The cHubGs regulatory network analysis commonly detected SARS-CoV-2 and IPF diseases causing two crucial transcriptional (JUN and NFKB1) and post-transcriptional (hsa-mir-155-5p and hsa-mir-21-3p) regulators of cHubGs based on three independent databases JASPAR, TarBase and RegNetwork. The gene discussed is JUN; the disease is idiopathic pulmonary fibrosis.
