Emerging research suggests that bone homeostasis can also be influenced by the gut microbiota. The aim of this study was to assess possible alterations in gut microbiota in an experimental obesity model induced by a high-fat diet (HFD) and the possible effects on parameters of bone metabolism and remodeling. Male Wistar rats were fed a HFD (60% lipids) or standard (control) diet for 14 weeks. Biochemical and hormonal parameters, bone histomorphometry, bone protein levels, and gut microbiota composition were analyzed. HFD animals exhibited a greater gut microbiota α-diversity represented by the Shannon Index and an increased relative abundance of the Proteobacteria phylum. Histomorphometry detected lower bone formation in the HFD group, accompanied by increased levels of serum and bone leptin and FGF-23 (fibroblast growth factor-23). The Shannon Index was correlated directly with bone FGF-23 (R 0.96, p = 0.04) and inversely with the osteoblastic surface (R -0.95, p = 0.04). The present study disclosed a significant increase in gut microbiota α-diversity and relative abundance of Proteobacteria phylum in obese animals fed a high-fat diet in parallel with increased levels of bone and serum leptin and FGF-23 and lower bone formation. The associations of Shannon Index with bone levels of FGF-23 and reduced osteoblastic surface suggest a link between HFD-induced higher gut microbiota diversity and low bone formation.</p>","PeriodicalId":18086,"journal":{"name":"Lipids","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143657654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LFBE significantly inhibited lipid accumulation by decreasing the expression of adipogenesis-related transcription factors, including peroxisome proliferator-activated receptor (PPAR-γ) and CCAAT/enhancer binding protein (C/EBP-α) in differentiated 3 T3-L1 cells. The expression levels of adiponectin, acetyl CoA carboxylase (ACC), and fatty acid synthase (FAS) were also suppressed in differentiated three T3-L1 cells. Administration of LFBE significantly reduced insulin resistance, blood lipid profiles, and improved metabolic hormones in HFD-induced obese rats. Furthermore, the serum pro-inflammatory cytokines including CRP, IL-6, TNFα, and INFγ in HFD-induced obese rats were significantly decreased after LFBE administration. LFBE treatment also attenuated oxidative stress in HFD-induced obese rats by decreasing MDA production and restoring SOD and catalase enzymatic activity. Administration of LFBE could modulate gut microbiota imbalance by increasing the abundance of Lactobacillus and Ruminococcaceae UCG-014 and decreasing Prevotella-9 at the genus level and restoring intestinal barrier dysfunction in HFD-induced obesity rats.

Both docosahexaenoic acid (DHA) and medium chain triglycerides (MCTs) play essential roles in lipid metabolism and the inhibition of amyloid-β (Aβ) accumulation. We aimed to explore the possible association between cerebral Aβ deposition and the development of NAFLD and to investigate the effect of DHA combined with MCTs on delaying NAFLD progression and Aβ accumulation. To this end, 40 three-month-old APP/PS1 male mice were randomly assigned to 4 groups. The mice were fed a control diet, a DHA (2.91 g/kg) diet, an MCTs (100 g/kg) diet, or a DHA + MCTs diet for 8 months. Ten C57BL/6J mice were fed a control diet and used as the wild-type (WT) group. The results indicated that APP/PS1 mice exhibited NAFLD and cerebral Aβ accumulation. DHA combined with MCTs decreased blood and liver lipids, relieved hepatic steatosis and fat accumulation, and decreased the level of Aβ in the brain and serum. Moreover, DHA combined with MCTs significantly upregulated the levels of Aβ clearance-related proteins in the liver, modulated the expression of key hepatic lipid metabolism enzymes and upstream hepatic lipid metabolism factors. In conclusion, compared with wild-type mice, APP/PS1 mice may be more sensitive to changes in lipid metabolism due to the accumulation of Aβ. DHA combined with MCTs alleviated NAFLD and decreased brain and serum Aβ levels in APP/PS1 mice compared with the control group.

Here, we demonstrate the first use of a miniaturized IV method that requires only milliliter quantities of hazardous chemicals and sample sizes such that it is feasible to assay biological membranes. Briefly, lipids are exposed to iodine monochloride, resulting in the replacement of unsaturated bonds with di-halogenated single bonds. Potassium iodide then reacts with unreacted iodine monochloride forming I<sub>2</sub>, which is quantified through titration with sodium thiosulfate. To demonstrate the biological relevance of our assay, membrane lipids of Escherichia coli grown at 30, 37, and 42°C were analyzed, with IV increasing as temperature decreased, as would be expected. Importantly, multiple samples could be rapidly and simultaneously analyzed in a reproducible assay that did not require sophisticated equipment or data analysis methods.
