Abstract Background In multicellular animals cell size is controlled by a limited set of conserved intracellular signaling pathways which when deregulated contribute to tumorigenesis by enabling cells to grow outside their usual niche. To delineate the pathways controlling this process we screened a genome-scale image-based Drosophila RNA interference dataset for double-stranded RNAs that reduce the average size of adherent S2R cells. Results Automated analysis of images from this RNA interference screen identified the receptor tyrosine kinase Pvr Ras pathway components and several novel genes as regulators of cell size. Significantly Pvr Ras signaling also affected the size of other Drosophila cell lines and of larval hemocytes. A .
