Prognostic Role of Aryl Hydrocarbon Receptor Interacting Protein (AIP) Immunohistochemical Expression in Patients with Resected Gastric Carcinomas.

Aryl hydrocarbon receptor (AHR) interacting protein (AIP) is a chaperone which binds to inactive AHR in the cell cytoplasm. AHR is best known for mediating the toxicity of halogenated aromatics, but it has also been linked to carcinogenesis and tumor progression in several tumor types. Our aims are to assess the features of AIP immunohistochemical (IHC) staining and to evaluate its possible role as a prognostic marker in gastric cancer (GC).
