On the cover: Dual color fluorescence microscopy of primary murine podocytes treated with doxorubicin (ADR) or vehicle (Con) illustrating apoptosis, marked by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL, green); Nrf2 antioxidant response, shown by Nrf2 (green) nuclear translocation; and disruption of actin cytoskeleton integrity, characterized by disorganization of filamentous actin (F-actin) stained with rhodamine phalloidin (red). Cells were counterstained with propidium iodide (PI, red) or 4′,6-diamidino-2-phenylindole (DAPI, blue). The arrow indicates Nrf2 nuclear accumulation. The arrowhead indicates nuclear fragmentation in cells without Nrf2 nuclear accumulation following doxorubicin exposure, suggestive of cellular apoptosis.
