Figure 6

Modulation of the apoptotic protein biomarkers: PARP (116 kD) and cleaved PARP (85 kD) in HePG2, HCT-116, and MCF-7 cells, was treated dose-dependently with PgE, HaE, and AdE and harvested 24 h after treatments. The immunoblots shown are representative of three independent experiments which all gave similar results where the only representative result was cropped and inserted here. Bars represent the . Single, double, triple, and quadruple asterisks are used for , , , and , respectively, vs. control (DMSO-treated) cells.
