Project description:With the increasing demand for donkey production, there has been a growing focus on the breeding of donkeys. However, our current understanding of the mechanisms underlying spermatogenesis and maturation in donkeys during reproduction remains limited.In this study, we constructed a single-cell RNA dataset to study the single-cell landscape of donkey spermatogenesis and maturation. This method allows us to analyze the cell composition in testicular and epididymal tissue, providing insights into the changes that occur during donkey spermatogenesis and maturation. In addition, different gene expression signatures associated with various spermatogenic cell types were found

Project description:Background: milk is considered an important source of bioactive peptides, which can be produced by endogenous or starter bacteria, such as lactic acid bacteria, that are considered effective and safe producers of food-grade bioactive peptides. Among the various types of milk, donkey milk has been gaining more and more attention for its nutraceutical properties. Methods: Lactobacillus rhamnosus 17D10 and Lactococcus lactis subsp. cremoris 40FEL3 were selected for their ability to produce peptides from donkey milk. The endogenous peptides and those obtained after bacterial fermentation were assayed for their antioxidant, antibacterial and antiviral activities. The peptide mixtures were characterized by means of LC-MS/MS, and then analyzed in silico using the Milk Bioactive Peptide DataBase. Results: the peptides produced by the two selected bacteria enhanced the antioxidant activity and reduced E. coli growth. Only the peptides produced by L. rhamnosus 17D10 were able to reduce S. aureus growth. All the peptide mixtures were able to inhibit the replication of HSV-1 by more than 50%. Seventeen peptides were found to have 60% sequence similarity with already known bioactive peptides. Conclusion: a lactic acid bacterium fermentation process is able to enhance the value of donkey milk through bioactivities that are important for human health.

Project description:The large-scale application of genomic and metagenomic sequencing technologies has yielded a number of insights about the metabolic potential of symbiotic human gut microbes. Bacteria that colonize the mucosal layer that overlies the gut epithelium have access to highly-sulfated polysaccharides (i.e., mucin oligosaccharides and glycosaminoglycans), which they could potentially forage as nutrient sources. To be active, sulfatases must undergo a critical post-translational modification catalyzed in anaerobic bacteria by the AdoMet enzyme anSME (anaerobic Sulfatase-Maturating Enzyme). In the present study, we have tested the role of this pathway in the prominent gut symbiont Bacteroides thetaiotaomicron, which possesses more predicted sulfatases (28) than in the human genome and a single predicted anSME. In vitro studies revealed that deletion of its anSME (BT0238) results in loss of sulfatase activity and impaired ability to use sulfated polysaccharides as carbon sources. Co-colonization of germ-free animals with both isogenic strains, or invasion experiments involving the introduction of one then the other strain, established that anSME activity and the sulfatases that are activated via this pathway, are important fitness factors for B. thetaiotaomicron, especially when mice are fed a simple sugar diet that requires this saccharolytic bacterium to adaptively forage on host glycans as nutrients. Whole genome transcriptional profiling of wild-type and the anSME mutant in vivo revealed that loss of this enzyme alters expression of genes involved in mucin utilization and that this disrupted ability to access mucosal glycans likely underlies the observed dramatic colonization defect. Comparative genomic analysis reveals that 100% of 46 fully sequenced human gut Bacteroidetes contain homologs of BT0238 and genes encoding sulfatases, suggesting that this is an important and evolutionarily conserved feature. Three replicate samples from 4 different biological treatment groups: 1. Wild-type B. thetaiotaomicron from the cecum of gnotobiotic mice fed a simple-sugar diet; 2. chuR mutant B. thetaiotaomicron from the cecum of gnotobiotic mice fed a simple-sugar diet; 3. Wild-type B. thetaiotaomicron from the cecum of gnotobiotic mice fed a plant-rich diet; 4. chuR mutant B. thetaiotaomicron from the cecum of gnotobiotic mice fed a plant-rich diet.

Project description:We investigated the biological effects of ZEA exposure on donkey granulosa cells by using RNA-seq analysis. ZEA at 10 and 30 μM were administered to granulosa cells within 72 hours of in vitro culture. ZEA at 10 μM significantly altered the tumorigenesis associated genes in donkey granulosa cells. Exposure to 10 and 30 μM ZEA treatment significantly reduced mRNA expression of PTEN, TGFβ, ATM, and CDK2 genes, particularly, the ZEA treatment significantly increased the expression of PI3K and AKT genes. Furthermore, immunofluorescence, RT-qPCR, and Western blot analysis verified the gene expression of ZEA-exposed granulosa cells. Collectively, these results demonstrated the deleterious effect of ZEA exposure on the induction of ovarian cancer related genes via the PTEN/PI3K/AKT signaling pathway in donkey granulosa cells in vitro.

Project description:In this study, 3,869 donkey skeletal muscle lncRNAs were identified using RNA-Seq along with a stringent screening procedure in the longissimus dorsi (LD) and gluteal (G) muscles. These lncRNAs share many characteristics with other mammalian lncRNAs, such as shorter open reading frames (ORFs) and lower expression levels than mRNAs. Furthermore, in pairwise comparisons between libraries of the same stage for two genetic types of male Dezhou donkey, 73 differentially expressed lncRNAs were common to all muscle tissues.

Project description:We examined the growth curve, cell cycle, apoptosis and glycolysis of donkey, horse and mule adult fibroblasts (DAFs, HAFs and MAFs), which indicated there are differences in cell proliferation and metabolism. We also derived mule, donkey and horse iPSCs from their respective adult fibroblasts by piggyBac transposition, and we found the induced reprogramming efficiency of mule iPSCs was significantly higher than donkey and horse iPSCs (78.3% vs 58.2% vs 47.9%). miPSCs, diPSCs and hiPSCs all expressed high levels of key endogenous pluripotency genes such as Oct4, Sox2 and Nanog, propagated robustly in single cell passaging and miPSCs were found to proliferated significantly faster than diPSCs and hiPSCs. Furthermore, miPSCs/MAFs clustered closer to diPSCs/DAFs than to hiPSCs/HAFs by RNA-seq. The establishment of miPSCs provide unique experimental materials for further investigation of understanding the “heterosis” and reproductive isolation during speciation.
