In this study, we investigated the relationship between acylhomoserine lactone (AHL)-mediated quorum sensing and pathogenicity in 21 TPN isolates, which were classified into three groups: Group 1 (Pseudomonas corrugata), Group 2 (Pseudomonas mediterranea), and Group 3 (novel taxonomic group). All strains produced N-hexanoyl-l-homoserine lactone as the dominant AHL molecule. Phylogenetic analyses revealed high conservation of quorum-sensing genes among the three groups, with nearly identical sequences and arrangements. Whole genome sequencing of the Group 3 strain MAFF 730105 revealed the presence of a Type III secretion system gene cluster, similar to well-known plant pathogens. Although quorum sensing influences virulence, its impact is limited, and some virulence factors may be constitutive or regulated independently. These results suggest that quorum sensing contributes to TPN symptoms; however, additional factors and regulatory mechanisms are involved in the pathogenicity of TPN isolates.</p>","PeriodicalId":9175,"journal":{"name":"Bioscience, Biotechnology, and Biochemistry","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144599405","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}

Based on these results, human intestinal organoids can now be cultured on a large scale at a significantly lower cost, which enables compound screening, including screening of drug candidates that exhibit cytotoxicity, which may lead to intestinal toxicity.

UVA promotes the production of reactive oxygen species (ROS), which damages dermal fibroblasts.

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 a cytoprotective effect and an inhibitory effect on MMP-1 mRNA expression.
