A) Cells were treated with vehicle, BRAFi, ERKi, or the combination and secreted FN1 was quantified using ELISA assays B) Indicated cells were treated with BRAFi, ERKi, FN1, or the indicated combinations for 24 hrs then plated in Matrigel-coated Boyden chambers for 24 hrs. Invading cells were stained with DAPI and counted using ImageJ or the Cytation 5 Cell Imaging Multi-Mode Reader. Results displayed as mean +/− SEM. *, p<0.05; **, p<0.01. BRAFi: 100 nM dabrafenib, ERKi: 1 μM SCH772984, FN1: 100 ng/ml fibronectin.
