MetabolomicsDeletion of Gja1 in myocardium emerges ventricular arrhythmia and tachycardia by reprogramming proline metabolism
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...

MetabolomicsUntargeted Metabolomic Profiling of Left Ventricular Myocardium in a Mouse Model of Diabetic Cardiomyopathy
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. ...

TranscriptomicsMutations in the NOTCH pathway regulator MIB1 cause left ventricular noncompaction cardiomyopathy
Left ventricular noncompaction (LVNC) Causes prominent ventricular trabeculations and reduces cardiac systolic function. The clinical presentation of LVNC ranges from asymptomatic to heart failure. We show that germline mutations in human MIB1 (mindbomb homolog 1), which encodes an E3 ubiquitin liga...

TranscriptomicsTranscription profiling of right ventricule from arrhythmogenic heterozygous plakoglobin deficient mice undergone endurance training to identify transcriptional responses to training.
Endurance training accelerated development of right ventricular dysfunction and arrhythmias in plakoglobin+/- mice. Histology and electron microscopy did not identify right ventricular abnormalities. To identify differences in the transcriptional response to training gene expression profiling was pe...

TranscriptomicsPrdm16 newborn mouse (ventricular zone) VZ cells microarray
As Prdm16 deficiency reduces self-renewal potential and depletes neural stem cells in culture we decided to investigate the underlying molecular mechanisms of the neural stem cells depletion in the Prdm16 deficient animals. For the experiment we used Prdm16Gt(OST67423)Lex (Prdm16LacZ) genetrap mice ...

TranscriptomicsComparison of neonatal and adult rat ventricular cardiomyocytes
We addressed the question of which protein kinases are expressed in cardiomyocytes. We assessed the changes during postnatal development, comparing profiles in rat neonatal ventricular cardiomyocytes (NVMs) with adult ventricular cardiomyocytes (AVMs). Neonatal and adult rat ventricular cardiomyocyt...

TranscriptomicsMolecular Remodeling of Ion Channels in Human Atrial and Ventricular Myocytes Associated with Ischemic Cardiomyopathy
Ischemic cardiomyopathy (ICM) leads to congestive heart failure and can cause sudden cardiac death due to arrhythmia. Existing molecular knowledge base of ICM is rudimentary because of lack of specific attribution to cell type and function. This study was designed to investigate cell-specific molecu...
