Detailed Description

Statement

Reference

Expression of Egfr^{2.A887T.Scer\UAS} driven by Scer\GAL4^tin.CΔ4 results in a failure of flies to eclose from the late pupal stage.

(Yu et al., 2010)

Glial clones in adult brains expressing Egfr^{2.A887T.Scer\UAS} under the control of Scer\GAL4^repo.PU contain two-fold more cells than wild type.

Optic lobe clones expressing Egfr^{2.A887T.Scer\UAS} generated using eyFLP under the control of Scer\GAL4^repo.PU contain a modest number of excess and abnormal glia relative to wild type controls.

(Read et al., 2009)

When expression is driven by Scer\GAL4^32B extra vein tissue appears in the wing. Phenotype is more pronounced at elevated temperatures. When expression is driven by Scer\GAL4^h-H10 eyes show gaps in the array of ommatidia.

Additional Comments

Genetic Interactions

Statement

Reference

The high levels of apoptosis (detected by Caspase-3 staining) observed in Rbf^15aΔ;Stam¹⁹ double homozygous somatic MARCM clones in third instar larval eye disc is strongly suppressed by expression of Egfr^{2.A887T.Scer\UAS} under the control of the Scer\GAL4^Act.PU driver in the mutant clones.

(Sheng et al., 2016)

Expression of Egfr^{2.A887T.Scer\UAS} under the control of Scer\GAL4^btl.PS enhances the tracheal defects seen in Ptp10D¹ Ptp4E¹ double mutant embryos; the increase in diameter of the transverse connective/lateral trunk junction is further enhanced, and cysts appear on all dorsal branches.

(Jeon and Zinn, 2009)

Egfr^{2.A887T.Scer\UAS} Pten¹¹⁷ double mutant clones generated under the control of Scer\GAL4^repo.PU are overgrown and invasive. Cells from mutant clones appear to invade the brain, typically following fibre tracts, and sometimes inducing the formation of trachea. Mutant cells often penetrate deep into the brain. Smaller clones are commonly seen that are composed of relatively differentiated, enlarged glia with diffusely invasive projections.

Egfr^{2.A887T.Scer\UAS} Pten¹¹⁷ double mutant clones generated using eyFLP under the control of Scer\GAL4^repo.PU contain more excess glial cells than in either mutant alone. The clones are composed of 10s of glial cells in third instar larvae, becoming large invasive tumors composed of hundreds to thousands of cells in adults.
