Detailed Description

Reference

Third instar larvae expressing MiroKK102189 under the control of Scer\GAL4CCAP.PP show a severe decrease in both anterograde and retrograde axonal transport of mitochondria, as compared to controls.

Embryos derived from females expressing MiroKK102189 under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 show an increase in ventral midline cell division at the end of germband shortening. The mutant embryos show an average of 11.1 mitotic cells in total in the 10 trunk neuromeres (compared to 4.8 cells in wild type).

Expression of MiroKK102189 under the control of Scer\GAL4elav.PU results in an increase in mitochondrial content in adult neuronal cell bodies. However these mitochondria do not display any morphology defects. Mitochondrial length is similar to controls.

Expression of MiroKK102189 in eyes under the control of Scer\GAL4GMR.PF results in loss of mitochondria in the synaptic terminals of the photoreceptor neurons. Degeneration is seen in the lamina of 40 day old flies.

Expression of MiroKK102189 under the control of Scer\GAL4ple.PF in larval motor neurons results in decreased axonal mitochondrial transport flux and velocity in both anterograde and retrograde directions, decreased mitochondrial length, and decreased accumulation of mitochondria in the most distal boutons of neuromuscular junctions, as compared with controls.

Glial cells show mis-distribution of mitochondria in third instar larvae expressing MiroKK102189 under the simultaneous control of both Scer\GAL4repo.PL and Scer\GAL4repo.

Expression of MiroKK102189 in ddaE neuronal soma under the control of Scer\GAL4elav-C155 reduces by 50% the number of mitochondria in the dorsal comb-like dendrite. Severed dendrites lacking mitochondria are completely removed by 12-18 hours, as in controls.

The ability of rictorΔ2 to enhance the abnormal wing posture phenotype seen in flies expressing Pink1dsRNA.Scer\UAS under the control of Scer\GAL4Mhc.PW is partially suppressed by co-expression of MiroKK102189.

The ability of trcK122A.Scer\UAS.T:Zzzz\FLAG to enhance the abnormal wing posture phenotype seen in flies expressing Pink1dsRNA.Scer\UAS under the control of Scer\GAL4Mhc.PW is partially suppressed by co-expression of MiroKK102189.

Expression of MiroKK102189 under the control of Scer\GAL4Mhc.PU partially rescues the abnormal wing posture and flight defects of Pink1B9/Pink1B9 mutants.

Expression of MiroKK102189 under the control of Scer\GAL4ple.PF rescues the dopaminergic neuron loss and mitochondrial aggregation phenotypes of Pink1B9/Pink1B9 mutant adults.
