Ectopic expression of myshs.PB has no effect on olfactory function.
Overexpression of myshs.PB using heat shock every 7 hours from hatching results in larval and pupal lethality. Larvae that survive to the wandering third instar stage often undergo premature histolysis. At a qualitative level, the neuromuscular junctions of the heat shocked larvae are structurally disordered, with reduced branches and smaller, abnormally shaped boutons. Muscle 4 terminals show no significant alterations in the number of synaptic branches or type I boutons. In contrast, muscle 12 terminals show a significant decrease in the number of total synaptic branches, resulting primarily from a loss of higher order branches, and a highly significant decrease in the number of type I boutons.
