Herein, we conducted this study to analyze the expression profile of four circRNAs, including circCSPP1 (hsa_circ_0001806), circNRIP1 (hsa_circ_0004771), circSMAD2 (hsa_circ_0000847), and circFOXP1 (hsa_circ_0008234) in BC.Methods: Tumor tissues and adjacent normal tissues were obtained from patients with sporadic BC. Divergent primers were designed to amplify the target transcripts using quantitative real-time PCR. The expression profiles of circRNAs were analyzed in tumor and adjacent normal tissues. Sanger sequencing was performed to confirm the back-splicing junctions of circRNAs. ROC curves were generated to assess the potential of the mentioned RNAs as diagnostic biomarkers.Results: We observed a significant upregulation of circCSPP1, circNRIP1, and circSMAD2 in tumor tissue compared to adjacent normal tissues. Among them, circCSPP1 was the most highly upregulated one in tumor samples from 39 patients. Expression of circCSPP1 was significantly higher in ER-negative, PR-negative, HER2-negative, and triple-negatives compared to ER-positive, PR-positive, HER2-positive, and non-triple-negative ones. Expression of circNRIP1 was also significantly elevated in the ER-negative and the triple-negative subgroups. These three circRNAs also displayed a desirable potential as diagnostic biomarkers.Conclusion: This is the first paper that reports the upregulation of circCSPP1 and circSMAD2 in BC and upregulation of circCSPP1 and circNRIP1 in the triple-negative subgroup. Our findings suggest that circCSPP1, circNRIP1, and circSMAD2 may serve as promising diagnostic biomarkers for BC.

This study aimed to compare the effects of CRISPR-Cas9-mediated knockdown of BAX and caspase-3 genes on apoptosis inhibition, cell lifespan, and EPO production in CHO cell lines.Methods: The BAX and caspase-3 gene expression was evaluated in the rCHO cell lines producing EPO using the CRISPR-Cas9 method. Their anti-apoptotic effects and the level of EPO expression were also compared. In addition, OP as an apoptosis inducer, was introduced to the manipulated cell line to assess the stability and viability of the manipulated cell lines.Results: The rCHO cells with the manipulated BAX gene exhibited a higher cell density than those with the manipulated caspase-3 gene (152% vs. 142%). Despite the increased cell density in the cells with the BAX gene manipulation, EPO production was higher in the cells with the manipulated caspase-3 gene (1.58-fold increase in the BAX-manipulated cells compared to a 1.70-fold increase in the caspase-3-manipulated cells).Conclusion: Our observations suggest that the downregulation of the BAX and caspase-3 genes using the CRISPR method, inhibits apoptosis and enhances the yield of recombinant EPO, even in the presence of an apoptosis inducer.

The increasing emergence of FLZ resistance has led to higher morbidity and mortality rates. Streptomyces, a genus of Actinomycetes, produces bioactive molecules with antimicrobial effects. This study investigated the antifungal potential of S. monomycini strain 615 against FLZ-resistant C. albicans clinical isolates in vitro.Methods: S. monomycini strain 615 was cultured, and an aqueous crud extract containing its metabolites was prepared. The effects of extract were tested on five FLZ-resistant C. albicans isolates. Key pathogenic factors such as protease activity, biofilm formation, and gene expressions related to virulence (SAP1, SAP2, HWP1, and ERG11) and azole resistance (ERG11) were evaluated. Cytotoxicity of the extract (1.8-0.0008 µg/ml) was assessed on KYSE-30 esophageal epithelial cells using the MTT assay.Results: Strain 615 showed strong antifungal activity with MIC values of 0.0008-0.0035 µg/ml and MFC values of 0.0017-0.0035 µg/ml after 48 hours. The extract significantly reduced ergosterol content by 31.81%, completely inhibited phospholipase and proteinase activities at 0.0035 µg/ml and suppressed biofilm formation at 0.0035-0.0140 µg/ml. Expression of all tested virulence genes decreased except for ERG11, indicating a possible mechanism to overcome azole resistance. The highest extract concentration caused 76.7% cytotoxicity in KYSE-30 cells after 72 hours.Conclusion: S. monomycini strain 615 could serve as an alternative or adjunct therapy for FLZ-resistant OPC in head and neck cancer patients, warranting further research to confirm safety and efficacy.","PeriodicalId":14500,"journal":{"name":"Iranian Biomedical Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144093492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various assays, including cytotoxicity, cell viability, clonogenicity, flow cytometry, quantitative RT-PCR, and wound healing assays, evaluated the combined effects of QU and QU-SLN with cisplatin on cell viability, apoptosis, gene expression levels related to cisplatin resistance, and cell migration.Results: Combining QU-SLN with cisplatin resulted in significantly reduced cell viability and colony formation, accompanied by increased apoptotic rates compared to each treatment alone. Moreover, there was a notable reduction in the expression level of genes associated with cisplatin resistance, particularly ABCG2, MT-2A, GST-pi, and XIAP, in the combined treatment. Wound healing assays indicated that the QU-SLN and cisplatin combination severely impaired OC cell motility compared to cisplatin monotherapy.Conclusion: QU-SLN and cisplatin combination enhances the therapeutic response in cisplatin-resistant OC cells.

These epitopes were selected based on their high density of both B-cell and T-cell epitopes. The construct of the vaccine candidate was inserted into a pEGFP-N1 vector and introduced into HEK-293T cells. Subsequently, the vaccine was tested on different groups of mice; some received the expressed protein in E. coli, while others received the DNA vaccine candidate. An ELISA assay was employed to evaluate the humoral immune response.Results: Both the MEB protein (Pro/Pro) and pCI-MEB plasmid/MEB protein (DNA/Pro) groups showed a specific humoral response. The anti-DNA vaccine antibody titer did not rise as high as that of the protein groups; however, the observed protection indicated the efficiency of the DNA vaccine in activating the immune system.Conclusion: While the chimeric DNA vaccine candidate induced a weaker humoral response, it remained effective in protecting against virulent strains of B. abortus and B. melitensis in the challenge route.","PeriodicalId":14500,"journal":{"name":"Iranian Biomedical Journal","volume":"29 1 & 2","pages":"36-48"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12040634/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143996201","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}

Oncolytic viruses (OVs) present a potential treatment option for solid tumors. Newcastle disease virus (NDV) is one of the most promising OVs that can replicate within and destroys human cancer cells. This study aimed to evaluate the cytotoxic and apoptotic effects of the NDV strain on human PCa cells in vitro. Additionally, We examined a novel treatment for PCa by combining Lenalidomide (Len) with NDV.Methods: NDV strains La Sota, B1, and I2 were tested for cytotoxicity against several cell lines. A safety assessment was conducted in primary cells using peripheral blood mononuclear cells (PBMCs). Also, apoptosis induction was measured using annexin V/7AAD staining. Finally, the cytotoxic effects of NDV alone and in combination with Len, were assessed using MTT.Results: The NDV showed cytotoxic effects on tumor cell lines and induced apoptosis in infected prostate cells compared to control cells. The NDV La Sota strain exhibited significant oncolytic capacity, reducing the viability of LNCaP and DU145 cells to less than 40% at specific concentrations, while showing no cytotoxic effects on primary PBMCs. Also, NDV induced apoptosis in the prostate cell line by 60%. Furthermore, Len enhanced the cytotoxicity of PCa cells when combined with NDV.Conclusion: Our study confirms the efficacy of oncolytic NDV treatment for PCa, particularly utilizing the La Sota strain. When combined with Len, NDV indicates an enhanced effectiveness in destroying tumor cells. These findings suggest a prospective treatment approach that needs more preclinical and clinical studies to improve outcomes in PCa treatment.","PeriodicalId":14500,"journal":{"name":"Iranian Biomedical Journal","volume":"29 1 & 2","pages":"9-19"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12040631/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144005037","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}
