eNeuro 2021 Jul 29. Epub 2021 Jul 29.

Diabetes, Endocrinology, and Obesity Branch, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Bethesda, MD 20892, USA

Bombesin receptor subtype-3 (BRS3) is an orphan receptor that regulates energy homeostasis. We compared driver mice with constitutive or inducible Cre recombinase activity. The constitutive BRS3-Cre mice show reporter signal (Cre-dependent tdTomato) in the adult brain due to lineage tracing in the dentate gyrus, striatal patches, and indusium griseum, in addition to sites previously identified in the inducible BRS3-Cre mice (including hypothalamic and amygdala subregions, and parabrachial nucleus).

Fatty Acid Esters of Hydroxy Fatty Acids (FAHFAs) Are Associated With Diet, BMI, and Age.

Front Nutr 2021 12;8:691401. Epub 2021 Jul 12.

Else Kröner-Fresenius-Center of Nutritional Medicine, TUM School of Life Sciences, Technical University of Munich, Freising, Germany.

Fatty acid esters of hydroxy fatty acids (FAHFAs) are a group of fatty acids with potential anti-inflammatory and anti-diabetic effects. The blood levels of FAHFAs and their regulation in humans have hardly been studied. We aimed to investigate serum FAHFA levels in well-characterized human cohorts, to evaluate associations with age, sex, BMI, weight loss, diabetic status, and diet. Read More

Predicting the environmental suitability for onchocerciasis in Africa as an aid to elimination planning.

PLoS Negl Trop Dis 2021 Jul 28;15(7):e0008824. Epub 2021 Jul 28.

Department of Health Policy Planning and Management, University of Health and Allied Sciences, Ho, Ghana.

Recent evidence suggests that, in some foci, elimination of onchocerciasis from Africa may be feasible with mass drug administration (MDA) of ivermectin. To achieve continental elimination of transmission, mapping surveys will need to be conducted across all implementation units (IUs) for which endemicity status is currently unknown. Using boosted regression tree models with optimised hyperparameter selection, we estimated environmental suitability for onchocerciasis at the 5 × 5-km resolution across Africa. Read More

The glycosyltransferase ST3GAL2 modulates virus proliferation and the inflammation response in porcine reproductive and respiratory syndrome virus infection.

Arch Virol 2021 Jul 28. Epub 2021 Jul 28.

School of Life Sciences, Tianjin University, No. 92, Weijin Road, Nankai District, Tianjin, 300072, China.

β-galactoside α-2,3-sialyltransferase 2 (ST3GAL2) is a member of the sialyltransferase family that mediates terminal modification of glycoproteins and glycolipids. ST3GAL2 has been found to play a role in obesity, aging, and malignant diseases. In this study, we cloned porcine ST3GAL2 (pST3GAL2) from porcine alveolar macrophages (PAMs), and its role in porcine reproductive and respiratory syndrome virus (PRRSV) infection was investigated by transcriptome analysis.

Higher levels of anti-phosphorylcholine autoantibodies in early rheumatoid arthritis indicate lower risk of incident cardiovascular events.

Arthritis Res Ther 2021 Jul 27;23(1):201. Epub 2021 Jul 27.

Division of Gastroenterology and Rheumatology, Department of Medicine Huddinge, Karolinska Institutet, 171 77, Stockholm, Sweden.

Background: The increased risk of cardiovascular events (CVE) in rheumatoid arthritis (RA) is not fully explained by traditional risk factors. Immuno-inflammatory mechanisms and autoantibodies could be involved in the pathogenesis of atherosclerotic disease. It has been suggested that anti-phosphorylcholine antibodies (anti-PC) of the IgM subclass may have atheroprotective effects. Read More

Crown-like structures in breast adipose tissue of breast cancer patients: associations with CD68 expression, obesity, metabolic factors and prognosis.

NPJ Breast Cancer 2021 Jul 22;7(1):97. Epub 2021 Jul 22.

Department of Medicine, University of Toronto, Toronto, ON, Canada.

Crown-like structures of the breast (CLS-B), defined by the clustering of macrophages (identified using CD68 immunohistochemical staining) to surround a dying adipocyte, are a sign of adipose-tissue inflammation. In human cohorts, CLS-B positively correlates with older age, obesity, dyslipidemia and higher levels of glucose, insulin, C-reactive protein and IL-6. In an existing cohort of early-stage breast cancer patients, CLS-B were identified using H&E stained histologic sections (hCLS-B), and by CD68 immunohistochemistry (CD68 + CLS-B). Read More

Pak J Med Sci 2021 Jul-Aug;37(4):1161-1165

Prof. Dr. Bulent Ciftci, Yozgat Bozok University, Medical School, Department of Chest Diseases, Yozgat Turkey.

Background And Objectives: It is known that the prevalence of obstructive sleep apnea (OSA) is increased in acromegaly. Craniofacial anomalies, macroglossia, and thickening of the laryngeal wall caused by the increase in soft tissue in these patients lead to OSA. Also, the increase in growth hormone can trigger central apnea by causing a decrease in respiratory drive. Read More

Does intervention with GLP-1 receptor agonist semaglutide modulate perception of sweet taste in women with obesity: study protocol of a randomized, single-blinded, placebo-controlled clinical trial.

Trials 2021 Jul 19;22(1):464. Epub 2021 Jul 19.

Department of Endocrinology, Diabetes and Metabolic Diseases, Division of Internal Medicine, University Medical Centre Ljubljana, Zaloška cesta 7, SI-1000, Ljubljana, Slovenia.

Background: Preclinical studies demonstrated that glucagon-like peptide 1 (GLP-1) is locally synthesized in taste bud cells and that GLP-1 receptor exists on the gustatory nerves in close proximity to GLP-1-containing taste bud cells. This local paracrine GLP-1 signalling seems to be specifically involved in the perception of sweets. However, the role of GLP-1 in taste perception remains largely unaddressed in clinical studies.

STE20-Type Protein Kinase MST4 Controls NAFLD Progression by Regulating Lipid Droplet Dynamics and Metabolic Stress in Hepatocytes.

Hepatol Commun 2021 Jul 16;5(7):1183-1200. Epub 2021 Mar 16.

Department of Chemistry and Molecular Biology University of Gothenburg and Sahlgrenska University Hospital Gothenburg Sweden.

Nonalcoholic fatty liver disease (NAFLD) has emerged as a leading cause of chronic liver disease worldwide, primarily because of the massive global increase in obesity. Despite intense research efforts in this field, the factors that govern the initiation and subsequent progression of NAFLD are poorly understood, which hampers the development of diagnostic tools and effective therapies in this area of high unmet medical need. Here we describe a regulator in molecular pathogenesis of NAFLD: STE20-type protein kinase MST4. Read More

Mouse Spexin: (I) NMR Solution Structure, Docking Models for Receptor Binding, and Histological Expression at Tissue Level.

Front Endocrinol (Lausanne) 2021 2;12:681646. Epub 2021 Jul 2.

School of Biological Sciences, The University of Hong Kong, Hong Kong, Hong Kong.

Spexin (SPX), a highly conserved neuropeptide, is known to have diverse functions and has been implicated/associated with pathological conditions, including obesity, diabetes, anorexia nervosa, and anxiety/mood disorders. Although most of the studies on SPX involved the mouse model, the solution structure of mouse SPX, structural aspects for SPX binding with its receptors GalR2/3, and its cellular expression/distribution in mouse tissues are largely unknown. Using CD and NMR spectroscopies, the solution structure of mouse SPX was shown to be in the form of a helical peptide with a random coil from Asn to Pro in the N-terminal followed by an α-helix from Gln to Gln in the C-terminus.
