Omicron-infected cats showed enrichment in GO terms (Figure 6C) including activation of innate immune responses, protein localization to the endoplasmic reticulum, response to stress, and regulation of mRNA splicing while KEGG Pathways (Figure 6D) revealed involvement of T-cell receptor signaling, several cellular signaling pathways including MAPK, PI3K-Akt, mTOR, and COVID-19 pathways compared to controls. This evidence concerns the gene MTOR and COVID-19.
