The top five results, based on FDR and identified via the KEGG pathway were cytokine-cytokine receptor interactions, pathways in cancer, phosphatidylinositol 3-kinase PI3-AKT signalling, epidermal growth factor receptor (EGFR), tyrosine kinase inhibitor resistance and hypoxia inducible factor (HIF) signalling pathway. Here, EGFR is linked to cancer.
