Project description:Truncating variants in titin can cause dilated cardiomyopathy, however, the role of missense titin variants is less clear. In humans the heterozygous titin A178D variant is associated with dilated cardiomyopathy with left ventricular non-compaction. Using CRISPR-Cas9 mediated homology-directed repair the A178D titin variant was introduced into a mouse model. Homozygous A178D mice showed features of dilated cardiomyopathy. Total RNA was extracted from the left ventricles of WT and homozygous A178D littermate control mice and RNA-sequencing performed. Different patterns of gene expression were identified in wildtype and homozygous A178D left ventricles.
Project description:Gene expression in the right ventricle is different in control patients as compared to either idiopathic dilated cardiomyopathy or pulmonary arterial hypertension Two human hearts obtained at autopsy from each of control, pulmonary hypertension, and dilated cardiomyopathy
Project description:We used whole exome sequence to identify de novo mutations in patients with ocular coloboma. Three of these encoded actin pathway components, ACTG1, TWF1 and LCP1. Mass spectrometry-based interactomes of wild-type and mutant proteins were performed to reveal altered functional interactions for all three variants.

Project description:Characterization of plasma metabolomic profile of 15 patients with advanced heart failure referred for heart transplantation (8 patients with chronic chagasic cardiomyopathy and 7 with idiopathic dilated cardiomyopathy) and 12 heart donor individuals using gas chromatography/quadrupole time-of-flight mass spectrometry.
