Figure 4From: RNA interference of argininosuccinate synthetase restores sensitivity to recombinant arginine deiminase (rADI) in resistant cancer cellsEffect of ASsiRNA and rADI on cell-cycle phase distribution in HeLa and MCF-7 cells. Cells were seeded in 6-well plates and collected after treating with PBS as control, 1 mU/mL of rADI, or the combination of ASsiRNA transfection and rADI for 4 days, respectively. The cell collections were stained by propidium iodide and the cell-cycle phase distribution examined by flow cytometry.Back to article page
