(A) The volcano plots of differentially expressed genes (DEG) enriched in chicken uterovaginal junction (UVJ) folds containing sperm storage tubules (SST) (day 9 vs. day 3 after artificial insemination [AI]). The X-axis and Y-axis represented the log2 fold change values and the statistical significance P values (−log10), respectively. The red and green dots represented upregulated and downregulated mRNA expression of DEG, with expression exceeding the threshold value within log2 fold change values between 0.5 and −0.5, P value < 0.05. The blue dots represented the genes with expression level beyond the stated threshold of P value < 0.05. (B) Protein-protein interaction network of DEG in mated chicken UVJ folds (day 9 vs. day 3 after AI). Network nodes and edges represented proteins and protein-protein associations, respectively. The red and green nodes represented downregulated and upregulated genes, respectively. (C) The top 30 enriched biological processes of DEG comparing the UVJ containing SST at day 9 to day 3 after AI. (D) The top 20 enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways of DEG in UVJ comparing between day 9 and day 3 after AI.
