|
| Organism |
Sus scrofa |
| Characteristics |
diet: cDDGS+rapeseed oil

| Extracted molecule |
total RNA |
| Extraction protocol |
The quantity and quality of the obtained RNA were checked on a NanoDrop 2000 spectrophotometer (Thermo Scientific; Wilmington, USA) and on a TapeStation 2200 instrument (RNAScreen Tape, Agilent, Perlan Technologies, Poland).
microRNA libraries were prepared with the use of NEBNext Multiplex Small RNA Library Prep Set for Illumina (New England Biolabs; E7300L), according the standard protocol. Briefly, the first step was the 3’ adaptor ligation, followed by hybridization with the Reverse Transcription Primer and ligation with the 5’ adaptor. The RNA-adaptor ligation products were subjected to reverse transcription. Then, PCR amplification with 12 different indexed primers was performed to allow further multiplexing of the samples. The amplified samples were purified and size-selected on a Novex 6% TBE PAGE gel (Invitrogen). After the overnight elution from the gel, the libraries were precipitated and purified with ethanol (POCH). Next, they were subjected to a concentration measurement with a Qubit 2.0 Fluorometer (Thermo Fisher Scientific) and a size assessment with a 2200 TapeStation instrument (Agilent). The libraries were stored at -20°C at 10nM concentration until further use.

| Description |
microRNA
|
| Data processing |
demultiplexing: bcl2fastq
quality control: FastQC
trimming off the 3' adapter sequences: UEA sRNA WorkbenchV4.6
filtering: UEA sRNA WorkbenchV4.6; parameters: 17-25 nt in length, minimum abundance of at least 6 supporting reads, tRNA and rRNA sequences excluded.
mapping: the filtered reads were mapped to Sscrofa10.2 genome and miRBase 22.1, using miRCat tool embeded in UEA sRNA WorkbenchV4.6. The following parameters were applied - default animal parameters, except for: minimum abundance (6), minimum length (17 nt) and maximum length (25 nt).
differential expression analysis: DESeq2 (a Bioconductor R-project package)
Genome_build: Sscrofa10.2
Supplementary_files_format_and_content: FASTA files after filtering and adaptor trimming, generated with the use of UEA sRNA Workbench V4.6. They include the number of reads of detected sequences.
