Hyperpolarized [1,3-13C2 ]ethyl acetoacetate is a novel diagnostic metabolic marker of liver cancer.
An increased prevalence of liver diseases such as hepatitis C and nonalcoholic fatty liver results in an augmented incidence of the most common form of liver cancer, hepatocellular carcinoma (HCC). HCC is most often found in the cirrhotic liver and it can therefore be challenging to rely on anatomical information alone when diagnosing HCC. Valuable information on specific cellular metabolism ca...
متن کاملAcetoacetate Formation in Liver
In 1944, Weinhouse et al. (1) reported that the incubation of carboxyllabeled octanoate with rat liver slices yielded acetoacetate in which the carboxyl and carbonyl carbons were equally labeled. Random condensation of 2-carbon units resulting from ,8 oxidation was therefore offered by these workers as a possible mechanism for the formation of acetoacetic acid from octanoate. The conversion of ...
متن کاملThe mechanism of acetoacetate synthesis.
The observation of a coenayme A (CoA)-catalyzed acetoacetate synthesis from acetate and adenosinetriphosphate in pigeon liver extracts (1) grouped this reaction with the larger family of acetylation reactions. Furthermore it furnished partial confirmation of an earlier calculation (2) showing that 16,000 calories are required for the condensation of two acetates to acetoacetate. Thus, one energ...
متن کاملAcetoacetate Metabolism in Rat Brain
1. Data are provided that indicate that the rat brain acetoacetyl-CoA deacylase is almost exclusively mitochondrial. Developmental studies show that this enzyme more than doubles its activity during suckling (0-21 days) and then maintains this activity in adults (approx. 1.1 units/g wet wt.). 2. Kinetic studies (on the acetoacetyl-CoA deacylase) in a purified brain mitochondrial preparation giv...
متن کاملAcetoacetate and acetate, intermediates in glutarate catabolism.
The labeling patterns found in tissue glutamate, aspartate, and alanine after administration of glutaric acid-3-Cl4 to male rats (1) indicated that the major catabolic route of glutarate is via acetate (2) and not via a direct conversion to the carbon chain of cu-ketoglutarate (3-5). In further studies on the metabolism of glutarate-3-C14 in rats, we have observed the formation of urinary acety...
