Identifying mutant shapes and textures. In each case, four images of each sample were quantitatively analyzed and images were adjusted using Adobe Photoshop auto levels for display only. Scale bars = 15 μm. (a) The unusual cell shape induced by an RNAi reagent against Myo3A in human HT29 cells is quantitatively distinguishable from wild-type control cells. (b) The unusual cell shape induced by an RNAi reagent against PTPN21 in human HT29 cells is quantitatively distinguishable from wild-type control cells. (c) The unusual actin texture induced by an RNAi reagent against DUSP19 in human HT29 cells is quantitatively distinguishable from wild-type control cells. The images are pseudocolored to show the actin staining texture. The biological basis of these morphological changes and the specificity of the RNAi reagents remain to be determined.
