S3 Fig -

Western blots on (A) engineered HCC1806 and SUM159 cells with 0.5 μg/ml Dox-induced overexpression of MAPK4 (iMAPK4) or control (iCtrl) treated with MNK1/2 inhibitors SLV-2436 (2 μm), eFT-508 (1 μm), or DMSO control for 24 h and (B) WT and MAPK4-KO SUM159 and MDA-MB-231 cells treated with MNK1/2 inhibitors SLV-2436 (2 μm), eFT-508 (1 μm), or DMSO control for 24 h. Proliferation assays on (C) engineered HCC1806 and SUM159 cells with 0.5 μg/ml Dox-induced overexpression of MAPK4 (iMAPK4) or control (iCtrl) and (D) WT and MAPK4-KO MDA-MB-231 cells treated with MNK1/2 inhibitors SLV-2436 (2 μm), eFT-508 (1 μm), or DMSO control. Quantification data as means ± SD. Data are representative of at least 3 independent experiments. The numerical values underlying the figures can be found in S1 Data. (TIFF)
