  • Description

    Osteopontin (OPN) has an important role in mineralization, blood vessel formation, cell survival, inflammation and inhibition of iNOS expression which protects tumor cells from NO-mediated macrophage cytotoxic attack. It also is a key molecule in neoplastic transformation and cancer development in a variety of tumors, playing a critical role in invasiveness, progression and metastasis. Plasma OPN has been shown to be a positive indicator of colon and lung cancers, as well as metastatic carcinomas. In addition, OPN mRNA expression increases approximately 40-fold in infarct tissue after a myocardial infarction.
