Expression pattern of GPR30 in endometriosis

Introduction: G-protein coupled receptor 30 (GPR30) is a seven-transmembrane receptor suggested to be part of non-genomic estrogen responses that can, in contrast to the classic or genomic mode of ER action, occur rapidly within minutes. GPR30 mediated estrogen action is involved in multiple physiological processes, as well as pathological processes, as for example the proliferative effects of estrogen and tamoxifen in endometrial cancer cells. Since Estrogen action plays a key role in endometriosis and is partly mediated by GPR30 in a various number of physiological and pathological processes, the investigation of its expression in endometriosis could be of particular interest.
