We found that nobiletin regulates cytokine production from T cells. In this study, we examined the mechanism for enhancement of interleukin (IL)-4 production by nobiletin. We investigated the key molecules for production of IL-4 by deep data-based analysis and we identified nine candidate genes. The mRNA expression levels of <i>c-Maf</i>, <i>Gata-3</i>, <i>Nfat4</i>, and <i>Pparg</i> genes were significantly elevated by treatment with nobiletin. From RNA sequence analysis, the T helper type 1 (Th1) and Th2 differentiation pathway was shown to be dominantly affected by nobiletin. Furthermore, molecular network analysis showed that GATA-3 is one of the candidate molecules for enhancement of IL-4 production. Treatment of splenocytes including antigen-presenting cells with nobiletin was sufficient for the induction of IL-4 production from DO11.10 mouse CD4⁺ T cells. Treatment of B cells and dendritic cells with nobiletin induced IL-4 production from CD4⁺ cells. Splenocytes from DO11.10 mice that had been treated with nobiletin produced more IL-4 than did splenocytes from control mice.

Possible mechanisms underlying this morphological change include dysruption of calcium homeostasis, increased membrane oxidation, and destabilization of cytoskeletal proteins. However, the detailed mechanisms leading to neuronal damage has not been elucidated. Calcium plays an important role in neuronal changes caused by oxidative stress. Mitochondria and endoplasmic reticulum (ER) play roles in intracellular calcium storages. One mechanism of neurite degeneration associated with oxidative stress may be related to calcium-mediated interactions between mitochondria and ER. In this study, we evaluated intracellular calcium homeostasis, mitochondria, and ER localization when neurite degeneration was induced in neuroblastoma cells that had extended neurites. Treatment with hydrogen peroxide (H₂O₂) and the calcium ionophore ionomycin induced mitochondria-dependent superoxide production and membrane oxidation. When examining the involvment of calcium efflux from the ER and mitochondria, treatment with a ryanodine receptor inhibitor ruthenium red significantly reduced intracellular calcium concentrations in ionomycin-treated cells. Electron microscopy in neurite degeneration areas revealed numerous fragmented mitochondria in ionomycin-treated cells, and mitochondrial swelling was observed in the same area of H₂O₂-treated cells. Next, we investigated proteins related to fusion and fission by western blotting. However, mitochondrial dysfunction occurs in both cases and is therefore thought to be associated with neurite degeneration. Our results suggest that H₂O₂ and ionomycin cause neurite degeneration via different mechanisms. Interactions between mitochondria and the ER through unknown crosstalk pathways and calcium transfer may play an important role in maintaining neurite function.</p>","PeriodicalId":15429,"journal":{"name":"Journal of Clinical Biochemistry and Nutrition","volume":"76 3","pages":"253-263"},"PeriodicalIF":2.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12152244/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144284533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this work is to investigate the regulatory impacts of β-elemene on obesity progression and associated pathways. In this study, it was revealed that the heightened lipid accumulation in 3T3-L1 cells triggered by 3-isobutyl-1-methylxanthine + dexamethazone + insulin (MDI) can be restrained by β-elemene. Furthermore, β-elemene can modulate lipid metabolism in 3T3-L1 cells mediated by MDI. The glucose consumption was descended after insulin resistance treatment, but this impact was reversed after β-elemene treatment. At last, it was illustrated that the AMPK pathway was retarded after β-elemene induction, but this change was offset after β-elemene treatment.
