A Western blot assay of GPX4 and SOCS2 proteins and their relative levels in SK-Hep-1, SK-Hep-1R, HepG2 and HepG2R cells at 2, 4, 8, 24 h after 4 Gy IR or non-IR. B Western blot assay of SLC7A11, GPX4 and SOCS2 proteins in SK-Hep-1, SK-Hep-1R, HepG2 and HepG2R cells at 4 h after 4 Gy IR or non-IR. C, D Western blot assay of SLC7A11, GPX4 and SOCS2 proteins in SK-Hep-1, SK-Hep-1R, HepG2 and HepG2R cells with or without lvSOCS2 transfection at 4 h after 4 Gy IR or non-IR. Representative images (F) and quantification (E) of the relative fluorescence intensity of liperfluo in SK-Hep-1 and HepG2 cells transfected with lvSOCS2 at 4 h after 4 Gy IR or non-IR. Nuclei were stained with Hoechst (x40). Scale bars, 10 μm. *P < 0.05, **P < 0.01 and ***P < 0.001 between indicated groups.
