RPL19 and COVID-19: Interestingly, a COVID‐19‐related pathway appeared in both normoxia (RPS25, RPS24, RPL9, RPS27A, RPL28, RPS7, and NRP1) and hypoxia (STAT2, EGFR, NRP1, PRKCA, RPS27A, RPL37A, RPL6, RPL17‐C18orf32, RPS2, RPS5, RPL19, RPL27, and RPL11), further supporting that KDM4B may play crucial roles in the immune response against COVID‐19 infection.
