Figure S1. Synergistic growth-inhibition between AZD1775 and olaparib in GC cells. After GC cells were treated with combination of AZD1775 and olaparib at a fixed ratio of 1:200 (AZD1775: olaparib) for 48 h, cell viability were measured by CCK-8 assays and Fa-CI plots were made using the Chou-Talalay method. CI < 1, =1 and > 1 indicated synergism, additivity, and antagonism, respectively. (TIF 206 kb
