MetabolomicsGut microbiota production of trimethyl-5-aminovaleric acid reduces fatty acid oxidation and accelerates cardiac hypertrophy
Numerous studies found intestinal microbiota alterations which are thought to affect the development of various diseases through the production of gut-derived metabolites. However, the specific metabolites and their pathophysiological contribution to cardiac hypertrophy or heart failure progression ...

MetabolomicsQuantitative metabolomics of plasma and tissue interstitial fluids from mice

This study presents quantitative metabolomic measurements of plasma and tissue interstitial fluids (IF) collected from healthy C57BL/6J mice. Using liquid chromatography–mass spectrometry (LC–MS) and external chemical standards, absolute concentrations were determined for over one hundred polar m...

MetabolomicsDistinct lipid signatures are identified in the plasma of rats with chronic inflammation induced by estradiol benzoate and sex hormones

INTRODUCTION: Prostatitis is likely to occur in younger or middle-aged men, while prostate cancer is likely to occur in older men. Although amino acids and lipids as biomarkers of prostate cancer have been examined using prostate cancer cell lines/tissues, no previous studies hav...

MetabolomicsCyclooxygenase-2, Asymmetric Dimethylarginine, and the Cardiovascular Hazard From Nonsteroidal Anti-Inflammatory Drugs (Murine kidney and plasma UPLC-MS/MS assay)

BACKGROUND: Large-scale, placebo-controlled trials established that nonsteroidal anti-inflammatory drugs confer a cardiovascular hazard: this has been attributed to depression of cardioprotective products of cyclooxygenase (COX)-2, especially prostacyclin. An alternative mechanis...

MetabolomicsUntargeted Metabolomics Reveals a Mild Impact of Remote Ischemic Conditioning on the Plasma Metabolome and α-Hydroxybutyrate as a Possible Cardioprotective Factor and Biomarker of Tissue Ischemia
Remote ischemic conditioning (RIC) is a maneuver by which short non-lethal ischemic events are applied on distant organs or limbs to reduce ischemia and reperfusion injuries caused by e.g. heart attacks. As RIC can be induced using a simple blood pressure cuff e.g. prior to revascularization, it con...

TranscriptomicsMicroarray analysis of the miRNA levels in plasma from healthy donors
To further understanding of mature microRNA in plasma from healthy people, we have employed microRNA microarray as a discovery platform with the potential to identify the plasma microRNA levels of healthy people. Human peripheral blood was drawn from 4 healthy donors, and plasma was obtained by two-...

MetabolomicsUntargeted Plasma Lipidomics Identifies Oxidative Stress and Inflammation Signatures Associated with Recurrent Leg Ulcer Status in Sickle Cell Disease

Leg ulcers are among the most burdensome complications of sickle cell disease (SCD), yet the molecular determinants underlying ulcer susceptibility and recurrence remain incompletely characterized. We performed untargeted plasma lipidomics by LC–MS in 129 individuals with SCD from the REDS-III Br...

ModelsTylutki2017-four-compartment PBPK heart model accounting for cardiac metabolism
In the field of cardiac drug efficacy and safety assessment, information on drug concentration in heart tissue is desirable. Because measuring drug concentrations in human cardiac tissue is challenging in healthy volunteers, mathematical models are used to cope with such limitations. With a goal of ...

TranscriptomicsmiRNA profiling of plasma samples: patients with unstable coronary artery disease and controls
This study describes a circulating miRNA signature of unstable angina (UA), which may be used as a novel biomarker for unstable coronary artery disease (CAD). The Taqman low-density miRNA array were used to identify distinct miRNA expression profiles in the plasma of patients with typical UA and ang...

TranscriptomicsTranscriptomic alterations in Trypanosoma cruzi-infected cardiac myocytes
Trypanosoma cruzi infection is a major cause of cardiomyopathy. Gene profiling studies of hearts from infected mice have revealed prominent changes in gene expression within many functional pathways. This variety of transcriptomic changes in infected mice raises the question of whether gene express...
