The gut microbiome organ

iMeta, Volume 5, Issue 4, August 2026.
The gut microbiome can be conceptualized as a distributed organ‐like functional system with spatially structured organization, broad biochemical capacity, and continuous bidirectional communication with the host. By transforming dietary, host‐derived, and environmental substrates into bioactive metabolites with endocrine‐like, immunomodulatory, and ...

The Dual Role of the Gut Microbiota in Cancer Chemoresistance

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Comparison between Microbiota and Cancer therapy. ABSTRACT Chemoresistance is one of the primary reasons that cancer chemotherapy fails to deliver successful treatment outcomes and contributes to poor overall survival rates for patients with cancer. New research has begun to shed light on the effects of the gut microbiome (GM).

Overexpression of wheat spermidine synthase gene enhances wheat resistance to Fusarium head blight

Phytopathology Research
Polyamines, such as putrescine, spermidine, and spermine, are crucial for plant defense against both abiotic and biotic stresses. Putrescine is also known as a significant inducer of deoxynivalenol (DON) production in Fusarium graminearum, the primary ...

The Chemical Regulatory Landscape of Biomolecular Condensates

Aggregate, Volume 7, Issue 7, July 2026.
Chemical regulation of biomolecular phase separation offers a unique opportunity to bridge molecular‐level chemistry with emergent cellular organization. Chemically informed strategies for controlling condensate condensates through chemically tractable parameters such as interaction valency, solvent quality, and molecular crowding provides a unifying ...

Enhancing Human Spermine Synthase Activity by Site Directed Mutations [PDF]

Biophysical Journal, 2013
Spermine Synthase (SMS) is an enzyme converting spermidine into spermine, both of which are polyamines controlling normal cell growth and development. Several missense mutations in human SMS (HsSMS) are known to cause Snyder-Robinson Syndrome (SRS) by either destabilizing the monomer/dimer conformation or directly affecting the hydrogen bond network in

Effect of salinity on polyamines and ethylene in Atriplex prostrata and Plantago coronopus

Biologia Plantarum, 2015
The aim of this study was to investigate the effects of salinity on germination, seedling growth, free polyamines (putrescine, spermidine, and spermine), and ethylene metabolism of two species (Atriplex prostrata Bouchér and Plantago coronopus L.) with ...

Caenorhabditis elegans and Drosophila melanogaster as Model Organisms in Biofactor Research

BioFactors, Volume 52, Issue 4, July/August 2026.
This review presents Caenorhabditis elegans and Drosophila melanogaster as powerful and ethically sound invertebrate model organisms that can be used to investigate nutritional science questions relating to biofactors. Such nutritional phenotyping studies can bridge the gap between in vitro studies and in vivo research in mammals.

Multi‐Induction Strategies in Crops: Mechanisms, Synergistic Effects, and Sustainable Applications for Enhanced Secondary Metabolite Production

Food Frontiers, Volume 7, Issue 4, July 2026.
This review analyzes single/combined abiotic (light, water, nutrients, hormones) and biotic (microbes, yeast) elicitors regulating signaling, gene expression, and metabolism to boost plant secondary metabolites. It highlights synergistic multielicitor strategies for crop quality and functional foods, while critically addressing current limitations and ...
