Epigenomic profiling of the innate immune response in bovine MDBK cells

Project description:Cattle are an important livestock species, and understanding the genomic architecture of agriculturally relevant traits such as disease susceptibility is of major interest in the bovine research community. Lineage-specific transposable elements (TEs) are a source of interferon-gamma (IFNG)-inducible regulatory elements that control human immune genes, but this possibility has been largely unexplored in other species that harbor distinct transposon landscapes, including cattle. We conducted transcriptomic and epigenomic profiling of the IFNG response in bovine cells, and found that ruminant-specific TEs are a major source of IFNG-inducible enhancer elements that shape bovine innate immune responses. CRISPR knockout experiments established that key immune genes including bovine IFNAR2 and IL2RB are regulated by TEs in MDBKs. Together with previous work in human cells, our findings demonstrate that lineage-specific TEs have been independently co-opted to regulate IFNG-inducible gene expression in at least two mammalian lineages. Therefore, TE co-option may mediate parallel evolutionary rewiring of mammalian immune regulation.

Differentially-expressed miRNAs in MDBK cells infected with bovine viral diarrhea virus compared to MDBK cells

Project description:Non-canonical microRNAs (miRNAs) are a class of short endogenous RNA molecules with the ability to control development, autophagy, apoptosis and the stress response in eukaryotes by pairing with partially complementary sites in the 3' untranslated regions (UTRs) of targeted genes. Recent studies have demonstrated that miRNAs serve as critical effectors in intricate networks of host-pathogen interactions. Thereforce, the differential expression of miRNAs were evaluated in Madin-Darby bovine kidney (MDBK) cells infected with bovine viral diarrhea virus (BVDV) NADL (100 TCID50/ 0.1 ml) for 6 h compared to normal MDBK cells using Solexa high-throughput sequencing technology (BGI, China).

Role of epigenetic modifiers on the bovine fibroblast innate immune response

Project description:The innate immune signaling pathway plays a crucial role in the recognition and early response to pathogens associated with disease. Genetic analysis has been unable to completely account for individual variability in the strength of the innate immune response. The aim of this study was to determine the role of the epigenetic markers (DNA methylation or histone acetylation) in controlling bovine gene expression in relation to the response to lipopolysaccharide (LPS). To determine the impact epigenetics may have in controlling innate immunity, dermal fibroblasts from fifteen dairy heifers having previously displayed a differential response to LPS were exposed to 5-aza-2M-bM-^@M-^Y-deoxyctidine (AZA) and trichostatin A (TSA); de-methylating and hyper-acetylating agents, respectively. The AZA-TSA Fibroblast cultures (n=3) were examined under either control conditions or for gene expression following epigenetic modification with the de-methylating agent 5-aza-2'-deoxycytidine and hyper-acetylation agent trichostatin-A. Finally, expression was investigated for responsiveness to lipopolysaccharide (LPS)

Transcriptomic characterization of cattle primary hepatocytes and its comparison with Madin-Darby bovine kidney (MDBK) cells and liver tissue

Project description:Cattle primary cultured hepatocytes (CHs) have been used as a useful in vitro model for drug metabolism studies. However, they suffer some limitations, when compared with the ex vivo liver tissue, such as difficult adhesion to the substrate following isolation, a limited viability and a rapid loss of differentiated characteristics. Therefore, a reliable hepatic in vitro model is actually needed for cattle. As established bovine hepatic cell lines are not available, we characterized the cattle primary CHs' transcriptome by using a cDNA microarray approach and compared it with ex vivo cattle liver tissue as well as with the Madin-Darby Bovine Kidney (MDBK) cells (as an established cell line for transfection purposes).<br>This part of the study compares the primary CHs vs. liver tissue. The comparison of MDBK cells vs. the primary CHs is found under E-MTAB-4430.
