Pathways in cancer, ErbB signalling pathway, insulin signalling pathway, adipocytokine signalling pathway, focal adhesion, renal cell carcinoma, aldosterone‐regulated sodium reabsorption, neurotrophin signalling pathway, Fc gamma R‐mediated phagocytosis and TGF‐beta signalling were co‐regulated by hsa‐miR‐4324, hsa‐miR‐203a, hsa‐miR‐199b‐5p in stage I of NPC (Table 3). This evidence concerns the gene INS and renal cell carcinoma.
