Figure 5From: Influence of RAR α gene on MDR1 expression and P-glycoprotein function in human leukemic cellsInfluence of retinoic acid (ATRA, 5 μM) on the proliferation of parental and RARα transfected cells. Cells were seeded into 24-well plates (1 × 104 cell per well), ATRA was added at seeding and the cell number was counted at days 1, 3, 5 and 8 after seeding. This figure is representative of 3 separate experiments.Back to article page
