Figure Lengend Snippet: Fig. 6 Suppression of CTLs by CD11b+ MDSCs is responsible for the acceleration of tumor progression by Regnase-1 downregulation. A-D Evaluation of phenotypes of orthotopic syngeneic tumors of WT or Regnase-1 KO murine pancreatic cancer cells. Representative macro images of pancreatic tumors (A). Relative mRNA levels of Cd8a, Ifng, Fasl, and Gzmb (B) (N = 6 per group). Representative images of HE (C, left panel) and CD8a immunostaining (C, right panel) and the number of CD8-positive cells (C, right) (N = 6 per group). Dot plots of CD3+CD8+ cells evaluated by flow cytometry (D, left) and the proportion of CD8 + cells among CD45+ cells (D, right) (N = 3 per group). E–H Evaluation of phenotypes of orthotopic syngeneic tumors of WT or Regnase-1-KO murine pancreatic cancer cells with or without depletion of CD8+ cells upon anti-CD8a antibody or IgG treatment. Experimental schematic (E). Dot plots of CD3+ and CD8.+ cells in WT or Regnase-1-KO syngeneic tumors upon anti-CD8a antibody or IgG treatment evaluated by flow cytometry (F). Tumor weights (G) (N = 6 per group). The relative mRNA levels of Cd8a, Ifng, Fasl, and Gzmb (H) (N = 6 per group). Student’s t test was used to evaluate differences between 2 groups. One-way ANOVA with Tukey’s post hoc test was used to compare differences among 4 groups. *P < 0.05, scale bars: 100 μm (insets)
