Core Tip

Core tip: To observe anticancer action of a recombinant adenovirus-mediated p53 (rAd-p53) combined with 5-fluorouracil (5-FU) in human colon cancer with resistance to 5-FU in vivo to investigate the potential and mechanism of rAd-p53 in the reversal of resistance to 5-FU in human colon cancer. Our previous results revealed that exogenous wild-type p53 gene from rAd-p53 can decrease expression of PKC, P-gp and MRP1 in SW480/5-FU (5-FU resistance) and promote apoptosis of tumor cell, which contributes to reversing 5-FU resistance in vivo. 5-FU can increase the expression of exogenous wild-type p53, so 5-FU combined with rAd-p53 has a synergistic anticancer effect for colon cancer of 5-FU resistance in vivo.
