UAS regulatory sequences drive expression of Hsap\TARDBP.
The expression of Hsap\TARDBPUAS.cIa under the control of Scer\GAL4GMR.PU leads to the thinning of the adult retina.
The expression of Hsap\TARDBPScer\UAS.cIa under the control of Scer\GAL4GMR.PU leads to eye morphology defects in 5 days old adults, including a significant decrease in retinal thickness, as compared to controls.
The eyes of 5-day old flies expressing one copy of Hsap\TARDBPScer\UAS.cIa under the control of Scer\GAL4GMR.PU exhibit a very mild disturbance in the ommatidial alignment and bristle polarity compared with controls. The retina shows marked disruption of the regularly ordered arrays of photoreceptor cells by a number of large vacuoles intervening the ommatidia, associated with disordered distribution of nuclei of photoreceptor cells.
When expression of one copy of Hsap\TARDBPScer\UAS.cIa under the control of Scer\GAL4GMR.PU is limited to the adult stages using Scer\GAL80ts.αTub84B no appreciable histological changes are observed in the retina at days 0 and 10, but scattered vacuolar degeneration is seen at day 30 and is exacerbated with age. The percentage of intact photoreceptors per retina also decreases with age. The phenotype is dose-dependent: more severe neurodegeneration is observed with two copies of Hsap\TARDBPScer\UAS.cIa.
Expression of Hsap\TARDBPScer\UAS.cIa in motor neurons under the control of Scer\GAL4D42 significantly shortens lifespan compared to controls.

The eye morphology defects and retinal thinning observed in 5 days old adults upon expression of Hsap\TARDBPScer\UAS.cIa under the control of Scer\GAL4GMR.PU are exacerbated by the co-expression of Hsap\PFN1C71G.Scer\UAS or Hsap\PFN1M114T.Scer\UAS, but not Hsap\PFN1Scer\UAS.cMa or chicNIG.9553R, and even leads to a severe rough eye phenotype and ommatidial fusion and misalignment, as compared to controls.
