Figure 4From: Glycine tomentella Hayata inhibits IL-1β and IL-6 production, inhibits MMP-9 activity, and enhances RAW264.7 macrophage clearance of apoptotic cellsGTH modulates the activity of matrix metalloproteinase. RAW264.7 cells were incubated with different concentrations of GTH for 24 hrs, followed by stimulation with LPS. The activity of (A) MMP-9 and (B) MMP-2 was analyzed by gelatin zymography after 12-hr LPS stimulation. Values represent mean ± SEM (n = 3, ** = P < 0.001 compared with LPS alone).Back to article page
