Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia 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.

Refinement of odor molecule tuning by dendrodendritic synaptic inhibition in the olfactory bulb.

Proceedings of the National Academy of Sciences of the United States of America, 1995
Mitral/tufted cells (M/T cells) and granule cells form reciprocal dendrodendritic synapses in the main olfactory bulb; the granule cell is excited by glutamate from the M/T cell and in turn inhibits M/T cells by gamma-aminobutyrate.

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

Journal of the Chinese Chemical Society, EarlyView.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

The metabolic reprogramming of γ-aminobutyrate in oral squamous cell carcinoma

BMC Oral Health
Oral squamous cell carcinoma (OSCC) is the most common head and neck malignancy. The oncometabolites have been studied in OSCC, but the mechanism of metabolic reprogramming remains unclear.

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

The FEBS Journal, EarlyView.
The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and

Fecal metabolite of a gnotobiotic mouse transplanted with gut microbiota from a patient with Alzheimer’s disease

Bioscience, biotechnology and biochemistry, 2019
Studies of Alzheimer’s disease are based on model mice that have been altered by transgenesis and other techniques to elicit pathogenesis. However, changes in the gut microbiota were recently suggested to diminish cognitive function in patients, as well ...

Physiological media and oxygen levels modulate cancer hallmarks in cultured breast cancer cells

The FEBS Journal, EarlyView.
MCF7 breast cancer cells were cultured in standard conditions (18% O2 and DMEM) and physiological conditions (5% O2 and Plasmax, a medium modeled after the human plasma metabolome). A combined transcriptomic and proteomic approach was used to identify gene expression signatures at the mRNA and protein levels upstream of functional enrichment analyses ...

Comparative metabolic profiling of the lipid-producing green microalga Chlorella reveals that nitrogen and carbon metabolic pathways contribute to lipid metabolism

Biotechnology for Biofuels, 2017
Microalgae are a promising feedstock for biofuel production. Microalgal metabolic pathways are heavily influenced by environmental factors. For instance, lipid metabolism can be induced by nitrogen-limiting conditions.

Evaluation of Torula Yeast (Candida utilis) Single Cell Proteins as a Partial Replacement for Soybean Meal in Broiler Diets: Effects on Productive Performance, Meat Quality Traits, and Plasma Metabolome

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Over recent years the use of yeast in feedstuffs has gained momentum due to novel developments in single‐cell proteins (SCPs). SCPs are considered a sustainable protein source, as their production enable to convert low‐value substrates (including industrial/agricultural wastes) into feed, with a related reduced environmental impact. This study

Divergent Atrial Transcriptomic Signatures in Diabetic and Nondiabetic Atrial Fibrillation

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
Diabetes alters the atrial transcriptome in atrial fibrillation, characterized by enhanced mitochondrial ATP synthesis, suppressed immune and inflammatory pathways, and distinct miRNA expression profiles, suggesting metabolic and epigenetic remodeling of the atrial substrate.
