Intestinal gene expression analysis in response to maternal dietary resveratrol supplementation in pig

ABSTRACT: Early weaning commonly results in gastrointestinal disorders, inflammation and diarrhea in infants and young animals. Resveratrol, a plant phenol, affords protection against inflammation and cancer.A porcine model was used to investigate the effects of maternal resveratrol supplementation on diarrhea, intestinal inflammation and intestinal morphology in offspring during weaning. The intestinal gene expression was measureed by RNA sequencing (RNA-seq) analysis. Results that weaning-associated intestinal inflammation and diarrhea in pig offspring were alleviated and intestinal morphology was improved by maternal resveratrol supplementation. In weaning piglets (21-day-old), RNA-seq showed that differentially expressed genes (DEGs) were enriched for T cell receptor, primary immunodeficiency, mitogen-activated protein kinase (MAPK) and Ras signaling pathway. In post-weaning piglets (28-day-old), RNA-seq showed that DEGs were enriched in the cytokine-cytokine receptor interaction pathway and pathways related to metabolism. This study provided insight into molecular mechanisms underlying the effects of maternal dietary resveratrol.

Project description:BACKGROUND: Diarrhea is common in infants, particularly, children less than 2 years old. Intractable or protracted infancy diarrhea is typically associated with feeding intolerance and malabsorption that is lethal for newborns. This study aimed to evaluate the effectiveness of baizhu shaoyao decoction in reducing functional diarrhea induced by weaning stress, while also delving into its potential mechanisms of action.RESULTS: Piglets were allocated into 5 groups, with each group receiving designated medication for a continuous 14-day period: control, zaohu powder, as well as low-, medium- and high-dose baizhu shaoyao decoction groups (n = 6 piglets per group). To identify diarrhea-related biomarkers, microbial communities, functions and metabolites were compared between the early-weaned piglets (control group) and those treated with 1.28 g/kg baizhu shaoyao decoction (medium-dose baizhu shaoyao decoction group). Our findings revealed significant shifts in microbial composition, function and metabolic profiles in piglets from the medium-dose baizhu shaoyao decoction group, intricately associated with the host's diarrhea status. Furthermore, carbohydrate metabolism and biosynthesis, lipid and amino acid metabolism, glycan activity and carbohydrate digestive enzymes exhibited downregulation in piglets of the medium-dose baizhu shaoyao decoction group compared to those in the control group. Transcriptome analysis highlighted the pivotal role of the FoxO1/3 transcription factor in mitigating weaning stress, particularly through the augmentation of CD4+/CD8+ T cell proportions. Our findings underscored that baizhu shaoyao decoction's therapeutic effects on weaning stress involve intestinal barrier restoration, modulation of brain-gut peptide expression and a reduction in mast-cell activity in the ileum.CONCLUSIONS: The key metabolites (chenodeoxycholyglycine, chenodeoxycholyltaurine, dinoprost, chenodeoxyglycocholic acid, glycochenodeoxycholic acid, glycocholic acid, N-choloylglycine, 5-trans-PGE2, Pregnanediol 3-O-glucuronide, spermidine and spermine) exhibited strong correlations with the abundance of Clostridia_bacterium and Lachnospiraceae_bacterium, emphasizing the significance of Clostridia_bacterium and Lachnospiraceae_bacterium in gut metabolism and function. Besides, this study suggests the potential efficacy of baizhu shaoyao decoction in addressing early post-weaning stress-induced diarrhea in infants, showcasing promising prospects for translational and clinical applications.
