Project description:Purpose: RNA-Seq has become a powerful tool for investigating transcriptional profiles in gene expression analysis, which would help to reveal the molecular mechanism of Clostridium perfringens type C infecting the piglets. In this study, we analyzed miRNA profiles of the spleen of piglets caused by Clostridium perfringens type C. Methods: 30 normal 7-day-old piglets (Y x L), without infecting Clostridium perfringens type C, Escherichia coli and Salmonella, were selected as experimental subjects. 25 piglets were randomly selected as the experimental group, which were disposed once a day for 5 days. Each piglet was dosed with 1 ml of bouillon culture-medium inoculated Clostridium perfringens type C at 37℃ for 16h, which approximate to 1 x109 CFU per ml. Then, 5 piglets were randomly selected as the control group (SC), which were taken the equal volume medium for 5 days.Based on total diarrhea scores, 25 piglets were ranked from high to low. The top and last five piglet were considered as sensitive group (SS) and resistant group (SR), respectively. Finally, spleen were collected and sequenced for miRNA. Result: 88 differentially expressed miRNAs were found. KEGG pathway analysis for target genes revealed that these miRNAs were involved in MAPK signaling pathway, mTOR signaling pathway, FoxO signaling pathway, p53 signaling pathway and ECM-receptor interaction. And 4 miRNAs (miR-133b, miR-532-3p, miR-339-5p and miR-331-3p) of closely related to piglets resistance to C. perfringens type C were obtained. The expression correlation analysis between these miRNAs and target genes revealed that the expression of miR-133b and miR-532-3p had negative correlation with their target NFATC4, miR-339-5p had negative correlation with target HTRA3, and miR-339-5p and miR-331-3p had negative correlation with target TNFAIP8L2 in spleen, suggesting that miR-133b and miR-532-3p targeting to NFATC4, miR-339-5p targeting to HTRA3, and miR-339-5p and miR-331-3p targeting to TNFAIP8L2 were probably involved in piglet resisting C. perfringens type C. Conclusions:The results will provide value resources for better understanding of the genetic basis of C. perfringens type C resistance in piglet and lays a new foundation for identifying novel markers of C. perfringens type C resistance.

Project description:Purpose: RNA-Seq has become a powerful tool for investigating transcriptional profiles in gene expression analysis, which would help to reveal the molecular mechanism of Clostridium perfringens type C infecting the piglets. In this study, we analyzed the transcriptome profiles of the spleen of piglets caused by Clostridium perfringens type Cens type C. Methods: 30 normal 7-day-old piglets (Y x L), without infecting Clostridium perfringens type C, Escherichia coli and Salmonella, were selected as experimental subjects. 25 piglets were randomly selected as the experimental group, which were disposed once a day for 5 days. Each piglet was dosed with 1 ml of bouillon culture-medium inoculated Clostridium perfringens type C at 37℃ for 16h, which approximate to 1 x109 CFU per ml. Then, 5 piglets were randomly selected as the control group (SC), which were taken the equal volume medium for 5 days.Based on total diarrhea scores, 25 piglets were ranked from high to low. The top and last five piglet were considered as sensitive group (SS) and resistant group (SR), respectively. Finally, spleen were collected and sequenced for lncRNA and mRNA. Results: RNA libraries constructed from spleen of piglets caused by Clostridium perfringens type C were sequenced. A total of 1,450,292,484 clean reads were generated. Among them, 2056 novel lncRNA transcripts corresponding to 1561 lncRNA genes were identified, including 1811 intergenic lncRNAs and 245 anti-sense lncRNAs. The identified spleen lncRNAs shared some characteristics, such as fewer exons and shorter length, with the lncRNAs in other animal. Notably, in pairwise comparisons between the libraries of spleen tissue at the different group, a total of 247 lncRNA and 2170 mRNA were differentially expressed (P < 0.05). Function analyses indicated that these differentially expressed lncRNAs and mRNAs play roles in defensing Clostridium perfringens type C, which were enriched in immune-related biological processes, such as the antigen processing and presentation, TNF signaling pathway, NF-kappa B signaling pathway, B cell receptor signaling pathway and MAPK signaling pathway. Conclusions: This study provides the information of spleen-related lncRNAs in swine diarrhea with Clostridium perfringens type C. We also analyzed all lncRNA’s genomic feature and expression. Bioinformatic analysis indicates that some lncRNAs participated in important biological processes associated with defeasing Clostridium perfringens type C, such as antigen processing and presentation, the MHC protein complex and regulation of autophagy.

Project description:Purpose: RNA-Seq has become a powerful tool for investigating transcriptional profiles in gene expression analysis, which would help to reveal the molecular mechanism of Clostridium perfringens type C infecting the piglets. In this study, we analyzed miRNA profiles of the ileum of piglets caused by Clostridium perfringens type C. Methods: 30 normal 7-day-old piglets (Y x L), without infecting Clostridium perfringens type C, Escherichia coli and Salmonella, were selected as experimental subjects. 25 piglets were randomly selected as the experimental group, which were disposed once a day for 5 days. Each piglet was dosed with 1 ml of bouillon culture-medium inoculated Clostridium perfringens type C at 37℃ for 16h, which approximate to 1 x10e9 CFU per ml. Then, 5 piglets were randomly selected as the control group (IC), which were taken the equal volume medium for 5 days.Based on total diarrhea scores, 25 piglets were ranked from high to low. The top and last five piglet were considered as sensitive group (IS) and resistant group (IR), respectively. Finally, ileum were collected and sequenced for miRNA. Result: 53 differentially expressed miRNAs were found. KEGG pathway analysis for target genes revealed that these miRNAs were involved in ErbB signaling pathway, MAPK signaling pathway, Jak-STAT signaling pathway and Wnt signaling pathway. The expression correlation analysis between miRNAs and target genes revealed that the expression of miR-7134-5p had negative correlation with target NFATC4, miR-500 had negative correlation with target ELK1, HSPA2 and IL7R, and miR-92b-3p had negative correlation with target CLCF1 in ileum of IR vs IS group, suggesting that miR-7134-5p targeting to NFATC4, miR-500 targeting to ELK1, HSPA2 and IL7R, and miR-92b-3p targeting to CLCF1 were probably involved in piglet resisting C. perfringens type C. Conclusions: The results will provide value resources for better understanding of the genetic basis of C. perfringens type C resistance in piglet and lays a new foundation for identifying novel markers of C. perfringens type C resistance

Project description:MicroRNAs (miRNAs) in serum are very stable and specific. Moreover, serum miRNAs are non-destructive and convenient. Studies have shown that the changes of serum miRNAs are closely relative to the pathological stresses and diseases. Our previous studies suggested that weaning stress induced the abnormal miRNA transcriptome in the intestine of piglets. In this project, we will further screen serum miRNA expression in piglets induced by weaning stress using miRNA microarray. Microarrays containing 422 porcine unique miRNA probes were employed to identify differences in the expression patterns of the miRNA between weaning piglets at 4 d after weaning and suckling piglets at the same days old. A total of 115 differentally expressed miRNAs were found,therein 63 miRNAs upregulated and 52 miRNA downregulated; 64 miRNAs are statistically significant but have low signals (signal < 500);122 miRNAs are not statistically significant (p > 0.01); the remaining 132 miRNAs have not detected signals.

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..

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.
