Diacylglycerol kinase α mediatses 17-β-estradiol-induced proliferation, motility, and anchorage-independent growth of Hec-1A endometrial cancer cell line through the G protein-coupled estrogen receptor GPR30
Increased levels of endogenous and/or exogenous estrogens are one of the well known risk factors of endometrial cancer. Diacylglycerol kinases (DGKs) are a family of enzymes which phosphorylate diacylglycerol (DAG) to produce phosphatidic acid (PA), thus turning off and on DAG-mediated and PA-mediated signaling pathways, respectively. DGK α activity is stimulated by growth factors and oncogenes and is required for chemotactic, proliferative, and angiogenic signaling in vitro. Herein, using either specific siRNAs or the pharmacological inhibitor R59949, we demonstrate that DGK α activity is required for 17-β-estradiol (E2)-induced proliferation, motility, and anchorage-independent growth of …
Feasibility and Acceptability of Office-Based Polypectomy With a 16F Mini-Resectoscope: A Multicenter Clinical Study
Abstract Study Objective To investigate the feasibility and acceptability of office hysteroscopic polypectomy using a novel continuous-flow operative 16F mini-resectoscope. Design Multicenter prospective case series (Canadian Task Force classification III). Setting “SS Antonio e Biagio” Hospital, Alessandria, and University “Federico II” of Naples. Patients One hundred eighty-two patients with endometrial polyps. Interventions Hysteroscopic polypectomy performed with 16F mini-resectoscope in an office setting, without analgesia and/or anesthesia. Measurements and Main Results Polypectomy was successfully performed in 175 patients in a single surgical step (96.15%), with only 1 patient (.54%…
