Figure 1From: Quantitative correlation between promoter methylation and messenger RNA levels of the reduced folate carrier [ 3 H]-MTX uptake in M805 cells and HT1080 cells. Cells were incubated with 1 μM [3H]-MTX and incubations were stopped at indicated time points. For each sample, experiments were performed in duplicates for each time point. Average value and standard error are shown.Back to article page
