Elucidating Immune Cell Mediated Causal Pathways Linking Blood Metabolites to Major Depressive Disorder: A Mediation Mendelian Randomization Analysis

Brain and Behavior, Volume 16, Issue 6, June 2026.
Our integrative Mendelian randomization framework revealed that specific circulating metabolites exert causal effects on major depressive disorder, partly through immune‐cell–mediated pathways. These findings highlight metabolite–immune interactions as potential mechanistic targets for MDD prevention and therapy.

Characterisation of putrescine uptake by cultured adult mouse hepatocytes

, 1990
Uptake of polyamines by cultured cells has been shown to be influenced by growth rate and/or differentiation. In this study, we have investigated whether the fully differentiated, non-proliferating adult mouse hepatocyte is capable of accumulating ...

Regulation of Quality and Phenolic Metabolism in Apricot Fruit by Postharvest Salicylic Acid and Putrescine Applications

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
This study evaluated the effects of salicylic acid and putrescine (1 mM) treatments on the quality and biochemical properties of apricot fruit during 30 days of cold storage. Although weight loss and decay increased during storage, applications significantly reduced these negative effects.

Engineering tunable biosensors for monitoring putrescine in Escherichia coli

, 2018
Biosensors can be a powerful tool for real-time monitoring of specific small molecules and for precise control of gene expression in biological systems. Thus, biosensors have attracted much attention for monitoring increasing number of molecules. However,

Main effects of ascorbic acid levels and organic acid type on physicochemical properties, microbial populations, texture, and biogenic amine formation in sucuk

Journal of the Science of Food and Agriculture, Volume 106, Issue 8, Page 4942-4950, June 2026.
Abstract BACKGROUND Sucuk is a traditional Turkish dry fermented sausage, the quality and safety of which depend on physicochemical, microbiological, and biochemical changes during fermentation and ripening. Organic acids, their salts, and antioxidants such as ascorbic acid (AA) are widely used in fermented meat products; however, information about ...

Crystal structure of putrescine aspartic acid complex

, 1990
Polyamines, putrescine, spermidine and spermine are ubiquitous biogenic cations believed to be important for a variety of cellular processes. In order to obtain structural information on the interaction of these amines with other biomolecules, the ...

Interplay of Diet, Heat Stress, and the Microbiome Shapes Health and Escape Behaviour in Amphibian Larvae

Environmental Microbiology, Volume 28, Issue 6, June 2026.
Diet and temperature jointly shape the gut microbiome and host performance in amphibian larvae. In a multifactorial experiment with Rana temporaria, diet quality, rearing temperature, and heatwave exposure altered microbial communities and predicted metabolic pathways, while host health remained largely stable, suggesting microbiome plasticity and ...

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

Plant Biotechnology Journal, Volume 24, Issue 6, Page 4139-4158, June 2026.
BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Putrescine priming effects on chlorophyll fluorescence, antioxidant enzyme activity, and primary metabolite accumulation in maize seedlings under water deficit

Biologia Plantarum
This study aimed to evaluate the effect of putrescine priming on the initial growth, chlorophyll fluorescence, primary metabolites accumulation, and antioxidant enzyme activities in two maize hybrids with contrasting drought tolerances. Seeds of Zea mays
