Fig. 1From: Pregnane X receptor is associated with unfavorable survival and induces chemotherapeutic resistance by transcriptional activating multidrug resistance-related protein 3 in colorectal cancerPXR over-expression decreases L-OHP levels in tumor cells. The transport and uptake of L-OHP in tumor cells were assessed by mass cytometry. L-OHP content in PXR or PXR + RXRA stably transfected tumor cells was reduced compared with that in empty vector stably transfected tumor cells on average in both HCT116 (a) and LOVO (b) cells. Tumour cells were treated for 2 h with 20 mmol/L oxaliplatin. P + R, PXR + RXRA. The unit shown is Pt atoms/cellBack to article page
