Our results demonstrate that pathways with differentially expressed genes included 'metabolic pathways' (19 genes), 'HTLV-I infection' (13 genes), 'microRNAs in cancer' (10 genes), 'MAPK signaling pathway' (7 genes), 'transcriptional misregulation in cancer' (6 genes), 'PI3K-Akt signaling pathway' (9 genes) and 'cell cycle' (5 genes) (Fig. 2c). Here, AKT1 is linked to cancer.
