Project description:small RNA seqencing of pig small inteseine cells samples from different groups in different generations to search for weaning effect on gene expression.
Project description:Age- and lactocrine-sensitive elements of the neonatal porcine uterine developmental program are undefined. Here, effects of age and nursing for 48 h from birth (postnatal day = [PND] 0) on the uterine transcriptome at PND 2 were identified using RNA sequencing. Pig uterine tissues were obtained from neonatal gilts (n = 4/group) within 1 h of birth [postnatal day (PND) 0], or 48 h after nursing ad libitum (PND 2N), or feeding a commercial milk replacer (PND 2R).

Project description:The objective of this experiment was to use transcriptional profiling of skeletal muscle and adipose tissue to develop a better understanding of the metabolic basis for poor weaned-pig transition. A total of 1,054 pigs were reared in commercial conditions and weighed at birth, weaning, and 3 weeks post- weaning. Transition average daily gain (tADG) was calculated as the average daily gain for the 3-week period post-weaning. Nine pigs from each of the lowest 10th percentile (low tADG) and the 60th-70th percentile (high tADG) were harvested at 3 weeks post-weaning. Differential expression analysis was conduced in both tissues using RNA-Seq methodology

Project description: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.
