Obesity increases susceptibility to multiple organ disorders, however, underlying mechanisms remain unclear. The subclinical inflammation assisted by obesity-induced gut permeability may underlie obesity-associated co-morbidities. Despite eminent clinical significance of the obesity led barrier abnormalities, its precise molecular regulation remains It is also unknown whether deregulations, similar gut, characterize other vital organs in obese individuals. claudin family proteins integral tight junction (TJ), apical cell-cell adhesion and a key regulator epithelial barrier. Using comprehensive physiological biochemical analysis intestinal renal tissues from high-fat diet fed mice, critical for maintaining metabolic homeostasis, this study demonstrates that profound TJ-restructuring tissue-specific switching organs. Protein expression cellular distribution were examined. In-silico further highlighted potential association select claudins, modulated obesity, with signaling pathways pathological significance. In vitro studies using Leptin or DCA-treatment suggested causal changes tissue microenvironment regulating deregulations manner. Overall, current findings advances our understanding undertakings associated help predispose specific diseases identifies novel windows preventive and/or therapeutic interventions.

The occurrence of obesity has increased across the whole world. Many epidemiological studies have indicated that strongly contributes to development cancer, cardiovascular diseases, type 2 diabetes, liver diseases and other disorders, accounting for a heavy burden on public health-care systems every year. Excess energy uptake induces adipocyte hypertrophy, hyperplasia formation visceral fat in non-adipose tissues evoke disease, diseases. Adipose tissue can also secrete adipokines inflammatory cytokines affect local microenvironment, induce insulin resistance, hyperglycemia, activate associated signaling pathways. This further exacerbates progression obesity-associated Although some progress treatment been achieved preclinical clinical studies, pathogenesis obesity-induced are complex unclear. We still need understand their links better guide In this review, we review between with view improve future management its co-morbidities.

The negative effect of obesity on kidney health has been reported. association between weight-adjusted-waist index (WWI, a newly developed adiposity index) and albuminuria not reported earlier.This cross-sectional study was conducted among adults with complete data about WWI urinary albumin-to-creatinine ratio (ACR) in 2005-2018 National Health Nutrition Examination Survey (NHANES). calculated as waist circumference (WC) divided by the square root weight. Weighted multivariable logistic regression generalized additive model were employed to explore independent relationship its non-linearity. A two-piecewise linear used calculate threshold effect. Subgroup analysis interaction tests also performed.A total 36,921 participants enrolled prevalence 9.32%. increased higher tertiles (Tertile 1: 5.31%, Tertile 2: 8.23%, 3: 15.65%). positively associated likelihood (OR = 1.28, 95% CI: 1.15-1.43), this remains stable subgroups (all P for trend > 0.05).

Enhanced activation of the mineralocorticoid receptors (MRs) in cardiovascular tissues increases oxidative stress, maladaptive immune responses, and inflammation with associated functional vascular abnormalities. We previously demonstrated that consumption a Western diet (WD) for 16 weeks results aortic stiffening, these abnormalities were prevented by systemic MR blockade female mice. However, cell-specific role endothelial cell (ECMR) effects has not been explored.We hypothesized specific deletion ECMR would prevent WD-induced sodium channel activation, reductions bioavailable nitric oxide, increased remodeling, stiffness females.Four-week-old knockout wild-type mice fed either mouse chow or WD weeks. feeding resulted dysfunction as determined vivo pulse wave velocity ex atomic force microscopy, wire pressure myography. The was enhanced attenuated oxide synthase proinflammatory response fibrosis. Conversely, deficiency fibrosis conjunction stress macrophage polarization, restoration activation.Increased signaling plays key reduced production, lead to remodeling

Obesity is an emerging pandemic driven by consumption of a diet rich in fat and highly refined carbohydrates (a Western diet) sedentary lifestyle both children adults. There mounting evidence that arterial stiffness obesity independent strong predictor cardiovascular disease (CVD), cognitive functional decline, chronic kidney disease. Cardiovascular precursor to atherosclerosis, systolic hypertension, cardiac diastolic dysfunction, impairment coronary cerebral flow. Moreover, premenopausal women lose the CVD protection normally afforded them setting obesity, insulin resistance, diabetes, this loss inextricably linked increased propensity for stiffness. Stiffness endothelial vascular smooth muscle cells, extracellular matrix remodeling, perivascular adipose tissue inflammation, immune cell dysfunction contribute development obesity. Enhanced cortical decreases generation nitric oxide, oxidative stress promotes destruction oxide. Our research over past 5 years has underscored important role aldosterone mineralocorticoid receptor activation driving stiffness, especially females consuming diet. In review cellular mechanisms obesity-associated are highlighted.

The global burden of diabetes mellitus and its related complications are currently increasing. Diabetes affects the heart through various mechanisms including microvascular impairment, metabolic disturbance, subcellular component abnormalities, cardiac autonomic dysfunction, a maladaptive immune response. Eventually, can cause functional structural changes in myocardium without coronary artery disease, disorder known as diabetic cardiomyopathy (DCM). There many diagnostic tools management options for DCM, although it is difficult to detect development effectively prevent progression. In this review, we summarize current research regarding pathophysiology pathogenesis DCM. Moreover, discuss emerging evaluation methods treatment strategies which may help our understanding underlying facilitate identification possible new therapeutic targets.

Women are especially predisposed to development of arterial stiffening secondary obesity because consumption excessive calories. Enhanced activation vascular mineralocorticoid receptors impairs insulin signaling, induces oxidative stress, inflammation, and maladaptive immune responses. We tested whether a subpressor dose receptor antagonist, spironolactone (1 mg/kg per day) prevents aortic femoral artery in female C57BL/6J mice fed high-fat/high-sugar western diet (WD) for 4 months (ie, from 4-20 weeks age). Aortic stiffness were assessed using ultrasound, pressurized vessel preparations, atomic force microscopy. WD induced weight gain resistance compared with control diet-fed these abnormalities unaffected by spironolactone. Blood pressures heart rates normal or Spironolactone prevented WD-induced aorta artery, as well endothelial smooth muscle cells, within explants. impaired protein kinase B/endothelial nitric oxide synthase endothelium-dependent endothelium-independent vasodilation. ameliorated medial thickening fibrosis the associated progrowth extracellular 1/2 pathway. Finally, preservation WD-fed was attenuated systemic inflammation an anti-inflammatory shift cell marker genes. Low-dose may represent novel prevention strategy attenuate growth pathway signaling remodeling prevent WD.
