{"title":"Electrochemotherapy and Calcium Electroporation on Hepatocellular Carcinoma Cells: An In-Vitro Investigation.","authors":"K H K Lindelauf, M Baragona, T Lemainque, R T H Maessen, A Ritter","doi":"10.1007/s00270-024-03847-1","DOIUrl":"https://doi.org/10.1007/s00270-024-03847-1","url":null,"abstract":"<p><strong>Purpose: </strong>Electrochemotherapy, clinically established for treating (sub)cutaneous tumors, has been standardized in the framework of the European Standard Operating Procedure on Electrochemotherapy (ESOPE). Due to common side effects of chemotherapeutic drugs, recent advances focus on non-cytotoxic agents, like calcium, to induce cell death (calcium electroporation). Therefore, this study aims to determine the efficacy of electrochemotherapy with bleomycin or cisplatin, or calcium electroporation on human hepatocellular carcinoma cells (HepG2) in vitro using the ESOPE protocol.</p><p><strong>Methods: </strong>HepG2 cell viability was measured with a MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay after electrochemotherapy with the chemotherapeutic drugs bleomycin or cisplatin (0-20 µM), or after calcium electroporation (0-20 mM), to determine its efficacy on HepG2 cells in vitro using the ESOPE protocol (8 rectangular pulses, 1000 V/cm, 100 µs) compared to non-electroporated drug treatment.</p><p><strong>Results: </strong>Cell viability was significantly lower in electroporated samples, compared to their non-electroporated controls (27-75% difference). Electrochemotherapy with bleomycin and calcium electroporation, reached (almost) complete cell death (- 1 ± 3% and 2.5 ± 2%), in the lowest concentration of 2.5 µM and 2.5 mM, respectively. Electrochemotherapy with 2.5 µM cisplatin, significantly decreased cell viability to only 68% (± 7%).</p><p><strong>Conclusion: </strong>Electrochemotherapy with bleomycin or cisplatin, or calcium electroporation were more effective in reducing the HepG2 cell viability in vitro using the ESOPE protocol compared to the non-electroporated drug treatments alone. When comparing electrochemotherapy, HepG2 cells are more sensitive to bleomycin than cisplatin, in similar concentrations. Calcium electroporation has the same effectiveness as electrochemotherapy with bleomycin, but calcium potentially has a better safety profile and several treatment advantages.</p>","PeriodicalId":9591,"journal":{"name":"CardioVascular and Interventional Radiology","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142124918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
