Effect of Lysine Acridone Acetate on the Level of Apoptosis and Expression of Apoptosis-Associated Proteins during Antioncogenic Therapy in Colorectal Cancer in Mice

Abstract

We studied the mechanism of action of cytostatics with the addition of lysine acridone acetate to evaluate the possibility of its use for improving the effectiveness of antioncogenic therapy in colorectal cancer. In Nude mouse model, the level of apoptosis (TUNEL) and expression of proteins CD95, p53, Bcl-2, histone H3, and Ki-67 (immunohistochemistry) were assessed in primary tumor biopsy specimens. It has been shown that cytostatic treatment led to stimulation of p53-mediated apoptosis and suppression of proliferation (Ki-67 expression) of tumor cells, and apoptosis level was increased in groups receiving lysine acridone acetate. H3 expression in the experimental groups was changed.

Keywords: apoptosis markers; colorectal cancer; lysine acridone acetate; proliferation.
