In this study, we cultivated human primary UM cells and uveal melanoma-associated fibroblasts in vitro to be transduced by infection with a retrovirus containing the suicide gene\u2014fused yeast cytosine deaminase::uracil phospho-ribosyl transferase (yCD::UPRT). A homogenous population of yCD::UPRT-UM cells with the integrated provirus expressed the gene, and we found it to continuously secrete small extracellular vesicles (sEVs) possessing mRNA of the suicide gene. The yCD::UPRT-UM-sEVs were internalized by tumor cells to the intracellular conversion of the prodrug 5-fluorocytosine (5-FC) to the cytotoxic drug 5-fluorouracil (5-FU). The host range of the yCD::UPRT-UM-sEVs was not limited to UMs only. The yCD::UPRT-UM-sEVs inhibited the growth of the human cutaneous melanoma cell line A375 and uveal melanoma cell line MP38, as well as other primary UMs, to various extents in vitro. The yCD::UPRT-UM-sEVs hold the therapeutic and prophylactic potential to become a therapeutic drug for UM. However, the use of yCD::UPRT-UM-sEVs must first be tested in animal preclinical studies.<\/jats:p>","DOI":"10.3390\/ijms241612957","type":"journal-article","created":{"date-parts":[[2023,8,21]],"date-time":"2023-08-21T01:33:11Z","timestamp":1692581591000},"page":"12957","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Suicide-Gene-Modified Extracellular Vesicles of Human Primary Uveal Melanoma in Future Therapies"],"prefix":"10.3390","volume":"24","author":[{"given":"Jana","family":"Jakubechova","sequence":"first","affiliation":[{"name":"Cancer Research Institute, Biomedical Center, Slovak Academy of Sciences, 845 05 Bratislava, Slovakia"},{"name":"Stem Cell Preparation Department, St. Elisabeth Cancer Institute, 812 50 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4906-5652","authenticated-orcid":false,"given":"Bozena","family":"Smolkova","sequence":"additional","affiliation":[{"name":"Cancer Research Institute, Biomedical Center, Slovak Academy of Sciences, 845 05 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5689-892X","authenticated-orcid":false,"given":"Alena","family":"Furdova","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine, Comenius University, 814 99 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucia","family":"Demkova","sequence":"additional","affiliation":[{"name":"Cancer Research Institute, Biomedical Center, Slovak Academy of Sciences, 845 05 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ursula","family":"Altanerova","sequence":"additional","affiliation":[{"name":"Stem Cell Preparation Department, St. Elisabeth Cancer Institute, 812 50 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1989-7423","authenticated-orcid":false,"given":"Andreas","family":"Nicodemou","sequence":"additional","affiliation":[{"name":"Institute of Medical Biology, Genetics and Clinical Genetics, Faculty of Medicine, Comenius University, 814 99 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatiana","family":"Zeleznikova","sequence":"additional","affiliation":[{"name":"Stem Cell Preparation Department, St. Elisabeth Cancer Institute, 812 50 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Klimova","sequence":"additional","affiliation":[{"name":"Institute of Medical Biology, Genetics and Clinical Genetics, Faculty of Medicine, Comenius University, 814 99 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6998-0885","authenticated-orcid":false,"given":"Cestmir","family":"Altaner","sequence":"additional","affiliation":[{"name":"Cancer Research Institute, Biomedical Center, Slovak Academy of Sciences, 845 05 Bratislava, Slovakia"},{"name":"Stem Cell Preparation Department, St. Elisabeth Cancer Institute, 812 50 Bratislava, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"171","DOI":"10.1111\/j.1755-148X.2012.00979.x","article-title":"The genetics of uveal melanoma: An emerging framework for targeted therapy","volume":"25","author":"Harbour","year":"2012","journal-title":"Pigment.
