Solasodine induces apoptosis in colorectal cancer cells. (a) Three types of colorectal cancer cells were treated with solasodine and then analyzed by annexin V/propidium iodide (AV/PI) staining. Lower left (LL) quadrants, living cells (AV negative/PI negative). Lower right (LR) quadrants, early apoptotic cells (AV positive/PI negative). Upper right (UR) quadrants, late apoptotic cells (AV positive/PI positive). Upper left (UL) quadrants, necrotic cells (AV negative/PI positive). (b) Variations in nuclear morphology were examined by Hoechst 33258 staining and captured by fluorescence microscopy. 5‐Fu, 5‐fluorouracil.
