background apo-lipoprotein e (apoe) and carnitine palmitoyltransferase1-a (cpt1-a) genes are well known to be involved in the pathophysiology of psychiatric disorders such as schizophrenia but regarding their cpg island methylation status data is sparse. objectives the aims of the current study were to highlight the effect of the promoter “hypermethylation” in the development of scz. patients a...

1. Liver carnitine acyltransferase activities with palmitoyl-CoA and octanoyl-CoA as substrates and heart carnitine palmitoyltransferase were measured as overt activities in whole mitochondria or in mitochondria disrupted by sonication or detergent treatment. All measurements were made in sucrose/KCl-based media of 300 mosmol/litre. 2. In liver mitochondria, acyltransferase measured with octano...

Lysine succinylation was recently identified as a post-translational modification in cells. However, the molecular mechanism underlying lysine succinylation remains unclear. Here, we show that carnitine palmitoyltransferase 1A (CPT1A) has lysine succinyltransferase (LSTase) activity in vivo and in vitro. Using a stable isotope labeling by amino acid in cell culture (SILAC)-based proteomics appr...

Nonalcoholic fatty liver disease (NAFLD), hypertriglyceridemia, and elevated free fatty acids are present in the majority of patients with metabolic syndrome and type 2 diabetes mellitus and are strongly associated with hepatic insulin resistance. In the current study, we tested the hypothesis that an increased rate of fatty acid oxidation in liver would prevent the potentially harmful effects ...

Carnitine palmitoyltransferase of liver mitochondria prepared from ketotic diabetic rats has a diminished sensitivity to inhibition by malonyl-CoA compared with carnitine palmitoyltransferase of mitochondria prepared from normal fed rats.

Treatment of female rats with ethynyloestradiol decreased both the activity of carnitine palmitoyltransferase and its Ki value for malonyl-CoA compared with pair-fed control rats. In starved rats, carnitine palmitoyltransferase activity and its Ki value for malonyl-CoA were both elevated as expected. Oestrogen treatment had no effect on carnitine palmitoyltransferase activity in the starved sta...
