Cancer cells often express a massive amount of proteins that are needed to their own proliferation. One of the molecular abnormalities related to tumour progression, invasion and fixation requires the impairment of E-cadh expression, a tumour invasion suppressor protein. Epithelial‑mesenchymal transitions (EMT), is associated with the silencing of E-cad expression and further expression of EMT related molecules, such as Akt2 and Twist, crucial for progression of non-invasive into a malignant metastatic carcinomas, due to a polarity and adhesion loss between adjacent cells.
