Figure 5From: Cisplatin-induced caspase activation mediates PTEN cleavage in ovarian cancer cells: a potential mechanism of chemoresistance Cisplatin treatment in ovarian cancer cells activates caspase family members. Caspases are active in all the cell line tested except cisplatin resistant cell line (A2780-CP). Activated forms of caspases are measured using Western blot assay. GAPDH was used as a loading control.Back to article page
