Moreover, pathways associated with cancer in general (e.g., “Transcriptional misregulation in cancer”, “Small cell lung cancer” and “Proteoglycans in cancer”) and pathways mainly involved in BC, such as the “PI3K-Akt signalling pathway” and “Hippo signalling pathway”, were deregulated (Fig. 4C). This evidence concerns the gene AKT1 and small cell lung carcinoma.
