UASt regulatory sequences drive expression of a 500bp inverted repeat.
Expression of cmetNIG.6392R and BacA\p35Scer\UAS.cUa in the dorsal compartment of the wing disc, under the control of Scer\GAL4ap.PU, results in a high percentage of cells with DNA content higher than 4n (up to 30%) when compared to control cells. This is accompanied by some tissue overgrowth. The resulting wing primordia are massively overgrown, and the cell population subjected to genetically induced CIN invade the neighboring wild-type territory. Larvae continue growing for longer than BacA\p35Scer\UAS.cUa-expressing control larvae and ultimately die.
