LncRNA-gene network and GO analysis of differentially expressed lncRNAs. (A) Network of 12 lncRNA-gene pairs associated with mouse pronuclear migration. The target genes are displayed as yellow circles, and the differentially expressed lncRNAs are displayed as blue rectangles. (B) Dual-luciferase reporter assay for lnc007956 and Tubb4b. **P<0.01 vs. NC. (C) GO term analysis for the target genes of the differentially expressed lncRNAs. Bar plots showing GO enrichment in various modules. The length of the bars indicates significance (left side, -log10 transformed Benjamini-Hochberg adjusted Q-value) and the target gene count (right side). Actn4, actinin-α4; GO, Gene Ontology; lnc/lncRNA, long non-coding RNA; MUT, mutant; NC, normal control; Tubb4b, tubulin β-4B class IVb; WT, wild-type.
