Targeting PERK-ATF4-P21 axis enhances the sensitivity of osteosarcoma HOS cells to Mppα-PDT
Figure 8. p-PERK in vivo levels upon indicated treatments. (A, B) IHC analysis of p-PERK levels in tumor sections (magnification, ×200). (C, D). Fluorescence analysis of p-PERK levels in tumor sections (magnification, ×400). (E, F) Following indicated treatments, tumor tissues were analyzed by western blot for p-PERK levels. Data are shown as mean ± SD of 3 independent experiments. aP < 0.01 vs. control group; bP < 0.01 vs. MPPα-PDT group.
