Adults expressing Hsap\TARDBPUAS.cHa under the control of Scer\GAL4Toll-6-D42 show decreased climbing activity, as compared to controls.

Expression of Hsap\TARDBPScer\UAS.cHa driven by Scer\GAL4Appl.PU results in a decreased adult life span compared to controls. Expression under Scer\GAL4VGlut.PD causes defects in the neuromuscular junction (NMJ) morphology: reduced number of boutons, an increase in the proportion of small boutons, decrease in the NMJ area as well as in the length of the longest NMJ branch. When co-expressed with tkvScer\UAS.RD.T:Disc\RFP-mCherry a slight increase in the retrograde axonal transport and decreased stall duration of the mCherry-positive particles is observed along with their increased mobility over longer distances compared to controls. The mobility of Snx16-GFP particles (expressed using Snx16Scer\UAS.T:Avic\GFP) is however not affected. Expression of Hsap\TARDBPScer\UAS.cHa under the Scer\GAL4VGlut.PD driver also strongly inhibits larval crawling.

Hsap\TARDBPScer\UAS.cHa expression under the control of Scer\GAL4Toll-6-D42 or under the combined control of Scer\GAL4elav.Switch.PO and RU486 treatment leads to a reduction in adult lifespan, as compared to controls.

Motor neuron-directed expression of Hsap\TARDBPScer\UAS.cHa under the control of Scer\GAL4D42 leads to a rapid-onset paralysis with around 90% of flies succumbing between 3 and 4 weeks post-eclosion.

Flies expressing Scer\GAL4GMR.PU>Hsap\TARDBPScer\UAS.cHa exhibit depigmentation of the eye that increases with age. In these flies, the regular pattern of seven rhabdomeres seen in control flies is severely disrupted. The most severe cases display an almost complete loss of eye pigmentation and widespread necrosis.

2-3 weeks after eclosion flies expressing Hsap\TARDBPScer\UAS.cHa in motor neurons under the control of Scer\GAL4D42 display movement defects and ultimately paralysis, resulting in death within days of the onset of initial symptoms. The mutants survive approximately half as long as controls.

In addition of having reduced survival, Scer\GAL4D42>Hsap\TARDBPScer\UAS.cHa flies also exhibit eclosion defects. As well as complete eclosion failure, a number of flies die during eclosion with part of their body protruding from the pupal case. Some Scer\GAL4D42>Hsap\TARDBPScer\UAS.cHa flies have a shriveled wing phenotype.

The neuromuscular junction growth defects (reduced number of NMJ boutons, decreased NMJ area, length of the longest NMJ branch) as well as larval crawling defects characteristic for third instar larvae expressing Hsap\TARDBPScer\UAS.cHa under the control of Scer\GAL4VGlut.PD can be partially rescued by combination with Dadj1E4 in homozygous state. None of the NMJ growth aberrations can be restored by combination with just single copy of Dadj1E4, except the highly increased fraction of small boutons on the main NMJ axis (which is slightly increased also in Dadj1E4/+ larvae alone).

The neuromuscular junction growth defects characteristic for third instar larvae expressing Hsap\TARDBPScer\UAS.cHa under the control of Scer\GAL4VGlut.PD (reduced number of NMJ boutons, decreased NMJ area, length of the longest NMJ branch) as well as larval crawling defects and increased tkv-mCherry particle mobility (expressed using the tkvScer\UAS.RD.T:Disc\RFP-mCherry transgene) can be partially rescued by co-expression of Rab11N124I.Scer\UAS.

The reduced number of boutons on neuromuscular junctions as well as crawling defects observed in third instar larvae expressing Hsap\TARDBPScer\UAS.cHa under the Scer\GAL4VGlut.PD driver cannot be restored by either by simultaneous co-expression of Snx163A.Scer\UAS.T:Avic\GFP and tkvQ199D.Scer\UAS.T:Ivir\HA1. Co-expressing Rab5S43N.Scer\UAS also fails to restore the neuromuscular junction growth defects.

Heterozygous TBPHΔ142 causes a small increase in the lifespan of Scer\GAL4D42>Hsap\TARDBPScer\UAS.cHa flies.

stgEY12388 appears to extend the lifespan of a subset of Scer\GAL4D42>Hsap\TARDBPScer\UAS.cHa flies. Further analysis reveals that the lifespan extension is restricted to female flies.

Nup50KG09557 seems to preferentially increase maximum lifespan of Scer\GAL4D42>Hsap\TARDBPScer\UAS.cHa flies.

Itp-r83Aug3, Itp-r83Asv35 or Itp-r83A90B.0 each partially suppresses the climbing defect of 15-day old Scer\GAL4Toll-6-D42>Hsap\TARDBPScer\UAS.cHa flies. Itp-r83Aug3 or Itp-r83Asv35 also extend the median survival of Scer\GAL4Toll-6-D42>Hsap\TARDBPScer\UAS.cHa flies by 6.5 days or 5.5 days, respectively, but neither extends the lifespan of wild-type flies.

Flies co-expressing Hsap\UBQLN1Scer\UAS.cHa and Hsap\TARDBPScer\UAS.cHa both under the control of Scer\GAL4D42 show reduced survival as compared with Scer\GAL4D42>Hsap\TARDBPScer\UAS.cHa flies.

Flies co-expressing Hsap\UBQLN1Scer\UAS.cHa and Hsap\TARDBPScer\UAS.cHa both under the control of Scer\GAL4D42 have higher rates of wing malformation than the respected single Hsap\TARDBPScer\UAS.cHa-transgenic line.
