Figure 4From: Irinotecan induces steroid and xenobiotic receptor (SXR) signaling to detoxification pathway in colon cancer cellsInduction of irinotecan metabolism genes after CPT-11 and SN-38 treatment. LS180 and HepG2 cells were treated with 1 μg/ml CPT-11 or 10 ng/ml SN-38 for 24 h and quantitative RT-PCR were performed on irinotecan metabolism genes. Fold inductions were calculated relative to the mean expression of GAPDH and experiments were performed in triplicate. (a ND for not detected).Back to article page
