: We assessed the effects of liraglutide treatment on five cardiovascular risk biomarkers, reflecting different pathophysiology: 1) Tumour necrosis factor-alpha (TNF-alpha); 2) Soluble urokinase plasminogen activator receptor (suPAR); 3) Mid-regional pro-adrenomedullin (MR-proADM); 4) Mid-regional pro-atrial natriuretic peptide (MR-proANP); and 5) Copeptin, in type 2 diabetes patients with albuminuria. In a randomised, double-blind, placebo-controlled, cross-over trial we enrolled patients with type 2 diabetes and persistent albuminuria (urinary albumin-to-creatinine ratio (UACR) > 30 mg/g) and estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1...

PURPOSE: Cisplatin is an effective chemotherapeutic agent used to treat a variety of malignant tumors. The major toxicity associated with cisplatin treatment is granulocytopenia. C-type natriuretic peptide (CNP), a member of the natriuretic peptide family, protects against toxicity in many organs, including the heart, blood vessels, lung, and kidney. The objective of this study was to investigate the myeloprotective effects of CNP in a mouse model of cisplatin-induced granulocytopenia...

The abundance of epicardial adipose tissue (EAT) is associated with atrial fibrillation (AF), the most frequent cardiac arrhythmia. However, both the origin and the factors involved in EAT expansion are unknown. Here, we found that adult human atrial epicardial cells were highly adipogenic through an epithelial-mesenchymal transition both in vitro and in vivo. In a genetic lineage tracing the WT1(CreERT2+/-)Rosa(tdT+/-) mouse model subjected to a high-fat diet, adipocytes of atrial EAT derived from a subset of epicardial progenitors...

Activation of resident and infiltrating immune cells is a central event in training adaptation and other contexts of skeletal muscle repair and regeneration. A precise orchestration of inflammatory events in muscle fibers and immune cells is required after recurrent contraction-relaxation cycles. However, the mechanistic aspects of this important regulation remain largely unknown. We now demonstrate that besides a dominant role in controlling cellular metabolism, the peroxisome proliferator-activated receptor γ co-activator 1α (PGC-1α) also has a profound effect on cytokine expression in muscle tissue...

BACKGROUND: Olmesartan and azilsartan, angiotensin II receptor blockers (ARBs), are expected to decrease blood pressure more than the other ARBs. We conducted randomized-controlled trials to compare the practical efficacy of olmesartan with azilsartan. METHODS: Eighty-four patients treated with the conventional ARBs for more than 3 months were assigned randomly to receive either 20 mg of olmesartan (olmesartan medoxomil, OL group) or 20 mg of azilsartan (azilsartan, not azilsartan medoxomil, AZ group) once daily for 16 weeks...

BACKGROUND: Plasma concentrations of natriuretic peptides decline with obesity in patients with heart failure. Whether this is true for other biomarkers is unknown. We investigated a wide range of biomarker profiles in acute heart failure across the body mass index (BMI) spectrum. METHODS AND RESULTS: A total of 48 biomarkers, assessing multiple pathophysiological pathways, were measured in 2033 patients included in PROTECT (Placebo-Controlled Randomized Study of the Selective A1 Adenosine Receptor Antagonist Rolofylline for Patients Hospitalized With Acute Decompensated Heart Failure and Volume Overload to Assess Treatment Effect on Congestion and Renal Function), a trial comparing the effects of rolofylline to placebo in patients with acute heart failure...

BACKGROUND: Cardiac troponin I, measured with a high-sensitivity assay (hs-TnI), is well-established for risk prediction in acute coronary syndromes. However, its prognostic role in stable atherosclerotic disease, particularly for future myocardial infarction (MI), is less well defined. METHODS: We measured hs-TnI (Abbott ARCHITECT) in 15833 patients with prior MI, ischemic stroke, or peripheral arterial disease from the placebo-controlled Thrombin Receptor Antagonist in Secondary Prevention of Atherothrombotic Ischemic Events (TRA 2°P)-Thrombolysis in Myocardial Infarction (TIMI) 50 trial of the platelet inhibitor vorapaxar, excluding patients with recent MI (<30 days)...

Mammalian spermatozoa undergo selective movement along the isthmus of the oviduct to the ampulla during ovulation, which is a prerequisite for fertilization. The factor(s) that involves in selective spermatozoa movement is still unknown. In this study, we found that the oviductal epithelium in mouse ampulla expressed high levels of natriuretic peptide type C (NPPC) in the presence of ovulated oocyte-cumulus complexes (OCCs). Spermatozoa expressed NPPC receptor natriuretic peptide receptor 2 (NPR2, a guanylyl cyclase) on the midpiece of flagellum...

We previously reported the secretion of C-type natriuretic peptide (CNP) from vascular endothelial cells and proposed the existence of a vascular natriuretic peptide system composed of endothelial CNP and smooth muscle guanylyl cyclase-B (GC-B), the CNP receptor, and involved in the regulation of vascular tone, remodeling, and regeneration. In this study, we assessed the functional significance of this system in the regulation of blood pressure in vivo using vascular endothelial cell-specific CNP knockout and vascular smooth muscle cell-specific GC-B knockout mice...

BACKGROUND: Pulmonary fibrosis is a life-threatening disease characterized by progressive dyspnea and worsening pulmonary function. Atrial natriuretic peptide (ANP), a heart-derived secretory peptide used clinically in Japan for the treatment of acute heart failure, exerts a wide range of protective effects on various organs, including the heart, blood vessels, kidneys, and lungs. Its therapeutic properties are characterized by anti-inflammatory and anti-fibrotic activities mediated by the guanylyl cyclase-A (GC-A) receptor...

BACKGROUND: The prognosis of heart failure patients with reduced ejection fraction (HFrEF) in Japan remains poor, although there is growing evidence for increasing use of evidence-based pharmacotherapies in Japanese real-world HF registries. Sacubitril/valsartan (LCZ696) is a first-in-class angiotensin receptor neprilysin inhibitor shown to reduce mortality and morbidity in the recently completed largest outcome trial in patients with HFrEF (PARADIGM-HF trial). The prospectively designed phase III PARALLEL-HF (Prospective comparison of ARNI with ACE inhibitor to determine the noveL beneficiaL trEatment vaLue in Japanese Heart Failure patients) study aims to assess the clinical efficacy and safety of LCZ696 in Japanese HFrEF patients, and show similar improvements in clinical outcomes as the PARADIGM-HF study enabling the registration of LCZ696 in Japan...

The Amur ide (Leuciscus waleckii) is a cyprinid fish that is widely distributed in Northeast Asia. The Lake Dali Nur population inhabits one of the most extreme aquatic environments on Earth, with an alkalinity up to 50 mmol/L (pH 9.6), thus providing an exceptional model with which to characterize the mechanisms of genomic evolution underlying adaptation to extreme environments. Here, we developed the reference genome assembly for L. waleckii from Lake Dali Nur. Intriguingly, we identified unusual expanded long terminal repeats (LTRs) with higher nucleotide substitution rates than in many other teleosts, suggesting their more recent insertion into the L...

It has been known since the 1990s that long-term morbidity and mortality is improved in patients with heart failure with reduced ejection fraction (HFrEF) by treatments that target the renin-angiotensin-aldosterone system (RAAS). It has also long been thought that enhancement of the activity of natriuretic peptides (NPs) could potentially benefit patients with HFrEF, but multiple attempts to realize this benefit had failed over the years - until 2014, when a large, phase III, randomized, controlled clinical trial (PARADIGM-HF) was completed comparing sacubitril/valsartan with enalapril, a well-established treatment for HFrEF...

Brain natriuretic peptide (BNP) exerts its functions through NP receptors. Recently, BNP has been shown to be involved in a wide range of functions. Previous studies reported BNP expression in the sensory afferent fibers in the dorsal horn (DH) of the spinal cord. However, BNP expression and function in the neurons of the central nervous system are still controversial. Therefore, in this study, we investigated BNP expression in the rat spinal cord in detail using reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry...

Acromesomelic dysplasia, type Maroteaux is a disorder characterized by disproportionate short stature predominantly affecting the middle and distal segments of the upper and lower limbs. It is an autosomal recessive disorder due to mutation in NPR2 gene which impairs skeletal growth. To screen the mutations in the gene NPR2, all of its coding exons and splice junction sites were PCR amplified from genomic DNA of affected individuals of four families and sequenced. Four homozygous mutations in four different families were identified...
