The Moskowitz laboratory is devoted to the genetic, genomic and molecular study of gene regulatory networks. A single overarching theme governs work in the Moskowitz laboratory: that understanding essential gene regulatory networks will unveil the molecular logic governing biological processes, and that understanding network disruption will inform the molecular basis underlying disease. We have recently pioneered approaches to identify non-coding RNAs as markers and modulators of enhancer function (Yang and Nadadur et al, 2017). The Moskowitz laboratory has focused on two areas of cardiac biology: (1) cardiac conduction with respect to cardiac arrhythmias and (2) cardiac development with respect to Congenital Heart Disease (CHD). In cardiac development, we investigate the genetic, genomic and developmental landscape of cardiac morphogenesis. We have identified an essential role for Hedgehog signaling in the cardiac development and congenital heart disease and contributed to a paradigm shift in the understanding of cardiac septation (e.g. Hoffmann et al., 2009; Xie et al., 2012; Zhou et al., 2017). We have recently identified a surprising and novel role for Hedgehog signaling in maintaining cardiac progenitor status and preventing premature differentiation (Rowton et al., 2018). In cardiac rhythm, we investigate the molecular mechanisms underlying the genetic basis of cardiac arrhythmias. We have defined the first molecular networks and linking GWAS loci in cardiac conduction (Arnolds et al, 2012), the first molecular network in Atrial Fibrillation, the most common arrhythmia world-wide (Nadadur et al., 2016) and the functional genomic mechanisms underlying genetic associations (Van den Boogaard et al., 2014).
