The aryl hydrocarbon receptor (AhR) and the peroxisome proliferator-activated receptor γ (PPARγ) are ligand-activated transcription factors that have in recent years been investigated for their anti-inflammatory properties for treatment of inflammatory bowel diseases (IBDs). These are globally prevalent chronic maladies of the gut that lack cost-efficient therapeutical options capable of inducing long-term remission. In the present study, we used an in vitro Transwell co-culture model composed of Caco-2 epithelial cells in the apical compartment and lipopolysaccharide-treated (LPS) THP-1 macrophages in the basolateral compartment.

The SWI/SNF (SWItch/Sucrose Non-Fermentable) chromatin remodeling complex is involved in various aspects of plant development and stress responses. Here, we investigated the role of BRM (BRAHMA), a core catalytic subunit of the SWI/SNF complex, in Arabidopsis thaliana seed biology. brm-3 seeds exhibited enlarged size, reduced yield, increased longevity, and enhanced secondary dormancy, but did not show changes in primary dormancy or salt tolerance.

Introduction: Plant hormonal mutants, which do not produce or are insensitive to hormones, are often affected in their growth and development, but other metabolic rearrangements might be involved. A trade-off between growth and stress response is necessary for the plant survival.

Objectives: Here, we explore the metabolic profile and the pathogen resistance of a brassinosteroid-insensitive Hordeum vulgare L.

Plants and algae play a crucial role in the earth's ecosystems. Through photosynthesis they convert light energy into chemical energy, capture CO2 and produce oxygen and energy-rich organic compounds. Photosynthetic organisms are primary producers and synthesize the essential omega 3 and omega 6 fatty acids.

Article Synopsis
  • - The study focuses on an Arabidopsis mutant that has a defect in the sterolmethyltransferase2 (SMT2) enzyme, leading to significant growth issues and a loss of specific sterols, indicating the unique function of C-24 ethyl sterols in growth.
  • - Fluorescent labeling of sterol biosynthetic enzymes showed that SMT2-GFP is located in the endoplasmic reticulum during interphase but relocates to the division plane during cell division, revealing that this movement is not linked to the transport of cytokinetic vesicles.
  • - The abnormal division processes are accompanied by poor cytoskeletal organization and a failure to establish proper cell wall structures in daughter cells, suggesting that C-24
