In this study, the cytogenotoxic potential of gadoteric acid in NIH3T3 fibroblast cells was evaluated using in\u00a0vitro and in silico approaches. NIH3T3 cells were treated with increasing concentrations of gadoteric acid. Cytotoxicity was evaluated by MTS assay and genotoxicity by comet assay; hydrogen peroxide (75\u2009\u03bcM) was used as a positive control. In addition, the interaction of gadoteric acid with DNA topoisomerase II\u03b1, DNA topoisomerase II\u03b2, DNA polymerase \u03b2, and B\u2010DNA was examined by molecular docking. MTS assay results showed a dose\u2010dependent decrease in cell viability with an IC\n                    <jats:sub>50<\/jats:sub>\n                    of 28.19\u2009mM. Comet assay revealed significant DNA damage only at the highest concentration (56.38\u2009mM) (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.05), which also caused marked cytotoxicity. Thus, the observed DNA damage likely resulted from cytotoxicity stress rather than direct strand breaks. In silico docking predicted a high binding affinity of gadoteric acid for DNA polymerase \u03b2 (\u221211.7\u2009kcal\/mol) and other DNA\u2010related targets. However, these predictions require experimental validation. Overall, gadoteric acid exhibited dose\u2010dependent cytotoxicity and limited genotoxicity at high concentrations, suggesting that DNA damage occurs secondary to cytotoxic effects rather than a direct genotoxic mechanism.\n                  <\/jats:p>","DOI":"10.1111\/bcpt.70150","type":"journal-article","created":{"date-parts":[[2025,12,4]],"date-time":"2025-12-04T09:21:02Z","timestamp":1764840062000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Gadoteric Acid Induces Dose\u2010Dependent DNA Damage and Enzyme Binding in Fibroblast Cells"],"prefix":"10.1111","volume":"138","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9848-954X","authenticated-orcid":false,"given":"\u0130brahim\u00a0Halil","family":"Kenger","sequence":"first","affiliation":[{"name":"Medical Genetics Gaziantep Islamic Science and Technology University  Gaziantep Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,4]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/741018"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.2217\/iim.12.34"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/249810"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/0284185120920801"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.rli.0000113776.87762.49"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmri.26031"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfk062"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.00379.2014"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/mrm.28060"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.13131669"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.1056\/nejmcpc0708697"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1186\/s41021\u2010020\u201000161\u20103"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jes.2017.03.032"},{"key":"e_1_2_12_15_1","volume-title":"The Role of DNA\u2010Fragmentation in Contrast\u2010Induced Tubular Cell Damage","author":"Dikopoulos J.
