Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disorder in the world. We have seen that gluten intake exacerbated obesity and atherosclerosis in apolipoprotein E knockout (ApoE-/-) mice. In this study, we investigated the effect of gluten consumption on inflammation and oxidative stress in the liver of mice with NAFLD. Male ApoE-/- mice were fed a gluten-free (GF-HFD) or gluten-containing (G-HFD) high-fat diet for 10 weeks. Blood, liver, and spleen were collected to perform the analyses. The animals of the gluten group had increased hepatic steatosis, followed by increased serum AST and ALT. Gluten intake increased hepatic infiltration of neutrophils, macrophages, and eosinophils, as well as the levels of chemotaxis-related factors CCL2, , and . The production of the TNF, IL-1β, IFNγ, and IL-4 cytokines in the liver was also increased by gluten intake. Furthermore, gluten exacerbated the hepatic lipid peroxidation and nitrotyrosine deposition, which were associated with increased production of ROS and nitric oxide. These effects were related to increased expression of NADPH oxidase and iNOS, as well as decreased activity of superoxide dismutase and catalase enzymes. There was an increased hepatic expression of the NF-κB and AP1 transcription factors, corroborating the worsening effect of gluten on inflammation and oxidative stress. Finally, we found an increased frequency of CD4+FOXP3+ lymphocytes in the spleen and increased gene expression of Foxp3 in the livers of the G-HFD group. In conclusion, dietary gluten aggravates NAFLD, exacerbating hepatic inflammation and oxidative stress in obese ApoE-deficient mice.

Palmitoylethanolamide (PEA) is emerging as a promising therapeutic agent for neuropathic and other pain-related conditions. This naturally occurring fatty acid has drawn interest because of its ability to regulate pain and inflammation. Initially identified in food sources, PEA has been the subject of extensive research to elucidate its properties, efficacy, and clinical applications.

Topotactic transformation is an emerging strategy for synthesizing materials with exotic functional properties. In this report, instead of producing new crystals with related structures, we exploited the topotactic transformation phenomenon to spontaneously produce compositionally diverse nanostructures on the transforming substrate. The surface of magnetite nanoparticles (Fe3O4 NPs) is topotactically transformed into maghemite (γ-Fe2O3).

Zinc is essential for maintaining the integrity and repair of small intestinal epithelial cells while zinc deficiency could induce the inflammatory infiltration and imbalance of intestinal flora in the intestine. In this study, glycosylation between oyster protein hydrolysate (OPH) and chitosan oligosaccharide (COS) was conducted and used as the carrier of zinc ions (OCZn). The results of zeta potential and particle size distribution showed that the OPH-COS successfully bound to zinc ions to form OCZn with a surface zinc content of 0.

Hepatocellular carcinoma (HCC) is a widely prevalent type of primary liver cancer. However, strategies for pretumor intervention are still limited. In this study, a liver-specific Zbtb7b knockout mouse model was used to evaluate the role of Zbtb7b in metabolic dysfunction-associated steatotic liver disease (MASLD)-related HCC development.
