Project description:Hypertrophic cardiomyopathy (HCM) is the most common inherited myocardial disease with significant genetic and phenotypic heterogeneity. To search for novel biomarkers, which could increase the accuracy of HCM diagnosis and possibly improve understanding of its phenotype formation, we analyzed the levels of circulating microRNAs (miRNAs) − stable non-coding regulatory RNAs. Performed high throughput sequencing of miRNAs in plasma of HCM patients and controls pinpointed miR-499a-5p as one of 35 miRNAs dysregulated in HCM.
Project description:This study utilized TMT to characterize the cardiac proteomic differences between patients with hypertrophic cardiomyopathy and controls.
Project description:This study used TMT-pro method to look for phosphoproteomic differences in heart tissue of patients with hypertrophic cardiomyopathy and controls
Project description:Using a high-throughput gene expression profiling technology, we have illuminated novel potential microRNA (miRNA) components of the molecular disease process underlying human hypertrophic cardiomyopathy (HCM). It is hoped that this will fuel future research endeavors that will eventually uncover the role miRNAs may play in the phenotypic heterogeneity of the disease, and thus, provide potential tools for identifying patients with benign versus malignant forms of the disease. Case (n = 107)-Control (n=20) study comparing the microRNA transcriptome of cardiac tissues from patients with hypertrophic cardiomyopathy to the microRNA transcriptome of control donor cardiac tissues.
Project description:Using a high-throughput gene expression profiling technology, we have been able to develop new hypotheses regarding the molecular pathogenic mechanisms of human hypertrophic cardiomyopathy (HCM). It is hoped that these hypotheses, among others generated by this data, will fuel future research endeavors that will uncover novel biomarkers, prognostic indicators, and therapeutic targets to improve our ability to diagnose, counsel, and treat patients with this highly heterogeneous and potentially life-threatening condition. Case-control study comparing the messenger RNA transcriptome of cardiac tissues from patients with hypertrophic cardiomyopathy to the transcriptome of control donor cardiac tissues.
Project description:Left ventricular hypertrophy, myocardial disarray and interstitital fibrosis are the hallmarks of hypertrophic cardiomyopathy (HCM). Access to the myocardium for diagnostic purposes is limited. Circulating biomolecules reflecting the myocardial disease processes could improve early detection of HCM. Circulating miRNAs have been found to reflect disease processes in several cardiovascular diseases. Circulating miR-1, miR-495-3p and miR-4454 levels are elevated in plasma of HCM patients. miR-4454 is suggested as a potential biomarker for fibrosis in these patients.
