Cells in c, d were stained with acridine orange and propidium iodide. e Bar chart analysis of the percentage of viable, apoptotic and late apoptotic/necrotic of control and DK1 treated MCF-7 cells via fluorescent microscopic count of 200 cells. The experiment was done in triplicate and the data are expressed as mean ± SE with (*p < 0.05)
