Application of Next Generation Sequencing (RNA-seq and miRNA-seq) to study the molecular signature of Aluminium hydroxide adjuvant in ovine encephalon. [miRNA-Seq]

Project description:We report the application of miRNA sequencing technology for high-throughput profiling of the aluminium hydroxide adjuvant mechanism of action in an in vivo experiment on sheep. We mapped about 13.1 million sequence reads per sample to the sheep genome (build Oar3.1) and identified 299 miRNAs in the encephalon of sheep treated with commercial vaccines, with the adjuvant alone or with PBS (control group). A total of 2, 38 and 7 differentialy expressed miRNAs were identified in the Vaccine vs. Control, Adjuvant vs. Control and Adjuvant vs. Vaccine comparisons, respectively. Furthermore, miRNA target prediction was performed and it was integrated with previous RNA-seq data in the same animals to predict reliable miRNA-mRNA interactions. Previously reported miRNAs related to brain injury and neurodegenerative diseases were found differentially expressed. Within the negatively correlated targets of the differentially expressed miRNAs there are factors that are clearly related with mitochondria, to maintenance of neuronal polarity and axon growth and to apoptosis. Taken together, our analysis provides characterization of alterations in the miRNAome caused by the aluminium adjuvant alone, while the commercial vaccine not cause great changes, and identifies some targets of the differentially expressed miRNAs which have been previously linked to mitochondrial dysfunction. Aluminum might be causing an imbalance in metal ion levels, among them Mg, in the parietal lobe cortex of animals vaccinated with the adjuvant alone.

Application of Next Generation Sequencing (RNA-seq and miRNA-seq) to study the molecular signature of Aluminium hydroxide adjuvant in ovine peripheral blood mononuclear cells (PBMCs) [miRNA-Seq]

Project description:We report the application of miRNA sequencing technology for high-throughput profiling of the aluminium hydroxide adjuvant mechanism of action in an in vivo experiment on sheep. We mapped about 13 million sequence reads per sample to the sheep genome (build Oar3.1) and identified 95 miRNAs in the PBMCs of sheep treated with commercial vaccines or with the adjuvant alone. A total of 3, 6 and 1 differentialy expressed miRNAs were identified in the vaccine tf VS vaccine t0, adjuvant tf VS adjuvant t0 and adjuvant tf VS vaccine tf comparisons, respectively. Furthermore, miRNA target prediction was performed and it was integrated with previous RNA-seq data in the same animals to predict reliable miRNA-mRNA interactions. Previously reported miRNAs related to alterations caused by aluminium adjuvant were found differentially expressed, namely: miR-19b and miR-125b. Within the negatively correlated targets of the differentially expressed miRNAs there are factors that are clearly related with the response to stimulus, RNA binding and cellular response to DNA damage. Taken together, our analysis provides characterization of alterations in the miRNAome caused by the aluminium adjuvant and identifies some targets of the differentially expressed miRNAs which have been previously linked to the immune system. The overrepresentation of genes related to DNA damage stimulus and DNA repair in both groups may be due to miRNA-mediated regulation.

Application of Next Generation Sequencing (RNA-seq and miRNA-seq) to study the molecular signature of Aluminium hydroxide adjuvant in ovine peripheral blood mononuclear cells (PBMCs) [RNA-Seq]

Project description:We report the application of RNA sequencing technology for high-throughput profiling of the aluminium hydroxide adjuvant mechanism of action in an in vivo experiment on sheep. We mapped about 52 million sequence reads per sample to the sheep genome (build Oar3.1) and identified 21,274 genes in the PBMCs of sheep treated with commercial vaccines or with the adjuvant alone. A total of 2473, 2980 and 429 differentialy expressed genes were identified in the vaccine tf VS vaccine t0, adjuvant tf VS adjuvant t0 and adjuvant tf VS vaccine tf comparisons, respectively. Previously reported genes related to alterations caused by aluminium adjuvant were found differentially expressed, namely: NLRP3, IL1B, IL8, TNF, NFKB2, RELA and RELB. In addition, most of the genes related to apoptosis were up-regulated in both group after treatment. In contrast, other genes related to immune response, inflammatory response and cell-cell signalling were up-regulated in Vac-injected sheep and whereas down-regulated in Adj-injected animals. Taken together, our analysis provides characterization of alterations in the transcriptome caused by the aluminium adjuvant and identifies increased expression of inflammatory cytokines, NF-KB family genes and apoptotic genes.

Application of Next Generation Sequencing (RNA-seq and miRNA-seq) to study the molecular signature of Aluminium hydroxide adjuvant in ovine encephalon. [RNA-Seq]

Project description:We report the application of RNA sequencing technology for high-throughput profiling of the aluminium hydroxide adjuvant mechanism of action in an in vivo experiment on sheep treated with commercial vaccines, with the adjuvant alone or with PBS (control group). We mapped about 74.1 million sequence reads per sample to the sheep genome (build Oar3.1) and after filtering 16,369 genes were expressed, of which 14,387 were annotated genes in Ensembl and 1,982 were candidate lncRNAs. A total of 13, 63 and 76 differentialy expressed genes were identified in the Vaccine vs. Control, Adjuvant vs. Control and Adjuvant vs. Vaccine comparisons, respectively. Previously reported genes related to neuronal development, brain transport and neurotransmission, brain injury and neurodegenerative diseases associated with aluminum were found differentially expressed, namely VCAM1, TRPM4, GDF10 and NTN1.

Identification and characterization of miRNAs in spleens of sheep subjected to repetitive vaccination

Project description:Spleen miRNA profiles of twelve age-matched Rasa sheep after inoculation of nine different commercial vaccines based of aluminium hydroxide (the vaccine group composed of 4 animals), with the aluminium adjuvant alone in an equivalent dose (the adjuvant group composed of 4 animals) or PBS (the control group composed of 5 animals) were generated by deep sequencing on an Illumina HiSeq2500 sequencer.
