(a–h) Flow cytometry charts show that DHA triggered apoptosis in human endometrial cancer cells. Ishikawa cells were treated with (a) vehicle for 12 hours, (b) vehicle for 24 hours, (c) 20 μM cisplatin for 12 hours, (d) 20 μM cisplatin for 24 hours, (e) 40 μM DHA for 12 hours, (f) 40 μM DHA for 24 hours, (g) 40 μM DHA and 20 μM cisplatin for 12 hours, or (h) 40 μM DHA and 20 μM cisplatin for 24 hours. (i) Chart shows significantly more cell apoptosis and/or necrosis after treatment (bars indicate mean ± standard deviation from three independent experiments). *p < 0.05 was statistically significant when compared to control cells.
