Cardiovascular research, Volume 113, Issue 10, 1 1 2017, Pages 1186-1197 RHOA-ROCK signalling is necessary for lateralization and differentiation of the developing sinoatrial node. Vicente-Steijn R, Kelder TP, Tertoolen LG, Wisse LJ, Pijnappels DA, Poelmann RE, Schalij MJ, deRuiter MC, Gittenberger-de Groot AC, Jongbloed MRM
Aims: RHOA-ROCK signalling regulates cell migration, proliferation, differentiation, and transcription. RHOA is expressed in the developing cardiac conduction system in chicken and mice. In early development, the entire sinus venosus myocardium, including both the transient left-sided and the definitive sinoatrial node (SAN), has pacemaker potential. Later, pacemaker potential is restricted to the right-sided SAN. Disruption of RHOA expression in adult mice causes arrhythmias including bradycard... Abstract
