Figure 3From: Attenuation of PTEN increases p21 stability and cytosolic localization in kidney cancer cells: a potential mechanism of apoptosis resistancePTEN-knockdown reduces sensitivity to cisplatin-induced apoptosis. ACHN cells stably transfected with PTEN-shRNA (black bars) or pSuper empty vector control (gray bars) were incubated with the indicated concentrations of cisplatin for 24 h. Caspase-3 activity was measured as an indicator of apoptosis as described in Materials and Methods.Back to article page
