Additionally, a higher caspase-9 activity, compared to the control, was observed in the endometrial cancer cell cultures exposed to cisplatin (2.5 μM of the drug = 133.58%; p = 0.0000; 5 μM = 140.55%; p = 0.0000; 10 μM = 147.09%; p = 0.0000). The gene discussed is CASP9; the disease is endometrial cancer.
