The brain acylcarnitine profile depends on nutritional state
MicroRNAs (miRNAs) are short, 22–25 nucleotide long transcripts that may suppress entire signaling pathways by interacting with the 3’-untranslated region (3’-UTR) of coding mRNA targets, interrupting translation and inducing degradation of these targets. The long 3’-UTRs of brain transcripts compared to other tissues predict important roles for brain miRNAs. Supporting this notion, we found th...
متن کاملAn LC-MS/MS method to quantify acylcarnitine species including isomeric and odd-numbered forms in plasma and tissues.
Acylcarnitines are intermediates of fatty acid and amino acid oxidation found in tissues and body fluids. They are important diagnostic markers for inherited diseases of peroxisomal and mitochondrial oxidation processes and were recently described as biomarkers of complex diseases like the metabolic syndrome. Quantification of acylcarnitine species can become challenging because various species...
متن کاملCharacterization of carnitine acylcarnitine translocase system of heart mitochondria.
Mersalyl inhibited the respiration of heart mitochondria under conditions that required the transport of (-)-carnitine and acyl(-)-carnitines. The exchange of external carnitine and acylcarnitines for intramitochondrial carnitine was also inhibited by mersalyl and 1 mM mersalyl proved suitable for the inhibitor-stop assay of carnitine acylcarnitine translocase. The carnitine-carnitine and (-)-c...
متن کاملA mitochondrial carnitine acylcarnitine translocase system.
Acetylation of added (-)carnitine by heart mitochondira coupled to the oxidation of pyruvate in the presence of malonate was inhibited, apparently competitively, by long chain acyl(+)carnitines although the activity of carnitine acetyltransferase (EC 2.3.1.7) itself was not affected. Mitochondria have been found to possess a translocase system that allows the transport of carnitine and acylcarn...
متن کاملPregnancy-Related Changes of Amino Acid and Acylcarnitine Concentrations: The Impact of Obesity
Objective Our primary objective was to assess the difference in amino and fatty acid biomarkers throughout pregnancy in women with and without obesity. Interactions between biomarkers and obesity status for associations with maternal and fetal metabolic measures were secondarily analyzed. Methods Overall 39 women (15 cases, 24 controls) were enrolled in this study during their 15- to 20-weeks' ...
