Detailed Description
| |||
Statement Reference Acsl[05847] mutant survive to the pharate adult stage.
In the cross section of the larval segmental nerves of Acsl[KO]/Acsl[05847] mutants, there are conspicuous axonal swellings packed with heterogeneous membranous organelles. These aggregates, most often observed in posterior axons, include dark, prelysosomal and multivesicular bodies. In some mutant larvae, autophagosomes are also observed where a cluster of large clear-core vesicles are surrounded by a double-layer membrane. The mutant nerves also display lamellated bodies which resemble autolysosomes. In other cases, clusters of large clear-core vesicles are observed. These membrane aggregates are rarely found in wild-type axons.
Acsl[KO]/Acsl[05847] mutants display pronounced dystrophy of larval neuromuscular junction 4 (NMJ4) in the posterior abdominal segments A6 and A7, while the muscle and larval size are comparable to wild-type. The bouton number and the synaptic area are significantly reduced in Acsl[KO]/Acsl[05847] mutants compared with wild-type.
The synaptic area of Acsl[KO]/Acsl[05847] in Acsl[KO]/Acsl[05847] mutants is comparable to that of wild-types 2 days after egg laying (AEL). Synapse growth during 2-3.5 days AEL of Acsl[KO]/Acsl[05847] mutants is markedly slower than that in wild-types. From 3.5 to 5 days AEL, the mutant NMJ synapses apparently retract.
The evoked excitatory junction potentials (EJPs) are significantly reduced in Acsl[KO]/Acsl[05847] mutant larvae recorded from muscle 6 in the posterior abdominal segment. Miniature EJPs (mEJPs, also known as quantal size) are normal in Acsl[KO]/Acsl[05847] mutants. Quantal content is significantly reduced in Acsl[KO]/Acsl[05847] mutants. Neutral lipid accumulation is blocked in Acsl[8]/Acsl[05847] wing discs.
Total triacylglycerol content of Acsl[8]/Acsl[05847] pharates is significantly lower than wild type. Neuroblast squashes reveal premature separation of sister chromatids during prophase and metaphase, overcondensed chromosomes in metaphase and anaphase, and anaphases with different degrees of abnormalities. Spindles are abnormal, some being of abnormal shape and others failing to connect all the chromosomes. | |||

Statement Reference Expression of Hsap\ACSL4[Scer\UAS.L.T:Hsap\MYC] in postsynaptic muscles driven by Scer\GAL4[Mhc.PW] does not suppress the dystrophic neuromuscular junctions of Acsl[KO]/Acsl[05847] mutants for bouton number.
Neuronal expression of Hsap\ACSL4[Scer\UAS.L.T:Hsap\MYC] at 2.5 days after egg laying (AEL) fully suppresses the reduced synaptic area phenotype of Acsl[KO]/Acsl[05847] mutants.
Neuronal expression of Hsap\ACSL4[Scer\UAS.L.T:Hsap\MYC] driven by Scer\GAL4[elav.PU] restores the bouton number to wild-type levels in Acsl[KO]/Acsl[05847] mutants.
The neuromuscular junction phenotypes of Acsl[KO]/Acsl[05847] mutants can be fully suppressed by ubiquitous expression of Hsap\ACSL4[Scer\UAS.L.T:Hsap\MYC] under the control of Scer\GAL4[αTub84B.PL].
The reduced EJPs and quantal content are fully rescued by Hsap\ACSL4[Scer\UAS.L.T:Hsap\MYC] expressed in either ubiquitously via Scer\GAL4[αTub84B.PL] or pan-neuronally via Scer\GAL4[elav.PU]. EJPs in animals with Hsap\ACSL4[Scer\UAS.L.T:Hsap\MYC] expressed pan-neuronally are mildly but significantly higher than that in wild-types.
Postsynaptic expression of Hsap\ACSL4[Scer\UAS.L.T:Hsap\MYC] driven by Scer\GAL4[Mhc.PW] in Acsl[KO]/Acsl[05847] mutant background slightly suppressed the EJP phenotype. Expression of Hsap\ACSL4[Scer\UAS.L.T:Hsap\MYC] or Hsap\ACSL3[Scer\UAS.T:Hsap\MYC] under the control of Scer\GAL4[tub] partially rescues the lethality associated with the Acsl[8]/Acsl[05847] genotype.
Expression of Hsap\ACSL4[R570S.Scer\UAS.L.T:Hsap\MYC] or Hsap\ACSL4[P375L.Scer\UAS.L.T:Hsap\MYC] under the control of Scer\GAL4[tub] fails to rescue the lethality associated with the Acsl[8]/Acsl[05847] genotype.

Expression of Hsap\ACSL4[R570S.Scer\UAS.L.T:Hsap\MYC] or Hsap\ACSL4[P375L.Scer\UAS.L.T:Hsap\MYC] under the control of Scer\GAL4[tub] fails to restore neutral lipid staining in Acsl[8]/Acsl[05847] wing discs.
Expression of Hsap\ACSL4[Scer\UAS.L.T:Hsap\MYC] under the control of Scer\GAL4[tub] restores normal triacylglycerol levels in Acsl[8]/Acsl[05847] wing discs. | |||
