1 Upregulation of CYP2S1 by oxaliplatin is associated with p53 status in colorectal cancer cell lines. Oxaliplatin tumor protein p53 Homo sapiens
2 In the present study, oxaliplatin was found to strongly inhibit the growth of HCT116 cells harboring wild-type p53 but to only weakly inhibit SW480 cells, HT29 cells or p53-/- HCT116 cells, which all lack p53 expression. Oxaliplatin tumor protein p53 Homo sapiens
3 In the present study, oxaliplatin was found to strongly inhibit the growth of HCT116 cells harboring wild-type p53 but to only weakly inhibit SW480 cells, HT29 cells or p53-/- HCT116 cells, which all lack p53 expression. Oxaliplatin tumor protein p53 Homo sapiens
4 In the present study, oxaliplatin was found to strongly inhibit the growth of HCT116 cells harboring wild-type p53 but to only weakly inhibit SW480 cells, HT29 cells or p53-/- HCT116 cells, which all lack p53 expression. Oxaliplatin tumor protein p53 Homo sapiens
5 Administration of oxaliplatin significantly induced p53 accumulation and enhanced expression of CYP2S1 in HCT116 cells with wild-type p53. Oxaliplatin tumor protein p53 Homo sapiens
6 Administration of oxaliplatin significantly induced p53 accumulation and enhanced expression of CYP2S1 in HCT116 cells with wild-type p53. Oxaliplatin tumor protein p53 Homo sapiens
7 Interestingly, enzyme immunoassays, TOPFlash/FOPFlash reporter activity assays and western blotting analysis demonstrated oxaliplatin-mediated downregulation of PGE2 and Wnt/beta-catenin signaling in a manner dependent on p53. Oxaliplatin tumor protein p53 Homo sapiens
8 These results suggest that oxaliplatin exerts its inhibitory effects in human CRC cells via upregulation of CYP2S1 expression in a p53-dependent manner. Oxaliplatin tumor protein p53 Homo sapiens
