The angiotensin II type 2 receptor (AT2R) exerts vasorelaxant, anti-inflammatory, and antioxidant properties. In obesity, its activation counterbalances the adverse cardiovascular effects of angiotensin II mediated by the AT1R. Preliminary results indicate that it also promotes brown adipocyte differentiation in vitro. Our hypothesis is that AT2R a...
Article
Objective Cardiorenal syndrome type 4 (CRS type 4) is characterized by primary chronic kidney disease (CKD) leading to cardiac dysfunction and an increase in cardiovascular events. There is an unmet need for suitable animal models of CRS to further define the pathogenesis and progression of CRS to test new therapeutic strategies. We aim to determin...

Fibro-adipogenic progenitors (FAPs) play a crucial role in skeletal muscle regeneration, as they generate a favorable niche that allows satellite cells to perform efficient muscle regeneration. After muscle injury, FAP content increases rapidly within the injured muscle, the origin of which has been attributed to their proliferation within the musc...
Article
Full-text available
Arterial stiffness is a major vascular complication of chronic kidney disease (CKD). The development of renal damage, hypertension, and increased pulse wave velocity (PWV) in CKD might be associated with an imbalance in bone morphogenetic proteins (BMP)-2 and BMP-7. Plasma BMP-2 and BMP-7 were determined by ELISA in CKD patients (stages I–III; n =...

Context: Cardiovascular disease (CVD) is one of the leading causes of morbidity and premature mortality across Spain. According to the World Health Organization (WHO), 80% of these premature deaths are preventable by controlling cardiovascular risk factors. Community pharmacists (CPs) are well situated to provide professional educational advice and...
Article
Objective: Patients with chronic kidney disease (CKD) exhibit an elevated cardiovascular risk from the early stages (I-III) with an exponentially increasing risk of cardiovascular death as kidney function worsens. The hypothesis of this study is that there is a imbalance in bone morphogenetic proteins BMP-2 (procalcifying) and BMP-7 (renoprotectiv...
Article
Full-text available
Endothelial adenosine monophosphate-activated protein kinase (AMPK) plays a critical role in the regulation of vascular tone through stimulating nitric oxide (NO) release in endothelial cells. Since obesity leads to endothelial dysfunction and AMPK dysregulation, AMPK activation might be an important strategy to restore vascular function in cardiom...
Article
Full-text available
The aim of this study was to evaluate the effect of Compound 21 (C21), a selective AT2R agonist, on the prevention of endothelial dysfunction, extracellular matrix (ECM) remodeling and arterial stiffness associated with diet-induced obesity (DIO). 5-week-old male C57BL/6J mice were fed a standard (Chow) or high-fat diet (HF) for 6 weeks. Half of th...

Compound 21 (C21), a selective agonist of angiotensin II type 2 receptor (AT2R), induces vasodilation through NO release. Since AT2R seems to be overexpressed in obesity, we hypothesize that C21 prevents the development of obesity-related vascular alterations. The main goal of the present study was to assess the effect of C21 on thoracic aorta endo...
Article
Objective The angiotensin AT2 Receptor (AT2R) is known to form heterodimers with either the Mas (MasR) or the bradykinin B2 receptor (B2R). Compound 21 (C21), a highly selective AT2R agonist, induces vascular relaxation through stimulation of nitric oxide (NO). Since AT2R is overexpressed in obese models, we hypothesize that C21 might prevent the d...
Article
Objective Increased arterial stiffness, as reflected by an increased pulse wave velocity (PWV), is independently associated with a higher risk of cardiovascular morbidity and mortality in obese patients. Obesity is a low grade chronic inflammatory process due to the increase of visceral fat and adipokine overproduction. One of these adipokines, lip...

Fetal undernutrition programs hypertension and cardiovascular diseases, and resistance artery remodeling may be a contributing factor. We aimed to assess if fetal undernutrition induces resistance artery remodeling and the relationship with hypertension. Sprague-Dawley dams were fed ad libitum (Control) or with 50% of control intake between days 11...
Article
Background: Development of albuminuria and arterial stiffness in Munich Wistar Frömter (MWF) rats, a model of chronic kidney disease, is related to alterations in extracellular matrix, increased oxidative stress, and endothelial dysfunction. Finerenone (FIN), a novel, nonsteroidal, potent, and selective mineralocorticoid receptor antagonist, impro...
Article
Full-text available
The experimental approach for the study of cardiometabolic disorders requires the use of animal models fed with commercial diets whose composition differs notably, even between diets used for control groups. While chow diets are usually made of agricultural by-products, purified low-fat diets (LF) contain a higher percentage of easy metabolizable c...
Article
The activation of endoplasmic reticulum (ER) stress and a reduction of AMP-dependent protein kinase (AMPK) phosphorylation have been described in obesity. We hypothesize that a moderate caloric restriction (CR) might contribute to reducing ER stress and increasing AMPK phosphorylation in peripheral tissues from genetically obese Zucker fa/fa rats a...
Article
Background: Non-alcoholic fatty liver disease (NAFLD), a condition that leads to fibrosis, is caused by intake of very high-fat diets (HFDs). However, while the negative impact on the liver of these diets has been an issue of interest, systematic research on the effect of HFDs are lacking. Objective: To characterize the overall impact of HFDs on bo...
Article
Full-text available
Bariatric surgery (BS) results in sustained weight loss and may reverse inflammation, metabolic alterations, extracellular matrix remodeling and arterial stiffness. We hypothesize that increased stiffening in omental arteries from obese patients might be associated with an increase in MMP activity and a decrease in p-AMPK, together with systemic ox...
Article
Caloric restriction (CR)improves endothelial function through the upregulation of adenosine monophosphate-activated protein kinase (AMPK)and endothelial nitric oxide synthase (eNOS). Moreover, hydrogen peroxide (H 2 O 2 )is upregulated in yeast subjected to CR. Our aim was to assess if mild short-term CR increases vascular H 2 O 2 formation as a li...

Ectopic lipid deposition (ELD) is defined by excess fat storage in locations not classically associated with adipose tissue (AT) storage. ELD is positively correlated with insulin resistance and increased risk of metabolic disorders. ELD appears as lipid droplets or adipocytes, whose cell origin is unknown. We previously showed that subcutaneous AT...

Perivascular adipose tissue (PVAT) is cushion of fat tissue surrounding blood vessels, which is phenotypically different from other adipose tissue depots. PVAT is composed of adipocytes and stromal vascular fraction, constituted by different populations of immune cells, endothelial cells, and adipose-derived stromal cells. It expresses and releases...
Article
Full-text available
Perivascular adipose tissue (PVAT) releases numerous factors and adipokines with paracrine effects on both vascular structure and function. These effects are variable as they depend on regional differences in PVAT among blood vessels and vary with changes in adiposity. There is considerable evidence demonstrating an association between coronary PVA...

Article
Perivascular adipose tissue (PVAT) releases several important vasoactive factors with physiological and pathophysiological paracrine effects. A large body of evidence suggests regional phenotypic and functional differences among PVAT depots, depending on the specific vascular bed or different regions in the vascular bed where the PVAT is located. T...
Article
The aim of this study was to characterize alterations in vascular structure and mechanics in murine mesenteric arteries from obese non-hypertensive mice, as well as their relationship with adipokines. Four-week old C57BL/6J male mice were assigned either to a control (C, 10% kcal from fat) or a high-fat diet (HFD, 45% kcal from fat) for 32 weeks. H...
Article
Full-text available
The hypothesis of this study is that long-term high-fat diets (HFD) induce perivascular adipose tissue (PVAT) dysfunction characterized by a redox imbalance, which might contribute to aggravate endothelial dysfunction in obesity. C57BL/6J mice were fed either control or HFD (45% kcal from fat) for 32 weeks. Body weight, lumbar and mesenteric adipos...
Article
Background/objectives: Adipose tissue (AT) is a dynamic organ that expands and contracts rapidly. It is composed of adipocytes and of cell populations among which immune cells and mesenchymal progenitors known as adipose stromal cells (ASCs). The AT cell turnover has been extensively studied. Surprisingly it has only been viewed as the result of b...
Article
Full-text available
Dietary treatment with high-fat diets (HFD) triggers diabetes and hyperleptinemia, concomitantly with a partial state of leptin resistance that affects hepatic and adipose tissue but not the heart. In this context, characterized by widespread steatosis, cardiac lipid content remains unchanged. As previously reported, HFD-evoked hyperleptinemia coul...
Article
The Munich Wistar Frömter (MWF) rat develops progressive spontaneous albuminuria largely attributable to quantitative trait loci on rat chromosome (RNO)6 and RNO8, respectively. We tested the hypothesis whether quantitative trait loci on these chromosomes are linked to both albuminuria and endothelial dysfunction. Experiments were performed in male...
Article
Adipose tissue (AT) has become accepted as a source of multipotent progenitor cells, the adipose derived stroma/stem cells (ASCs). In this regard, considerable work has been performed to harvest and characterize this cell population as well as to investigate the mechanisms by which transplanted ASCs mediate tissue regeneration. In contrast the endo...
Article
Full-text available
Most blood vessels are surrounded by adipose tissue. Similarly to the adventitia, perivascular adipose tissue (PVAT) was considered only as a passive structural support for the vasculature, and it was routinely removed for isolated blood vessel studies. In 1991, Soltis and Cassis demonstrated for the first time that PVAT reduced contractions to nor...
Article
Full-text available
Leptin causes vasodilatation both by endothelium-dependent and -independent mechanisms. Leptin is synthesized by perivascular adipose tissue (PVAT). The hypothesis of this study is that a decrease of leptin production in PVAT of spontaneously hypertensive rats (SHR) might contribute to a diminished paracrine anticontractile effect of the hormone. W...
Article
Liver growth factor (LGF) is an albumin-bilirubin complex with antioxidant actions in vitro. In spontaneously hypertensive rats (SHRs), short LGF treatment exerts antihypertensive and antifibrotic effects. We aimed to determine if LGF treatment (4 i.p. injections, 4.5 μg/rat over 12 days) reduces oxidative stress in SHRs using Wistar-Kyoto (WKY) as...
Article
High-fat (HF) diets trigger an increase in adipose tissue and body weight (BW) and disordered eating behavior. Our study deals with the hypothesis that circadian distribution of energy intake is more relevant for BW dynamics than diet composition. Four-week-old mice were exposed for 8 wk to a HF diet and compared with animals receiving control chow...
Article
Leptin is an adipocyte-derived hormone which stimulates β-oxidation in peripheral tissues and prevents steatosis. Because leptin production naturally increases during adult life, we have hypothesized that leptin receptors might undergo a physiological and gradual desensitization during ageing. Therefore we have characterized in three- five- and ten...
Article
It has been suggested that hyperglycemia and insulin resistance triggered by energy-dense diets can account for hippocampal damage and deficits of cognitive behaviour. We wonder if the impairment of learning and memory processes detected in diet-induced obese (DIO) mice is linked to diet composition itself. With this purpose we have evaluated learn...
Article
Full-text available
Perivascular adipose tissue (PVAT) plays a paracrine role in regulating vascular tone. We hypothesize that PVAT undergoes adaptative mechanisms during initial steps of diet-induced obesity (DIO) which contribute to preserve vascular function. Four-week-old male C57BL/6J mice were assigned either to a control [low-fat (LF); 10% kcal from fat] or to...
Article
Full-text available
Acute leptin increase as well as endogenous hyperleptinemia evoked by high-fat diets (HF) activate fatty acid metabolism in nonadipose tissues. This supports the notion that hyperleptinemia is pivotal to prevent/delay steatosis during periods of positive energy balance. We have previously shown that long-term HF spares ectopic accumulation of lipid...
Chapter
The study of vascular tone regulation has been traditionally focused on layer-specific mechanisms and has changed through the years. Most early functional studies ­characterized vasoconstrictor and vasodilator agents and their receptor types and subtypes. At the same time, a bulk of investigation focused on the neural regulation of medial function,...
Article
In the last years a paracrine role for perivascular adipose tissue (PVAT) in the regulation of vascular function has been uncovered by several studies. Soltis and Cassis were the first to demonstrate that PVAT significantly attenuates vascular responsiveness of rat aortic rings to norepinephrine. More recent reports have confirmed the inhibitory ac...
