Single-cell RNA sequencing decipher hepatic injury in piglets with intrauterine growth restriction.

ABSTRACT: Intrauterine growth restriction (IUGR) is associated with increased relative liver weight at birth, hepatic function decline, and a higher risk for chronic liver and cardiovascular diseases in adults. Precise mechanisms of early developmental plasticity to intervene in poor fetal programming and adult disease remain largely elusive and warrant extensive research. Selecting natural piglets’ model of IUGR, using the liver as a readout and combining previous transcriptome findings, a map of cellular landscape was created to reveal a sex-dependent manner in IUGR-induced hepatic injury and its long-term functional repercussions.Here, we show data on the transcriptional profiles of 41,969 high-quality cells from normal birthweight (NBWs) and IUGR piglets (IUGRs) from hepatic tissue and demonstrated strong homology with human using human-derived liver single-cell dataset. We discovered that male liver was much more severely damaged and inflammation by IUGR than female liver at the one-week postnatal node.

Single-cell RNA sequencing decipher hepatic injury and APOA4 as a biomarker in males with intrauterine growth restriction

Project description:<p>Intrauterine growth restriction (IUGR) is associated with increased relative liver weight at birth, hepatic function decline and a higher risk for chronic liver and cardiovascular diseases in adults.

At the one-week postnatal node, we reveal that in contrast to a converting trend about an immune-adapted phenotype in female IUGRs, the more severe hepatic injury in male IUGRs is attributed to persistent inflammation caused by abnormal lipid metabolism, which disrupts the interactions of non-immune cells, resulting in impaired liver regeneration lasting into adulthood. In addition, we consider APOA4 as a new biomarker for the detection of IUGRs and discover its underlying role in hypoxic conditions. Our study opens the possibility to early therapy and screening of gender-specific hepatic injury brought on by IUGR.</p>

Proteomic analysis of liver proteome affected by intrauterine growth restriction in newborn piglets.

Project description:Intrauterine growth restriction (IUGR) impairs fetal growth and development, perturbs nutrient metabolism, and increases the risk of developing diseases in the postnatal life. However, the underlying mechanisms by which IUGR affects fetuses remain incompletely understood. Here, we applied high-throughput proteomics approach and biochemical analysis to investigate the impact of IUGR on fetal liver.

Effects of dietary fat on neurodevelopmental outcomes in normal birth weight and intrauterine growth restricted piglets

Project description:Breast milk has shown neurodevelopmental advantages compared to infant formula, especially in IUGR infants, which may relate to the fat source. This study aimed to compare neurodevelopmental outcomes in normal birth weight (NBW) and intrauterine growth restricted (IUGR) piglets fed a formula diet with either a vegetable oil (VEG) or bovine milk fat source (MILK). Results showed that total plasma lipids were increased by feeding the MILK diet. 82% and 11% of lipid species were differentially expressed between dietary groups in plasma and hippocampus, respectively, with slight agreement between the plasma and brain lipidome. The MILK diet was most effective in increasing brain lipid accretion, mainly comprising phospholipids. Absolute regional brain weights, grey and white matter volumes, and behavior and motor function scores were lower in IUGR piglets with no effects of diet. Cognitive function and gene expression profiles were similar for dietary and weight groups, and overall only minor interactive effects between diet and weight were observed. In conclusion, dietary fat source influenced the plasma and to a lesser degree the hippocampal lipidome, but was unable to improve on IUGR induced brain structural and functional impairments.

Swine inflammation and necrosis syndrome is associated with plasma metabolites and liver transcriptome in affected piglets

Project description:Swine Inflammation and Necrosis Syndrome (SINS) can lead to severe clinical signs, especially in tails, ears, teats and claws in pigs. Clinical and histopathological findings in newborn piglets with in-tact epidermis indicate a primarily endogenous etiology, and microbial-associated molecular pat-terns (MAMPs), such as lipopolysaccharide (LPS) are assumed to play a central role in the devel-opment of the syndrome. We hypothesized that swine inflammation and necrosis syndrome (SINS) is indirectly triggered by gut-derived MAMPs entering the circulatory system via the liver and thereby causing derangements on liver metabolism. To test this hypothesis, metabolomes, candidate genes of the liver and liver transcriptomes of 6 piglets with high-grade clinical signs of SINS (SINS high) were examined and compared with 6 piglets without significant signs of SINS (SINS low). Several hepatic pro-inflammatory genes and genes involved in stress response were induced in piglets of the SINS high group. The most striking finding from hepatic transcript pro-filing and bioinformatic enrichment was that the most enriched biological processes associated with the approximately 220 genes induced in the liver of the SINS high group were exclusively related to metabolic pathways, such as fatty acid metabolic process. Within the genes (≈ 390) re-pressed in the liver of the SINS high group, enriched pathways were ribosome biogenesis, RNA processing, RNA splicing, spliceosome and RNA transport. The transcriptomic findings were supported by the results of the metabolome analyses. These results provide the first evidence for the induction of an inflammatory process in the liver of piglets suffering from SINS, accompanied by lipid metabolic derangement.

Transcriptome analyses reveal metabolic syndrome of adulthood with intrauterine growth restriction in a pig model

Project description:Epidemiological data indicated intrauterine growth retardation (IUGR) is a risk factors for adult metabolic syndrome. However, the genetic mechanism underlying the phenotype in adulthood is not well characterized. Here, the present study employed adult normal and IUGR pigs as models to survey the difference of global gene expression in the liver using transcriptome sequence. The trancriptome libraries generated 104.54 gigabases data, 16,948 and 17,078 genes were expressed in normal and IUGR pigs, repectively. A total of 1,322 differentially expreesion genes (DGEs) were identified. An enrichment analysis of DGEs presented the top overrepresented GO terms and pathway were related to oxidoreductase activity, ATPase activity, amino catabolic process, glucose metabolism and Insulin signaling pathway. Finally, combined their phenotypes and gene expression patterns, we proved the adult IUGR pigs would obstruct the process of mitochondrial biogenesis and oxidative phosphorylation, which induced high oxidation press in adult IUGR. The increased gluconeogenic and decreased glycogen synthesis in liver resulted in reducing the capacity of glucose intolerance in IUGR. The decreased expression of insulin signaling genes (such as PI3K and AKT) implied a risk of diabetes in adult IUGR. Moreover, the capacity of fatty acid oxidation decreased in IUGR liver leaded to high content of triglyceride and free fatty acid in IUGR. Together, these findings provide a comprehensive understanding of the molecular mechanisms of adult IUGR pigs and valuable information for future studies of therapeutic intervention in IUGR metabolic syndrome.

Transcript profiling in the liver of piglets fed carnitine

Project description:Carnitine is a water soluble quaternary amine which is essential for normal function of all tissues. Besides improving performance characteristics of livestock animals carnitine has attracted scientific interest due to several health-related effects, like protection against neurodegeneration, mitochondrial decay, and oxidative stress, improvement of glucose tolerance and insulin sensitivity as well as reduction of hepatic steatosis. To gain insight into mechanisms through which carnitine exerts its beneficial metabolic effects, we fed piglets either a control or a carnitine supplemented diet, and analyzed the transcriptome in the liver, which plays a central role in whole body metabolism. Total RNA was isolated from pig liver samples for hybridization on Affymetrix GeneChip porcine genome arrays. Two RNA pools, each for the control group and the carnitine group, were used. Each RNA pool comprised RNA from 4 pigs.

The difference between diarrhea piglets and normal piglets

Project description:Sixty crossbred piglets (Duroc*Landrace*Yorkshire) weaned at the age of 21 days were maintained for one week and had free access to feed and water. During this week, all the piglets were scored for the severity of diarrhea. Diarrhea index was scored as follows: 1= hard feces; 2= no scours, feces of normal consistency; 3= mild scours, soft, partially formed feces; 4= moderate scours, loose, semi-liquid feces; 5= watery feces; as previously did Those piglets with a score of 4 or 5 for three continuous days were designated as diarrhea piglets, while those piglets with a score of 1 or 2 for three continuous days were designated as normal piglets..

Suckling piglets: Control vs. weaned piglets

Project description:Transcriptional profiling of 25d old piglets comparing control untreated suckling jejunum with weaned piglets' jejunum. The goal was to gain new insight into the interaction between weaning and intestinal function.A keen interest is paid in deciphering expression changes of apoptosis or cell cycle control genes. The statistical analysis of gene ontology revealed that most of these altered genes are metabolic-related enzymes and regulators which may involved in the biological regulation, developmental process, and cellular process. Weaning also causes alterations in various immune response pathways. Results likely indicate that weaning induced cell cycle arrest, enhanced apoptosis, and inhibited cell proliferation. Two-condition experiment, suckling control piglets' jejunum vs. weaned piglets' jejunum. Biological replicates: 4 control replicates, 4 weaned replicates.
