SST and rheumatoid arthritis: In our results, SST activated immune pathways such as the cytokine receptor pathway (mmu04060), the TNF signaling pathway (mmu04668), rheumatoid arthritis pathway (mmu05323), NOD-like receptor signaling pathway (mmu04621) but it also repressed other immune-related pathways such as the systemic lupus erythematosus pathway (mmu05322), the complement and coagulation pathway (mmu04610), and the Staphylococcus aureus infection pathway (mmu05150) (Figure 4).
