Figure 4. The protective effect of F. suspensa bioactives against UVA-induced apoptosis and cell-cycle arrest. (A) After exposure to UVA for 24h, untreated cells or cells pretreated as described in were irradiated, followed by staining with annexin-V/PI and quantification of apoptosis by FACS. (B) To assess cell-cycle arrest, the cells were stained with PI staining reagent, and the percentages of cells in each phase of the cell cycle were measured by FACS
