lexAop regulatory sequences drive expression of an inverted repeat targeting Mad.
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.
