Flies expressing Tip60Scer\UAS.cLa under the control of Scer\GAL4ey-OK107 show a significant reduction in total mushroom body size as compared to wild type. These flies also show a loss of mushroom body neuroadaptive response to environmental enrichment in the first 5 days of adulthood, in contrast to wild type flies, which exhibit an increase in mushroom body size when housed with other flies during the first 5 days of adulthood, versus those kept in isolation.
Scer\GAL4ey-OK107>Tip60Scer\UAS.cLa male flies show normal learning in a conditioned courtship suppression assay (placed with a mated female for 60 minutes), with a significant drop in the courtship index when comparing the first 10 minutes to the final 10 minutes (similar to wild type). Two minutes after training, flies are placed with a virgin female and courtship is assessed for 10 minutes: trained controls show significantly reduced courtship index when compared to sham (untrained males), whereas Scer\GAL4ey-OK107>Tip60Scer\UAS.cLa males show no significant drop (immediate-recall memory defect).
Mushroom bodies in Scer\GAL4ey-OK107>Tip60Scer\UAS.cLa third instar larvae or adults do not have significant morphological defects.
Expression of Tip60Scer\UAS.cLa under the control of Scer\GAL4P2.4.Pdf has no significant effect on the axonal pattern of the s-LNv neurons either in third instar larval or in adult brains. It has a weak effect on nighttime sleep in adults: the overall total amount of sleep is slightly decreased due to shorter sleep bout duration, daytime sleep is not affected.
Expression of Tip60Scer\UAS.cLa at 25[o]C from late embryonic development to adulthood, under the control of Scer\GAL4337Y does not affect viability or generate a noticeable phenotype.

Co-expression of Tip60Scer\UAS.cLa suppresses the mushroom body morphological defects, observed in flies expressing Hsap\APP695.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4ey-OK107. The mushroom body neuroadaptive response to environmental enrichment is also restored in these flies.
Co-expression of Tip60Scer\UAS.cLa (but not Tip60E431Q.Scer\UAS) suppresses learning and memory defects in Scer\GAL4ey-OK107>Hsap\APP695.Scer\UAS.T:Hsap\MYC males. Co-expression of Tip60Scer\UAS.cLa or Tip60E431Q.Scer\UAS does not affect learning but abolishes short-term memory of courtship suppression in Scer\GAL4ey-OK107>Hsap\APP695ΔCT.Scer\UAS.T:Hsap\MYC males.
Co-expression of Tip60Scer\UAS.cLa partially suppresses the locomotor defects and vesicle accumulation on motor axons that is seen in third instar larvae expressing Hsap\APP695.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4elav-C155.
Simultaneous expression of Tip60Scer\UAS.cLa with Hsap\APP695.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4P2.4.Pdf has no effect on the axonal pattern of the s-LNv neurons in third instar larval brain, while it leads to a large increase in the area of the s-LNv neuron axonal arbor in the adult brain and it also rescues the nighttime sleep defects observed in adult flies expressing either of the transgenes alone. Co-expression with Hsap\APP695ΔCT.Scer\UAS.T:Hsap\MYC has no significant effect on the axonal pattern of the s-LNv neurons either in larval or in adult brains and it does not rescue but rather enhance the nighttime sleep deficit observed in flies expressing Tip60Scer\UAS.cLa alone.
Co-expression of Tip60Scer\UAS.cLa rescues the locomotor behaviour defects seen in third instar larvae expressing Tip60E431Q.Scer\UAS under the control of Scer\GAL4elav-C155.
The loss of s-LNv terminal synaptic arborization and reduced axon length in the adult brain as well as the sleep defects characteristic for flies expressing Tip60E431Q.Scer\UAS under the control of Scer\GAL4P2.4.Pdf is rescued by co-expression of Tip60Scer\UAS.cLa.
Co-expression of Tip60Scer\UAS.cLa rescues the lethality associated with the expression of Tip60E431Q.Scer\UAS, when both transgenes are under the control of Scer\GAL4337Y.
