Figure 1: Induction of apoptosis by ethanol extracts of Hizikia fusiforme (EHF) in PC3 cells. (A) Cell viability was measured by MTT assay. (B) DNA fragmentation. (C) The nuclear morphological changes were observed using DAPI staining, and then photographed under a fluorescence microscope. (D) The percentages of apoptotic cells are expressed (n=3). *P<0.05 and ***P<0.001 compared to untreated cells.
