adult heart, with Scer\GAL4tin.CΔ4
Flies expressing MarfmiRNA.cUa.Scer\UAS under the control of Scer\GAL4tin.CΔ4 show a dilated cardiomyopathy characterised by mitochondria with fewer genomes, increased reactive oxygen species (ROS) and greater depolarization. There is no reduction in mitochondrial DNA.
Expression of MarfmiRNA.cUa.Scer\UAS under the control of Scer\GAL4ey.3.5.Exel results in an approximately 30% reduction in eye area and results in ommatidial disorganisation.
Flies expressing MarfmiRNA.cUa.Scer\UAS under the control of Scer\GAL4tin.CΔ4 show a progressive reduction in climbing activity compared to controls as they age. Heart tube fractional shortening is significantly depressed in the mutant flies at 4 weeks of age.
Expression of MarfmiRNA.cUa.Scer\UAS under the control of Scer\GAL4tin.CΔ4 increases mitochondrial heterogeneity, induces mitochondrial fragmentation in adult cardiomyocytes and shifts the population distribution towards smaller mitochondria.
Adults expressing MarfmiRNA.cUa.Scer\UAS under the control of Scer\GAL4tin.CΔ4 have normal longevity.
Mitochondria tend to cluster in aggregates that distort the normal myofibrillar architecture in cardiomyocytes of adults expressing MarfmiRNA.cUa.Scer\UAS under the control of Scer\GAL4tin.CΔ4. The mitochondria appear heterogeneous, with both mitochondrial fragments and enlarged mitochondria being seen. Mean mitochondrial size is decreased approximately 30% compared to wild type. T-tubules and sarcoplasmic reticulum appears morphologically normal in the mutant cardiomyocytes.
The heart tubes of adults expressing MarfmiRNA.cUa.Scer\UAS under the control of Scer\GAL4tin.CΔ4 are dilated compared to wild type and show impaired shortening with no change in the beating rate.

Co-expression of MarfmiRNA.cUa.Scer\UAS and parkHMS01651 under the control of Scer\GAL4tin.CΔ4 suppresses the heart tube cardiomyopathy and some of the mitochondrial defects seen when either transgene is expressed alone. The proportion of reactive oxygen species (ROS)-producing and depolarized organelles is reduced, and the reduction in mitochondrial DNA content usually seen in flies expressing parkHMS01651 is rescued. However, the mitochondria show characteristics of both parent lines: they are still enlarged as is seen in parkHMS01651, and appear fragmented as is seen with MarfmiRNA.cUa.Scer\UAS.
