Hemodynamic regulation of tumor necrosis factor-alpha gene and protein expression in adult feline myocardium

During the metastatic cascade, a tumor cell passes through several connective tissue barriers which consist of various adhesive molecules, such as fibronectin, laminin, collagens, and other glucoproteins and proteoglycans. Tumor invasion is a complex process involving cell adhesion, motility (migration), and the degradation of tissue barriers caused by the different proteases secreted by tumor cells. Therefore, understanding the invasion mechanism and the control mechanisms of the invasive properties of tumor cells may help in the development of anti-metastatic and anti-invasive therapies. We here focused our attention on the functional molecules involved in the invasive process as targets to control tumor metastasis, and screened the inhibitors of tumor invasion into basement membranes.
