GO enrichment analyses of DEGs and DEPs of the diaphragm in response to CMV. The 30 top-ranked GO terms enriched by the DEGs of the diaphragm in a young rats and b old rats. c Comparative network analyses of the GO terms of both young and old rats. d The 10 top-ranked GO terms enriched by the DEPs of the diaphragm in old rats. BP: biological process; CC: cellular component; MF: molecular function. Z-score is used as a hint or a prediction of the status of the enriched GO terms. Negative z-score (in green) represents “downregulation” status, whereas positive z-score (in red) represents “upregulation” status of the GO terms
