MetabolomicsGRSF1 Protects Against Heart Failure by Maintaining BCAA Homeostasis

BACKGROUND: Imbalances in cardiac branched-chain amino acid (BCAA) metabolism and mitochondrial homeostasis are implicated in the onset and development of heart failure. However, the mechanisms triggering the downregulation of cardiac BCAA metabolism in heart failure remain unclear. Here, we iden...

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...

MetabolomicsSevere hyperchylomicronemia sensitizes the heart to pathological remodeling: evidence from GPIHBP1 deficient mice
Abstract Aim: Circulating triglyceride and triglyceride-rich lipoprotein (TRL) accumulation is increasingly recognized as a residual atherosclerotic risk, but their specific effect in cardiac remodeling and heart failure (HF) remain largely unexplored. Here we investigated this issue in Gpihbp1 knoc...

MetabolomicsMild cold exposure mitigates ischemic heart injury through indole-3-acetamide–AHR-mediated SMAD2 proteolysis

Ambient temperature profoundly influences organismal metabolism, physiology, and disease. While cold exposure is a well-recognized risk factor for the onset of myocardial infarction (MI), its impact on the injured heart after MI remains unexplored. Here,&nb...

TranscriptomicsSingle cell RNA-Seq of the mouse heart in response to chronic stress
We characterized single-cell transcriptional profiles of heart ventricles of C57BL/6J female and male mice subjected to a chronic stress, two weeks of continuous administration of Angiotensin II. The cell preparation we sequenced consisted of metabolically active, nucleated non-myocyte cells which ...

TranscriptomicsGene expression profiles based on Pulmonary Artery Pressures in Pulmonary Fibrosis
Pulmonary Hypertension (PH) is a frequent complication of Pulmonary Fibrosis (PF). PH can be seen in PF in the abscence of hypoxemia, irrespective of the degree of fibrosis. At the same time, a consistent number of patients with advanced PF never develop PH. The pathogenesis of PH secondary to PF re...

TranscriptomicsCardiac 12/15-lipoxygenase-induced inflammation is involved in heart failure
To identify a novel target for the treatment of heart failure, we examined gene expression in the failing heart. Among the genes analyzed, 12/15 lipoxygenase (12/15-LOX) was markedly up-regulated in heart failure. To determine whether increased expression of 12/15-LOX causes heart failure, we establ...

TranscriptomicsTranscription profiling of hearts from mice heterozygous for Gata4 mutation (G4D) to investigate the significance of Gata4 in regulating postnatal heart function and in regulating the hypertrophic response of the heart to pathological stress.
An important event in the pathogenesis of heart failure is the development of pathological cardiac hypertrophy. In cultured cardiac cardiomyocytes, the transcription factor Gata4 is required for agonist-induced cardiomyocyte hypertrophy. We hypothesized that in the intact organism Gata4 is an import...

ProteomicsChronic Aicar Treatment Identifies Sex-specific Phenotypes in the Aging Mouse Heart
Heart failure represents a leading cause of mortality in the elderly population. Although aging features include diastolic dysfunction and interstitial fibrosis in both males and females, it becomes increasingly apparent that aged male and female hearts are phenotypically different. There were funda...

ProteomicsDefining the cardiac fibroblast secretome in the post-MI heart in vivo
Cardiac fibrosis is a common feature of ischemic heart disease and cardiac fibroblasts (CF) are key players in cardiac remodeling of the injured heart after myocardial infarction (MI). Fibrosis increases myocardial stiffness, thereby impairing cardiac function, which ultimately progresses to end-sta...
