UASt regulatory sequences drive expression of Hsap\TARDBP carrying the amino acid replacement D169G (a mutation identified in a single sporadic ALS patient).
The D169G mutation was identified in only one patient with sporadic ALS; the line with this mutation in flies rescues phenotypes similar to wild type protein.
Expression of Hsap\TARDBPD169G.Scer\UAS.cVBa driven by Scer\GAL4GMR.PU does not induce a rough eye phenotype and expression driven by Scer\GAL4nSyb.PU or Scer\GAL4elav-C155 does not cause wing expansion defects. With expression driven by Scer\GAL4nSyb.PU, there is a significant decrease in the number Kenyon cells in 3 (but not 50) day old flies, compared to controls; there are no changes in the length or thickness of the alpha and beta lobes in 3 or 50 day old flies, compared to controls. Expression driven by Scer\GAL4CCAP.PP results in predominantly nuclear localization of the protein, comparable with wild type.
Scer\GAL4nSyb.PU/Hsap\TARDBPD169G.UAS.cVBa is a suppressor | partially of lethal - all die before end of P-stage phenotype of TBPHΔ142/TBPHΔ23
Scer\GAL4nSyb.PU/Hsap\TARDBPD169G.UAS.cVBa is a suppressor of decreased cell number phenotype of TBPHΔ142/TBPHΔ23
Hsap\TARDBPD169G.UAS.cVBa, Scer\GAL4CCAP.PP is a suppressor of decreased cell number phenotype of Scer\GAL4CCAP.PP, TBPHKK108354
Scer\GAL4nSyb.PU/Hsap\TARDBPD169G.UAS.cVBa is a suppressor of adult CCAP neuron phenotype of TBPHΔ142/TBPHΔ23
Hsap\TARDBPD169G.UAS.cVBa, Scer\GAL4CCAP.PP is a suppressor of adult CCAP neuron phenotype of Scer\GAL4CCAP.PP, TBPHKK108354
Expression of Hsap\TARDBPD169G.Scer\UAS.cVBa driven by Scer\GAL4nSyb.PU partially rescues pupal lethality (around 50% of flies expected by a full rescue eclose) and suppresses the loss of bursicon neurons in TBPHΔ142/TBPHΔ23 or Scer\GAL4nSyb.PU>TBPHKK108354 mutants. However, the median lifespan of surviving TBPHΔ142/TBPHΔ23 flies with expression of Hsap\TARDBPD169G.Scer\UAS.cVBa is shorter than in controls.
