Exercise-Training Regulates Apolipoprotein B in to Improve HFD-Mediated Cardiac Function Damage and Low Exercise Capacity.

Front Physiol 2021 7;12:650959. Epub 2021 Jul 7.

Key Laboratory of Physical Fitness and Exercise Rehabilitation of Hunan Province, Hunan Normal University, Changsha, China.

Apolipoprotein B plays an essential role in systemic lipid metabolism, and it is closely related to cardiovascular diseases. Exercise-training can regulate systemic lipid metabolism, improve heart function, and improve exercise capacity, but the molecular mechanisms involved are poorly understood. We used a model to demonstrate that exercise-training regulates the expression of (a homolog of apolipoprotein B) in cardiomyocytes, thereby resisting heart insufficiency and low exercise capacity caused by obesity.

Department of Endocrinology, The First Affiliated Hospital of Chongqing Medical University, Chongqing, China.

The clinical controversy of rosiglitazone as a hypoglycemic agent is potentially associated with heart failure, mainly due to its potent activation of peroxisome proliferator-activated receptor γ (PPARγ). PPARγ partial agonists showed superior pharmacological profiles to rosiglitazone. This study compared differences in cardiac morphology and function of the PPARγ partial agonist CMHX008 with rosiglitazone. Read More

Metabolic and Molecular Subacute Effects of a Single Moderate-Intensity Exercise Bout, Performed in the Fasted State, in Obese Male Rats.

Int J Environ Res Public Health 2021 Jul 15;18(14). Epub 2021 Jul 15.

Department of Physiology, Universidade Federal do Rio Grande do Sul (UFRGS), Porto Alegre 90050-170, RS, Brazil.

: Obesity represents a major global public health problem. Its etiology is multifactorial and includes poor dietary habits, such as hypercaloric and hyperlipidic diets (HFDs), physical inactivity, and genetic factors. Regular exercise is, per se, a tool for the treatment and prevention of obesity, and recent studies suggest that the beneficial effects of exercise can be potentiated by the fasting state, thus potentially promoting additional effects.

Necroptosis is required for atrial fibrillation and involved in aerobic exercise-conferred cardioprotection.

J Cell Mol Med 2021 Jul 20. Epub 2021 Jul 20.

Department of Cardiology, The Second Affiliate Hospital of Xi'an Jiaotong University, Xi'an, Shaanxi, China.

Necroptosis, a novel programmed cell death, plays a critical role in the development of fibrosis, yet its role in atrial fibrillation (AF) remains elusive. Mounting evidence demonstrates that aerobic exercise improves AF-related symptoms and quality of life. Therefore, we explored the role of necroptosis in AF pathogenesis and exercise-conferred cardioprotection. Read More

Biomed Res Int 2021 14;2021:6621027. Epub 2021 Jun 14.

Department of Dermatology, Hallym University Kangnam Sacred Heart Hospital, Hallym University College of Medicine, Seoul 07441, Republic of Korea.

Obesity can induce chronic low-grade inflammation via oxidative stress. Tetrahydrocurcumin (THC) is a major curcumin metabolite with anti-inflammatory and antioxidant effects, but little is known about its effects on the skin of obese individuals. Thus, the aim of this study was to investigate the effects of THC on inflammatory cytokine production, oxidative stress, and autophagy in the skin of mice with high-fat diet- (HFD-) induced obesity.

The Treatment of Rhodiola Mimics Exercise to Resist High-Fat Diet-Induced Muscle Dysfunction via Sirtuin1-Dependent Mechanisms.

Front Pharmacol 2021 15;12:646489. Epub 2021 Apr 15.

Division of Cardiac Rehabilitation, Department of Physical Medicine and Rehabilitation, Xiangya Hospital of Central South University, Changsha, China.

Muscle dysfunction is a complication of high-fat diet (HFD)-induced obesity that could be prevented by exercise, but patients did not get enough therapeutic efficacy from exercise due to multiple reasons. To explore alternative or supplementary approaches to prevent or treat muscle dysfunction in individuals with obesity, we investigated the effects of Rhodiola on muscle dysfunction as exercise pills. SIRT1 might suppress atrogenes expression and improve mitochondrial quality control, which could be a therapeutic target stimulated by exercise and Rhodiola, but further mechanisms remain unclear.

Endothelial epidermal growth factor receptor is of minor importance for vascular and renal function and obesity-induced dysfunction in mice.

Sci Rep 2021 Mar 31;11(1):7269. Epub 2021 Mar 31.

Julius-Bernstein-Institute of Physiology, Martin Luther University Halle-Wittenberg, Magdeburger Strasse 6, 06112, Halle (Saale), Germany.

Vascular EGF receptors (EGFR) influence function and structure of arterial vessels. In genetic mouse models we described the role of vascular smooth muscle (VSMC) EGFR for proper physiological function and structure as well as for pathophysiological alterations by obesity or angiotensin II. As the importance of endothelial (EC) EGFR in vivo is unknown, we analyzed the impact of EC-EGFR knockout in a conditional mouse model on vascular and renal function under control condition as well as in obesity and in comparison to VSMC-KO.

Reciprocal control of obesity and anxiety-depressive disorder via a GABA and serotonin neural circuit.

Mol Psychiatry 2021 Mar 26. Epub 2021 Mar 26.

USDA/ARS Children's Nutrition Research Center, Department of Pediatrics, Baylor College of Medicine, Houston, TX, USA.

The high comorbidity between obesity and mental disorders, such as depression and anxiety, often exacerbates metabolic and neurological symptoms significantly. However, neural mechanisms that underlie reciprocal control of feeding and mental states are largely elusive. Here we report that melanocortin 4 receptor (MC4R) neurons located in the dorsal bed nucleus of the stria terminus (dBNST) engage in the regulation of mentally associated weight gain by receiving GABAergic projections from hypothalamic AgRP neurons onto α5-containing GABA receptors and serotonergic afferents onto 5-HT receptors.

Oxid Med Cell Longev 2021 19;2021:8875729. Epub 2021 Feb 19.

Division of Nephrology and Hypertension, Mayo Clinic, Rochester, Minnesota, USA.

Global consumption of high-fat diets (HFD) is associated with an increased incidence of cardiometabolic syndrome and cardiac injury, warranting identification of cardioprotective strategies. Cardioprotective effects of quercetin (Q) have mostly been evaluated in ischemic heart disease models and attributed to senolysis. We hypothesized that Q could alleviate murine cardiac damage caused by HFD by restoring the myocardial microcirculation. Read More

Deletion of intestinal epithelial AMP-activated protein kinase alters distal colon permeability but not glucose homeostasis.

Mol Metab 2021 May 4;47:101183. Epub 2021 Feb 4.

Université de Paris, Institut Cochin, INSERM, CNRS, F-75014 Paris, France. Electronic address:

Objective: The intestinal epithelial barrier (IEB) restricts the passage of microbes and potentially harmful substances from the lumen through the paracellular space, and rupture of its integrity is associated with a variety of gastrointestinal disorders and extra-digestive diseases. Increased IEB permeability has been linked to disruption of metabolic homeostasis leading to obesity and type 2 diabetes. Interestingly, recent studies have uncovered compelling evidence that the AMP-activated protein kinase (AMPK) signaling pathway plays an important role in maintaining epithelial cell barrier function.

J Am Heart Assoc 2020 11 19;9(21):e016929. Epub 2020 Oct 19.

Jagiellonian Centre for Experimental Therapeutics (JCET) Jagiellonian University Krakow Poland.

Background Long-term feeding with a high-fat diet (HFD) induces endothelial dysfunction in mice, but early HFD-induced effects on endothelium have not been well characterized. Methods and Results Using an magnetic resonance imaging-based methodology that allows characterization of endothelial function in vivo, we demonstrated that short-term (2 weeks) feeding with a HFD to mice or to mice resulted in the impairment of acetylcholine-induced response in the abdominal aorta (AA), whereas, in the thoracic aorta (TA), the acetylcholine-induced response was largely preserved. Similarly, HFD resulted in arterial stiffness in the AA, but not in the TA. Read More
