Pathways such as ‘Ribosome’, ‘Neuroactive ligand-receptor interaction’, ‘Coronavirus disease-COVID-19’, ‘JAK-STAT signaling pathway’, ‘Alcoholic liver disease’, ‘Serotonergic synapse’, and ‘Signaling pathways regulating pluripotency of stem cells‘ were significantly enriched as upregulated, while ‘Tight junction’, ‘Systemic lupus erythematosus’, ‘Cell adhesion molecules’, ‘Thyroid hormone signaling pathway’, ‘Herpes simplex virus 1 infection’, ‘Pancreatic secretion’, and ‘T cell receptor signaling pathway‘ were significantly enriched as downregulated (Figure 8B). This evidence concerns the gene TG and COVID-19.
