1 Mutant p53 stimulates chemoresistance of pancreatic adenocarcinoma cells to gemcitabine. gemcitabine tumor protein p53 Homo sapiens
2 The purpose of this study was to assess the relevance of the p53 status on the PDAC cells response to the standard drug gemcitabine. gemcitabine tumor protein p53 Homo sapiens
3 We showed that gemcitabine stabilized mutant p53 protein in the nuclei and induced chemoresistance, concurrent with the mutant p53-dependent expression of Cdk1 and CCNB1 genes, resulting in a hyperproliferation effect. gemcitabine tumor protein p53 Homo sapiens
4 We showed that gemcitabine stabilized mutant p53 protein in the nuclei and induced chemoresistance, concurrent with the mutant p53-dependent expression of Cdk1 and CCNB1 genes, resulting in a hyperproliferation effect. gemcitabine tumor protein p53 Homo sapiens
5 Despite the adverse activation of mutant p53 by gemcitabine, simultaneous treatment of PDAC cells with gemcitabine and p53-reactivating molecules (CP-31398 and RITA) reduced growth rate and induced apoptosis. gemcitabine tumor protein p53 Homo sapiens
6 Despite the adverse activation of mutant p53 by gemcitabine, simultaneous treatment of PDAC cells with gemcitabine and p53-reactivating molecules (CP-31398 and RITA) reduced growth rate and induced apoptosis. gemcitabine tumor protein p53 Homo sapiens
7 Together, our results show that gemcitabine aberrantly stimulates mutant p53 activity in PDAC cells identifying key processes with potential for therapeutic targeting. gemcitabine tumor protein p53 Homo sapiens
