MetabolomicsButyrate ameliorate doxorubicin-induced heart failure via microbiota/ metabolites-gut-Heart axis
Doxorubicin(DOX) is widely used in cancer chemotherapy with a limitation of DOX-induced cardiotoxicity(DIC),resulting in heart failure(HF).HF accompanies by gut microbial dysbiosis.However,how gut microbiota regulate DIC-induced heart failure (DIHF)remains unclear.Here, we established a susceptibili...

MetabolomicsDiscovery and validation of potential serum biomarkers for heart failure by untargeted metabolomics

Detection of biomarkers was extremely important for the early diagnosis, prognosis and therapy optimization of diseases. The purpose of this study was to investigate the differences in serum metabolites between patients with heart failure (HF) and healthy controls (HC), and to diagnose HF qualita...

MetabolomicsEvidence of altered fatty acid metabolism in dogs with naturally occurring valvular heart disease and congestive heart failure

INTRODUCTION: Myxomatous mitral valve disease (MMVD) is the most common cardiac condition in adult dogs. The disease progresses over several years and affected dogs may develop congestive heart failure (HF). Research has shown that myocardial metabolism is altered in cardiac dise...

MetabolomicsLandscape of gut microbiota and metabolites and their interaction in comorbid heart failure and depressive symptoms: a random forest analysis study

Depression is an individual risk factor for poor prognosis in patients with heart failure (HF). Recent studies show that gut microbiota and metabolites have critical role in comorbid HF and depressive symptoms. We recruited 95 subjects including 35 HF patients with depressive symptoms (HF-DS), 36...

TranscriptomicsProgression of heart failure induced by tachycardia
Analysis of changes of gene expression profiles in the left ventricle (LV) during the progression of heart failure (HF) in the canine tachypacing induced HF model. Gene expression profiling was performed on samples collected at different time points representing various stages of LV dysfunction, i.e...

ProteomicsCardiomyocyte Contractile Impairment in Heart Failure Results from Reduced BAG3-mediated Sarcomeric Protein Turnover
The association between reduced myofilament force-generating capacity (Fmax) and heart failure (HF) is clear, however the underlying molecular mechanisms are poorly understood. Here, we show impaired Fmax arises from reduced BAG3-mediated sarcomere turnover. Myofilament BAG3 expression decreases in ...

TranscriptomicsTranscription profiling of rat 3 months old male Wistar animals by aorto-caval fistula reveals alterations in systemic substrate metabolism in rat volume-overload model of chronic heart failure
Abnormalities in metabolism of energetic substrates may play a role in progression of chronic heart failure (HF). The goal of the study was to examine the extent and mechanisms of metabolic alterations in rat model of chronic HF due to volume overload. Volume overload was induced in 3 months old mal...

TranscriptomicsBET Bromodomains Mediate Transcriptional Pause Release in Heart Failure [Mouse Heart Expression]
Heart failure (HF) is driven via interplay between master regulatory transcription factors and dynamic alterations in chromatin structure. While pathologic gene transactivation in this context is known to be associated with recruitment of histone acetyl-transferases and local chromatin hyperacetylat...

TranscriptomicsTranscriptome analysis of diabetic and non diabetic patients affected by post-ischemic heart failure
Increased morbidity and mortality associated with post-ischemic heart failure (HF) in diabetic patients underscore the need for a better understanding of the underlying molecular events. Indeed, effective HF therapy in diabetic patients requires a complex strategy encompassing the development of imp...
