The target gene prediction of lncRNAs was divided into cis-target gene prediction and trans-target gene prediction. We screened for genes with protein-coding capabilities within 100 kb upstream and downstream of lncRNAs for cis-regulated target genes corresponding to lncRNAs. The target genes with trans-regulation were screened by calculating the expression correlation (Pearson’s correlation test) or co-expression analysis method between lncRNAs and mRNAs. We used the correlation coefficient > 0.95 and p-value < 0.05 to screen the trans-acting relationship between lncRNAs and mRNAs. Next, the lncRNA-mRNA co-expression network was constructed using Cytoscape.
