MetabolomicsComprehensive Metabolic Profiling of Age-Related Mitochondrial Dysfunction in the High-Fat-Fed ob/ob Mouse Heart
The ectopic deposition of fat is thought to lead to lipotoxicity and has been associated with mitochondrial dysfunction and diabetic cardiomyopathy. We have measured mitochondrial respiratory capacities in the hearts of ob/ob and wild-type mice on either a regular chow (RCD) or high-fat (HFD) diet a...

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...

MetabolomicsFOXK1 and FOXK2 Promote Cardiomyocyte Proliferation and Heart Regeneration
Promoting the proliferation of endogenous cardiomyocytes represents a promising strategy for treating cardiac injuries. Identifying key factors that regulate cardiomyocyte proliferation can advance the development of novel therapies for heart regeneration. Here we identify that FOXK1 and FOXK2 act a...

MetabolomicsGut microbiota derived metabolite protects against heart failure with preserved ejection fraction

Targeted metabolomics analysis was performed to examine the differences in metabolite in fecal samples of heart failure with preserved ejection fraction (HFpEF) and control mice.

GenomicsLarge-Scale Discovery of Enhancers from Human Heart Tissue
Development and function of the human heart depend on the dynamic control of tissue-specific gene expression by distant-acting transcriptional enhancers. While large numbers of heart enhancers have been identified using the mouse as a model system, many of these regulatory sequences are poorly cons...

MetabolomicsPyruvate metabolism enzyme Dlat induces mitochondria protein hyperacetylation to limit fatty acid oxidation in the HFpEF heart

Increased protein acetylation is frequently observed in the failing heart, including in hearts with heart failure with preserved ejection fraction (HFpEF). However, the role of protein acetylation in cardiac metabolic impairments during the pathogenesis of HFpEF remains insufficiently investigate...

MetabolomicsMetabolomics of the interaction between PPAR-alpha and age in the PPAR-alpha-null mouse (NMR assay)
Regulation between the fed and fasted state in mammals is partially controlled by peroxisome proliferator activated receptor-alpha (PPAR-alpha). Expression of the receptor is high in liver, heart and skeletal muscle, but decreases with age. A combined 1H NMR spectroscopy and GC-MS metabolomic approa...

TranscriptomicsmRNA sequencing of two brain regions (prefrontal cortex and hippocampus) and left myocardial tissue in mice with chronic heart failure vs. sham-operated control mice
After induction of ischemic chronic heart failure (CHF), mice exhibited depression-like behavior, in terms of increased anhedonia, and decreased both exploratory activity and interest in novelty. On histology, ischemic CHF mice showed no alterations in overall cerebral morphology. To further evaluat...

MetabolomicsMetabolomic landscape of fetal organs development during late gestation in mice
Metabolism is the critical basis for mammalian physiological functions. The systematic metabolic characteristics of major organ development during late gestation to adapt to postnatal environmental changes are still absent. Here, we detected metabolic patterns of the mouse fetal organs, including th...
