IL17A and cancer: The top 10 upregulated enriched pathways from TCGA GC dataset included cytokine-cytokine receptor interaction, neuroactive ligand-receptor interaction, transcriptional dysregulation in cancer, complement, and coagulation cascades, viral protein interaction with cytokine and cytokine receptor, the IL-17 signaling pathway, the Wnt signaling pathway, signaling pathways regulating pluripotency of stem cells, ECM-receptor interaction and protein digestion and absorption (Figure 2D, Supplementary Table 5).
