a) Live cell morphology of HCT116 ARID1A WT, ARID1A+/−, and Arid1a−/− cells in culture;
b) Proliferation measured by MTT assay, error bars show standard deviation of 3 measurements (technical replicates);
c) Invasion measured by Matrigel-chamber based assay, error bars show standard deviation of 4 measurements (technical replicates);
d) Protein levels of ARID1A, E-Cadherin, and β-actin;
e) Protein levels of Vimentin and β-actin (Note: NIH 3T3 fibroblast cells included for positive control);
f) Fold change (log2) in SMARCA4 and SMARCC1 ChIP-Seq signals at SWI/SNF binding sites in Arid1a−/− cells relative to WT;
g) Immunoprecipitation of SWI/SNF complexes using antibodies targeting ARID1A and ARID1B;
h) Protein levels of ARID1B and β-actin following ARID1B knockdown with 3 independent shRNAs;
i) Proliferation following shRNA-mediated ARID1B knockdown measured by MTT assay; error bars show standard deviation of 3 measurements (technical replicates).
