All individuals co-expressing psqKK111691 and EgfrUAS.cBa under the control of Scer\GAL4ap-md544 during larval stages (using Gal80[ts] for the temporal regulation of expression) are developmentally delayed and die at the third instar stage; their wing discs form epithelial tumors that exhibit cell polarity defects (i.e. Dlg mis-localization), associated with higher numbers of myoblasts and a more extensive/branched trachea than normal across the disc. The tumors metastasize to distant tissues in the larva.

The tumor phenotype (size and disc distortion) and the increased myoblast numbers are partially suppressed by the additional co-expression of either NrgHMS01638, capsID.UAS, SCARGD11380, or diaHM05027, but not of dsHMS00759, fjHMS01310 or ftHMS00932; diaHM05027 also partially suppresses the increased tracheation. There is no further tumor suppression by NrgHMS01638, diaHM05027 combined.

Co-expression of diadsRNA.lexAop under the control of Ecol\lexAGMR15B03 also partially suppresses the tumors and the increased myoblasts.

Co-expression of diaHM05027 under the control of Scer\GAL4ap-md544 also rescues most Scer\GAL4ap-md544>psqKK111691,EgfrUAS.cBa individuals to adulthood; the adults are fertile and their only visible phenotype is wing blade defects

Expression of psqKK111691 massively enhances the overproliferation seen in wing discs expressing EgfrScer\UAS.cBa under the control of Scer\GAL4ap-md544. The discs grow as multilayered masses. The larvae do not enter pupariation and the discs continue to grow, often filling the anterior half of the larva. The cells lose their apical-basal polarity and cells metastasise into internal organs including the gut and malpighian tubules. The basement membranes have degraded in these discs. Mutant epithelial cells are intermingled with wild type mesenchymal cells that resemble the adepithelial cells. Expression of psqKK111691 and EgfrScer\UAS.cBa specifically in the wing pouch under the control of Scer\GAL4nub.PU produces epithelial hyperplasia but no tumors. The proliferation of both the epithelial and mesenchymal cells in the tumor is rapid, with most of the mesenchymal proliferation taking place close to the epithelial layer.

Expression of dppJF01371 partially suppresses the growth of the massive wing disc tumors seen when EgfrScer\UAS.cBa and psqKK111691 are expressed under the control of Scer\GAL4ap-md544.

Expression of wgGD5007 partially suppresses the growth of the massive wing disc tumors seen when EgfrScer\UAS.cBa and psqKK111691 are expressed under the control of Scer\GAL4ap-md544.

Expression of trolGL01153 suppresses the growth of the massive wing disc tumors seen when EgfrScer\UAS.cBa and psqKK111691 are expressed under the control of Scer\GAL4ap-md544. Apicobasal polarity and tissue organisation is restored to the epithelial cells.

Expression of trolKK105502 suppresses the growth of the massive wing disc tumors seen when EgfrScer\UAS.cBa and psqKK111691 are expressed under the control of Scer\GAL4ap-md544. Apicobasal polarity and tissue organisation is restored to the epithelial cells.

Ablating adepithelial cells through expression of rprEcol\lexAop.cHa under the control of Ecol\lexAGMR15B03 suppresses the neoplastic transformation seen when psqKK111691 and EgfrScer\UAS.cBa are co-expressed under the control of Scer\GAL4ap-md544.

Expression of panΔN.Scer\UAS suppresses the growth of the massive wing disc tumors seen when EgfrScer\UAS.cBa and psqKK111691 are expressed under the control of Scer\GAL4ap-md544. Apicobasal polarity and tissue organisation is restored to the epithelial cells.

Expression of MadKK109050 does not suppress the growth of the massive wing disc tumors seen when EgfrScer\UAS.cBa and psqKK111691 are expressed under the control of Scer\GAL4ap-md544. Apicobasal polarity and tissue organisation is restored to the epithelial cells.

Expression of MaddsRNA.IVS.13xEcol\lexAop in adepithelial cells under the control of Ecol\lexAGMR15B03 suppresses the neoplastic transformation seen when psqKK111691 and EgfrScer\UAS.cBa are co-expressed under the control of Scer\GAL4ap-md544.
