Medicarpin increases the ARE luciferase activity in HeLa cells. (A). Chemical structure of medicarpin. (B). The ARE-luciferase assay was performed in HeLa cells after treatment with indicated concentrations of medicarpin for 6 h. (C). The cytotoxic effect was measured by an MTT assay after treatment with different medicarpin concentrations of for 24 h. (D). The representative images of the HeLa cells were pictured after treatment with indicated concentrations of medicarpin for 24 h. The cell images were taken at the same magnification. Experiments were performed in triplicate and repeated three times with similar results. * p < 0.05; ** p < 0.001.
