Besides its variety of beneficial effects, it was reported to exert anticancer effects. Despite its utilization against different cancer types, the effect of ASX on mesothelioma has yet to be well\u2010studied. In this study, our goal is to ascertain how ASX will affect SPC212 human mesothelioma cells. First, the effective doses of ASX against SPC212 cells were investigated by the 3\u2010(4,5\u2010dimethylthiazol\u20102\u2010yl)\u20102,5\u2010diphenyltetrazolium bromide (MTT) test. Thereafter, with flow cytometry analysis, Annexin\u2010V and caspase 3\/7 assay were implemented for the evaluation of apoptotic cell death and an oxidative stress test was carried out to determine how the free radicals changed. Ultimately, the cells' morphology was examined under a light microscope. The effective doses of ASX were found as 50, 100, and 200\u2009\u00b5M. In the Annexin V assay, the total apoptosis increased to around 12%, 30%, and 45% with increasing doses of ASX. In the caspase 3\/7 assay, the total apoptosis was around 25% and 38% at 100 and 200\u2009\u00b5M. In oxidative stress analysis, reactive oxygen species\u2010positive cells rose from 4.54 at the lowest dose to 86.95 at the highest dose. In morphological analysis, cellular shrinkage, decrease in cell density, swelling and vacuolations in some cells, membrane blebbing, and apoptotic bodies are observed in ASX\u2010treated cells. To conclude, the current study provided insights into the efficacy and effects of ASX against SPC212 mesothelioma cells regarding morphology, proliferation, and cell death for future studies.<\/jats:p>","DOI":"10.1002\/jbt.23415","type":"journal-article","created":{"date-parts":[[2023,6,24]],"date-time":"2023-06-24T18:13:21Z","timestamp":1687630401000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["SPC212 human mesothelioma cells underwent apoptosis, oxidative stress, and morphological deformation following Astaxanthin treatment"],"prefix":"10.1002","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0671-8529","authenticated-orcid":false,"given":"Sedat","family":"Ka\u00e7ar","sequence":"first","affiliation":[{"name":"Department of Surgery, Indiana Center for Regenerative Medicine and Engineering Indiana University School of Medicine Indianapolis USA"},{"name":"Department of Histology and Embryology, Faculty of Medicine Eski\u015fehir Osmangazi University  Eski\u015fehir Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4856-2304","authenticated-orcid":false,"given":"Tu\u011fba","family":"Semerci Sevimli","sequence":"additional","affiliation":[{"name":"Department of Cellular Therapy and Stem Cell Production, Application and Research Center (ESTEM) Eski\u015fehir Osmangazi University Eski\u015fehir Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2317-3644","authenticated-orcid":false,"given":"Varol","family":"\u015eahint\u00fcrk","sequence":"additional","affiliation":[{"name":"Department of Histology and Embryology, Faculty of Medicine Eski\u015fehir Osmangazi University  Eski\u015fehir Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,6,22]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"63","volume":"7","author":"Patel S.
