Application

Oxotremorine M has been used as a muscarinic acetylcholine receptor (mAchR) agonist:
  • to study its acute effects on the movement of Caenorhabditis elegans
  • to treat hippocampal neurons for studying fibroblast growth factor receptor 1 (FGFR1) phosphorylation
  • to induce bladder overactivity in rats

Caenorhabditis elegans male copulation requires coordinated temporal-spatial execution of different motor outputs. During mating, a cloacal circuit consisting of cholinergic sensory-motor neurons and sex muscles maintains the male's position and executes copulatory spicule thrusts at his mate's vulva. However, distinct
