Increasing evidence shows that C-reactive protein (CRP) is not only an inflammatory biomarker but also an important risk factor associated with ageing-related diseases including cardiovascular disease, hypertension, diabetes mellitus, and kidney disease. Recent studies have demonstrated that CRP is pathogenic in a number of diseases including hypertensive cardiovascular and kidney complications, diabetic nephropathy, and acute and chronic kidney diseases. It is well known that CRP binds its receptor, CD32/CD64, to induce the process of inflammation by activating the NF-κB signalling pathway...

Speranza Rubattu, Filippos Triposkiadis
The natriuretic peptide (NP) system, which includes atrial natriuretic peptide, B-type natriuretic peptide, and C-type natriuretic peptide, has an important role in cardiovascular homeostasis, promoting a number of physiological effects including diuresis, vasodilation, and inhibition of the renin-angiotensin-aldosterone system. Heart failure (HF) is associated with defects in NP processing and synthesis, and there is a strong relationship between NP levels and disease state. NPs are useful biomarkers in HF, and their use in diagnosis and evaluation of prognosis is well established, particularly in patients with HF with reduced ejection fraction (HFrEF)...

Sustained cardiac hypertrophy (CH) is related to a variety of physiological as well as pathological stimuli and eventually increases the risk of heart failure. HOTAIR has been identified as a competing endogenous RNA in multiple human biological processes. Whether lncRNA-HOTAIR is involved in the progress of CH and how it works still remain unknown. Herein, we found that HOTAIR was down-regulated, while miR-19 was up-regulated in both heart tissues from TAC-operated mice in vivo and cultural cardiomyocytes treated with Ang-II in vitro by real-time PCR...

The adult heart retains a limited ability to regenerate in response to injury. Although exercise can reduce cardiac ischaemia/reperfusion (I/R) injury, the relative contribution of cardiac cell proliferation including newly formed cardiomyocytes remains unclear. A 4-week swimming murine model was utilized to induce cardiac physiological growth. Simultaneously, the antineoplastic agent 5-fluorouracil (5-FU), which acts during the S phase of the cell cycle, was given to mice via intraperitoneal injections. Using EdU and Ki-67 immunolabelling, we showed that exercise-induced cardiac cell proliferation was blunted by 5-FU...

During heat waves, significant mortality and morbidity occurs in elderly populations due to heat-stress and dehydration. The dehydration is primarily attributable to inadequate water intake caused by dysfunction of the central nervous system mechanisms controlling thirst. The phenomenon of a reduced thirst in response to dehydration in aging was first observed decades ago and has been examined extensively since. The reduced thirst and ingestive behavior have been reported consistently in response to hyperosmotic stimuli, hypovolemic stimuli and dehydration in both elderly humans and animal models of aging...

The maintenance of plasma sodium concentration within a narrow limit is crucial to life. When it differs from normal physiological patterns, several mechanisms are activated in order to restore body fluid homeostasis. Such mechanisms may be vegetative and/or behavioral, and several regions of the central nervous system (CNS) are involved in their triggering. Some of these are responsible for sensory pathways that perceive a disturbance of the body fluid homeostasis and transmit information to other regions...

The endothelium, which is at the interface between circulating blood and the vascular wall, comprises a simple squamous layer of cells that lines the inner surface of all blood vessels. Endothelial cells are highly metabolically active and play an important role in many physiological functions, including control of vasomotor tone, blood cell trafficking, vascular permeability, and maintenance of vascular integrity (Mensah, Vascul Pharmacol 46(5):310-314, 2007; Yetik-Anacak and Catravas, Vascul Pharmacol 45(5):268-276, 2006)...

The burden of cardiovascular diseases (CVD) in general and heart failure (HF) in particular continues to increase worldwide. CVD are major contributors to death and morbidity and recognized as important drivers of healthcare expenditure. Chronic overactivity of the renin-angiotensin-aldosterone system (RAAS) plays a key role in human hypertension and HF pathophysiology. RAAS is fundamental in the overall regulation of cardiovascular homeostasis through the actions of hormones, which regulate vascular tone, and specifically blood pressure through vasoconstriction and renal sodium and water retention...

SCOPE: The flavanol (-)-epicatechin (Epi) has cardioprotective effects and improves physical capacity in normal mice. In addition, Epi increases nitric oxide (NO) production by activation of both PI3K/Akt or Ca(2+) /CaMI/CaMKII (where Akt is protein kinase B; PI3K is phosphoinositide 3-kinase; CaMI is calmodulin; CaMKII is Ca(2+) /calmodulin-dependent protein kinase II) signaling pathways, which have been associated with physiological and pathological cardiac hypertrophy, respectively...

OBJECTIVE: Obese persons have low circulating natriuretic peptide (NP) concentrations. It has been proposed that this 'natriuretic handicap' could play a role in obesity-related hypertension. The normal physiological response of the NP system to an increase in blood pressure (BP) is an increase in NP secretion with concomitant higher circulating NP concentrations. In this study, we investigated whether higher BP would also be related to higher circulating NP concentrations in obese men; furthermore, we verified that BP had affected the hearts of our study participants, by determining left ventricular mass (LVM)...

Depletion of mitochondrial endo/exonuclease G-like (EXOG) in cultured neonatal cardiomyocytes stimulates mitochondrial oxygen consumption rate (OCR) and induces hypertrophy via reactive oxygen species (ROS). Here, we show that neurohormonal stress triggers cell death in endo/exonuclease G-like-depleted cells, and this is marked by a decrease in mitochondrial reserve capacity. Neurohormonal stimulation with phenylephrine (PE) did not have an additive effect on the hypertrophic response induced by endo/exonuclease G-like depletion...

Toxic effects of copper on aquatic organisms in polluted water bodies have garnered particular attention in recent years. Microalgae play an important role in aquatic ecosystems, and they are sensitive to heavy metal pollution. Thus, it is important to clarify the mechanism of copper toxicity first for ecotoxicology studies. In this study, the physiological, biochemical and gene expression characteristics of a model green microalga, Chlamydomonas reinhardtii, with 0, 50, 150 and 250 μM copper treatments were investigated...

Atrial natriuretic peptide (ANP)-mediated natriuretic response is a well-established cardiac endocrine function. Corin is a transmembrane protease that activates ANP in the heart. Corin expression has been detected in non-cardiac tissues including the kidney. Here we examined corin, pro-ANP/ANP and natriuretic peptide receptor-A (NPR-A) expression in human renal segments. By immunostaining and in situ hybridization, we found similar corin, pro-ANP/ANP and NPR-A protein and mRNA expression in human renal segments...
