Data processing

Fastq format raw reads (raw data) were handled through in-house perl scripts. Clean reads (clean data) were gained by removing adapters, ploy-N and low quality reads from raw reads (raw data). Meanwhile, Q20, Q30 and GC content of the clean data were evaluated. The paired-end clean reads were mapped to the pig genome sequence assembly (Sscrofa 10.2) with Tophat (v2.0.9) software.
CNCI, CPC, PFAM and phyloCSF, were used to obtain the candidate lncRNA. Firstly, transcripts without coding potential were achieved using any of the four tools with earlier described instructions. Next, those without coding potential shared by four tools were screened as the candidate lncRNAs for subsequent research.
The genes expression level of both lncRNAs and protein-coding in each sample was calculated by FPKM (fragments per kb for a million reads) evaluated using Cuffdiff (v2.1.1)
To explore transcripts conservation, the Phast (v1.3) software was widely used for phylogenetic analysis and thus phastCons expression.
Gene Ontology (GO) enrichment analysis of differentially expressed genes or lncRNA target genes were implemented by the GOseq R package. KOBAS software was performed to test the statistical enrichment of differential expression genes or lncRNA target genes in KEGG pathways.
Coding genes 10k/100k upstream and downstream of lncRNA were treated as the cis target gene. Then, the trans role of lncRNA is to identify using the expression level.
