Expression of auxGD7187 (together with UAS-Dicer2 to enhance RNAi efficiency) under the control of either Scer\GAL4ple.PU or Scer\GAL4Ddc.PU leads to age-progressive decline of the adult locomotor (climbing) abilities as well as shorter adult lifespan compared to controls. Additionally, expression under either of these drivers also results in age-dependent loss of dopaminergic neurons from the PPM1/2 cluster in the brain of aged (33 days old) but not young (3 days old) adult flies; with the Scer\GAL4ple.PU driver the flies also display a moderate decrease in the number of PPM3 neurons regardless of age and with the Scer\GAL4Ddc.PU driver aged flies display loss of PPL1 neurons too. Expression driven by the Scer\GAL4GMR58E02 driver has no evident effect on the number of dopaminergic neurons from the PAM cluster (regardless of age).

Adults expressing auxGD7187 under the control of Scer\GAL4elav.PLu (in the presence of Dcr-2Scer\UAS.cDa to increase the efficiency of RNAi) do not show a significant defect in avoidance of noxious temperature (46[o]C) compared to control flies.

Reference

The loss of dopaminergic PPM1/2 neurons observed even in very young adult flies expressing Hsap\SNCAA30P.Scer\UAS.cUa under the control of Scer\GAL4Ddc.PU is exacerbated further by co-expression of auxGD7187 and the number of neurons is further decreased. Simultaneous expression of the two transgenes driven by Scer\GAL4ple.PU also leads to early-onset loss of PPM1/2, which is otherwise not observed in young (3 or 10 days old) flies expressing either of the transgenes alone with this driver. This is not due to loss of these neurons during development as their number is comparable to controls in third instar larvae as well as 1 day post-eclosion adults co-expressing Hsap\SNCAA30P.Scer\UAS.cUa and auxGD7187 (with Scer\GAL4ple.PU or Scer\GAL4Ddc.PU).

Co-expression of Hsap\SNCAScer\UAS.cUa (but not Hsap\SNCAA53T.Scer\UAS.cUa) with auxGD7187 leads to significant decrease in the number of dopaminergic PPM1/2 neurons in the brains of young (3 and/or 10 days old) adult flies, which is not observed at this age when any of the transgenes is expressed alone.

Complementation and Rescue Data
Comments

The age-progressive rapid deterioration in adult locomotion (climbing ability) as well as the decreased adult lifespan characteristic for flies expressing auxGD7187 (together with UAS-Dicer2 to enhance RNAi efficiency) under the control of either Scer\GAL4ple.PU or Scer\GAL4Ddc.PU can be rescued by co-expression of auxFL.Scer\UAS.T:Avic\GFP.
