Description
In Drosophila, homozygosity for tumor suppressors, like lethal giant larvae, lgl, results in neoplastic transformation of imaginal disc epithelium - characterized by loss of their apico-basal polarity, unrestricted growth and invasion into neighboring tissues/organs. In genetic mosaics, however, lgl mutant clones are eliminated shortly after their initiation by cell competition. On the other hand, lgl mutant clones generated in Minute (M) genetic background, which compromises cell competition from the neighboring wild type cells, display clonal progression and tissue invasion. To gain insight into the molecular players of fly tumorigensis we undertook genome-wide transcriptional profiling of neoplastically transformed mosaic wing imaginal discs where lgl- clones were induced in M genetic background. Mosaic wing imaginal discs carrying wild type (lgl+) clones, also generated in M genetic background, served as controls. Transcriptional profile revealed up-regulation of a number of signaling pathways, such as Hippo, Wnt, TGF-beta or EGFR. Transcriptional profile of lgl- mosaic imaginal discs therefore provides a useful resource for identification of genes/pathways that are functionally relevant for carcinogenesis
