Hmgb1-IL-23-IL-17-IL-6-Stat3 Axis Promotes Tumor Growth in Murine Models of Melanoma

Figure 5

IL-17 promotes Stat3 activation. (a) Indicating p-Stat3 protein levels (analyzed by Western blot) in B16 tumor tissues from WT, WT + anti-γ δ TCR, and IL-17^−/− groups (𝑛=5). (b) Tumor growth in B16 tumor-bearing wild-type mice injected by oral gavage with WP1066 at 40 mg/kg once per day (5 days on and 2 days off) (𝑛=5). (c) The number of PCNA⁺ cells in tumor tissues from B16-F10 tumor-bearing wild-type mice 2 weeks after inoculation (𝑛=5). (d) CD11b⁺Gr-1⁺ MDSCs in tumor samples of B16-F10 tumor-bearing wild-type mice (𝑛=5). (e) The number of blood vessels in tumor tissues from B16-F10 tumor-bearing wild-type mice (𝑛=5). The data show means ± SEM of tumor size and are representative of three independent experiments. ^∗𝑃<0.05.
