Sex‐dependent effects of a high‐fat diet‐induced obesity model on cerebrovascular health and brain metabolism

open access: yesExperimental Physiology, EarlyView.
Abstract Mid‐life obesity is a major risk factor for neurodegenerative diseases, with mitochondrial and cerebrovascular dysfunction considered key mediators. Lysine acetylation is a reversible post‐translational modification that regulates several mitochondrial metabolic and biochemical processes.

Improvement of succinate production from methane by combining rational engineering and laboratory evolution in Methylomonas sp. DH-1

open access: yesMicrobial Cell Factories
Recently, methane has been considered a next-generation carbon feedstock due to its abundance and it is main component of shale gas and biogas. Methylomonas sp. DH-1 has been evaluated as a promising industrial bio-catalyst candidate.

LDHB contributes to the regulation of lactate levels and basal insulin secretion in human pancreatic β cells

open access: yesCell Reports
Summary: Using 13C6 glucose labeling coupled to gas chromatography-mass spectrometry and 2D 1H-13C heteronuclear single quantum coherence NMR spectroscopy, we have obtained a comparative high-resolution map of glucose fate underpinning β cell function ...

Characteristics of C-4 photosynthesis in stems and petioles of C-3 flowering plants [PDF]

open access: yes, 2002
Most plants are known as C-3 plants because the first product of photosynthetic CO2 fixation is a three-carbon compound. C-4 plants, which use an alternative pathway in which the first product is a four-carbon compound, have evolved independently many ...

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

Integrated Regulatory and Metabolic Networks of the Marine Diatom Phaeodactylum tricornutum Predict the Response to Rising CO2 Levels. [PDF]

open access: yes, 2017
Diatoms are eukaryotic microalgae that are responsible for up to 40% of the ocean's primary productivity. How diatoms respond to environmental perturbations such as elevated carbon concentrations in the atmosphere is currently poorly understood.

Cytosolic Phosphoenoylpyruvate Carboxykinase Deficiency: Clinical, Biochemical, and Genetic Features of Five Non‐Finnish Patients

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1192-1203, June 2026.
ABSTRACT Cytosolic phosphoenoylpyruvate carboxykinase (PEPCK‐C) is an essential, rate‐limiting enzyme in the gluconeogenesis pathway. PEPCK‐C deficiency presents with hypoglycaemia, hyperlactataemia and hepatopathy, and was first reported in association with bi‐allelic PCK1 variants in 2014.

Which way does the citric acid cycle turn during hypoxia? The critical role of alpha-ketoglutarate dehydrogenase complex [PDF]

open access: yes, 2013
The citric acid cycle forms a major metabolic hub and as such it is involved in many disease states involving energetic imbalance. In spite of the fact that it is being branded as a "cycle", during hypoxia, when the electron transport chain does not ...

Oxidative Stress in the Tumor Immune Microenvironment: Mechanisms and Therapeutic Perspectives

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Oxidative stress is involved in several key processes in cancer, including redox regulation, DNA damage, post‐translational modifications, transcriptional regulation, epigenetic modifications, metabolic reprogramming, cell death, and immune modulation. These mechanisms collectively influence tumor progression, immune evasion, and therapeutic responses,
