      Expression of SmndsRNA.Scer\UAS.cUa driven by Scer\GAL4tub.PU results in pupal lethality (44% early, 56% late) and modestly decreases synaptic innervation in third instar larval neuromuscular junctions (slight decrease in bouton numbers per muscle area), compared to controls.

      Fimd02114, Fimd03334 or Fimf04028 accelerate pupal lethality (significant shift towards earlier rather than late pupal lethality) in Scer\GAL4tub.PU>SmndsRNA.Scer\UAS.cUa animals.

      Fimd02114/Fimd02114 third instar larvae with expression of SmndsRNA.Scer\UAS.cUa driven by Scer\GAL4tub.PU show significant decreases in the number of boutons per muscle area at the neuromuscular junction.
