KEGG pathway analysis revealed 101 upregulated DE genes associated with the coronavirus disease - COVID-19 KEGG pathway, including MAS1 (MAS1 Proto-Oncogene, G Protein-Coupled Receptor, log2fc = 10.46), TNF (Tumor necrosis factor, log2fc = 4.82), MAPK family members such as MAPK11 (Mitogen-Activated Protein Kinase 11, log2fc = 7.10) and MAPK12 (Mitogen-Activated Protein Kinase 12, log2fc = 4.69). Here, TNF is linked to COVID-19.
