The oncogenic pathways affected by SFN are Akt (ovarian cancer) and Wnt/beta catenin (breast cancer) [18-20], whereas, beta catenin accumulation in gastro-intestinal carcinoid cells and the role of PI3K/Akt signaling in pulmonary carcinoids have been established [20,21]. This evidence concerns the gene AKT1 and breast carcinoma.
