The cyclin-dependent kinase inhibitor p27(Kip1) arrests cell cycle progression through G1/S phases and is regulated by phosphorylation of serine/threonine residues. Recently, we identified the serine/threonine kinase, KIS, which phosphorylates p27(Kip1) on serine 10 leading to nuclear export of p27(Kip1) and protein degradation. However, the molecular(More)
Sacubitril/valsartan (LCZ696) is a first-in-class angiotensin receptor neprilysin inhibitor (ARNI) and has been recently approved in several countries for the treatment of patients with heart failure and reduced ejection fraction. This was the first study conducted to characterise the pharmacokinetics of LCZ696 analytes (pro-drug sacubitril, active(More)
LCZ696 is a first-in-class angiotensin receptor neprilysin inhibitor in development for treatments of hypertension and heart failure indications. In 3 separate studies, pharmacokinetic drug-drug interactions (DDIs) potential was assessed when LCZ696 was coadministered with hydrochlorothiazide (HCTZ), amlodipine, or carvedilol. The studies used a open-label,(More)
LCZ696, a novel angiotensin receptor neprilysin inhibitor, is in development for the treatment of heart failure. Administration of LCZ696 results in systemic exposure to sacubitril (inactive prodrug of LBQ657), LBQ657 (neprilysin inhibitor), and valsartan (angiotensin II receptor blocker). We investigated the potential effects of age and sex on the(More)
Natriuretic peptides (NP) mediate their effects by activating membrane-bound guanylyl cyclase-coupled receptors A (NPR-A) or B (NPR-B). Whereas the pathophysiological role of NPR-A has been widely studied, only limited knowledge on the cardiovascular function of NPR-B is available. In vitro studies suggest antiproliferative and antihypertrophic actions of(More)
OBJECTIVE Sacubitril/valsartan (LCZ696) provides a novel therapeutic approach of neurohormonal modulation in heart failure via simultaneous inhibition of neprilysin and blockade of the angiotensin II type-1 receptor. This study was conducted to evaluate the effect of food on the oral bioavailability of LCZ696 analytes. MATERIALS AND METHODS This was an(More)
WHAT IS KNOWN AND OBJECTIVE Sacubitril/valsartan (LCZ696) has been recently approved for the treatment of heart failure (HF) patients with reduced ejection fraction. Several HF patients receive statins as co-medication. METHODS Because clearance of statins is meditated via OATP1B1/1B3, the inhibition potential of these transporters by LCZ696 analytes was(More)
OBJECTIVE Recently, deletion of specific genes by so called knock-out techniques has become important for investigating the pathogenesis of various diseases. This form of genetic engineering is widely performed in murine models. There are, however, only a limited number of mouse models available in cardiovascular pathology. The objective of this study,(More)
BACKGROUND The role of angiotensin II type 1 (AT1) and type 2 (AT2) receptors in cardiac hypertrophy and fibrosis is incompletely understood. The availability of AT2 receptor-deficient mice (AT2 -/y) makes it possible to study the effects of AT1 receptors without the confounding influence of AT2 receptor activity. OBJECTIVE To test the hypothesis that the(More)
Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are cardiac hormones that are involved in water and electrolyte homeostasis in heart failure. Although both hormones exert almost identical biological actions, the differential regulation of cardiac ANP and BNP mRNA in compensated and overt heart failure is not known. To study the(More)
