Detailed Description
Statement
Reference

Flies expressing foxoGS9928 under the control of Scer\GAL4GMR.PF show a smaller eye with disrupted eye shape.

Overexpression of foxoGS9928, under the control of Scer\GAL4GMR.PF, produces distinctive ommatidial loss, particularly in the posteroventral part of the eye.

Expression of Akt1Scer\UAS.cSa in animals expressing foxoGS9928 under the control of Scer\GAL4GMR.PF completely suppresses the eye phenotype.

Expression of wdbGS9548 in animals expressing foxoGS9928 under the control of Scer\GAL4GMR.PF dramatically enhances the eye phenotype. This effect is completely suppressed by co-expression of Akt1Scer\UAS.cSa.

Expression of wdbEP3559 in animals expressing foxoGS9928 under the control of Scer\GAL4GMR.PF enhances the eye phenotype.

mts02496/+ has little effect on the eye phenotype of animals expressing foxoGS9928 under the control of Scer\GAL4GMR.PF.

mts02496/+ suppresses the eye phenotype of animals expressing wdbGS9548 and foxoGS9928 under the control of Scer\GAL4GMR.PF.

Expression of mtsDN.Scer\UAS in animals expressing foxoGS9928 under the control of Scer\GAL4GMR.PF completely suppresses the eye phenotype.

Co-expression of Akt1Scer\UAS.cSa suppresses the Scer\GAL4GMR.PF>foxoGS9928 phenotype.

Co-expression of the following transgenes with Scer\GAL4GMR.PF>foxoGS9928 results in an enhancement of the ommatidial phenotype: Pi3K92ED954A.Scer\UAS.T:Hsap\MYC, CG1139GS10666 and pathGS13857. Akt1Scer\UAS.cSa is able to express the combined effects of these transgenes so that eyes appear normal.

Co-expression of RhebAV4 with Scer\GAL4GMR.PF>foxoGS9928 leads to the loss of virtually all ommatidia in females. In contrast, males of this genotype suffer massive tissue degeneration in the head as late pupae and die at this stage.

Co-expression of S6kScer\UAS.cWa strongly enhances the Scer\GAL4GMR.PF>foxoGS9928 ommatidial phenotype.

Expression of TorWT.Scer\UAS.T:Zzzz\FLAG does not affect the Scer\GAL4GMR.PF>foxoGS9928 phenotype.

Co-expression of pathScer\UAS.cGa and TorWT.Scer\UAS.T:Zzzz\FLAG together enhance the Scer\GAL4GMR.PF>foxoGS9928 reduced eye phenotype.
