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

Nature 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

Neurobiology 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.

Activation of AMP-activated protein kinase by metformin induces protein acetylation in prostate and ovarian cancer cells [PDF]

, 2016
AMP-activated protein kinase (AMPK) is an energy sensor and master regulator of metabolism. AMPK functions as a fuel gauge monitoring systemic and cellular energy status.

Mitochondrial Enzymes Mimetic Ultrasmall Palladium Nanozymes Prevent Senescence and Neurodegeneration Through Metabolic Reprogramming

Advanced Science, EarlyView.
Simply constructed polyvinylpyrrolidone (PVP) modified palladium nanoparticles (PdP NPs) as cytochrome c oxidase (CcO) and superoxide dismutase (SOD) mimic are promising multifunctional nanoreactors to boost mitochondrial respiration chain function and refine homeostasis via regulation of mitochondrial dynamics and proteostasis sensor UPRmt, which ...

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

IET 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.

ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]

, 1987
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Hepatotoxicity of Nonesterified Fatty Acids to Dairy Cows: Pathophysiological Mechanisms and Prospective Solutions

Animal Research and One Health, EarlyView.
Unregulated inflammation increases non‐esterified fatty acids (NEFAs), and triggers multi‐pathway hepatocyte damage including oxidative stress, mitochondrial dysfunction, and metabolic disorders in dairy cows. ABSTRACT Circulating concentrations of nonesterified fatty acids (NEFAs) are elevated due to lipid mobilization from adipose tissue in ...

Advancing Malic Acid Production of Aspergillus oryzae: Combined Process Optimization and Application of Various Substrates

Biotechnology and Bioengineering, EarlyView.
ABSTRACT In light of climate change and growing resource scarcity, microbial production of organic acids offers a sustainable alternative to fossil‐based chemical synthesis. In this study, malic acid production by Aspergillus oryzae was optimized through cultivation temperature adjustment and biotin supplementation, while organic acid formation from ...

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

Journal 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.
