1 Characterization of p53 wild-type and null isogenic colorectal cancer cell lines resistant to 5-fluorouracil, oxaliplatin, and irinotecan. Oxaliplatin tumor protein p53 Homo sapiens
2 In addition, we found that resistance to 5-FU and oxaliplatin was higher in parental p53(-/-) cells compared with parental p53(+/+) cells, with an approximately 5-fold increase in IC(50 (72 h)) for each drug. Oxaliplatin tumor protein p53 Homo sapiens
3 In addition, we found that resistance to 5-FU and oxaliplatin was higher in parental p53(-/-) cells compared with parental p53(+/+) cells, with an approximately 5-fold increase in IC(50 (72 h)) for each drug. Oxaliplatin tumor protein p53 Homo sapiens
4 Furthermore, apoptosis after treatment with 5-FU and oxaliplatin, but not CPT-11, was significantly reduced in parental p53(-/-) cells compared with parental p53(+/+) cells. Oxaliplatin tumor protein p53 Homo sapiens
5 Furthermore, apoptosis after treatment with 5-FU and oxaliplatin, but not CPT-11, was significantly reduced in parental p53(-/-) cells compared with parental p53(+/+) cells. Oxaliplatin tumor protein p53 Homo sapiens
6 These data suggest that p53 may be an important determinant of sensitivity to 5-FU and oxaliplatin but not CPT-11. Oxaliplatin tumor protein p53 Homo sapiens
