Cover: In malignant mesothelioma cells nitroxides targeted to mitochondria by triphenylphosphonium groups, including Mito‐carboxy proxyl (Mito‐CP), induce mitochondrial oxidative stress and impair cell viability. Live cell imaging with GFP targeted to mitochondria shows Mito‐CP induces fragmentation of mitochondria, a process that appears distinct from mitochondrial fission. Shown are individual mesothelioma cells before (right) and after (left) treatment with Mito‐CP. Cells were fixed and stained with DAPI to visualize nuclei (blue) and phalloidin to identify actin stress fibers (red). The green signal represent Mito‐roGFP expressed by transient transfection. See Cunniff et al., page 835–845.
