      Reference

      The expression of Hsap\GBAN370S.UAS.Tag:MYC,Tag:polyHis under the control of Scer\GAL4Ddc.PL leads to a progressive decrease in the number of adult dopaminergic neurons (total neurons and PPL1, PPM1/2 and PPM3 cluster neurons), as it is observed at day 22, but not at days 2 and 12, post eclosion, as compared to controls.

      (Maor et al., 2016)

      Scer\GAL4da.G32-mediated expression of Hsap\GBAL444P.Scer\UAS.T:Hsap\MYC,T:Zzzz\His6 results in significantly decreased survival from L3 larva to pupa and again from pupa to adult, compared to expression of Hsap\GBAScer\UAS.T:Hsap\MYC,T:Zzzz\His6.

      Scer\GAL4Ddc.PL-mediated expression of Hsap\GBAL444P.Scer\UAS.T:Hsap\MYC,T:Zzzz\His6 results in significant locomotion dysfunction (measured in a climbing assay) at 22 days of age, compared to expression of Hsap\GBAScer\UAS.T:Hsap\MYC,T:Zzzz\His6.
