Dys8-2 exhibits muscular dystrophy-like phenotypes when in combination with Df(3R)Dl-X43
Dys8-2/Df(3R)Dl-X43 mutant flies exhibit mild age-dependent indirect flight muscle degeneration.
With age, Dys8-2/Df(3R)Dl-X43 flies exhibit shorter diastolic
intervals, resulting in increased heart rates and fewer asystoles, and produce a more regular heartbeat than wild-type controls.
Throughout most of their adult life, Dys8-2/Df(3R)Dl-X43 flies have a significantly wider diastolic and systolic diameter, accompanied (from 3 weeks onwards) by a reduced fractional shortening compared to controls.
Dys8-2/Df(3R)Dl-X43 mutant ovaries show oocyte polarity defects.
Dys8-2/Df(3R)Dl-X43 mutant flies show comparable climbing ability at the beginning of adult life to control flies. However, the ability of these animals to climb declines significantly faster over time compared to controls. Animals exhibit mostly normal muscle architecture at 3 days after eclosion. By 12 days, age-dependent muscle degeneration is observed including loss of muscle fibre organisation, vacuolisation and the absence of some muscles.
Retinal photoreceptor cells are not elongated in Dys8-2/Df(3R)Dl-X43 mutant eyes. In third instar larval eye discs, neuronal projections from photoreceptor neurons to the brain optic lobes are disturbed. Axons stop irregularly, making gaps in the normal termination zone of the lamina plexus, deviating from the path and bundling aberrantly.
Dys8-2/DysE6 mutant third instar larval eye discs develop aberrant neuronal projections from photoreceptor neurons to the brain optic lobes. Axons stop irregularly, making gaps in the normal termination zone of the lamina plexus, deviating from the path and bundling aberrantly. This axon projection phenotype not observed in Dys8-2/+ mutant discs.
