Effects of RAR agonists on the growth of Luminal and Basal breast cancer cell linesThe indicated Luminal and Basal cell lines were challenged with increasing concentrations of ATRA, the RARα agonist, AM580, the RARβ agonist, UVI2003, and the RARγ agonist, BMS961, for 6 days. The complement of RAR-variant transcripts expressed in each cell line is shown in the left bar graphs (mean ± SD of two replicate measurements). The growth curves (sulforhodamine assay) of the cell lines are illustrated by the right linear plots. The results are expressed in % values relative to the corresponding control dishes treated with vehicle alone (right graphs). Each result is the mean ± SD of five replicate wells. ATRA sc = ATRA score.
