MORISAKI, N., MATSUOKA, N., SHIRAI, K., SASAKI, N., SAITO, Y. and KUMAGAI, A. Effect of Pantethine on Fatty Acid Oxidation in Microvessels of Rat Brain. Tohoku J. exp. Med., 1983, 141 (1), 41-45 - Fatty acid oxidation in brain microvessels decreased greatly when persistent hypertension developed in spontaneously hypertensive rats (SHR). Treatment of SHR with pantethine [D-bis-(N-pantothenyl-β-aminoethyl) disulfide] in vivo for 4 weeks restored their fatty acid oxidation activity to the control level. The mechanism of the activating effect of pantethine on fatty acid oxidation was investigated in brain microvessels. Pantethine and its metabolites (pantetheine and 4'-phosphopantetheine) activated three steps of fatty acid oxidation, i.e., acyl-CoA synthetase, carnitine acyltransferase and intramitochondrial oxidation. The relation between changes in fatty acid oxidation activities and injuries of brain microvessels and the protective effect of pantethine against such injuries is discussed.
