Caspase-independent cell death pathway activation investigated by fluorescence microscopy. Double immunostaining for mitochondria (green fluorescence) and apoptosis-inducing factor (AIF, red fluorescence) in the controls, differently treated U251 cells, i.e., after 48-h continuous treatment (CT) with 40 μM cis-dichlorodiammineplatinum (CDDP) or 10 μM (OC-6-44)-acetatodiamminedichlorido(2-(2-propynyl)octanoato)platinum(IV) [Pt(IV)Ac-POA], and in the recovered (REC) conditions. DNA counterstaining with Hoechst 33258 (blue fluorescence). Scale bar, 20 μm.
