Olfactory Receptor 51E1 is a Novel Potential Tissue Biomarker for the Diagnosis and Prognosis of Small Intestine Neuroendocrine Tumors Abstract #435

Introduction: Small intestine neuroendocrine tumors (SI-NETs) get late diagnosis. We discovered the olfactory receptor 51E1 (OR51E1) as a potential target to develop as a novel biomarker.
Aim(s): To develop OR51E1 as a SI-NET novel tissue biomarker for diagnostics and prognostics.
Materials and methods: OR51E1 coding sequence was cloned from SI-NET patient specimens and NET cell lines. OR51E1 expression was analyzed by quantitative-real-time-PCR (QRT-PCR) on human normal and NET cell lines; normal liver tissue and normal hepatic cells; microdissected SI-NET cells and stroma cells. OR51E1 protein expression was analyzed by immunohistochemistry (IHC) on SI-NET slides and tissue microarray analysis (TMA). Furthermore, a new polyclonal antibody was developed.
