Optimised production of L-glutaminase: A tumour inhibitor from Aspergillus flavus cultured on agroindustrial residues [PDF]

, 2013
L-Glutaminase, an amidohydrolase enzyme has been a choice of interest in the treatment of lymphoblastic leukemia. This study investigates the production and optimization of extracellular glutaminase enzyme using several agro-industrial residues by ...

Phenotypic characterization of Arabidopsis thaliana mutants that alleviate root growth defects in a vitamin B6 biosynthesis mutant

The FEBS Journal, EarlyView.
Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics

The FEBS Journal, EarlyView.
This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...

CD36‐mediated lipid rewiring in the metabolic adaptation of tumour ecosystems

The FEBS Journal, EarlyView.
Nutrient deprivation drives a lipid‐centric shift in tumour metabolic symbiosis and signalling network. CD36 functions as a bidirectional bridge, transferring fatty acids from stromal donors (adipocytes, CAFs) to the ecosystem tumour‐ and microenvironment‐dependently.

A new L-glutaminase from Kosakonia sp.: extracellular production, gene identification and structural analysis

, 2021
A comprehensive research has been carried out on L-glutaminase producers from marine bacteria. Among the evaluated isolates, Kosakonia radicincitans was found to be a L-glutaminase producer from a marine environment, having the highest enzymatic ...

Hypercapnia Induces Mitochondrial Adaptations and Alters Glutamine Metabolism to Drive a Distinct Metabolic Phenotype in Monocytes

Immunology &Cell Biology, EarlyView.
Elevated CO2 (hypercapnia) is a feature of serious lung diseases, for example COPD and contributes to poor patient prognosis through modulation of immune cell function. Here we employ state‐of‐the art metabolomic and isotope tracing approaches to reveal CO2‐dependent mitochondrial alterations linked to suppressed ATP, proline and glutamate levels in ...

Identification of Inhibitors of Phosphate-activated Glutaminase for the Pharmacotherapy of Schizophrenia [PDF]

, 2020
In the brain, phosphate-activated glutaminase catalyzes the recycling of glutamine back to glutamate for excitatory neurotransmission. In mice, genetic knockdown of phosphate-activated glutaminase has been shown to confer resilience to schizophrenia-like

Epigenomic Cascades Across Organs in Metabolic Dysfunction–Associated Steatotic Liver Disease: New Therapeutic Horizons

Obesity Reviews, EarlyView.
ABSTRACT Metabolic dysfunction–associated steatotic liver disease (MASLD) is the most common chronic liver disorder worldwide, affecting approximately one‐third of the population and increasing the risk of severe hepatic and cardiovascular complications.

Metabolic reprogramming of the immune response in periodontitis

Periodontology 2000, EarlyView.
Abstract Objective Periodontitis, a highly prevalent chronic inflammatory disease, is characterized by the progressive destruction of the tooth‐supporting tissues, ultimately causing tooth loss. In recent years, the emerging field of immunometabolism has revealed that immune cell function is tightly regulated by intracellular metabolic pathways that ...

Hypoxia‐induced vulnerability of the somatosensory nervous system

The Journal of Physiology, EarlyView.
Abstract figure legend Sensory neurons are highly energy dependent and rely on sufficient oxygen availability to maintain metabolic stability and effective neurocommunication. Within the somatosensory system, even modest reductions in tissue oxygen tension impair neuronal respiration, forcing a shift toward less efficient metabolic pathways that ...
