Pulmonary Carcinoids and Low-Grade Gastrointestinal Neuroendocrine Tumors Show Common MicroRNA Expression Profiles, Different from Adenocarcinomas and Small Cell Carcinomas

Abstract

Carcinoids/NETs had a characteristic pattern of miRNA expression, suggesting a common origin for pulmonary carcinoids and GI-NETs. The expression profiles of pulmonary carcinoids and SCLCs were quite different, indicating the distinct histogenesis of these neuroendocrine neoplasms.
