The expression of p53Scer\UAS.Ex under the control of Scer\GAL4GMR.PU leads to a decrease in eye size, as compared to controls.

Expression of p53Scer\UAS.Ex in the eye under the control of Scer\GAL4GMR.PF induces vast cell death and produces small and rough eyes with fused ommatidia.

Scer\GAL4Ilp2.PR-mediated, but not Scer\GAL4Sgs3.PD-mediated expression results in delayed pupation and a significant reduction in pupal volume compared to controls.

Expression of p53Scer\UAS.Ex in the developing eye, under the control of Scer\GAL4GMR.PF, causes a partial ablation of the eye due to excessive cell death during eye development.

Expression of p53Scer\UAS.Ex under the control of Scer\GAL4GMR.PU results in a significant reduction in eye size and a disruption of ommatidial structure.

Scer\GAL4GMR.PU-mediated expression of p53Scer\UAS.Ex results in a disrupted adult eye, and increased apoptosis in the larval eye disc.

Expression of p53Scer\UAS.Ex under the control of Scer\GAL4insc-Mz1407 reduces neuroblast number by approximately 50%, compared to wild-type.

Overexpression of p53Scer\UAS.Ex in the developing eye under the control of Scer\GAL4GMR.PF generates a rough eye phenotype.

Expression of p53Scer\UAS.Ex under the control of Scer\GAL4hs.PU induces apoptosis in up to 18% of mitotically cycling imaginal disc cells, but not in any endocycling cells of salivary glands, fat body, or gut. Similar results are obtained in the ovary, where overexpression of p53 induces apoptosis in mitotically cycling but not endocycling follicle cells.

Expression of p53Scer\UAS.Ex under the control of Scer\GAL4ey.PH results in reduced eyes.

Expression of p53Scer\UAS.Ex under the control of Scer\GAL4GMR.PF does not affect eye pigmentation levels.

Flies expressing p53Scer\UAS.Ex under the control of Scer\GAL4GMR.PF have small eyes due to ectopic apoptosis.

Reference

The small eye phenotype resulting from the expression of p53Scer\UAS.Ex under the control of Scer\GAL4GMR.PU is not suppressed by heterozygosity for Glyatc02982 or by the co-expression of GlyatTH00482.

A Cdk7S164A.T170A mutant background significantly suppresses the partial eye ablation found upon expression of p53Scer\UAS.Ex in the developing eye, under the control of Scer\GAL4GMR.PF.

Co-expression of SetScer\UAS.cKa significantly suppresses the eye defects caused by expression of p53Scer\UAS.Ex under the control of Scer\GAL4GMR.PU.

Co-expression of Hr46RA.Scer\UAS or Hr46RB.Scer\UAS enhances the degenerative eye phenotype caused by Scer\GAL4GMR.PU-mediated expression of p53Scer\UAS.Ex.

Co-expression of Hr46RA.Scer\UAS or Hr46RB.Scer\UAS results in highly increased cell death in eye discs compared to Scer\GAL4GMR.PU-mediated expression of p53Scer\UAS.Ex alone.

Expression of p53Scer\UAS.Ex in numb15 mutant clones under the control of Scer\GAL4insc-Mz1407 effectively inhibits ectopic neuroblast formation.

Co-expression of p53Scer\UAS.Ex suppresses ectopic neuroblast formation induced by numbTS4D.Scer\UAS expression under the control of Scer\GAL4insc-Mz1407.

Larval brains expressing numbTS4D.Scer\UAS and p53Scer\UAS.Ex under the control of Scer\GAL4insc-Mz1407 exhibit an overall increase in apoptosis compared to controls (as visualised by TUNEL). However, neuroblast apoptosis remains rare, indicating that the apoptosis increase is in post-mitotic neurons or other brain cells.

A dapunspecified mutant background does not attenuate the ability of p53Scer\UAS.Ex expression to suppress the formation of ectopic neuroblasts induced by numbTS4D.Scer\UAS expression (under the control of Scer\GAL4insc-Mz1407).

Co-expression of agoΔF.Scer\UAS or CycEScer\UAS.cUa can partially suppress the neuroblast-loss phenotype induced by overexpression of p53Scer\UAS.Ex under the control of Scer\GAL4insc-Mz1407.

Co-expression of CycEScer\UAS.cUa and p53Scer\UAS.Ex generates a significant increase in ectopic neuroblasts in a numb15 mutant background, compared to overexpression of p53Scer\UAS.Ex alone in a numb15 mutant background.

The rough eye phenotype found at 29[o]C in flies expressing p53Scer\UAS.Ex under the control of Scer\GAL4GMR.PF is not affected by a Su(var)2-1003697, lwr05486, or smt3k06307 heterozygous background nor in a lwr05486-smt3k06307 transheterozygous background.

Co-expression of smt3Scer\UAS.cPa with p53Scer\UAS.Ex in the developing eye at 25[o]C or 29[o]C, under the control of Scer\GAL4GMR.PF does not affect the p53Scer\UAS.Ex-related rough eye phenotype.

The defective programmed cell death of the primordial germ cells (PGCs) see in out1 homozygous embryos is partially rescued by expression of p53Scer\UAS.Ex under the control of Scer\GAL4nos.UTR.T:Hsim\VP16.

Expression of p53Scer\UAS.Ex under the control of Scer\GAL4ey.PH does not enhance the L2/+ mutant phenotype of ventral eye loss.

The presence of p53Scer\UAS.Ex, under the control of Scer\GAL4GMR.PF does not affect the reduction in eye pigmentation observed in Ada2bd842 heterozygotes.

Co-expression of BacA\p35Scer\UAS.cHa does not affect the suppression of ectopic neuroblast formation by p53Scer\UAS.Ex in numbTS4D.Scer\UAS-expressing larval brains (all transgenes under the control of Scer\GAL4insc-Mz1407).

Co-expression of BacA\p35Scer\UAS.cHa does not affect the suppression of ectopic neuroblast formation by p53Scer\UAS.Ex (both transgenes under the control of Scer\GAL4insc-Mz1407) in numb15 mutant neuroblast clones.
