Project description:To explore the primary cause of Dilated Cardiomyopathy in heart samples from DCM-diagnosed patients who had undergone heart transplant (hDCM), we set out to identify differentially expressed genes by massively parallel sequencing of heart samples. Methods: Heart mRNA profiles from DCM-diagnosed patients who had undergone heart transplant (hDCM) were generated by deep sequencing, in triplicate, using Illumina GAIIx.

Project description:To explore the primary cause of Dilated Cardiomyopathy in Bmi1-null mice, we set out to identify differentially expressed genes by massively parallel sequencing of heart samples from Bmi1f/f;αMHCTM-Cretg/+ mice versus αMHCTM-Cretg/+ control mice (17 weeks postinduction).

LncRNA expression data from human plasma of control donors and chronic HF patients

Project description:There are a lot of non-coding RNAs in human plasma. Some of them could be a biomarker of diseases. We used microarrys to detect lncRNAs in plasma of 10 control subjects and 10 heart failure (HF) patients diagnosed with dilated cardiomyopathy (DCM) and we identified distinct classes of dysregulated lncRNAs.

Dilated Cardiomyopathy in Dobermans and Boxers

Project description:This study attempts at investigating the changes in cardiac gene expression that occur in Dilated Cardiomyopathy (DCM). DCM in Dobermans and Boxers are the focus of this study. Control heart tissue as well as Pacing tissue used is from mongrel dogs. Keywords: control vs pacing vs disease; strain specific disease 3 Dobermans-DCM, 4 Boxers-DCM, 3 mongrels-control and 3 mongrels-pacing

Transcription profiling of human heart with heart failure due to ischemic cardiomyopathy or dilated cardiomyopathy

Project description:End stage heart failure due to ischemic cardiomyopathy (ICM) and dilated cardiomyopathy (DCM) have similar characteristics, enlargement of the ventricles, relatively thin-walled ventricle, which leads to a limited contraction force and blood loading. Nevertheless, the response for present therapeutics is very variable and the prognosis is still very bad for ICM and DCM in general. Thus, the ability to differentiate the etiologies of heart failure based structural and physiological changes of the heart would be a step forward to enhance the specificity and the success of given therapy.

Expression data from human heart

Project description:Global gene expression is altered in heart failure. This syndrome can be caused by cardiovascular diseases, including dilated cardiomyopathy (DCM), ischemic cardiomyopathy (ICM), hypertrophic cardiomyopathy, viral or toxic myocarditis, hypertension, and valvular diseases. We used microarrays to evaluate the impact of heart failure on human nucleocytoplasmic transport-related genes examining simultaneoulsly both dilated and ischemic human cardiomyopathies compared to normal hearts.

Sex differences during acute myocarditis against coxsackievirus B3 (CVB3)-induced myocarditis (10 dpi) and chronic myocarditis/dilated cardiomyopathy (DCM) against CVB3-induced myocarditis (90 dpi)

Project description:Men are at an increased risk of dying from heart failure caused by inflammatory heart diseases such as atherosclerosis, myocarditis and dilated cardiomyopathy (DCM). We previously showed that immune responses in the heart are phenotypically distinct in male compared to female mice 10 days after infection resulting in severe DCM in males. Groups consisted of Infected Males, Infected Females, Uninfected Males and Uninfected females. There are 3 mice per group. A total of 12 samples were analyzed in this experiment (12 for 10 dpi and 12 for 90 dpi).

Expression data from patient iPSC and iPSC-derived cardiomyocytes

Project description:Dilated cardiomyopathy (DCM) is the leading cause of heart failure and transplantation worldwide. We used iPSCs to model this disease and compared gene expression change before and after gene therapy of cardiomyocytes derived from DCM-specific iPSCs. We used microarrays to detail the global gene expression of patient specific iPSCs, iPSC-derived cardiomyocytes and its response to gene therapy. Skin fibroblasts and iPSCs derived from a family exhibiting familial dilated cardiomyopathy and H7 human ESCs were subjected to RNA extraction and hybridization on Affymetrix microarrays.Global gene expression pattern were compared and analyzed. Cardiomyocytes derived from iPSCs generated from this DCM family were treated with or without adenoriral Serca2a and subjected to RNA extraction and hybridization on Affymetrix microarrays. Global gene expression pattern were compared and analyzed.

LncRNA DCRT protects against dilated cardiomyopathy via binding to PTBP1 (Iso-seq)

Project description:Dilated cardiomyopathy (DCM) is characterized by left ventricular dilation and continuous systolic dysfunction. Mitochondrial impairment is critical in DCM, but the mechanism remains to be elucidated. Here we explored the cardio-protective role of a heart-enriched long non-coding RNA (lncRNA), named dilated cardiomyopathy repressive transcript (DCRT), via maintaining mitochondrial function. We found the lncRNA DCRT was highly enriched in normal heart tissue and its expression was significantly down-regulated in myocardium of DCM patients. DCRT knockout in mice spontaneously developed cardiac dysfunction with cardiac enlargement and mitochondrial impairment. DCRT transgenic or overexpressed mice attenuated cardiac dysfunction induced by transverse aortic constriction (TAC) treatment.
