Fig. 2From: Combined treatment with inhibitors of ErbB Receptors and Hh signaling pathways is more effective than single treatment in reducing the growth of malignant mesothelioma both in vitro and in vivoInteraction between GANT and AFA, as assessed by the analysis of cell survival of MM cell lines, according to the method of Kern. The figure represents Kern Index (R) values for the two drugs combined at the indicated concentrations. R > 1 represents a synergistic effect, R = 1 indicates that the effect is additive, R < 1 indicates that the effect of the combined treatment is less than additiveBack to article page
