The Oral‐Gut Axis: Bidirectional Interactions Between Microbiome and Diseases

Journal of Periodontal Research, EarlyView.
This study aims to summarize the mechanisms underlying ectopic colonization of the gut by oral pathobionts and the microbial and host factors that regulate this process. ABSTRACT Increased colonization of typically oral microorganisms is frequently observed in the gut mucosa or lumen of individuals with gastrointestinal disorders, including patients ...

Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present‐day

Purification and characterization of putrescine synthase from cucumber seedlings. A multifunctional enzyme involved in putrescine biosynthesis [PDF]

, 1986
The multifunctional enzyme, putrescine synthase has been purified fromCucumis sativus and characterized. This enzyme harbours agmatine iminohydrolase, ornithine transcarbamylase, putrescine transcarbamylase and carbamate kinase activities, whose ...

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

Plant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Putrescine treatment has a higher effect on 5mC DNA methylation profile of wheat leaves under white than under blue light conditions

Scientific Reports
Polyamines play a pivotal role in plant growth and development by modulating primary metabolism and gene expression patterns. However, their regulatory effect on epigenetics is still not clear.

Satellite Glial Cells Synthesize and Release GABA to Activate Extrasynaptic GABAA Receptors That Modulate Dorsal Root Ganglia Neuron Excitability

Glia, Volume 74, Issue 9, September 2026.
Mechanism of synthesis, release, receptor activation, uptake, and degradation of GABA in dorsal root ganglia (DRG). Left: GABA is synthesized from putrescine in satellite glial cells (SGCs). After being released by Best1 channel, it activates GABAA receptors in sensory neurons, producing a chloride current.

Systemic administration of putrescine induces GABA-like behaviors in rats [PDF]

, 1982
Putrescine is a polyamine with multiple roles in cellular metabolism. It is also a minor precursor of the inhibitory neurotransmitter, gamma-aminobutyric acid (GABA).

Putrescine reverses aconitine-induced arrhythmia in rats [PDF]

, 1989
Putrescine, (150-300 mg kg-1 i.v.) injected into anaesthetized rats reversed aconitine-induced arrhythmia and restored sinus rhythm. In the same experimental model, quinidine and lignocaine had a transient therapeutic effect, procainamide was practically

Effects of Exogenous Monosodium Glutamate on GABA Accumulation and Volatile/Nonvolatile Metabolites in Black Highland Barley

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Overview of MSG‐assisted GABA enrichment and associated changes in amino acid, fatty acid, and volatile metabolite profiles in germinated black highland barley. ABSTRACT γ‐Aminobutyric acid (GABA) is a functional amino acid with multiple health benefits; however, the mechanism of its enrichment in black highland barley, particularly through precursor ...
