Project description:We investigated miRNA expression in Holstein dairy cow of mammary gland with different producing quality milk using high-throughput sequence and qRT-PCR techniques. miRNA libraries were constructed from mammary gland tissues taken from a high producing quality milk and a low producing quality milk Holstein dairy cow, the small RNA digitalization analysis based on HiSeq high-throughput sequencing takes the SBS-sequencing by synthesis.The libraries included 4732 miRNAs. A total of 124 miRNAs in the high producing quality milk mammary gland showed significant differences in expression compared to low producing quality milk mammary gland (P<0.05). Conclusion: Our study provides a broad view of the bovine mammary gland small RNA expression profile characteristics. Differences in types and expression levels of miRNAs were observed between high producing quality milk and a low producing quality milk Holstein dairy cow
Project description:Twelve midlactation cows received 4 diets differing in forage-to-concentrate ration (High (HF) versus Low (LF) forage supplemented or not with lipids (HF with whole intact rapeseeds (HF-RS) and LF with sunflower oil (LF-SO)) 12 cows got into 4 groups, each cow was received 4 different diets in a latin square design Green*txt and Red_*txt raw data files contain Cy3 and Cy5 signal intensities, respectively.
Project description:Transcriptional profiling of bovine CD14+ cells comparing endometrial CD14+ cell with blood CD14+ cells from the same pregnant cow . Enzymatically dispersed stromal endometrial cells and peripheral blood mononuclear cells from the same cow were labelled using CD14 antibody as a maker. The labeling with CD14 makes possible the soring of those CD14 cells by FACS. Goal was to determine the effects of pregnancy and the location of CD14+ on global CD14+ cells gene expression.
