Synthetic Isoliquiritigenin Inhibits Human Tongue Squamous Carcinoma Cells through Its Antioxidant Mechanism

Figure 6

MMP-2 and MMP-9 activities in response to S-ISL: MMP-2 and MMP-9 proteolytic activities were measured in Tca8113 cells pretreated with S-ISL (6.25~100 μg/mL) at various concentrations for 24 h using Gelatin zymography assay. S-ISL: synthetic isoliquiritigenin; MMP: matrix metalloproteinase. Values are Mean (SD). , versus the vehicle group.
