Chemical compound and disease context of ache

 

Biological context of ache

  • Remarkably, the ratio of AAA/AChE activity decreased 210-fold from 4 to 144 h development, indicating a distinct embryonic role of AAA during early embryogenesis [8].
  • Blocking acetylcholinesterase (AChE) with eserine had no effect on mEPC kinetics in embryos at 1 day and only partially slowed (by approximately 1/2) the decay rate in larvae at 6 days [9].
  • The primary neurons appear to follow a common sequence of development consisting of a withdrawal from the cell division cycle, the expression of AChE, and axogenesis [10].
  • Contrary to the predictions of this model, we find similar delay and onset kinetics of synaptic current at positive and negative muscle membrane potentials, even after inhibition of acetylcholinesterase [11].
 

Anatomical context of ache

  • In contrast to previous results using a catalytic-inactive allele, our analysis demonstrates that AChE is dispensable for muscle fiber development and Rohon-Beard sensory neuron growth and survival [5].
  • Moreover, we show that in the absence of AChE, acetylcholine receptor clusters at neuromuscular junctions initially assemble, but that these clusters are not maintained [5].
  • Acetylcholinesterase function is dispensable for sensory neurite growth but is critical for neuromuscular synapse stability [5].
  • ChAT-ir cells were restricted to the periventricular stratum of the optic tectum, but AChE-positive neurons were observed throughout the whole extension of the lamination except in the marginal stratum [12].
  • Presumptive cranial ganglia transiently expressed AChE activity between 14 and 24 hours of development [10].
 

Associations of ache with chemical compounds

  • Acetylcholinesterase inhibition and increased food consumption rate in the zebrafish, Danio rerio, after chronic exposure to parathion [13].
  • The AAA activity was sensitive to eserine and serotonin, ensuring its association with AChE [8].
  • The results showed that the observed cholinesterase activities in the whole embryo may be attributed mainly to acetylcholinesterase with a partial capability to use propionylthiocholine as a second substrate [14].
  • Besides AChE activity, a variety of other parameters were measured: whole-body protein and lactate content, consumption rate, survival, growth and reproduction [13].
  • Widespread innervation of the swim bladder was also indicated by acetylcholinesterase histochemistry, but choline acetyltransferase-immunoreactive (-IR) somata and fibers were limited to the junction of the pneumatic duct and esophagus [15].
