We investigated the susceptibility of phenotypically distinct C. auris isolates to sodium hypochlorite (NaOCl), and evaluated the role of biofilms in surviving disinfection using a dry-surface biofilm (DSB) model and transcriptomic profiling. Planktonic cells were tested for susceptibility to NaOCl, with biofilm formation using the 12-day DSB model, assessed using viable counts, biomass assays and microscopy. Disinfection efficacy was assessed using clinical protocols of 500–1,000 ppm for 1–5 min. RNA sequencing was performed on untreated DSBs in comparison to planktonic cells. Isolates were found to be susceptible planktonically, but grew NaOCl-tolerant biofilms, with only 2–4 log10 reductions in viable cells observed at highest concentrations. Transcriptomics identified DSB upregulation of ABC transporters and iron acquisition pathways relative to planktonic cells. Our findings optimized a DSB protocol in which C. auris can mediate tolerance to NaOCl disinfection, suggesting a lifestyle through which this problematic yeast can environmentally persist. Mechanistically, it has been shown for the first time that upregulation of small-molecule and iron transport pathways are potential facilitators of environmental survival.","PeriodicalId":8167,"journal":{"name":"Apmis","volume":"133 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/apm.70022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793499","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}

Aurora kinase B (AURKB), a critical regulator of mitosis, has been implicated in cancer progression, though its precise role in HCC remains unclear. In this study, AURKB expression was found to be significantly elevated in HCC tissues and cell lines compared to controls, as validated by GEPIA and ENCORI databases. Functional assays revealed that AURKB knockdown reduced cell proliferation, invasion, and migration, while increasing apoptosis. Furthermore, suppression of AURKB affected epithelial-mesenchymal transition (EMT) markers, decreasing vimentin and N-cadherin levels and increasing E-cadherin expression. In vivo, a xenograft mouse model demonstrated that tumors derived from AURKB-silenced cells exhibited reduced growth and fewer lung metastases. Histological and immunohistochemical analyses showed lower levels of Ki-67, MMP-9, and EMT markers in these tumors, alongside increased E-cadherin. These findings highlight AURKB's critical role in promoting HCC progression, metastasis, and EMT regulation. Overexpression of AURKB was associated with poor prognosis, suggesting it could serve as a potential biomarker and therapeutic target for liver cancer. Overall, targeting AURKB may provide a novel approach to inhibit HCC growth and metastasis, improving patient outcomes.\u0000 </div>","PeriodicalId":8167,"journal":{"name":"Apmis","volume":"133 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762159","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}

Kurarinone decreased MPO activity (47.6%, p < 0.001) and alleviated the inflammatory response by reducing the levels of IL-1β (34.9%, p < 0.001), TNF-α (55.1%, p < 0.001), and IL-6 (36.2%, p < 0.001) in the lung.

A total of 171 patients were included in the study. Forty-five patients had 54 CRBSI episodes. The average time between catheter placement and the development of CRBSI was 127.4 days, and the risk of developing CRBSI increased as this duration extended. In the bivariate logistic regression analysis, advanced age (p = 0.03), diabetes (p = 0.005), duration of hemodialysis (p < 0.001), decompensated cirrhosis (p = 0.02), and the femoral vein being the entry site (p = 0.011) were identified as risk factors for CRBSI.
