Abstract:

Alpha-2-macroglobulin(α2-MG) is the largest protein in plasma,which is synthesized by liver cells and mononuclear macrophage system. Human α2-MG is a homotetramer comprised of 4 same subunits. As a broad spectrum protease inhibitor in plasma,α2-MG is involved in the pathophysiology of many diseases. In this review,the structure and function of α2-MG and its glycosylation are briefly expounded. The research progress on the relationship of α2-MG with liver cancer and other common malignant tumors are reviewed,as well as the research progress on the relationship between α2-MG glycosylation and carcinogensis.

Key words: Alpha-2-macroglobulin, Serum marker, Glycoprotein, Protease inhibitor, Glycosylation, Tumor
