellate cells were stimulated by IL-1α for the indicated time. Phosphorylation of PAK1 at threonine 423 and threonine-212 and GAPDH were measured by Western blot analysis.Back to article page
