Ablation of mechanosensory chordotonal neurons via Scer\GAL4nan.PK-mediated expression of WScer\UAS.cYa eliminates the wind-induced suppression of locomotion response.
Flies carrying both WScer\UAS.cYa and Scer\GAL4GMR.ICD.T:Hsap\APP are viable but exhibit an almost complete absence of eye tissue, due to extensive apoptosis of the cells in the eye.

Co-expression of X11LGMR.cGa with WScer\UAS.cYa and Scer\GAL4GMR.ICD.T:Hsap\APP almost completely restores eye size to wild-type.
Co-expression of X11LΔPTB.GMR with WScer\UAS.cYa and Scer\GAL4GMR.ICD.T:Hsap\APP fails to restore eye size to wild-type.
Co-expression of Hsap\APBA2GMR.cGa with WScer\UAS.cYa and Scer\GAL4GMR.ICD.T:Hsap\APP almost completely restores eye size to wild-type.
'Undead' cells have been generated in the posterior of the wing disc by simultaneously activating and preventing cell death by coexpression of hidScer\UAS.cYa and BacA\p35Scer\UAS.cHa under the control of Scer\GAL4hh-Gal4. At 78 hours AEL these wing discs are similar in size, morphology and the pattern of BrdU incorporation to control discs. However, by 96 hours AEL the discs are significantly smaller than controls; the posterior cells and a subset of anterior cells are arrested in G2 and 'undead' posterior cells are nearly 1.73 larger than anterior cells. By the late wandering stage, the 'undead' posterior cells are similar in size to anterior cells, but their cell cycles have shifted to one similar to younger control wing discs, while arrest in anterior cells is permanent. Cell proliferation of the 'undead' cells continues into pupal development and these cells are unable to differentiate and eventually disintegrate.
Neither a tefuatm-6 or lokp6 mutant background can alleviate the overgrowth or anterior cell cycle arrest of wing discs with posterior 'undead' Scer\GAL4hh-Gal4>hidScer\UAS.cYa, BacA\p35Scer\UAS.cHa cells.
The cell cycle arrest and undergrowth phenotype of 96 hour wing discs with posterior 'undead' Scer\GAL4hh-Gal4>hidScer\UAS.cYa, BacA\p35Scer\UAS.cHa cells is completely alleviated in both p535A-1-4 and p53-ns backgrounds.
'Undead' Scer\GAL4en-e16E>hidScer\UAS.cYa, BacA\p35Scer\UAS.cHa cells in the posterior of the wing disc show no overgrowth phenotype in a DroncI29 background.
Cell proliferation is increased 2- to 4-fold in the posterior compartment of wing discs coexpressing BacA\p35Scer\UAS.cHa and hidScer\UAS.cYa under the control of Scer\GAL4en-e16E. In the adult, this gives rise to wings with an expansion of the posterior compartment associated with several extra tissue folds. The increased cell proliferation seen in the posterior compartment of wing discs and in adult wings coexpressing BacA\p35Scer\UAS.cHa and hidScer\UAS.cYa under the control of Scer\GAL4en-e16E is suppressed if they are also coexpressing DroncC318S.Scer\UAS.
