Before revision:  Specifically, signaling pathways upregulated by SARS-CoV-2 infection and their associated gene ontologies (GOs) were extracted and clustered to generate 10 super-GOs.
After revision:  Specifically, signaling pathways upregulated by SARS-CoV-2 in human lung epithelial cells through analysis of the altered gene expression profiles. In addition to the signaling pathway analysis, the activated gene ontologies (GOs) were extracted and clustered to generate 10 super-GOs.
