Furthermore, the influence of AEA on various tumors has already been investigated in terms of the induction of apoptosis in melanoma cells [33], disabled production of several important growth factors by breast cancer cells (such as vascular endothelial growth factor, VEGF; [34]), and the inhibition of the epithelial-mesenchymal transition (EMT) of breast cancer cells [35]. The gene discussed is VEGFA; the disease is breast cancer.
