      Detailed Description
      Statement
      Reference

      Adults expressing Hsap\ATXN3Q80.HNHH.UAS under the control of Scer\GAL4elav.PU show a significant decrease in lifespan and a significant, age-dependent decline in climbing ability (observed in 4 weeks old adults but not in 1-3 weeks old adults), as compared to controls. Adulthood-only expression controlled by Scer\GAL4elav.Switch.PO (and RU486 feeding) also induces a decrease in lifespan but does not induce any consistent change in climbing ability.

      Scer\GAL4GMR.long-driven expression does not induce any obvious eye degeneration.
