Apoptosis 2021 May 12. Epub 2021 May 12.

Instituto de Estudios Inmunológicos y Fisiopatológicos-IIFP, Facultad de Ciencias Exactas, Universidad Nacional de La Plata, Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET), La Plata, Argentina.

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is characterized by chronic, relapsing intestinal inflammation. Galectin-1 (Gal-1) is an endogenous lectin with key pro-resolving roles, including induction of T-cell apoptosis and secretion of immunosuppressive cytokines. Despite considerable progress, the relevance of Gal-1-induced T-cell death in inflamed tissue from human IBD patients has not been ascertained. Read More

Comprehensive analysis for detecting radiation-specific molecules expressed during radiation-induced rat thyroid carcinogenesis.

J Radiat Res 2021 May;62(Supplement_1):i78-i87

Department of Tumor and Diagnostic Pathology, Atomic Bomb Disease Institute, Nagasaki University Graduate School of Biomedical Sciences, Nagasaki, Japan.

Although the association between radiation exposure and thyroid carcinogenesis is epidemiologically evident, 'true' radiation-induced cancers cannot be identified from biological evidence of radiation-associated cases. To assess the individual risk for thyroid cancer due to radiation exposure, we aimed to identify biomarkers that are specifically altered during thyroid carcinogenesis after irradiation in a time-dependent manner in an animal model. Thyroid glands were obtained from rats (n = 175) at 6-16 months after local X-ray (0. Read More

Effect of D-allulose feeding on the hepatic metabolomics profile in male Wistar rats.

Food Funct 2021 May;12(9):3931-3938

Research and Development, Matsutani Chemical Industry Co., Ltd, 5-3 Kita-Itami, Itami City, Hyogo 664-8508, Japan.

The rare sugar d-allulose is a C-3 epimer of d-fructose and is known to have several health benefits such as anti-obesity and anti-diabetic effects through the alteration of enzymatic and genetic expressions in each organ. Most of the ingested d-allulose is absorbed in the small intestine and then rapidly excreted in the urine. As d-allulose was reported to be present in the liver before it is excreted, d-allulose may modulate some hepatic metabolites including glucose and lipid metabolism. Read More

DNA methylation is involved in acclimation to iron deficiency in rice (Oryza sativa).

Plant J 2021 May 12. Epub 2021 May 12.

State Key Laboratory of Plant Physiology and Biochemistry, College of Life Sciences, Zhejiang University, Hangzhou, Zhejiang, 310058, P. R. China.

Iron (Fe) is an essential micronutrient in plants and Fe limitation significantly affects plant growth, yield and food quality. While many studies have reported the transcriptomic profile and pursue molecular mechanism in response to Fe limitation, little is known if epigenetic factors play a role in response to Fe deficiency. In this study, whole-genome bisulfite sequencing analysis, high throughput RNA-seq of mRNA, small RNA and transposable element (TE) expression with root and shoot organs of rice seedlings under Fe-sufficient and Fe-deficient conditions were performed.

Oxid Med Cell Longev 2021 21;2021:5543025. Epub 2021 Apr 21.

VINČA Institute of Nuclear Sciences, National Institute of the Republic of Serbia, Laboratory for Radiobiology and Molecular Genetics, University of Belgrade, Belgrade, Serbia.

The benefits of walnut () consumption for metabolic health are known, but the molecular background underlying their putative antioxidant and anti-inflammatory/immunomodulatory effects is underexplored. We assessed that walnut supplementation (6 weeks) reverted unfavorable changes of the SIRT1/FoxO3a/MnSOD/catalase axis in the heart induced by fructose-rich diet (FRD). Intriguingly, Nox4 was increased by both FRD and walnut supplementation. Read More

A SARS-CoV-2 antibody curbs viral nucleocapsid protein-induced complement hyperactivation.

Nat Commun 2021 May 11;12(1):2697. Epub 2021 May 11.

Molecular Imaging Center, Guangdong Provincial Key Laboratory of Biomedical Imaging, The Fifth Affiliated Hospital, Sun Yat-sen University, Zhuhai, China.

Although human antibodies elicited by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid (N) protein are profoundly boosted upon infection, little is known about the function of N-reactive antibodies. Herein, we isolate and profile a panel of 32 N protein-specific monoclonal antibodies (mAbs) from a quick recovery coronavirus disease-19 (COVID-19) convalescent patient who has dominant antibody responses to the SARS-CoV-2 N protein rather than to the SARS-CoV-2 spike (S) protein. The complex structure of the N protein RNA binding domain with the highest binding affinity mAb (nCoV396) reveals changes in the epitopes and antigen's allosteric regulation. Read More

mSystems 2021 May 11;6(3). Epub 2021 May 11.

Department of Neuroscience, The Ohio State University College of Medicine, Columbus, Ohio, USA

Emerging data indicate that gut dysbiosis contributes to many human diseases, including several comorbidities that develop after traumatic spinal cord injury (SCI). To date, all analyses of SCI-induced gut dysbiosis have used 16S rRNA amplicon sequencing. This technique has several limitations, including being susceptible to taxonomic "blind spots," primer bias, and an inability to profile microbiota functions or identify viruses. Read More

J Gastrointest Cancer 2021 May 11. Epub 2021 May 11.

Department of Botany and Microbiology, Faculty of Science, Al-Azhar Uniersity, 11847, Nasr City, Cairo, Egypt.

The present work aimed to study the activity of naturally derived fungal secondary metabolites as anticancer agents concerning their cytotoxicity, apoptotic, genetic, and histopathological profile. It was noticed that Aspergillus terreus, Aspergillus flavus, and Aspergillus fumigatus induced variable toxic potential that was cell type, secondary metabolite type, and concentration dependent. Human colonic adenocarcinoma cells (Caco-2) showed less sensitivity than hepatocyte-derived cellular carcinoma cells (HuH-7), and in turn, the half-maximal inhibitory concentration (IC) was variable.

Environ Pollut 2021 May 4;286:117294. Epub 2021 May 4.

Key Laboratory of Environmental Remediation and Ecological Health, Ministry of Education, College of Environmental and Resource Sciences, Zhejiang University, Hangzhou, 310058, China. Electronic address:

Benzophenone-type UV filters have been implicated in multiple adverse reproductive outcomes, yet the underlying processes and molecular targets on the female reproductive tract remain largely unknown. Herein, we investigated the effect of dioxybenzone, one of the widely used congeners, and its demethylated (M1) and hydroxylated (M2) metabolites on transcriptome profiles of ICR mice uterus and identified potential cellular targets in human endometrial stromal cells (HESCs) separated from normal endometrium tissues. Dioxybenzone, M1 and M2 (20 mg/kg bw/d) significantly induced transcriptome aberration with the induction of 683, 802, and 878 differentially expressed genes mainly involved in cancer, reproductive system disease and inflammatory disease.

Arch Pharm (Weinheim) 2021 May 9:e2000469. Epub 2021 May 9.

Department of Pharmacology, Faculty of Pharmacy, Yeditepe University, Istanbul, Turkey.

To obtain new anti-inflammatory agents, recent studies have aimed to replace the carboxylate functionality of nonsteroidal anti-inflammatory drugs with less acidic heterocyclic bioisosteres like 1,3,4-oxadiazole to protect the gastric mucosa from free carboxylate moieties. In view of these observations, we designed and synthesized a series of 3,5-disubstituted-1,3,4-oxadiazole derivatives as inhibitors of prostaglandin E (PGE ) and NO production with an improved activity profile. As initial screening, and to examine the anti-inflammatory activities of the compounds, the inhibitions of the productions of lipopolysaccharide-induced NO and PGE in RAW 264. Read More

Methylglyoxal Drives a Distinct, Nonclassical Macrophage Activation Status.

Thromb Haemost 2021 May 9. Epub 2021 May 9.

Institute for Diabetes and Cancer, Helmholtz Center Munich, German Research Center for Environmental Health, Neuherberg, Germany.

Metabolic complications in diabetic patients are driven by a combination of increased levels of nutrients and the presence of a proinflammatory environment. Methylglyoxal (MG) is a toxic byproduct of catabolism and has been strongly associated with the development of such complications. Macrophages are key mediators of inflammatory processes and their contribution to the development of metabolic complications has been demonstrated. Read More
