TFAR19 is a novel apoptosis-related gene and can accelerate cell apoptosis in the presence of apoptosis inducements. Here, we studied the effects of TFAR19 on some biophysical properties of mouse erythroleukemia (MEL) cells and their molecular and structural basis. After transfected with TFAR19 and apoptosis inducement, MEL revealed a high cell membrane fluidity, a decrease in resynthesis of phospholipids, an increase in the proteins/nucleic acids ratio, a relatively orderly cytoskeleton network, an impaired deformability a low integrin aM expression, and a decrease in adhesion to endothelial cells. These findings suggest the potential of TFAR19 for antitumor cell migration, and thus for antitumor gene therapy.
