RegIV, a novel member of regenerating gene family, is located at 1p12-13.1, encoding a 17-kDa secreted protein, which is constitutively expressed in the epithelium of normal pancreas and gastrointestinal tract, whereas the expression is up-regulated in inflammatory or neoplastic tissues. RegIV is involved in the carcinogenesis, progression, metastasis and drug resistance of alimentary system neoplasms, and is thought to be useful to make a forecast of the prognosis. It may serve as a new important target for the prevention, diagnosis and treatment of gastrointestinal neoplasms.
