To address this issue, we directly compared the impacts of BPA, BPF, and BPS in the same <i>in vivo</i> exposure study. Briefly, 8-week-old male Fischer rats were exposed to BPA, BPF, or BPS (at five different doses) and to 17α-ethinylestradiol (positive control for estrogenicity) by gavage for 28 consecutive days. Rat health, dietary intakes, and weight gains were monitored, 24-hour urine samples were collected, and blood and tissues were harvested at the terminal necropsy. The impacts of BPA, BPF, and BPS on rat weight gains, organ weights and histology, liver enzymatic activities, hematology, clinical chemistry, and serum hormone levels were relatively modest and mostly limited to the highest doses administered. However, bisphenol cross-contamination observed in urine samples from the vehicle control group may have interfered with the evaluation of their effects at lower doses. Although BPA, BPF, and BPS exposures all shared similarities with the 17α-ethinylestradiol positive control group, their impacts on serum hormone levels and endocrine-responsive tissues also presented noticeable differences. This suggests that BPA, BPF, and BPS may interfere with endocrine functions through slightly different molecular mechanisms.</p>","PeriodicalId":14432,"journal":{"name":"International Journal of Toxicology","volume":" ","pages":"10915818251378990"},"PeriodicalIF":1.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145086110","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}

Recent evidence suggests a correlation between metabolic disorders, particularly diabetes, and PD pathogenesis through the gut-brain axis. Methylglyoxal (MGO), a glucose-derived metabolite produced by gut bacteria such as <i>Proteus mirabilis</i>, is implicated in protein misfolding and glycation. This study investigated whether MGO induced α-synuclein aggregation in intestinal enteroendocrine cells and explored the underlying mechanisms. Mouse enteroendocrine STC-1 cells were treated with MGO (0.01-1 mM) for 36 h, and changes in α-synuclein aggregation, neuronal markers, and relevant signaling pathways were assessed. MGO at 1 mM significantly reduced cell viability and neuronal marker expression, and concentrations of 0.1 and 1 mM increased α-synuclein aggregation. MGO also inhibited SIRT1 expression, leading to increased Hif-1α transcription and reduced expression of autophagy-related proteins Beclin1 and LC3B. These changes were accompanied by mitochondrial dysfunction, as evidenced by decreased Bcl2, increased cytochrome C expression, and reduced levels of the antioxidant factor HO-1. Our findings provide the first evidence that MGO directly induces α-synuclein aggregation in enteroendocrine cells via the SIRT1-Hif-1α-autophagy pathway dysregulation, establishing a potential mechanistic link between gut microbiome-derived metabolites and PD pathogenesis.

Although PEGs are considered biologically inert with a low toxicity, anti-PEG antibodies have been detected in patients receiving treatment with PEGylated biotherapeutics as well as in healthy individuals. Despite continual exposure in daily life, the prevalence of PEGs within the general population remains unclear. This study aimed to evaluate a healthy population for the presence of PEGs. A validated enzyme-linked immunosorbent assay (ELISA) platform was used to analyze 200 plasma samples from healthy adults for the presence of PEGs. High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was also used to analyze the samples for the presence of four PEG analytes: PEG3350; PEG4000; PEG10000; and PEG2ru20K COOH, a 20 kDa PEG used to modify therapeutic proteins. The detection limit for PEG3350 calculated by extrapolation with linear regression was assumed to be 3.60 ng/mL. PEG levels above the lower limit of quantification (LLOQ) (21.6 ng/mL) were detected in 41 plasma samples, range 22.1-43.9 ng/mL, using the ELISA platform. None of the samples were found to contain detectable levels of PEG4000, PEG10000, or PEG2ru20K COOH. Following extrapolation, PEG3350 levels above the LLOQ (3.60 ng/mL) were detected in 154 plasma samples, range 3.69-46.0 ng/mL.
