Figure 2From: Genes Associated With Prognosis After Surgery For Malignant Pleural Mesothelioma Promote Tumor Cell Survival In Vitro Phenotypic analysis of ARHGDIA knockdown cell lines. Tumor cells were transiently transfected with siRNAs targeting either ARHGDIA (top panels) or non-specific siRNAs (bottom panel, "Neg"). Cells were fixed and fluorescently labeled 72 hours later using primary antibodies to alpha-tubulin ("Tubulin") to show cellular morphology only, phospho-histone H3 ("pHH3") to mitosis, or cleaved lamin A to detect apoptosis. Nuclei were visualized using Hoechst stain. No obvious differences were observed in the numbers of pHH3-labeled cells in knockdown cells relative to negative control (based on total cell number) while the number of cleaved lamin A-positive cells were clearly increased in knockdown cells relative to negative control.Back to article page
