Ventricular arrhythmias are a common cause of sudden cardiac death, and their occurrence is higher in obese subjects. Abnormal gating of ryanodine receptors (RyR2), the calcium release channels of the sarcoplasmic reticulum, can produce ventricular arrhythmias. Since obesity promotes oxidative

Underlying mechanisms preserving coronary basal tone and NO-mediated relaxation in obesity: Involvement of β1 subunit-mediated upregulation of BKCa channels.

The impact of obesity on vasomotor regulation of coronary arteries and its underlying mechanisms are not completely understood and, in particular, the role of BKCa channels in the NO-mediated coronary vasodilation in obesity remains to be elucidated. The effects of selective blockade of BKCa channel

Pancreatic beta-cells from obese-hyperglycemic mice are characterized by excessive firing of cytoplasmic Ca2+ transients.

Pancreatic beta-cells from obese-hyperglycemic (ob/ob) mice are widely used for studying the mechanisms of insulin release, including its regulation by the cytoplasmic Ca2+ concentration ([Ca2+]i). In this study, we compared changes of [Ca2+]i in single beta-cells isolated from ob/ob mice with those

Cardiac function and intracellular Ca2+ handling proteins are not impaired by high-saturated-fat diet-induced obesity.

Obesity is often associated with changes in cardiac function; however, the mechanisms responsible for functional abnormalities have not yet been fully clarified. Considering the lack of information regarding high-saturated-fat diet-induced obesity, heart function, and the proteins involved in

High cortisol responses identify propensity for obesity that is linked to thermogenesis in skeletal muscle.

Subjects characterized as cortisol high responders (HRs) consume more calories after stress, but it is unknown whether cortisol responsiveness predicts a propensity for obesity. Female sheep with either high or low cortisol responses to adrenocorticotropin (ACTH) were identified. Body composition

Obesity induces upregulation of genes involved in myocardial Ca2+ handling.

Obesity is a complex multifactorial disorder that is often associated with cardiovascular diseases. Research on experimental models has suggested that cardiac dysfunction in obesity might be related to alterations in myocardial intracellular calcium (Ca2+) handling. However, information about the

Influence of long-term obesity on myocardial gene expression.

BACKGROUND Several authors have shown that deterioration of cardiac function is associated with the degree and duration of obesity. It is necessary to establish the gene expression patterns after prolonged periods of obesity. OBJECTIVE This study tested the hypothesis that increased duration of

Impaired Ca2+ handling in resistance arteries from genetically obese Zucker rats: Role of the PI3K, ERK1/2 and PKC signaling pathways.

The impact of obesity on vascular smooth muscle (VSM) Ca2+ handling and vasoconstriction, and its regulation by the phosphatidylinositol 3-kinase (PI3K), mitogen activated protein kinase (MAPK) and protein kinase C (PKC) were assessed in mesenteric arteries (MA) from obese Zucker rats (OZR).

Exercise training and caloric restriction prevent reduction in cardiac Ca2+-handling protein profile in obese rats.

Previous studies show that exercise training and caloric restriction improve cardiac function in obesity. However, the molecular mechanisms underlying this effect on cardiac function remain unknown. Thus, we studied the effect of exercise training and/or caloric restriction on cardiac function and

This study examined the hypothesis that the prediabetic metabolic syndrome alters expression, phosphorylation state and binding affinity of cardiac RyR2. Real-time PCR and Western blot analysis were used to assess mRNA and protein expression in the left ventricle, right ventricle and right atrium

Metabolic syndrome is characterized by a combination of obesity, hypertension, insulin resistance, dyslipidemia, and impaired glucose tolerance. This multifaceted syndrome is often accompanied by a hyperdynamic circulatory state characterized by increased blood pressure, total blood volume, cardiac

Obesity is a major public health problem worldwide. In the United States, one-third of women of reproductive age are obese. Human studies show that maternal obesity (MO) predisposes offspring to cardiovascular disease. However, the underlying mechanisms remain unclear. Given the similarities between
