Description:
Approximately 25 percent of resting energy utilization in isolated nerve endoneurium is inhibited by medium containing defatted albumin and selectively restored by arachidonic acid but is unaffected by indomethacin or nordihydroguaiaretic acid. The same component of energy utilization is inhibited by small decreases in endoneurial myo-inositol, which decrease incorporation of carbon-14-labeled arachidonic acid into phosphatidylinositol. The fraction of the resting oxygen uptake inhibited by ouabain is decreased 40 to 50 percent by a reduced tissue myo-inositol concentration or by defatted albumin. Metabolic regulation by rapid, basal phosphatidylinositol turnover is dependent on the maintenance of normal tissue myoinositol concentrations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simmons, D A -- Winegrad, A I -- Martin, D B -- T32 AMO7314/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):848-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6285474" target="_blank"〉PubMed〈/a〉
