Description:
C6 glioma cells and B104 neuroblastoma cells both possess adenylate cyclase activity, but only C6 cells have beta-adrenergic receptors. However, when cocultured with B104 cells, C6 cells show a marked decrease in their ability to accumulate adenosine 3', 5'-monophosphate upon stimulation with beta receptor agonists. Since both beta receptors and cholera toxin-stimulated adenylate cyclase activities are present in C6/B104 cocultures, we conclude that the beta receptor/adenylate cyclase transduction mechanism in cocultured C6 cells is uncoupled.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ciment, G -- de Vellis, J -- New York, N.Y. -- Science. 1978 Nov 17;202(4369):765-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/213832" target="_blank"〉PubMed〈/a〉
