From: Antiproliferative effect of exemestane in lung cancer cells
The effect of exemestane on mRNA levels of aromatase in H23 and A549 cells. H23 and A549 cells were treated with 50 μM and 20 μM exemestane respectively and 48 h later, aromatase mRNA levels were studied with real time RT-PCR. Results are expressed as relative expression and normalized to untreated cells. Asterisks denote a statistically significant difference (unpaired t-test) compared to untreated cells. * P < 0.05.
