From: Antiproliferative effect of exemestane in lung cancer cells
The effect of exemestane on protein levels of aromatase in H23 and A549 cells. A: H23 and A549 cells were treated with 50 μM and 20 μM exemestane respectively and 48 h later, cells were lysed and analyzed in SDS-PAGE. Actin was used as an internal control. The figure is a representative from at least three independent experiments. B: Quantification of western blot images. The results are expressed as % change of control. Asterisks denote a statistically significant difference (unpaired t-test) compared to control. * P < 0.05.
