Project description:We created a fetal lamb model of hypoplastic left heart syndrome (HLHS), by implanting coils in the left atrium in mid-gestation. We performed bulk RNA sequencing of left ventricles (LV), right ventricles (RV), ascending aortae (AAo) and pulmonary arteries (PA). Single nucleus RNA sequencing was performed on LV free wall tissue (n = 4 coiled samples, n = 3 controls).

Project description:Complex molecular programs in specific cell lineages govern human heart development. Hypoplastic left heart syndrome (HLHS) is the most severe congenital heart defect encompassing a spectrum of left-ventricular hypoplasia occurring in association with outflow-tract obstruction. The current clinical paradigm assumes HLHS is largely of hemodynamic origin. Here, by combining whole-exome sequencing of 87 HLHS parent-offspring trios and transcriptome of cardiomycytes (CMs) from healthy and patient native ventricles at different stages of development we identified perturbations in coherent gene programs controlling ventricular muscle lineage development. Single-cell and 3D molecular/functional modeling with iPSCs demonstrated intrinsic defects in the cell-cycle/ciliogenesis/autophagy hub resulting in disrupted differentiation of early cardiac progenitor (CP) lineages and ultimate defective CM-subtype differentiation/maturation in HLHS. Moreover, premature cellcycle exit of ventricular CM prevents tissue response to cues of developmental growth leading to multinucleation/polyploidy, accumulation of DNA damage, exacerbated apoptosis, and eventually ventricle hypoplasia. Our results highlight how genetic heterogeneity in HLHS converges in perturbations of sequential cellular processes driving cardiogenesis and facilitate potential novel nodes for therapy beside surgical intervention.

Project description:Affymetrix GeneChip Exon-1.0ST was used to study the differential gene profiles in RV (right ventricle) samples from neonates with HLHS (hypoplastic left heart syndrome) versus RV and LV (left ventricle) samples obtained from age-matched controls. Although few significant changes were observed in the genetic profiles between control LV and control RV, many genes passed the false discovery rate in comparing HLHS-RV to RV and LV control groups, with greater differential profiles noted between HLHS-RV and control RV.

Project description:Congenital heart disease (CHD) is a prevalent birth defect affecting up to 1% of live births. While a genetic etiology is indicated by increased recurrence risk and association with chromosomal abnormalities, the genetics of CHD is poorly understood and likely complex. Here we show hypoplastic left heart syndrome (HLHS), a severe CHD with high morbidity/mortality, has a multigenic etiology. Analysis of 8 HLHS mutant mouse lines recovered from a large-scale mutagenesis screen showed no mutations are shared in common. In the *Ohia* mouse line, mutations in 2 genes, *Pcdha9*/*Sap130*, act synergistically to cause HLHS. Cardiomyocyte proliferation and differentiation defects likely act in concert with valve abnormalities to cause HLHS. Network analysis of mutations recovered in HLHS mice and 68 HLHS patients point to Notch signaling disruption, a pathway previously implicated in HLHS. These findings demonstrate large-scale mutagenesis is an effective systems approach for interrogating the complex genetics of human diseases.
