Grailsine-Al-glycoside triggered significant apoptosis in A549, MCF-7, and Hela cells. Cells treated with different concentration of Grailsine-Al-glycoside for 36 hrs before stained with propidium iodide and underwent flow cytometry analysis. The apoptotic cells were measured by sub-G1 population. Grailsine-Al-glycoside induced over 2 fold increase of apoptosis in A549 (A), Hela (B), and MCF-7 (D) cells but moderate increase in HepG2 cells (C).
