A detailed study of dependence of mitochondrial respiration on pH of incubation medium has been carried out. It was shown that during oxidation of malic, succinic and ascorbic acids mitochondrial respiration shows a sharp fall, when the pH of incubation medium is decreased from 7.5 to 6.5. It was assumed that one of the possible causes of the Crabtree effect is a reduction of the pH value of the cytoplasm.

Introduction: It has been reported that even with the same body mass index (BMI), there are subjects with metabolically healthy or unhealthy phenotype. The main determinants of the unhealthy phenotype are the type and distribution of fat, ectopic fat accumulation, genetics, and lifestyle factors. Uncoupling proteins (UCPs) disengage mitochondrial respiration from ATP synthesis and result in heat production, which in turn is related to energy expenditure and, thus, to fat mass accumulation.

The kidney is highly metabolically active, and injury induces changes in metabolism that can impact repair and fibrosis progression. Changes in expression of metabolism-related genes and proteins provide valuable data, but functional metabolic assays are critical to confirm changes in metabolic activity. Stable isotope metabolomics are the gold standard, but these involve considerable cost and specialized expertise.

Background: Resmetirom, the first FDA-approved drug for nonalcoholic steatohepatitis (NASH) with fibrosis in obese patients, when combined with lifestyle modifications, improves NASH resolution and reduces fibrosis by at least one stage. Low thyroid hormone (T) levels are linked to a higher risk of developing metabolic dysfunction-associated steatotic liver disease (MASLD). Epidemiological studies have confirmed the positive correlation between hypothyroidism and MASLD.

Background: Many cancer cells exhibit aberrant metabolic reprogramming through abnormal mitochondrial respiration. Protein tyrosine phosphatase mitochondrial 1 (PTPMT1) is a protein tyrosine phosphatase localized to the mitochondria and linked to mitochondrial respiration. However, the expression and role of PTPMT1 in regulating the biological characteristics of small cell lung cancer (SCLC) has not yet been explored.

Background: Obesity is a chronic disease associated with increased risk of multiple metabolic and mental health-related comorbidities. Recent advances in obesity pharmacotherapy, particularly with glucagon-like peptide-1 (GLP-1) receptor agonists (RAs), have the potential to transform obesity and type 2 diabetes mellitus (T2DM) care by promoting marked weight loss, improving glycaemic control and addressing multiple obesity-related comorbidities, with added cardio-renal benefits. Dual agonists combining GLP-1 with other enteropancreatic hormones such as glucose-dependent insulinotropic polypeptide (GIP) have also been developed in recent years, leading to greater weight loss than using GLP-1 RAs alone.
