From: Antiproliferative effect of exemestane in lung cancer cells
The effect of a) exemestane and b) testosterone on aromatase activity of H23 and A549 cells. H23 and A549 cells were treated with 50 μM and 20 μM exemestane, respectively and both cell lines were treated with 1 μM testosterone. At the time points of 15 min, 6, 8, 12, 24 and 48 h, samples were analysed as described in Methods. *P < 0.05, ** P < 0.01 and *** P < 0.001.
