Geniposide Combined With Notoginsenoside R1 Attenuates Inflammation and Apoptosis in Atherosclerosis the AMPK/mTOR/Nrf2 Signaling Pathway.

Front Pharmacol 2021 7;12:687394. Epub 2021 Jul 7.

School of Traditional Chinese Medicine, Southern Medical University, Guangzhou, China.

Inflammation and apoptosis of vascular endothelial cells play a key role in the occurrence and development of atherosclerosis (AS), and the AMPK/mTOR/Nrf2 signaling pathway plays an important role in alleviating the symptoms of AS. Geniposide combined with notoginsenoside R1 (GN combination) is a patented supplement for the prevention and treatment of AS. It has been proven to improve blood lipid levels and inhibit the formation of AS plaques; however, it is still unclear whether GN combination can inhibit inflammation and apoptosis in AS by regulating the AMPK/mTOR/Nrf2 signaling pathway and its downstream signals.

Phenethylamine in chlorella alleviates high-fat diet-induced mouse liver damage by regulating generation of methylglyoxal.

NPJ Sci Food 2021 Jul 23;5(1):22. Epub 2021 Jul 23.

Division of Applied Biosciences, Graduate School of Agriculture, Kyoto University, Kitashirakawa Oiwake-cho, Kyoto, Japan.

This study examined the effects of oral administration of water extract of chlorella (WEC) (100 mg/kg bodyweight) and phenethylamine (10 μg/kg bodyweight) on high-fat diet (HFD)-induced liver damage in mice. Phenethylamine significantly mitigated HFD-induced lipid oxidation (generation of malondialdehyde) and liver damage without markedly decreasing hepatic lipid accumulation.

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.

Necrostatin-1 reduces cardiac and mitochondrial dysfunction in prediabetic rats.

J Endocrinol 2021 Jul 1. Epub 2021 Jul 1.

N Chattipakorn, Cardiac Electrophysiology Research and Training Center, Chiang Mai university, Chiang Mai, 50200, Thailand.

High fat diet (HFD) consumption induces prediabetes and left ventricular dysfunction through many pathways including the cell death pathway, necroptosis. Although benefits of necroptosis inhibitor (necrostatin-1 or Nec-1) in the brain of prediabetic rats have been shown, the effects of Nec-1 on cardiac autonomic function, blood pressure, and cardiac function, and the mechanisms involved have not been investigated. Male Wistar rats were fed with either a normal diet (n=8) or HFD (n=24) for 12 weeks to induce prediabetes. Read More

Biochim Biophys Acta Mol Cell Biol Lipids 2021 Jul 7;1866(10):159004. Epub 2021 Jul 7.

Department of Nutrition and Food Hygiene, School of Public Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China; Ministry of Education Key Laboratory of Environment, School of Public Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China. Electronic address:

The atherosclerosis "iron hypothesis" generates a fair amount of debate since it has been proposed. Here, we revisited the "iron hypothesis" by examining whether dietary iron overload would intensify iron deposition in plaques and thus lead to further exacerbation of atherosclerosis in apolipoprotein E knockout (ApoE KO) mice. ApoE KO mice were fed either a normal chow diet (ND) or a high fat diet (HFD) supplemented with or without 2% carbonyl iron (Fe) for 16 weeks. Read More

A high-fat diet exacerbates the Alzheimer's disease pathology in the hippocampus of the App knock-in mouse model.

Aging Cell 2021 Jul 10:e13429. Epub 2021 Jul 10.

Division of Neurofunctional Genomics, Department of Immunobiology and Neuroscience, Medical Institute of Bioregulation, Kyushu University, Fukuoka, Japan.

Insulin resistance and diabetes mellitus are major risk factors for Alzheimer's disease (AD), and studies with transgenic mouse models of AD have provided supportive evidence with some controversies. To overcome potential artifacts derived from transgenes, we used a knock-in mouse model, App , which accumulates Aβ plaques from 6 months of age and shows mild cognitive impairment at 18 months of age, without the overproduction of APP. In the present study, 6-month-old male App and wild-type mice were fed a regular or high-fat diet (HFD) for 12 months. Read More

Glycoursodeoxycholic acid ameliorates diet-induced metabolic disorders with inhibiting endoplasmic reticulum stress.

Clin Sci (Lond) 2021 Jul;135(14):1689-1706

Department of Cardiovascular Medicine, The First Affiliated Hospital of Xi'an Jiaotong University, Xi'an, Shaanxi, China.

Recent studies reveal that bile acid metabolite composition and its metabolism are changed in metabolic disorders, such as obesity, type 2 diabetes and metabolic associated fatty liver disease (MAFLD), yet its role and the mechanism remain largely unknown. In the present study, metabolomic analysis of 163 serum and stool samples of our metabolic disease cohort was performed, and we identified glycoursodeoxycholic acid (GUDCA), glycine-conjugated bile acid produced from intestinal bacteria, was decreased in both serum and stool samples from patients with hyperglycemia. RNA-sequencing and quantitative PCR results indicated that GUDCA alleviated endoplasmic reticulum (ER) stress in livers of high fat diet (HFD)-fed mice without alteration of liver metabolism.

Anal Chem 2021 Jul 6;93(28):9904-9911. Epub 2021 Jul 6.

Department of Chemistry, Wuhan University, Wuhan 430072, P. R. China.

Epoxy/dihydroxy-oxylipins are important biologically active compounds that are mainly formed from polyunsaturated fatty acids (PUFAs) in the reactions catalyzed by the cytochrome P450 (CYP 450) enzyme. The analysis of epoxy/dihydroxy-oxylipins would be helpful to gain insights into their landscape in living organisms and provide a reference for the biological studies of these compounds.
