Abstract: Natural compounds hold great promise for combating antibiotic resistance, the failure to control somediseases, the emergence of new diseases and the toxicity of some contemporary medical products. Allylisothiocyanate (AITC), which is abundant in cruciferous vegetables and mustard seeds and is commonlyreferred to as mustard essential oil, exhibits promising antineoplastic activity against bladder cancer,although its mechanism of action is not fully understood. Therefore, the aim of this study was to inves-tigate the effects of AITC activity on bladder cancer cell lines carrying a wild type (wt; RT4) or mutated(T24) TP53 gene. Morphological changes, cell cycle kinetics and CDK1, SMAD4, BAX, BCL2, ANLN and S100Pgene expression were evaluated. In both cell lines, treatment with AITC inhibited cell proliferation (at62.5, 72.5, 82.5 and 92.5 _M AITC) and induced morphological changes, including scattered and elon-gated cells and cellular debris. Gene expression profiles revealed increased S100P and BAX and decreasedBCL2 expression in RT4 cells following AITC treatment. T24 cells displayed increased BCL2, BAX and ANLNand decreased S100P expression. No changes in SMAD4 and CDK1 expression were observed in either cellline. In conclusion, AITC inhibits cell proliferation independent of TP53 status. However, the mechanismof action of AITC differed in the two cell lines; in RT4 cells, it mainly acted via the classical BAX/BCL2 path-way, while in T24 cells, AITC modulated the activities of ANLN (related to cytokinesis) and S100P. Thesedata confirm the role of AITC as a potential antiproliferative compound that modulates gene expressionaccording to the tumor cell TP53 genotype.
