According to KEGG enrichment analyses, differentially expressed genes were mainly involved in the MAPK signalling pathway, PI3K-Akt signalling pathway, acute myeloid leukaemia, p53 signalling pathway, chronic myeloid leukaemia, and other signalling pathways (Figure 3(b)). This evidence concerns the gene TP53 and chronic myelogenous leukemia, BCR-ABL1 positive.
