Osteopontin (OPN), also known as bone sialoprotein 1, nephropontin secreted phosphoprotein 1 and uropontin, is an acidic glycoprotein and is a member of the intrinsically disordered class of proteins (Kurzbach et al.
2013).
OPN plays a role in a multitude of physiological and pathophysiological processes.
In inflammation it induces cell adhesion and migration, regulates differentiation of proinflammatory lymphocytes and inhibits apoptosis of inflammatory cells (Clemente et al.
2016).
OPN is expressed by various cell types including bone, neural, epithelial and endothelial cells.
It is also expressed by the immune cells T cells, B cells, natural killer cells and macrophages.
In its secreted form OPN can be found in biological fluids such as blood, urine, bile and milk (Castello et al.
2017).
OPN has been found to play a role in cancer progression by enhancing proliferation, survival, motility and invasion of tumor cells in a range of cancers.
OPN was upregulated at tumor sites and in blood of the patients, with the level correlating with tumor stage and aggressiveness (Castello et al.
2017).
High levels of OPN have also been detected in several autoimmune diseases including multiple sclerosis and rheumatoid arthritis (Clemente et al.
2016).
