Fig. 4. Effect of AK-Ex on apoptosis in HepG2 and HepaRG cells.
(A) HepG2 and (B) HepaRG cells were treated with AK-Ex and/or AAP, as described in Fig. 3. The number of apoptotic cells was assayed by using a cell death detection ELISAPLUS assay kit. Each bar represents mean ± SEM values (n = 4). Means without a common letter differ significantly, P < 0.05.
