In vivo antitumor evaluation. (A) Tumor growth curves of different groups after treatment with PBS, pGO, pGO-Pt/DOX, and Pt/DOX mixture, respectively. Bars, mean ± SD (n = 6). (B) Representative photos, H&E staining and immunohistochemical staining Ki-67 of tumor tissues get from mice after various treatments. Black arrows represent the huge cell nuclei. Yellow arrows represent the Ki-67 active cells. Black Scale bar: 5 mm; Red Scale bar: 50 μm. (C) Quantitative analysis the percentage of Ki-67 active cells in tumors. Bars, mean ± SD (n = 6). *p < 0.05.
