While bacteria and fungi inhabit honey and beehives, their roles in honey maturation remain unclear. In this study, we characterized the fermentation process of honey from Apis cerana japonica (Japanese honeybee) with respect to its microbial and flavor compound profiles. Metagenomic analysis revealed that the fungi in Japanese honeybee honey are dominated by Zygosaccharomyces siamensis, with minor members of Talaromyces, Oidiodendron, Starmerella, and Priceomyces. Fermentation of diluted raw honey increased the population of Z. siamensis. Inoculating honey with Z. siamensis produced aromatic compounds, including isoamyl alcohol, hotrienol, 2-phenylethanol, and 2-phenylethyl acetate, as well as the organic acid succinate. These results indicate that fermentation by Z. siamensis can generate favorable flavor compounds, offering the potential for enhancing honey's sensory qualities and applications in the food industry.</p>","PeriodicalId":9175,"journal":{"name":"Bioscience, Biotechnology, and Biochemistry","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143954453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

UVA promotes the production of reactive oxygen species (ROS), which damages dermal fibroblasts. ROS also induce the expression of matrix metalloproteinase-1 (MMP-1), an enzyme that degrades collagen leading to wrinkle formation. We focused on carotenoids, widely distributed natural antioxidants, to find candidate cytoprotective and anti-wrinkle agents. Canthaxanthin and fucoxanthin suppressed the UVA-induced decrease in cell viability. Fucoxanthin also suppressed ROS production; hence, this may be a molecular mechanism. In contrast, canthaxanthin significantly suppressed MMP-1 mRNA expression in UVA-irradiated fibroblasts without inhibiting ROS production. Subsequent analyses suggested that canthaxanthin could bind and inhibit p38 kinase activity by which it shows cytoprotective effect and inhibitory effect on MMP-1 mRNA expression. These two carotenoids may be potential agents for attenuating UVA-induced skin damage, and canthaxanthin may be a potential anti-wrinkle agent.</p>","PeriodicalId":9175,"journal":{"name":"Bioscience, Biotechnology, and Biochemistry","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143978375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, Kaplan-Meier plotter analysis demonstrated that patients with LUAD and low RASL10A expression have a poor prognosis. Furthermore, loss or gain of function experiments revealed that RASL10A suppresses transforming growth factor-beta (TGF-β)-induced epithelial-mesenchymal transition (EMT) and the subsequent invasion of LUAD A549 cells. In addition, we found that RASL10A suppresses Smad3 phosphorylation and Snail expression during the early stages of EMT.
