We examined whether low-dose BPA alters redox regulation linked to ferroptosis susceptibility in 786-O and ACHN cells. After concentration screening, 100 nM BPA was used for mechanistic experiments. BPA enhanced proliferation and migration, increased the glutathione redox ratio (GSH/GSSG), reduced reactive oxygen species (ROS) signals, and preserved mitochondrial membrane potential. Public cancer dataset analyses prioritized SLC7A11, which was upregulated by BPA at mRNA and protein levels. Under inhibition of the cystine/glutamate antiporter system xc− with erastin, BPA co-treatment partially attenuated cytotoxicity and functional suppression. BPA increased NF-κB p65 phosphorylation, and pyrrolidine dithiocarbamate reduced p-p65 and SLC7A11 expression. These findings suggest that environmentally relevant BPA exposure may promote stress-tolerant phenotypes in RCC cells via an NF-κB–SLC7A11–associated antioxidant response.</div></div>","PeriodicalId":11775,"journal":{"name":"Environmental toxicology and pharmacology","volume":"124 ","pages":"Article 105045"},"PeriodicalIF":4.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147984804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Insecticides comprised a minority of detections and concentration. Due to their heightened toxicity, insecticides contributed substantially to hazard quotients with one residue, the neonicotinoid imidacloprid, contributing 99.9% to overall HQ. We found both high prevalence and high levels of imidacloprid in adult bee bodies. Additionally, we preserved a small subsample of dying bees. Our findings highlight a survivorship bias, where dying bees had active ingredients known to have acute toxicity to bees. This result mirrors recent evidence for viral drivers of bee declines that were missed in whole-colony surveys. While bees die from multiple, often interacting, stressors, here we show single contributors at levels capable of causing acute harm.</div></div>","PeriodicalId":11775,"journal":{"name":"Environmental toxicology and pharmacology","volume":"124 ","pages":"Article 105048"},"PeriodicalIF":4.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148102155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
