Figure 7From: Epigenetic mechanisms involved in differential MDR1mRNA expression between gastric and colon cancer cell lines and rationales for clinical chemotherapy Activation of MDR1 mRNA expression by 5AC and/or TSA in various colon cancer cell lines. RT-PCR assay after treating the cells with 5AC and/or TSA using the same method described in Figure 6. The MDR1/β-actin ratio obtained through 35-cycle PCR after TSA in combination with 5AC, and alone in SNU-C5 and HT-29 expressing no MDR1 mRNA, respectively, was omitted in the histogram.Back to article page
