| Title |
116-B (miRNA-Seq) |
| Sample type |
SRA |
| |
|
| Source name |
Blood
|
| Organism |
Ovis aries |
| Characteristics |
cell type: PBMC
group: Adjuvant
time: tf
sample source: 6
|
| Treatment protocol |
The animals were treated with two different treatments: one group was inoculated with nine different commercial vaccines and the other one was inoculated only with the adjuvant (aluminium hydroxide, AL(OH)3), giving an equivalent dose of aluminium. Established legal periods between vaccinations were always fulfilled. The vaccination schedule was between February of 2015 and April of 2106, giving a total of 19 doses and 81.5 mg Al3+ per animal during that period.
|
| Growth protocol |
The animals were kept under uniform housing conditions and nutritional regimens in Zaragoza (Spain). All experimental procedures were approved and licensed by the EthicalCommittee of the University of Zaragoza (ref: PI15/14). Requirements of the Spanish Policy for Animal Protection (RED53/2013) and the European Union Directive 2010/63 on protection of experimental animals were always fulfilled.

| Extracted molecule |
total RNA |
| Extraction protocol |
For isolation of ovine peripheral blood mononuclear cells (PBMCs), blood was collected from the jugular vein of 6 Rasa sheep. The blood was collected into heparinised Vacutainer tubes (Becton, Dickinson and Company, Sparks, MD), transferred into 50-ml centrifuge tubes and diluted 1∶2 in HBSS. Twenty-five millilitres of blood:HBSS were layered over 10 ml of Ficoll-Paque (1.084 g/cm3) (GE HealthCare Bio-Sciences, Uppsala, Sweden) in 50-ml centrifuge tubes. Cells were centrifuged at 900×g for 30 min to separate erythrocytes and polymorphonuclear cells from PBMCs. PBMCs were collected from the HBSS-Ficoll-Paque interface, washed with HBSS by centrifugation at 400×g for 10 min, lysed in 1 ml of Trizol and storage at -80 ⁰C until used. Total RNA was extracted from PBMCs using RNA Clean & Concentrator™-5 kit (Zymo Research, Irvine, CA, USA) following manufacturer’s instructions and stored at -80 ⁰C. The TruSeq Small RNA library prep kit (Illumina, San Diego, CA, USA) was used for the construction of sequencing libraries.
miRNA libraries were prepared for sequencing using standard Illumina protocols

| Data processing |
Sequence reads were trimmed and filtered with Trimmomatic [v0.36] to remove adaptor sequences , low quality reads and reads shorter than 16 nucleotides.
The sRNAbench module from the sRNAtoolbox program was applied to map sequences to the reference genome, to profile the expression of known small RNAs from miRBase sheep miRNAs and to predict novel miRNAs. Rfam data was used to identify other small RNAs originating from rRNA, tRNA, snRNA and snoRNA and exclude them from the analysis.
The predicted new miRNAs were searched in the RNACentral database with blastn [v2.7.1] to known if they have been previously identified and to try to annotate them.
Genome_build: Oar_v3.1
Supplementary_files_format_and_content: Tab-delimited text file matrix with the raw counts of sequencing reads for miRNAs. The miRNAs are identified with the miRBase ID and the samples are identified by the name of the title column of the SAMPLES section.
