In the article “Impaired Synaptic Plasticity and Learning in Mice Lacking β-Adducin, an Actin-Regulating Protein,” by Rebecca L. Rabenstein, Nii A. Addy, Barbara J. Caldarone, Yukiko Asaka, Lore M. Gruenbaum, Luanne L. Peters, Diana M. Gilligan, Reiko M. Fitzsimonds, and Marina R. Picciotto, which appeared on pages 2138-2145 of the February 23, 2005 issue, the authors regretfully omitted a reference to work by Marro et al. on another line of β-adducin knock-out mice [Marro ML, Scremin OU, Jordan MC, Huynh L, Porro F, Roos KP, Gajovic S, Baralle FE, Muro AF (2000) Hypertension in β-adducin-deficient mice. Hypertension 36: 449-453]. The authors would like to point out the following: “This article by Marro et al. describes elevated blood pressure in β-adducin null mice; however, as stated in our paper, we did not detect blood pressure differences in the line of β-adducin knock-out mice in our study, likely because of differences in genetic background. The study by Marro et al. used C57BL/6 congenic mice, whereas we analyzed mice on an inbred 129/Sv background.”
