Stranded Total RNA-seq of whole blood cells collected from Holstein Friesian cows

ABSTRACT: Bovine mastitis is an inflammatory disease of the mammary gland with serious economic implications for dairy industries worldwide. We performed total RNA sequencing using whole blood cells collected from multiparous Holstein Friesian dairy cows with naturally occurring mastitis to investigate the changes in systemic gene expression and their association with inflammatory responses. Some related sequencing data are deposited in E-MTAB-9347 and E-MTAB-9348.

Stranded Total RNA-seq of whole blood cells collected from Holstein Friesian cows that were defined from cluster analysis as being metabolically "balanced", "imbalanced" or "other

Project description:Homeorhetic mechanisms assist dairy cows to transition from pregnancy to lactation. In some cows this is less successful and they develop severe negative energy balance, placing them at risk of metabolic and infectious disease and reduced fertility. We placed Holstein Friesian cows into metabolically BALANCED or IMBALANCED clusters using as biomarkers measurements of plasma nonesterified fatty acids, β-hydroxybutyrate, glucose and IGF-I collected at 14 and 35 day in milk (DIM). To determine underlying mechanisms associated with their metabolic and immune dysfunction, we performed stranded total RNA sequencing using whole blood cells collected from some of the animals.

LncRNA-sequencing of bovine MAC-T cells

Project description:Escherichia coli and Staphylococcus aureus are two common pathogenic microorganisms that cause mastitis in dairy cows. They can cause clinical mastitis and subclinical mastitis. In recent studies, lncRNAs have been found to play an important role in the immune responses triggered by microbial inducers. However, the actions of lncRNAs in bovine mastitis remain unclear. The purpose of this study was to explore the lncRNA profile on mastitis.

Feeding a Saccharomyces cerevisiae fermentation product improves udder health and immune response to a Streptococcus uberis mastitis challenge in mid-lactating dairy

Project description:Supplementation of a Saccharomyces cerevisiae fermentation product modulates dairy cows health by reducing incidence and severity of mastitis, one of the most common and economically important diseases of the dairy industry. However, mechanisms remain unclear. We conducted a comprehensive molecular analysis, along with physiological data, on dairy cows supplemented for 45 days with NutriTek, a commercially available S. cerevisiae fermentation product, and then subjected to a mastitis challenge . NutriTek supplementation improved cow’s responses to a mastitis challenge by stimulating influx of immune cells to the mammary gland , enhancing their bactericidal capacity, and protecting mammary tissues from the side effect of an immune response allowing faster and more complete recovery from milk production drop

Transcriptome profiling of m6A mRNA modification in inflammation of bovine mammary epithelial cells infected by Staphylococcus aureus and Escherichia coli

Project description:Mastitis is a common disease in dairy cows and brings massive losses to the dairy industry. m6A is a type of modification strongly associated with many diseases. However, the role of m6A in mastitis caused by Staphylococcus aureus and Escherichia coli has not been investigated.We used MeRIP-seq technology to sequence the bovine mammary epithelial cells (MAC-T) infected with inactivated S. aureus/E. coli for 24 h.

Impact of intramammary treatment on gene expression profiles of bovine mammary gland tissue after challenge with E. coli

Project description:The benefit of treatment in mild to moderate cases of E. coli mastitis in dairy cows remains a topic of discussion. We investigated the effect of intramammary treatment with Cefapirin + Prednisolone compared to Cefapirin only on gene expression profiles in experimentally induced E. coli mastitis.

Preliminary cell culture models for subclinical mastitis in sheep

Project description:Ovine mastitis is defined as the inflammation of the sheep udder, most commonly caused in response to intramammary infections. Based on the occurrence of clinical signs, mastitis is characterized as either clinical or subclinical (SCM). The impact of ovine SCM on the overall sustainability of dairy sheep farms has been documented underpinning the significance of efficient diagnosis. Although SCM can be detected in cows, the performance and the validity of the methods used do not transfer in dairy sheep. This fact challenges the development of evidence-based ovine udder health management protocols and renders the detection and control of ovine mastitis rather problematic. Currently, cell culture-based models are being successfully used in biomedical studies and have also been effectively used in the case of bovine mastitis. The objective of the present study was to culture ovine primary mammary cells for the development of 2D and 3D cell culture-based models for the study of ovine SCM. Cells were infected by mastitis-inducing pathogens mimicking the pathogenesis of SCM as derived by natural intramammary infections. The secreted proteins were subjected to mass-spectrometry resulting in the identification of 79 distinct proteins. Among those, several had already been identified in healthy or mastitic milk, while others were detected for the first time in the ovine mammary secretome. The development of cell-based models for the early detection and the overall study of SCM has the potential to be applicable and beneficial for the udder health management in dairy sheep.

Gene expression profiling of human whole-blood samples before and after the administration of recombinant human erythropoietin

Project description:As part of cross-platform comparisons of microarray and RNA-seq, this current experiment using the Affymetrix Human Transcriptome Array 2.0 aimed to quantify gene-level expression in subjects administered recombinant human erythropoietin over a 10-week protocol for the identification of gene signatures of blood doping. These results were compared to results obtained from other gene expression quantification platforms using the same experimental cohort, including the Illumina HumanHT-12v4 Expression BeadChips (archived in ArrayExpression; E-MTAB-2874), Illumina NextSeq 500 and MGI DNBSEQ-G400RS.

Expression of exosomal microRNAs in bovine serum with clinical or subclinical mastitis

Project description:Bovine mastitis causes changes in the serum exosomal miRNAs expression. Serum samples from healthy dairy cows (n = 7) were compared to those of cows with subclinical (n = 7 ) using small RAN sequencing. Three hundred fifty-five miRNAs (341 known and 14 novel ones) were identified. There were 42 miRNAs up-regulated in serum-derived EVs from cows with subclinical mastitis, including bta-miR-1246, bta-miR-2431-3p, bta-miR-126-3p, bta-miR-29a, etc. The MAPK signaling pathway was the most affected pathway by clinical mastitis. Thus, miRNA alterations in mastitis serum-derived EVs support the potential regulator role of specific miRNAs as exosomal cargo in clinical mastitis physiology.

Expression profiling of microRNA from peripheral blood of dairy cows in response to Staphylococcus aureus-infected mastitis

Project description:Purpose: To identify the expression profiling of miRNA in peripheral blood of dairy cows in response to S. aureus-infected mastitis and explore the biomarkers for early diagnosis of S. aureus-infected mastitis. Methods: RNAseq technology was used to determine the expression profiles of microRNA (miRNA) from peripheral blood of Chinese Holstein cows infected with S. aureus at 0, 1, 3, 5, and 7 days. Results: Ttal of 288 differentially expressed miRNAs (DIE-miRNA) including 108 known and 180 novel predicted miRNAs, involved in 10 immune system-related signaling pathways. Compare with the 0 dpi, the number of DIE-miRNAs in 1, 3, 5, and 7 dpi groups were 12, 21, 75, and 48, respectively. It was also found that the expression variation of up-regulated expression of miR-320a, miR-19a, and miR-19b as well as down-regulated expression of miR-143, miR‑205, and miR‑24 reached a significant level on the 5 dpi and 7 dpi. However, at different times after S. aureus infection, miR-1301 was significantly up-regulated in peripheral blood. miR-2284r was significantly down-regulated. Conclusion: miR-1301 and miR-2284r might be the new blood biomarkers for S. aureus-infected dairy cow mastitis. The above results laid a new foundation for the research and development of molecular diagnosis and biological therapy technology for S. aureus-infected mastitis in dairy cow.
