IL17A and cancer: Other up-regulated pathways included IL-17 signalling (P = 4.9 × 10−05), cytokine–cytokine receptor interactions (P = 1.0 × 10−04), protein digestion and absorption (P = 2.7 × 10−04), pathways in cancer (P = 3.9 × 10−03), extracellular matrix–receptor interactions (P = 0.016), cell adhesion molecules (P = 0.036), and cell cycle (P = 0.036) (Fig 1B and Table S3).
