Antitumor mechanism of Se-containing polysaccharide,a novel organic selenium compound

Recent studies on the inhibition of tumor growth by Se-containing polysaccharide were reviewed.Meanwhile,the possible molecular mechanisms of the inhibition of tumor cell growth through antioxidation,induction of tumor cell apoptosis,blockade of cell cycle,and enhancement of immunity by Se-containing polysaccharide were proposed.In the end,the potential application of Se-containing polysaccharide in the prevention and treatment of tumor was elucidated.
