Fig. 5From: Combined targeting of MDM2 and CDK4 is synergistic in dedifferentiated liposarcomasIsobologram representation for the IB111, IB115, IB136 and IB114 cell lines. The dots located at the lower left, on the diagonal line, or at the upper right indicate synergism, additivity and antagonism, respectively. The combination index (CI) was calculated to be 0.37, 0.2, 1.36 and 1.78, respectivelyBack to article page
