The Prognostic Nutritional Index (PNI) reflects nutritional and inflammatory status and is a well-known prognostic factor. We therefore aimed to evaluate and compare the prognostic role of PNI in patients with HCC with and without concurrent MASLD undergoing curative surgical resection. In our retrospective study, 991 patients undergoing curative HCC resection were stratified according to MASLD status and pre-operative PNI (cut-off: 45). Overall survival (OS) and recurrence-free survival (RFS) were analyzed using Kaplan-Meier methods and Cox proportional hazards models. Further subgroup analysis was performed according to their concurrent viral hepatitis status. High PNI was identified as an independent protective factor against poor OS for the entire cohort (hazard ratio [HR]: 0.65; 95% confidence interval [CI]: 0.49-0.87, p = 0.004). The Kaplan-Meier analysis showed that the high-PNI/MASLD group had the best OS, while the low-PNI/no-MASLD group had the worst. Subgroup analysis indicated that high PNI was an independent protective factor for OS only in the no-MASLD group (HR: 0.59, p = 0.003) but not the MASLD group (HR: 0.94, p = 0.793). Its prognostic effect was more significant in HCC patients without concurrent MASLD or with chronic hepatitis B. To conclude, a better nutritional status, assessed by PNI, is a valuable prognostic marker for patients with HCC. Its protective effect on OS is significantly pronounced in patients without concurrent MASLD, indicating that MASLD status modifies the prognostic utility of PNI.</p>","PeriodicalId":94244,"journal":{"name":"The Kaohsiung journal of medical sciences","volume":" ","pages":"e70256"},"PeriodicalIF":3.1,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13399853/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148383453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We identified 1981 significantly up-regulated and 4952 down-regulated differentially expressed genes (DEGs) in CSE-treated airway epithelial cells. A protein-protein interaction network constructed from the DEGs revealed that several key genes were involved in CSE-induced airway epithelial injury.

PDCD5 silencing significantly attenuated CSE-induced mitochondrial reactive oxygen species (ROS) accumulation, mitochondrial membrane potential loss, and intracellular ATP depletion. Transmission electron microscopy revealed that PDCD5 siRNA treatment ameliorated CSE-induced mitochondrial structural damage. Moreover, PDCD5 knockdown significantly reduced intracellular ROS accumulation, attenuated apoptosis increases, and inhibited cell viability decline in airway epithelial cells treated with CSE.

In this study, we found that FTO expression was significantly upregulated in patient samples and DLBCL cell lines. Functional assays showed that FTO knockout or knockdown suppressed cell proliferation and colony formation, whereas FTO overexpression promoted tumor growth and increased ibrutinib half-maximal inhibitory concentration. Mechanistically, FTO directly bound to myelocytomatosis oncogene (Myc) mRNA and removed m6A modifications, stabilizing Myc transcripts and enhancing Myc protein expression. Methylated RNA immunoprecipitation-quantitative polymerase chain reaction confirmed that FTO knockout increased m6A enrichment on Myc mRNA, leading to decreased Myc stability. Rescue experiments showed that reintroducing Myc partially restored the proliferative and drug-resistant phenotype of FTO-deficient cells. Consistently, in xenograft models, FTO promoted tumor growth and ibrutinib resistance in a manner partly dependent on Myc. Overall, FTO promotes DLBCL progression and ibrutinib resistance by demethylating Myc mRNA and stabilizing its expression.

Candidate variants were validated by Sanger sequencing and assessed for segregation. Pathogenicity was evaluated through comprehensive in silico analysis and the application of ACMG/AMP guidelines. Analysis revealed two clinically significant variants. In Family 1, we identified a heterozygous stop-gain variant in MLH1 (c.1043T>A, p.Leu348), a known pathogenic mutation consistent with Lynch syndrome. In Family 2, we discovered a previously undocumented heterozygous missense variant in ERBB2 (c.2268G>T, p.Arg756Ser). Through a detailed ACMG assessment, this ERBB2 variant was classified as Likely Pathogenic based on its location in a critical tyrosine kinase domain, absence from population databases, and concordant deleterious in silico predictions.
