The MDM2–p53–pyruvate carboxylase signalling axis couples mitochondrial metabolism to glucose-stimulated insulin secretion in pancreatic β-cells

open access: yesNature Communications, 2016
Mice lacking the tumour suppressor p53 are partially protected from developing diabetes. Here the authors show that p53 is upregulated in the pancreas of diabetic mice where it impairs β cell function by repressing expression of mitochondrial pyruvate ...

Enhanced Ca2+-dependent glutamate release from astrocytes of the BACHD Huntington's disease mouse model

open access: yesNeurobiology of Disease, 2013
Huntington's disease (HD) causes preferential loss of a subset of neurons in the brain although the huntingtin protein is expressed broadly in various neural cell types, including astrocytes.

Isolation and Characterization of Random Citrate Synthase Variants That Increase Acetate Generation by Escherichia coli

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT A method to select Escherichia coli citrate synthase variants having reduced activity was developed based initially on the increased generation of acid, observed visually by prolonged color change in the pH indicator bromocresol purple. Five hundred fifty‐two potential variants were isolated and each were cultured on glucose as sole carbon ...

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

open access: yesBMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Inherited metabolic epilepsies–established diseases, new approaches

open access: yesEpilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Acute control of fatty acid synthesis by cyclic AMP in the chick liver cell: possible site of inhibition of citrate formation.

open access: yesJournal of Lipid Research, 1979
Glucagon and N,(6)O(2)-dibutyryl cyclic adenosine 3‘,5‘-cyclic monophosphate (Bt(2)cAMP) inhibit fatty acid synthesis from acetate by more than 90% and prevent citrate formation in chick hepatocytes metabolizing glucose.

Kinetic modelling of β‐cell metabolism reveals control points in the insulin‐regulating pyruvate cycling pathways

open access: yesIET Systems Biology, 2023
Insulin, a key hormone in the regulation of glucose homoeostasis, is secreted by pancreatic β‐cells in response to elevated glucose levels. Insulin is released in a biphasic manner in response to glucose metabolism in β‐cells.

ATP Citrate Lyase in Metabolic Disease: Mechanistic Insights and Clinical Potential

open access: yesiNew Medicine, EarlyView.
ATP citrate lyase (ACLY) is a central metabolic hub that diverts mitochondrial citrate to fuel de novo lipogenesis, cholesterol biosynthesis, and protein acetylation. Given its robust correlation with pathological changes in multiple human diseases, ACLY inhibitors featuring distinct pharmacological strengths have been developed for therapeutic ...

Bisphenol A and Its Analogs: Toxicity Analysis in Mouse and Rat Liver—A Review

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) and its analogs are widely recognized for their use in industry and plastic manufacturing. Consequently, humans and animals are continually exposed to various substances in their daily lives. This review evaluates the hepatic toxicity of BPA and its analogs in mice and rats, with particular emphasis on molecular mechanisms ...
