Cultivation‐Based Detection of a Novel High‐GC Nitrospira Derived From the Argentinian Copahue Volcano Area

Environmental Microbiology, Volume 28, Issue 4, April 2026.
In this cultivation‐based study, two novel moderately thermophilic Nitrospira enrichments were obtained from the geothermal field Las Máquinas in the Neuquén Province, Argentina. Both nitrite oxidizers, belonging to lineage V or the novel taxonomic lineage VIII, contain quorum‐sensing genes and a high genome GC content of 60.6% and 69.4%.

The return of metabolism: biochemistry and physiology of glycolysis

Biological Reviews, Volume 101, Issue 2, Page 751-803, April 2026.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Molecular evolution of the polyamine oxidase gene family in Metazoa

BMC Evolutionary Biology, 2012
Background Polyamine oxidase enzymes catalyze the oxidation of polyamines and acetylpolyamines. Since polyamines are basic regulators of cell growth and proliferation, their homeostasis is crucial for cell life.

Putrescine, spermidine, and spermine play distinct roles in rice salt tolerance

Journal of Integrative Agriculture, 2020
Polyamines (PAs) play diverse roles in plant growth and development, as well as responses to environmental stimuli. In this study, the effects of PAs on rice salt tolerance were investigated.

G protein-coupled receptor kinase-2 (GRK-2) regulates serotonin metabolism through the monoamine oxidase AMX-2 in Caenorhabditis elegans. [PDF]

, 2017
G protein-coupled receptors (GPCRs) regulate many animal behaviors. GPCR signaling is mediated by agonist-promoted interactions of GPCRs with heterotrimeric G proteins, GPCR kinases (GRKs), and arrestins.

The Crosstalk Mechanisms Between Ferroptosis and Pyroptosis and Their Applications in Diseases: From Molecular Networks to Clinical Strategies

Journal of Cellular and Molecular Medicine, Volume 30, Issue 8, April 2026.
ABSTRACT Ferroptosis and pyroptosis are two distinct forms of regulated cell death that play crucial roles in cancer, neurodegeneration, and inflammatory diseases. Ferroptosis is characterised by iron‐dependent lipid peroxidation, while pyroptosis is an inflammatory cell death mediated by gasdermin proteins.

Stimulation of antioxidative enzymes and polyamines during stripe rust disease of wheat

Biologia Plantarum, 2010
Content of polyamines and activities of antioxidative enzymes in response to stripe rust disease caused by Puccinia striiformis have been studied in two wheat (Triticum aestivum L.) cultivars PBW 343 (resistant) and HD 2329 (susceptible).

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the risk of food poisoning due to the presence of biogenic amines in meals made from chicken meat consumed by children under 3 years of age

Food Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Biogenic amines are low molecular weight organic bases that come from the enzymatic decarboxylation of amino acids. They are present in many types of food, with the highest concentrations usually found in fish and their derived products, as well as in beverages and fermented foods of plant, meat and dairy origin.

Effect of Nitric Oxide Fumigation Combined with Hypobaric Treatment on the Postharvest Quality and Metabolism of Polyamines and Glutathione in Xiaobai Apricots [PDF]

Shipin Kexue
To investigate the regulatory effect of nitric oxide (NO) fumigation combined with hypobaric treatment (HYT) on the postharvest quality of Xiaobai apricots, ‘Luntai’ apricots were treated with exogenous NO under hypobaric conditions (HYT + NO).
