(b) Images of primary tumors from mice following a 21-day treatment period. (c) Tumor volume curves after different treatments. (d) Body weight changes after 21-day treatment period. (e) H&E and Ki67 (red) stained after different treatments, scale bar = 100 μm. (f) Corresponding fluorescence intensity of GRP78 and (g) GPX4. (h) Immunofluorescence staining results of GRP78 and GPX4, scale bar = 50 μm. (i) Immunofluorescence staining results of iNOS (red), and immunohistochemical staining results of Arg-1 (yellow), scale bar = 100 μm. (j) The image of CD8 + T cells in the tumor after various treatment, scale bar = 100 nm. (k) The level of CD8 + cells in different treatments. The cytokines secretion of (l) IFN-γ and (m) IL-6 in serum after different treatments. (n) The CLSM of CD56 and CD16, scale bar = 100 nm. (o) The level of NK cells after different treatments.
