title: The effect of the glutamine analog, AT-125, on the cell cycle of MCF-7 and BT-20 human breast carcinoma cells using DNA flow cytometry.
abstract: It was found by DNA flow cytometry that AT-125 preferentially inhibited the cell cycle progression in G1-phase of BT-20 more so than MCF-7 breast carcinoma cells in vitro and that cells washed free of the drug now possessed S-phase DNA content. It was also found that gamma-glutamyl transpeptidase levels were more than 2 times higher in BT-20 than in MCF-7 cells.
