In the article “Cannabinoid Receptor 1 Influences Chromatin Remodeling in Mouse Spermatids by Affecting Content of Transition Protein 2 mRNA and Histone Displacement” by Teresa Chioccarelli, Giovanna Cacciola, Lucia Altucci, Sheena E. M. Lewis, Luke Simon, Giulia Ricci, Catherine Ledent, Rosaria Meccariello, Silvia Fasano, Riccardo Pierantoni, and Gilda Cobellis (Endocrinology 151:5017–5029, 2010), the authors report that they inadvertently left off one of the supporting grants. The full grant list should be “This work was supported by W.P.4 Sorveglianza sanitaria ex esposti amianto, Organon Schering Plough, Ulster Garden Villages, Northern Ireland, and PRIN Pierantoni 2008”. The authors apologize for this oversight.
In the article “17β-Estradiol Rapidly Increases KATP Activity in GnRH via a Protein Kinase Signaling Pathway” by Chunguang Zhang, Martin J. Kelly, and Oline K. Rønnekleiv (Endocrinology 151:4477–4484, 2010), due to an error in editing, the twelfth line in the abstract is incorrect and should read “E2-BSA was equally as effective as E2, whereas 17α-estradiol had no effect.” The printer apologizes for this error.
