Before revision:  Using the unique profiles of altered gene expression found in NHBE, A549_ACE2 and Calu3 human lung epithelial cells after Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, we conducted a computational analysis to identify dysfunctional signaling pathways within infected cells.
After revision:  Using the unique profiles of altered gene expression found in NHBE, A549_ACE2 and Calu3 human lung epithelial cells after Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) , molecular signaling of host cells plays critical roles during the life cycle of SARS-CoV-2. Thus, it is significant to identify the involved molecular signaling pathways within infected cells.
