Transformed A431 keratinocytes were treated with control (siCT) or desmoplakin(siDP) siRNAs and the Rac inhibitor EHT1864 or the p38 MAPK inhibitorMT4, as indicated. Cells were subsequently plated onto fibronectin coated slidesand stained with phalloidin (red), DAPI (blue), and anti-paxillin (green) tovisualize actin filaments, nuclei, and focal adhesions, respectively, viaimmunofluorescence microscopy.
