Role of Protein Phosphorylation in Neoplastic Transformation

The process of neoplastic transformation can be conceptually divided into two components. The first of these, proliferative transformation, refers to the ability of transformed cells to bypass growth suppression signals, dividing when normal cells would not. The second, morphologic transformation, refers to loss of normal cytoskeletal architecture, often accompanied by decreased adhesion and acquisition of the ability to invade surrounding tissues. These two fundamental properties are intimately linked to one another, although experimentally they can be dissected apart through the use of mutant oncogenes and other abnormal signaling molecules. The overall focus this research is in uncovering the roles of protein phosphorylation in governing these two fundamental aspects of cancer biology.
