(Q) H&E staining of liver tissues treated with PBS, Bindarit, IL-6 Abs, or Bindarit plus IL-6 Abs in Tet2 WT -CCl 4 and Tet2 ΔMye -CCl 4 mice ( n = 4 for each group). Data are representative of at least two independent experiments with similar results (A–P). All data are shown as mean ± SD and were analyzed by two-tailed, unpaired Student’s t test (A, C, D, E, K, L, and O) or one-way ANOVA with Tukey’s multiple comparison test (B and J) or two-way ANOVA with Sidak’s multiple comparison test (F–I, M, and N). ****P < 0.0001; ***P < 0.001; **P < 0.01; *P < 0.05; P > 0.05 not significant (ns).
