BACKGROUND
Ceruloplasmin antioxidant function is mainly related to its ferroxidase I (FeOxI) activity, which influences iron-dependent oxidative and nitrosative radical species generation. Peroxynitrite, whose production is increased in heart failure (HF), can affect ceruloplasmin antioxidant
BACKGROUND
Cardiac metastases from papillary thyroid carcinoma are very uncommon. Their incidence is rising due to improvements in survival and diagnosis; nevertheless, our patient is the fourth case reported up to date. There are no clinical trials available in this scenario. Therefore, treatment
BACKGROUND
Chronic heart failure (CHF) induces endothelial dysfunction characterized by a decrease in nitric oxide (NO) production in response to flow (flow-mediated dilatation [FMD]). Because activation of endothelial NO synthase (eNOS) by flow requires tyrosine phosphorylation, we tested whether
Soluble fms-like tyrosine kinase-1 (sFlt-1), an endogenous inhibitor of vascular endothelial growth factor and placental growth factor, is involved in the pathogenesis of cardiovascular disease. However, the significance of sFlt-1 in heart failure has not been fully elucidated. We found that sFlt-1
BACKGROUND
Fungal secondary metabolites are important sources for the discovery of new pharmaceuticals, as exemplified by penicillin, lovastatin and cyclosporine. Searching for secondary metabolites of the fungi Metarhizium spp., we previously identified tyrosine betaine as a major
Impairment of baroreflex function is associated with the progression of chronic heart failure (CHF) and a poor prognosis. The baroreflex desensitization in CHF is at least partly the result of central neuronal network dysfunction. The dorsal medial nucleus tractus solitarius (dmNTS) has long been
Few systematic trials have studied metastatic tumors to the heart and there are currently no guidelines for the treatment of heart metastases and its associated symptoms. This article presents the first known case of effective pharmacological treatment of heart failure due to metastases of renal
OBJECTIVE
We sought to evaluate placental growth factor (PlGF) and soluble Fms-like tyrosine kinase 1 (sFlt-1) as clinical biomarkers in chronic heart failure (HF).
BACKGROUND
Vascular remodeling is a crucial compensatory mechanism in chronic HF. The angiogenic ligand PlGF and its target receptor
A systematic review and meta-analysis was conducted to determine the relative risk (RR) of congestive heart failure (CHF) associated with approved multi-targeted vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKI). Eligible studies included randomized trials
BACKGROUND
AXL is a membrane receptor tyrosine kinase highly expressed in the heart and has a conspicuous role in cardiovascular physiology. The role of AXL in heart failure (HF) has not been previously addressed.
RESULTS
AXL protein was enhanced 6-fold in myocardial biopsies of end-stage HF
BACKGROUND
Vascular endothelial dysfunction may play an important role in the progression of heart failure (HF). We hypothesize that elevated levels of vascular markers, placental-like growth factor, and soluble Fms-like tyrosine kinase-1 (sFlt-1) are associated with adverse outcomes in patients
Protein tyrosine phosphatase 1B (PTP1B) regulates tyrosine kinase receptor-mediated responses, and especially negatively influences insulin sensitivity, thus PTP1B inhibitors (PTP1Bi) are currently evaluated in the context of diabetes. We recently revealed another important target for PTP1Bi,
Cardiac angiogenesis is an important determinant of heart failure. We examined the hypothesis that protein tyrosine phosphatase (PTP)-1B, a negative regulator of vascular endothelial growth factor (VEGF) receptor-2 activation, is causally involved in the cardiac microvasculature rarefaction during
OBJECTIVE
Congestive heart failure (CHF) associated with vascular endothelial growth factor tyrosine-kinase inhibitors (VEGFR-TKIs) has emerged as a relevant problem in clinical and scientific communities. We performed an up-to-date, comprehensive meta-analysis to determine the overall incidence and
Receptor tyrosine kinases (RTKs) are implicated in cardiovascular growth and remodelling. We aimed to identify the plasma levels of RTKs and related proteins and their association with haemodynamic alterations in heart failure (HF) and related pulmonary hypertension (PH) following heart
