Functional annotation and enrichment analysis of differentially expressed miRNAs. A, Enriched GO terms of different expression exosomal miRNAs (blue represents the biological process; red represents cellular component; and orange indicates molecular function). The y‐axis shows gene functions, and the x‐axis corresponds to the per cent of miRNAs and number of samples. B, Kyoto encyclopedia of genes and genomes enrichment analysis of differentially expressed miRNAs in chicken type II pneumocyte‐derived exosomes (the most enriched top 30 pathway terms: pink, cellular processes; purple, environmental information processing; blue, genetic information processing; light blue, human diseases; green, metabolism; and yellow, organismal systems). The horizontal axis denoted the −log10 (P‐value) and the number of miRNAs, while the vertical axis indicated the pathway name. The right grey histogram indicates the numbers of samples in each cluster
