Project description:We sequenced the miRNAs in the liver tissues of goats to further enrich and elucidate the miRNA expression profile in their physiological cycle. The liver tissues were procured at 5-time points from the Laiwu black goats of 1 day, 2 weeks, 4 weeks, 8 weeks, and 12 weeks of age, respectively with 5 goats per time point, for a total of 25 goats. This study identified 1255 miRNAs.
Project description:9 submandibular gland tissue samples were collected from goats in 1-month-old, 12-month-old and 24-month-old groups (3 samples from each group), and high-throughput transcriptome sequencing was conducted on these samples.
Project description:To reveal the transcriptomic changes of hypothalamic tissue in goats from birth to sexual maturity, we performed transcriptome sequencing of Jining Grey Goat hypothalamic tissues at four developmental stages after birth. A total of 20 libraries from four different development stages (5 goats per stage) were successfully constructed, and the corresponding mRNA and lncRNA expression profile were obtained.
Project description:In order to reveal the changes of microRNA spectrum in hypothalamus tissues of goats from birth to sexual maturity, smallRNA sequencing was performed on hypothalamus tissues of Jining grey goats at 4 developmental stages after birth. Twenty libraries from 4 different developmental stages (5 goats per stage) were successfully constructed and the corresponding miRNA expression profiles were obtained.
Project description:Management of terminal ileal Crohn's disease (CD) is difficult due to fibrotic prognosis and failure to achieve mucosal healing. A limited number of synchronous analyses have been conducted on the transcriptome and microbiome in unpaired terminal ileum tissues. Therefore, our study focused on the transcriptome and mucosal microbiome in terminal ileal tissues of CD patients with the aim of determining the role of cross-talk between the microbiome and transcriptome in the pathogenesis of terminal ileal CD. Mucosa-attached microbial communities were significantly associated with segmental inflammation status. Interaction-related transcription factors (TFs) are the panel nodes for crosstalk between the gene patterns and microbiome for terminal ileal CD. The transcriptome and microbiome in terminal ileal CD can be different related to local inflammatory status, and specific differentially expressed genes (DEGs) may be targeted for mucosal healing. TFs connect gene patterns with the microbiome by reflecting environmental stimuli and signals from microbiota.

Project description:Transportation stress causes significant changes in physiological responses in goats; however, studies exploring the transcriptome of stress are very limited. This study was conducted to analyze the transcriptome of stress and meat quality in goats using RNA-seq technology. Fifty-four male Spanish goats (8-mo old; BW = 29.7 ± 2.03 kg) were randomly subjected to one of three treatments (TRT; n = 18 goats / treatment): (i) transported for 180 min, (ii) transported for 30 min, or (iii) held in pens (control). Blood samples were collected before and after treatment for stress hormone, metabolite, and transcriptomic analysis. RNA-Seq technology was used to obtain the transcriptome profiles of blood. Analysis of physiological data using SAS showed that plasma cortisol concentrations were higher (P < 0.01) in 180 min and 30 min groups compared to the control group. A similar effect was noticed in plasma non-esterified fatty acid concentrations. Glucose concentrations were the lowest in the control group, highest in the 180 min group, and intermediate in the 30 min group (P < 0.01, while plasma creatine kinase concentrations were not significantly influenced by TRT. Neutrophil counts were higher (P < 0.01) and lymphocyte counts were lower (P < 0.01) in 180 min group compared to 30 min or control groups. The DESeq2 software identified a total of 430 DEGs for control vs. 30 min comparison, of which 127 genes were upregulated. For 180 min vs. control comparison, 741 DEGs were upregulated. Enrichment analysis of DEGs related to transportation stress through Gene Ontology and KEGG databases revealed that the DEGs related to inflammatory pathways, caspases, and apoptosis such as IL1R2, CASP14, CD14, TLR4, and MAPK14 were highly expressed in the transported group of goats compared to non-transported goats. Stress in goats leads to a sequence of events at cellular and molecular levels that causes inflammation and apoptosis and is also reflected in blood metabolites and leukocyte counts.
Project description:The mammary gland redeveloped to the pre-pregnancy state during involution, which shows that the mammary cells have the characteristics of remodeling. The rapidity and degree of mammary gland involution are different between mice and dairy livestock (dairy cows and dairy goats). However, the molecular genetic mechanism of miRNA in involution and remodeling of goat mammary gland has not yet been clarified. Therefore, this study carried out the RNA-sequencing of nonlactating mammary gland tissue of dairy goats in order to reveal the transcriptome characteristics of miRNA in nonlactating mammary tissues and clarify the molecular genetic mechanism of miRNA in mammary cell involution and remodeling.
