Figure 4From: Activation of caspases and inhibition of ribosome biogenesis mediate antitumor activity of Chijongdan in A549 non-small lung cancer cells Effect of Chijongdan on pro-apoptotic and anti -apoptotic proteins in A549 cells. A549 cells were treated with 25, 50, 100 and 200 μg/ml of Chijongdan for 24 h and Western blotting was performed for pro-apoptotic (A) and anti-apoptotic proteins (B) as shown in Methods.Back to article page
