Danggui extract inhibits Ang II-induced DNA fragmentation in H9c2 cardiomyoblast cells. (A) Effect of pre-treatment or post-treatment with Danggui extract on Ang II-induced H9c2 cardiomyoblast apoptosis. The blue spot indicates DAPI counterstaining representing the cell number, and the green spot represents the apoptotic cells stained by TUNEL assay. Percentage of apoptotic cells following pre-treatment (B) or post-treatment (C) with Danggui extract in Ang II-induced H9c2 cells. The results are expressed as the mean ± S.E.M. of four independent experiments. #
P < 0.05, ###
P <0.001 in relation to the control. *P < 0.05 in relation to the H9c2 cells treated with Ang II alone.
