AB The aim of this study was to assess the molecular effect of ulipristal acetate (UPA) on gene expression in myometrium and endometrium of patients with symptomatic fibroids. Tissues isolated from fourwomen treated preoperatively with UPA (5 mg) were compared to those from untreated controlsusing NanoString platform to assess the expression of 75 candidate genes modulated by UPA andovarian steroids. Deregulated genes were then validated by real-time PCR. In myometrium, UPA exerted an antagonistic effect similar to that observed in fibroids. In UPA-treated endometrium, six genes were identified as highly and significantly upregulated, including matricellular genes CCN1 (54-fold, P = 0.0018) and CCN2 (11-fold, P = 0.00044), Krüppel-like factor 4 (>3-fold, P = 0.0036), and mast cell markers including tryptases TPSAB1/TPSB2 (31-fold, P = 0.023) and carboxypeptidase A (CPA3, 17-fold, P = 0.05). In endometrium, UPA induced the expression of genes involved in fibrogenesis and mast cellfunction—some of them being widely involved in hepatic injury, which could explain the markedfibrosis and inflammatory cell infiltration observed in explanted livers from patients under UPAtreatment.
