MetabolomicsActivation of imprinted gene Pw1 promotes cardiac fibrosis after ischemic injury

Cardiac fibrosis, characterized by excessive extracellular matrix (ECM) deposition in the myocardium, is a critical target for heart disease treatments. Pw1 (paternally expressed gene 3) is an imprinted gene expressed from the paternally allele, and de novo purine biosynthesis (DNPB) is a crucial...

TranscriptomicsCardiogenic genes expressed in cardiac fibroblasts contribute to heart development and repair
Cardiac fibroblasts are critical to proper heart function through multiple interactions with the myocardial compartment. Loosely defined based on their mesenchymal origin, capacity to adhere to plastic and to secrete extracellular matrix, cardiac fibroblasts have been largely neglected due to hetero...

TranscriptomicsmicroRNA sequencing in rat cardiac fibroblasts and fibroblast-derived exosomes
We found that cardiac fibroblasts produce and secrete exosomes. miRNA profiling and TaqMan qRT-PCR experiments identified miR-21 expression to be higher in cardiac fibroblasts compared to those of miR-21*, whereas in exosomes miR-21* expression was higher compared to miR-21. The purpose of the stud...

ProteomicsTranscriptome and proteome profiling of activated cardiac fibroblasts supports target prioritization in cardiac fibrosis
Activated cardiac fibroblasts (CF) play a central role in cardiac fibrosis, a condition associated with most cardiovascular diseases. Conversion of quiescent into activated CF sustains heart integrity upon injury. However, permanence of CF in active state inflicts deleterious heart function effects....

ProteomicsDefining the cardiac fibroblast secretome - in vitro stimulation
Cardiac fibroblasts (CF) are key players in cardiac remodeling, but their intercellular communication is only incompletely understood. Here we analyzed the secretome of cardiac fibroblasts (cCF) after stimulation with TGFß or hypoxia and respective non-treated controls using metabolic labeling combi...

TranscriptomicsGene expression in mouse embyonic cardiomyocytes, fibroblasts and adult cardiac fibroblasts
Growth and expansion of ventricular chambers is essential during cardiogenesis and is achieved by proliferation of cardiac progenitors that are not fully differentiated. Disruption of this process can lead to prenatal lethality. In contrast, adult cardiomyocytes achieve growth through hypertrophy ra...

ProteomicsDefining the cardiac fibroblast secretome
Cardiac fibroblasts (CF) are key players in cardiac remodeling, but their intercellular communication is only incompletely understood. Here we analyzed the secretome of healthy cardiac fibroblasts (cCF) and cardiac fibroblasts isolated from post-myocardial infarction (postMI) hearts) using metabolic...

TranscriptomicsTranscriptome modulation of ventricles, cardiomyocytes and cardiac fibroblasts during postnatal mouse development
During development the fetal heart undergoes a rapid and dramatic transition to adult function through transcriptional and post-transcriptional mechanisms, including alternative splicing (AS). We performed deep RNA-sequencing for high-resolution analysis of transcriptome changes during postnatal mou...

ProteomicsCardiomyocytes regulate cardiac fibroblast activation and oxidative stress via CK2 signaling
Secretome-mediated signaling from human iPSC-derived cardiomyocytes (TGFβ induced dysfunction) to primary human cardiac fibroblasts was investigated to identify downstream regulators of fibrosis. Quantitative proteomic profiling revealed a dynamic reprogramming of fibroblast global proteome, with dy...

TranscriptomicsReversible and irreversible differentiation of cardiac fibroblasts
Aim: Differentiation of cardiac fibroblasts (Fb) into myofibroblasts (MyoFb) is responsible for connective tissue buildup in myocardial remodeling. We examined reversibility of MyoFb differentiation. Methods and Results: Adult rat cardiac Fb were cultured on a plastic substratum providing mechanical...
