Thirty-two healthy female Wistar albino rats (250-300 g weight and 3-4 months) were randomly distributed into four equal groups (n = 8): control, high fructose % 20 (HF), boric acid 20 mg/kg (BA), and HF + BA. High fructose was freshly prepared and administered to the rats as 20 g of D-fructose dissolved in 100 mL of tap water daily for a duration of 30 days.

This investigation is designed as a case-control study, concentrating on community members aged 60 years and older who underwent physical assessments and had their whole blood iron levels tested at local health service centers from April to September 2021. In total, 786 participants qualified for inclusion in the study. Individuals diagnosed with fatty liver were organized into the NAFLD group (393 cases), while the control group (393 cases) consisted of healthy individuals who participated in physical evaluations during the same timeframe. Whole blood iron levels and other pertinent biochemical markers were assessed for both groups, alongside the collection of general demographic data. The results indicated that the whole blood iron concentration in the fatty liver cohort [(483.42 ± 45.59) mg/L] was significantly elevated compared to the control group [(470.16 ± 47.76) mg/L]. Moreover, levels of whole blood iron, whole blood zinc, whole blood magnesium, and serum low-density lipoprotein cholesterol were all significantly greater in the fatty liver group than in the control group. The multivariate logistic regression analysis demonstrated that, after adjustments for confounding variables such as age and sex, the odds ratio (OR) (95% confidence interval [CI]) for the occurrence of fatty liver in the lowest whole blood iron quartile (Q1) relative to the highest quartile (Q4) was 0.44 (95% CI: 0.25, 0.76). This research demonstrates a strong link between whole blood iron levels and the development of fatty liver within this community. Tracking whole blood iron concentrations could be crucial for the early detection and intervention of fatty liver.

The aryl hydrocarbon receptor (AhR) is expressed in breast cancer cells and linked to disease progression, while Notch signaling enhances migratory properties in these cells. The simultaneous use of the AhR agonist (FICZ), AhR antagonist (CH223191), and Notch antagonist (DAPT) was intended to investigate how the modulation of these pathways affects the response of breast cancer cells (MDA-MB-231 and MCF-7 cell) to ATO. We measured cell viability, reactive oxygen species (ROS) levels, mitochondrial membrane potential (MMP), and cell migration. Results show that ATO significantly reduces cell viability in a dose- and time-dependent manner, decreasing MMP and increasing ROS levels. Notably, co-exposure to ATO and CH223191 for 24 h enhanced cell viability, increased MMP, and diminished ROS compared to ATO alone. Also, the ATO + CH223191 + DAPT combination exhibited higher MMP and lower ROS levels than the ATO + FICZ + DAPT combination, indicating AhR inhibition's critical role in MMP regulation. Although ATO reduced migration compared to controls, adding DAPT or FICZ significantly increased migration percentages. Interestingly, co-exposure to CH223191 did not exhibit this effect and modulated the migratory effects of DAPT + ATO and FICZ + ATO combinations. In conclusion, these findings suggest that AhR stimulation via FICZ may enhance ATO's therapeutic effects, while simultaneous exposure to ATO, FICZ, and DAPT may lead to additive effects, reducing MMP and increasing ROS levels.</p>","PeriodicalId":8917,"journal":{"name":"Biological Trace Element Research","volume":" ","pages":"5170-5182"},"PeriodicalIF":3.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143490620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the health threats from long-term low-dose Cd exposure, this knowledge gap is especially concerning. It is thus important to systematically examine how Cd concentration in dietary rice affects Cd-RBA and to assess the regulatory impact of Fe on Cd-RBA. A mouse experiment was conducted using rice feed with four Cd levels and five Fe levels, and the Cd concentrations in the faces, blood, and urine were determined. Fe addition to rice feed inversely correlated with Cd concentrations in mouse organs. Increasing Fe from 150 to 200 mg/kg significantly reduced Cd concentrations (p < 0.05) and lowered Cd relative bioavailability (RBA). Cd excretion through feces mirrored organ accumulation. Blood Cd levels were very low and inversely proportional to Fe concentration (R² = 0.71-0.97). Cd-RBA negatively correlated with Cd level in rice (R² = 0.38-0.96). Liver and kidney had similar Cd-RBA values, but kidneys were more sensitive to low-dose Cd, needing further study on the mechanisms. At 150 to 200 mg/kg Fe, some organs still had increased Cd accumulation and Cd-RBA, possibly due to Cu transport proteins (ATP7A). Urine Cd concentrations remained low and did not correlate linearly with Cd or Fe levels in rice feed, likely due to low Cd levels in experimental rice. It was revealed that there was an overall negative correlation between Cd-RBA and Cd level in rice and confirmed that higher levels of Fe can effectively inhibit the body's absorption of Cd, thereby regulating Cd-RBA in rice. The mechanism is that a high level of Fe inhibits the transport of Cd in intestinal epithelial cells and promotes its efficient excretion from the body with feces. This is confirmed by the corresponding changes in organ Cd enrichment and fecal Cd concentration.</p>","PeriodicalId":8917,"journal":{"name":"Biological Trace Element Research","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145198034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
