Ergosterol, a natural sterol abundant in edible fungi, has shown pharmacological effects that may benefit DKD treatment. However, its precise mechanisms of action remain elusive. This study aimed to evaluate the therapeutic efficacy of ergosterol in DKD and to delineate the underlying mechanisms. <i>Methods</i>: Transcriptome microarray sequencing data from DKD patients retrieved from the public GEO database, as well as data from mouse DKD models, were analyzed to identify differentially expressed genes. Db/db mouse, high-glucose-induced HK-2 cells and conditioned THP-1 cells were employed to evaluate the impact of ergosterol on renal function, lipid metabolism, and macrophage phenotypic transformation. <i>Results</i>: Transcriptional profiling of DKD kidneys revealed alterations in fatty acid metabolism, which were corroborated in db/db mice. Ergosterol significantly improved renal function, reduced lipid accumulation, and mitigated inflammation. CPT1A, a key modulator of fatty acid metabolism, was identified as a target. The inhibition of CPT1A in renal tubular epithelial cells led to impaired fatty acid oxidation and lipid accumulation. Excessive renal lipids further stimulated macrophages to transform into pro-inflammatory phenotypes, leading to renal inflammation infiltration and exacerbating kidney damage. Ergosterol upregulated CPT1A expression through transcriptional regulation of FOXA1, thereby reducing lipid accumulation and subsequent renal inflammation. <i>Conclusion</i>: Ergosterol enhances renal fatty acid oxidation <i>via</i> the FOXA1/CPT1A pathway, reducing renal lipid accumulation and inflammation, potentially delaying DKD progression. This study elucidates the therapeutic potential of ergosterol in DKD therapy and provides new insights into the treatment of this disease.</p>","PeriodicalId":77,"journal":{"name":"Food & Function","volume":" ","pages":""},"PeriodicalIF":5.1,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144697144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mucous layer, composed of mucin-2-based glycoproteins, is important for the intestinal barrier. Mucins are secreted by the goblet cells (GC), which are highly sensitive to endoplasmic reticulum (ER) stress. Therefore, promoting mucin synthesis and secretion by relieving ER stress is an effective way to enhance the intestinal mucus barrier. On the other hand, mucins are influenced by the gut microbiome. Mucin-associated bacteria can degrade mucins and then stimulate goblet cells to secrete mucin. Secoisolariciresinol diglucoside (SDG) has been reported to relieve ER stress and improve the gut barrier. As a prebiotic, fructooligosaccharide (FOS) has the potential to regulate intestinal flora. In the present study, we investigated the synergistic effect of SDG and FOS on the improvement of the intestinal mucus barrier in high-fat mice. It was found that both SDG and FOS alleviated histological damage in the colon, inhibited mRNA expression of proinflammatory cytokines, and improved the mucosal barrier. Notably, the synergistic treatment exhibited a better effect. Goblet cell differentiation was promoted, consistent with the relief of ER stress, and SDG might be superior in this process. FOS primarily regulated the gut microbiota, enriched mucus-associated bacteria, and increased the content of metabolite short-chain fatty acids (SCFAs). The simultaneous treatment displayed a synergistic effect. The results indicated that the synergistic treatment had a stronger effect on enhancing the intestinal mucus barrier from dual approaches of relieving ER stress and regulating gut microbiota.

On the basis of a series of our previous published studies that showed that black rice-based functional foods have multi-functional health benefits in rodents, including protection of mice and rats against inflammation and alcohol-induced hangovers, we were motivated to determine the protective effect of a polysaccharide-containing bioprocessed (fermented) black rice bran product (BRB-F) to prevent alcohol-induced liver damage.
