Project description:The Chinese forest musk deer (FMD; Moschus berezovskii) is an endangered artiodactyl mammal. Musk secreted by the musk gland of male FMD has extremely high economic and medicinal value. At present, little is known about the development of musk glands and the molecular mechanism of musk secretion. In the present research, using snRNA-seq and snATAC-seq association analysis performed on musk glands of forest musk deer, coupled with several bioinformatics analyses, the dynamic transcriptional cell atlas of musk gland development was revealed and the genes and transcription factors affecting musk secretion were determined. Based on uniform manifold approximation and projection (UMAP) analysis, we identified 12 cell types from musk glands, including two different acinar cells (clusters 0 and 10). In addition, the expression of core target genes and core transcription factors was verified by fluorescence in situ hybridization and immunohistochemistry. Combined with weighted gene co-expression network analysis (WGCNA), we obtained a deeper biological understanding of the relationship between core transcription factors, differentially expressed genes and musk secretion related pathways. This study lays a foundation for improving musk yield and meeting market demand. In the meantime, it also contributes to reducing the hunting and poaching of wild forest musk deer, protecting forest musk deer resources and maintaining ecological balance.

Project description:Pneumonia can seriously threaten the life of forest musk deer (an endangered species). To gain a comprehensive understanding of pneumonia pathogenesis in forest musk deer, iTRAQ-based proteomics analysis was performed in diseased (Phe group) and normal (Ctrl group) lung tissues of forest musk deer that died of pneumonia. Results showed that 355 proteins were differentially expressed (fold change ≥ 1.2 and Q < 0.05) in Phe vs Ctrl experiments. GO/KEGG annotation and enrichment analyses showed that dysregulated proteins might play vital roles in bacterial infection and immunity. Given the close association of bacterial infection and pneumonia, 32 dysregulated proteins related to Staphylococcus aureus infection, bacterial invasion of epithelial cells, and pathogenic Escherichia coli infection were screened out. Among these 32 proteins, 13 proteins were mapped to the bovine genome. Given the close phylogenetic relationships of forest musk deer and bovine, the protein-protein interaction networks of the above-ment

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.

Project description:To characterize the effect of microbiota on global gene expression in the distal small intestine during postnatal gut development we employed mouse models with experimental colonization by intestinal microbiota. Using microarray analysis to assess global gene expression in ileal mucosa at the critical stage of intestinal development /maturation associated with weaning, and asking how expression is affected by microbial colonization In the study presented here, preweaned and postweaned GF, SPF mouse small intestinal total RNAs were used. Also, 3-week-old gnotobiotic mouse as well as GF mouse small intestinal RNAs were used.
