Probiotics, recognized for their antioxidant properties, may provide a beneficial approach to mitigate this oxidative damage. This research aims to explore the efficacy of native probiotics in reducing oxidative stress in kidney tissues, potentially leading to improved protective strategies against the toxicity caused by heavy metals. In this study, forty male NMRI mice were exposed to Nickel to induce oxidative stress, followed by probiotic treatment to evaluate its potential protective effects. The impact of these interventions on the antioxidant system was assessed through Real-Time PCR analysis, which measured gene expression profiles in the kidney tissue of the mice. The study demonstrated that native probiotic strains effectively upregulated the expression of genes related to Nrf2 signaling pathway before exposing to oxidant agents. Despite the suppressive effects of Nickel exposure on these gene expressions, the subsequent administration of probiotics after Nickel resulted in a significant increase and enhancement of expression levels. This research underscores the detrimental effects of Nickel, a heavy metal, on kidney health while exploring the protective properties of probiotics, particularly their anti-oxidative effects. Given the substantial risks linked to heavy metal exposure, the integration of probiotics presents a promising strategy to alleviate oxidative stress, thereby potentially preventing various kidney disorders associated with this condition. The findings advocate for a dual approach of addressing heavy metal toxicity and enhancing kidney resilience through probiotic intervention.","PeriodicalId":491,"journal":{"name":"Biometals","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787665","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}

In the mouth cavities, trachea, and catheters, Candida glabrata biofilm grows unhindered and is the primary etiological factor in the pathophysiology of candidiasis, in the worst cases, this leads to systemic infections. Therefore, developing novel biofilm preventative and therapeutic agents is urgently required. Here, in the present study, an effort was made to monitor the function of silver nanoparticles (AgNPs) generated from a cyanobacterium (Anabaena variabilis) as a novel antibiofilm agent focusing on candidiasis. Anabaena variabilis cell extract was used to synthesize AgNPs, characterized by UV-visible spectroscopy. The minimum inhibitory concentration (MIC) of AgNPs was observed at 25 µg/mL in Candida glabrata. At the concentration of 2MIC of AgNPs (50 µg/mL), 67 ± 0.84% membrane permeability was noticed at the same concentration the viable cells were found at only 2.8 ± 2.0%; while in the early phase of apoptosis, were found at 15.5 ± 1.5%; and in the late phase of apoptosis, were found at 81.8 ± 4.2%, thus confirming the cell's death. Additionally, a cell-cycle study also declared the halted cycle in the S phase by increasing the number of cells. The growth inhibition assay shows that the test organism's growth steadily decreased in comparison to the control with increasing AgNPs concentrations. Additionally, in the scanning electron microscopic pictures of Candida glabrata treated with AgNPs, which exhibited deep wrinkles and deformity, confirming the cells death. At the concentrations of 2MIC of AgNPs (50 µg/mL) showed 72 ± 0.86% of biofilm inhibition and 80 ± 1.3% degradation during the biofilm study. In conclusion, all results demonstrate that AgNPs have great antifungal potential; therefore, AgNPs could be used to control biofilm produced by emerging multidrug-resistant Candida glabrata.","PeriodicalId":491,"journal":{"name":"Biometals","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787608","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}

This study evaluates and compares the antifungal efficacy of biologically synthesized zinc oxide nanoparticles (ZnO-NP-B) and chemically synthesized ZnO nanoparticles (ZnO-NP-C1 and ZnO-NP-C2), developed using the dry-wet chemical method and sol-gel method, respectively. ZnO-NP-B was synthesized using Lactobacillus gasseri. The nanoparticles were characterized for size, charge, and morphology using Particle Size Analyzer, photon correlation spectroscopy with a 90 Plus Zetasizer, and scanning electron microscopy (SEM), respectively. The antifungal activity was assessed through minimum inhibitory concentration (MIC50) determination, biofilm inhibition assays by XTT assay, and gene expression analysis. ZnO-NP-C1 exhibited the highest antifungal activity against C. auris planktonic cells, with a MIC50 value of 61.9 ± 3.3 µg/ml, followed by ZnO-NP-C2 (151 ± 7.83 µg/ml), whereas ZnO-NP-B showed limited efficacy (MIC50 = 1 mg/ml). Chemically synthesized ZnO-NPs, particularly ZnO-NP-C2, did not induce overexpression of resistance genes (CDR1, MDR1, ERG2, ERG11, FKS1, CHS1), whereas ZnO-NP-B triggered their upregulation, potentially promoting resistance. ZnO-NP-C1 was the most effective in preventing biofilm formation, reducing C. auris adhesion by 67.9 ± 2.35% at 150 µg/ml, while ZnO-NP-B exhibited negligible inhibition. Gene expression analysis further confirmed that ZnO-NP-C1 significantly downregulated adhesive genes (ALS5, IFF4, CSA1) by up to 0.37 ± 0.006, 0.043 ± 0.002, and 0.06 ± 0.0004, respectively.
