This study characterizes metabolic alterations in the left ventricular myocardium of a high-fat diet and streptozotocin-induced mouse model of diabetic cardiomyopathy. Untargeted LC–MS/MS metabolomics was performed using a Vanquish UHPLC system coupled to an Orbitrap Exploris 120 mass spectrometer. ...

Connexin43 (Cx43) is the predominant connexin in working myocardium. Its expression decreases in various cardiovascular diseases, and accompanied by ventricular arrhythmias (VAs). However, molecular mechanisms underlying increased arrhythmogenesis remained unclear. Here we established iPSC-derived c...

This SuperSeries is composed of the following subset Series: GSE35490: Noncoding RNA expression in myocardium from infants with tetralogy of Fallot [miRNA profiling] GSE35776: Noncoding RNA expression in myocardium from infants with tetralogy of Fallot [mRNA profiling] Refer to individual Series
ORGANISM(S): Homo sapiens 
This is the first report characterizing noncoding RNA expression in a congenital heart defect. The striking shift in expression of noncoding RNAs reflects a fundamental change in cell biology, likely impacting expression, transcript splicing and translation of developmentally important genes and pos...

Title: Gene expression profiling of human heart samples: a comparison between normal and hibernating myocardium.
Description: The aim of this project is to investigate the changes in global gene
expression in hibernating,(preserved wall thickness, impaired
contractility at re...

Restoring the regenerative capacity of myocardium, which presents shortly in the newborns but lost in adulthood, is one of the therapeutic options for myocardial repair post various insults. In this work, we performed the phosphoproteomic analysis on neonatal regenerative myocardium and explored the...

Note this data set has identical data files: Files GSM40994.txt and GSM40995.txt. GSE2240 contains two different experimental subsets:; 1) Comparison of atrial and ventricular gene expression (atrial tissue of patients with sinus rhythm vs. human left ventricular non-failing myocardium); The purpose...

Tetralogy of Fallot (TOF) is one of the most common heart defects in children and the underlying mechanisms remain elusive. miRNAs are a recently discovered class of regulators of gene expression and are becoming increasingly recognized as important regulators of heart development and function. The ...

Here, we characterize the transcriptome of the mouse embryonic stem cell line CM7-1 during differentiation into beating cardiomyocytes and compared the gene expression profiles with those from primary adult murine cardiomyocytes and left ventricular myocardium.
