Research description

Cardiac outflow tract defects are the most important cause of human congenital heart disease (CHD), the most common malformation in children affecting 1/100 live births. Mal-alignment of the underlying cono-ventricular region with the overlying great vessels results in several serious forms of CHD. While many genes that cause CHD have been identified, the precise mechanisms that link these gene variants with specific cardiac malformations are largely unknown. The central hypothesis of my research projects is that a novel subset of human cono-ventricular progenitors, e.g., human cardiac outflow tract-specific LGR5/ISL1+ progenitors that our group has recently discovered through single-cell omics studies and their downstream progeny would play a critical role in guiding human outflow tract formation through their alignment, migration, expansion, and paracrine guidance cues, and that defects within this specific subset and its functional molecular pathway may play a major causative role in the pathogenesis of human CHD. Thus, my research aim is to first identify more causative CHD genes through cross-referencing single outflow tract progenitors’ RNA/DNA sequencing data obtained from various species during mammalian cardiogenesis with other huge databases showing the existing landscape of human CHD mutations (e.g., Yale's PCGC). The long-term goal is to establish specific pathways that link gene disorders with specific defects in the outflow tract progenitor pool and thereby each morphologic phenotype of CHD, leading to the design of new strategies to mitigate the serious forms of the disease.
