RESEARCH INTEREST
The long-term focus of the research program in Dr. Zhou’s laboratory is to unravel the mechanisms regulating the phenotype of vascular smooth muscle cells (VSMCs), an essential cell type in the blood vessels that carry blood throughout the body. The Zhou lab seeks to define the epigenetic and transcriptional mechanisms controlling smooth muscle cell behavior that contributes to cardiovascular development, homeostasis, and disease. Current focus is on two major areas: Hippo-YAP-TEAD signaling and long non-coding RNAs (lncRNAs) in VSMCs.
Dr. Zhou is one of the first to uncover important biological roles of the Hippo-YAP-TEAD pathway in the cardiovascular system. His pioneering work showed that YAP plays a dual role in VSMCs, whereby YAP not only attenuates SM-specific gene expression, but also promotes VSMC proliferation (Wang et al, ATVB, 2012). Functional studies in mice further showed that conditional deletion of YAP in embryonic SMCs led to a hypoplastic vascular wall by diminishing VSMC proliferation (Wang et al, Circulation Research, 2014. Cover article). Recently, Dr. Zhou’s lab have generated an inducible SMC-specific YAP knockout mouse to study the function of YAP in postnatal VSMCs (Islam et al, JMCC, 2021). Dr. Zhou’s lab have expanded their focus in this direction by investigating the nuclear effector of Hippo signaling, TEAD1, in the cardiovascular system (Liu et al, JBC, 2014; Wen et al, Cell Death and Differ., 2019; Osman et al, Circulation Research, 2019; Liu et al, Cell Death and Differ., 2021). Together, these studies show that TEAD1 plays a crucial role, not only in cardiovascular development, but also in cardiomyocyte homeostasis and vascular remodeling. These exciting findings highlight the critical role of the evolutionarily conserved Hippo-YAP-TEAD pathway in cardiovascular biology.
In recent years, Dr. Zhou’s laboratory has developed a robust research program in the emerging research area of long non-coding or circular RNAs (Wang et al, JBC, 2010; Xu et al, ATVB, 2015; Ahmed et al, PNAS, 2018; Dong et al, BMC Medical Genomics, 2020; Dong et al, Circulation, 2021; He et al, Gastroenterology, 2023). Of note, his group identified CARMN, which was initially annotated as the host gene of the MIR143/145 cluster, as a highly abundant and conserved, SMC-specific lncRNA (Dong et al, Circulation, 2021). Recent work from his group further revealed that the lncRNA Carmn is a critical regulator of intestinal smooth muscle contractility (He et al, Gastroenterology, 2023), suggesting a crucial role of lncRNA in smooth muscle. This exciting new direction is likely to yield breakthroughs that will push the boundaries of our knowledge of smooth muscle biology.
Dr. Zhou’s laboratory utilizes integrative approaches that range from in-silico analysis to wet-lab studies using molecular and whole animal approaches. His research has been continuously funded by the NIH and the American Heart Association (AHA). Dr. Zhou has a consistent track record of research productivity and innovation in smooth muscle biology. Dr. Zhou is also a dedicated mentor and highly motivated to train the next generation of cardiovascular scientists.
Dr. Zhou’s laboratory is currently seeking motivated postdoctoral fellows and Ph.D. students to join his dynamic research team. If you are interested in scientific discovery and exploring the inner workings of the cardiovascular system, please contact Dr. Zhou at jizhou@augusta.edu.
