Detailed Description

Expression of NmnatScer\UAS.cZa under the control of Scer\GAL4elav.PU has no effect on learning and memory in an aversive phototaxis assay at 20 days post eclosion. No locomotor activity defects are seen, as measured by climbing performance and brains do not display any morphological defects.

Overexpression of NmnatScer\UAS.cZa under the control of Scer\GAL4elav-C155 has no effect on dendrite outgrowth.

Expression of NmnatScer\UAS.cZa under the control of Scer\GAL4GMR.PF protects flies against neuronal degeneration in response to intense light exposure; eyes expressing this transgene show less vacuolization and a higher number of rhabdomeres than wild-type flies in response to 30 days of light exposure.

The anterograde mitochondria transport defects of single cell milt33-853 larval motor neuron clones are not rescued by expression of NmnatScer\UAS.cZa under the control of Scer\GAL4D42.

Expression of NmnatScer\UAS.cZa under the control of Scer\GAL4elav-C155 protects both wild-type and milt33-853 motor neuron clones from degeneration after axotomy at 16 hours after crushing.

Whereas wtsx1 ddaC MARCM clones show a simplifed dendritic arbor with significantly reduced numbers of terminal branches, wtsx1 clones overexpressing NmnatScer\UAS.cZa under the control of Scer\GAL4elav-C155 elaborate dendrites with terminal branch numbers that do not differ statistically from wild-type controls. A similar rescue is seen in class IV neurons.

Co-expression of NmnatScer\UAS.cZa suppresses the rhabdomere degeneration phenotype induced by Scer\GAL4GMR.PF>Atx-1Scer\UAS.cTa.

The loss of rhabdomere phenotype of rdgAunspecified mutants is significantly rescued by either NmnatScer\UAS.cZa or NmnatWR.Scer\UAS, under the control of Scer\GAL4GMR.PF. The size of vacuoles that are present in the retina and photoreceptors of rdgAunspecified mutants are reduced by expression of NmnatWR.Scer\UAS, but not NmnatScer\UAS.cZa.

The number of rhabdomeres per ommatidium is significantly rescued in trpP365 flies by expression of either NmnatScer\UAS.cZa or NmnatWR.Scer\UAS under the control of Scer\GAL4GMR.PF. However, the vacuolarization that occurs in trpP365 retinae and photoreceptors is not suppressed by either transgene.

Expression of NmnatScer\UAS.cZa suppresses the learning and memory deficits seen in 20 day old flies expressing Hsap\MAPTScer\UAS.cWa under the control of Scer\GAL4elav.PU. The climbing defects are suppressed to near wild type levels. The brain vacuolisation seen at 20 days post eclosion is almost completely suppressed.

Expression of NmnatScer\UAS.cZa suppresses the learning and memory deficits seen in 20 day old flies expressing Hsap\MAPTR406W.Scer\UAS under the control of Scer\GAL4elav.PU. The climbing defects are also suppressed to near wild type levels. The brain vacuolisation seen at 20 days post eclosion is almost completely suppressed and fewer apoptotic cells are seen in the midbrain.

The rough eye and rhabdomere phenotypes of Scer\GAL4GMR.PF>Hsap\ATXN182Q.Scer\UAS are partially suppressed by co-expression of NmnatScer\UAS.cZa.

Complementation and Rescue Data
Comments

Post-synaptic expression of NmnatScer\UAS.cZa under the control of Scer\GAL421-7 is sufficient to rescue the dendritic phenotypes observed in NmnatΔ4790-2 ddaC clones, demonstrating a cell-autonomous function for Nmnat in the proper maintenance of class IV dendrites.
