mitochondrial crista & indirect flight muscle
The DA neurons of Pink15 adults exhibit aggregated or elongated mitochondria.
Pink15/+ heterozygous mutants have significantly reduced mitochondrial length and significantly increased mitochondrial number in axons of adult neurons, compared to controls.
Pink15 mutant embryos display asymmetric frontal ganglia and altered esophageal ganglia, as compared to controls.
Pink15 hemizygous male third instar larvae show nearly fully penetrant mitochondrial defects in the body wall muscles, including a rounder shape, an "onion"-like crista phenotype, a "vacuole" phenotype and decreased number of crista junctions, but no changes in mitochondria size; there are no obvious muscle degeneration signs in these larvae. In the nervous system, mitochondria cristae defects are observed in the ventral nerve cord neuropils (synapses, dendrites, and axons, but not in the cell bodies), in the segmental nerves (axons), and at the neuromuscular junctions. These larvae have impaired crawling ability.
In 3 days old Pink15 hemizygous male adults, indirect flight muscles present vacuolated and "onion"-like mitochondria, all of which convert to vacuolated mitochondria at day 5; at day 5 these indirect flight muscles show signs of degeneration.
Pink15 mutant escapers do not exhibit lipid droplet accumulation. Aconitase activity is reduced in these mutants and there is a strong correlation between decreased aconitase enzymatic activity and the number of lipid droplets per ommatidium, suggesting reactive oxygen species may play a role in lipid droplet accumulation.
Pink15 mutant flies show elevated response across a range of spatiotemporal frequencies of contrast-reversing sine-wave gratings as compared to responses from control flies.
PPL1 dopaminergic neurons in the brain have abnormally clumped mitochondria in mutant adults.
Mutants show severe defects in mitochondrial morphology in the indirect flight muscle (IFM): mitochondrial size is irregular and clumping of mitochondria are seen. Many of the mitochondria are swollen and have fragmented cristae. The mutant muscle shows cell death and vacuolisation, indicating degeneration. The mutant adults have a thoracic indentation due to this degeneration of the IFM.
Mutant spermatids show vacuolated onion-stage nebenkerns, and in subsequent stages, show only one mitochondrial derivative rather than the normal two seen in wild-type spermatids. A cross-section through mutant sperm tails shows the presence of only the major mitochondrial derivative, but not the minor mitochondrial derivative.
Indirect flight muscles of mutant flies show severe defects in mitochondrial morphology, including swollen mitochondria with broken cristae. Vacuolisation, indicative of degeneration, is seen in the indirect flight muscles.
Mutant adults have an abnormal wing posture.
Pink15 mutant males exhibit mitochondrial morphology defects in the testes. Spermatids show vacuolisation in the spherical "onion stage" nebenkern. Only one mitochondrial derivative is seen during spermatid elongation (the "leaf blade" stage), as opposed to the two usually seen in wild type. Pink15 mutant spermatids also exhibit dramatic defects in mitochondrial morphology during the post-individualisation stages.
An-age dependent decrease in the number of dopaminergic neurons is seen in Pink15 mutant flies. Fewer neurons are observed in 40 day old flies at 25[o]C. Pink15 mutant flies also show striking indirect flight muscle degeneration and severely disrupted mitochondrial morphology with broken cristae.
Indirect flight muscles of 1-2 day old mutant adults show a marked increase in TUNEL-positive nuclei compared to controls, indicating an increase in the number of apoptotic cells.
Mutant flies show a 59% reduction in resistance to paraquat and a 71% reduction in resistance to rotenone compared to controls. They are also more sensitive to dithiothreitol and to high concentrations of salt compared to wild-type flies.
Mutant males show vacuolation of Nebenkern in the testes.
The indirect flight muscles of 2 day old flies have mitochondria with fragmented cristae.
