Flow cytometric pattern of SK-OV-3 cells treated with I3C, RE and combination: SK-OV-3 cells without treatment (controls) (A), treatment with 100 µg/ml I3C only (B), 100 µg RE only (C) or treated with a combination of I3C and RE (D), were examined by flow cytometry. Note drastic reduction in G0/G1, G2/M peaks and a dramatic increase in apoptosis (Sub G0) in the treatment groups.
