Core Tip

Core tip: G protein-coupled estrogen receptor (GPER) is a membrane-bound estrogen receptor that participates in the rapid non-genomic actions of estrogens involving numerous downstream signaling pathways. GPER is expressed in the gastrointestinal tract and is engaged in physiological and pathophysiological processes in the colon. This review aims to assess the significance of GPER expression and estrogenic signaling in colorectal carcinogenesis.
