Ketogenesis is a dynamic metabolic conduit supporting hepatic fat oxidation particularly when carbohydrates are in short supply. Ketone bodies may be recycled into anabolic substrates, but a physiological role for this process has not been identified. Here, we use mass spectrometry-based C-isotope tracing and shotgun lipidomics to establish a link between hepatic ketogenesis and lipid anabolism.

Objectives: While ketone bodies are not the main heart fuel, exercise may increase their uptake. Objectives: This study aimed to investigate the effect of 6-week endurance training and Pyruvate dehydrogenase kinase 4 )PDK4( inhibition on ketone bodies metabolism in the heart of diabetic rats with emphasis on the role of Peroxisome proliferator-activated receptor-gamma coactivator PGC-1alpha (PGC-1α).
Materials And Methods: Sixty male Wistar rats were divided into eight groups: healthy control group (CONT), endurance training group (TRA), diabetic group (DM), DM + EX group, Dichloroacetate (DCA) group, DM + DCA group, TRA + DCA group, and DM + TRA + DCA group.

Objectives: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are now widely used for treating type 2 diabetes mellitus (T2DM) and obesity. We examined their association with acetonemic vomiting, especially when given to patients with low body weight, in hopes of achieving early recognition of this complication which is potentially life-threatening if not dealt with appropriately.
Methods: Cases identified incidentally are described and discussed referring to prior reports.

Context: The impacts of elevated ketone body levels on cardiac function and hemodynamics in patients with heart failure (HF) remain unclear.
Objective: The effects of ketone intervention on these parameters in patients with HF were evaluated quantitatively in this meta-analysis.
Data Sources: We searched the PubMed, Cochrane Library, and Embase databases for relevant studies published from inception to April 13, 2024.

Diabetic cardiomyopathy (DbCM), a significant chronic complication of diabetes, manifests as myocardial hypertrophy, fibrosis, and other pathological alterations that substantially impact cardiac function and elevate the risk of cardiovascular diseases and patient mortality. Myocardial energy metabolism disturbances in DbCM, encompassing glucose, fatty acid, ketone body and lactate metabolism, are crucial factors that contribute to the progression of DbCM. In recent years, novel protein post-translational modifications (PTMs) such as lactylation, β-hydroxybutyrylation, and succinylation have been demonstrated to be intimately associated with the myocardial energy metabolism process, and in conjunction with acetylation, they participate in the regulation of protein activity and gene expression activity in cardiomyocytes.
