FIGURE 3: NPM1 translocation under nucleolar stress. Representative images of NPM1 translocation in HeLa cells under various nucleolar stresses, including H₂O₂ (500 mM, 30 min), hypoxia (1% O₂, 1 h), UV irradiation (100 J m^-2), heat-shock (42°C, 30 min), EBSS starvation (6 h) and Act.D (8 nM, 1 h), examined by immunofluorescence with anti-NPM1 antibody. Bar, 5 mm. Image from ref [31].
