Project description:Background: The number of red blood cells (RBCs) increases significantly in response to high-altitude hypoxic environments, and the RBC microRNA (miRNA) expression pattern is similar to that in whole blood. Studies have shown that miRNA in plasma can act as a circulating hypoxia-associated marker, but the effect of a high-altitude hypoxic environment on RBC-derived miRNAs has not yet been reported. Methods: Blood samples were collected from 20 Han Chinese individuals residing at 500 m (Sichuan Han), 10 migrant Han Chinese citizens residing at 3658 m (Tibet Han) and 12 native Tibetans, and RBC indices measurements and miRNA sequencing analyses were performed for the three sample groups. The levels of some markedly altered miRNAs at high altitude were subsequently measured from 5 randomly selected samples of each group by real-time PCR. Bioinformatic analyses was performed to determine the potential target genes of selected hypoxia-associated miRNAs. Results: Marked changes of several RBC indices were observed among the Tibet Han population, the Tibetan population and the Sichuan Han population. A total of 516 miRNAs derived from RBCs were initially identified by miRNA sequencing in the three sample groups. Compared with the Sichuan Han population, 49 miRNAs were differentially expressed in the Tibet Han population (17 upregulated and 32 downregulated). 12 upregulated and 21 downregulated miRNAs were observed in the Tibetan population compared with the Sichuan Han population. A total of 40 RBC miRNAs were differentially expressed in the Tibetan population (15 upregulated and 25 downregulated) compared with the Tibet Han population. Two significantly altered miRNAs with the highest expression levels (miRNA-144-5p and miR-30b-5p) were selected for real-time PCR analysis, and the results were consistent with those of miRNA sequencing. Furthermore, bioinformatic analyses showed that some potential target genes of miR-144-5p and miR-30b-5p are involved in the erythroid- hypoxia-, and nitric oxide (NO)-related signaling pathways in response to hypoxia. Conclusion: Our findings provide clear evidence, for the first time, that a high-altitude hypoxic environment significantly affects human RBC miRNA profiles.

Project description:Primary objectives: The primary objective is to investigate circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).

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: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.

Project description:A comprehensive glycosylation profile of donkey lactoferrin, isolated by ion exchange chromatography from an individual milk sample, was obtained by means of chymotryptic digestion, TiO2 and HILIC enrichment, reversed-phase high performance liquid chromatography, electrospray mass spectrometry, and high collision dissociation fragmentation. The results obtained allowed the identification of 26 different glycan structures, including high mannose, complex and hybrid N-glycans, linked to the protein backbone via an amide bond to asparagine residues located at the positions 137, 281 and 476. Altogether, the N-glycan structures determined revealed that in donkey milk lactoferrin most of the N-glycans identified are neutral complex/hybrid. Actually, 10 neutral non-fucosylated complex/hybrid N-glycans and 4 neutral fucosylated complex/hybrid N-glycans were found. In addition, 2 high mannose N-glycans, 4 sialylated fucosylated complex/hybrid N-glycans and 6 sialylated non-fucosylatedN-glycans, one of which containing N-glycolylneuramin acid (Neu5Gc), were found. A comparison of the glycosylation profile of donkey milk lactoferrin with respect to that of human, bovine and goat milk lactoferrin is reported.
