Fig. S9 — Functional role of PA28γ on tumor growth. PA28γ-si could inhibit PA28γ expression in an OSCC xenografts model; angiogenesis in tumors was detected by CD34 staining. The average number of microvessels per vascular hot spot (mean ± SD) was significantly lower in PA28γ-si group tissues compared with those in the two control groups; Percentages of PCNA-positive nuclei (mean ± SD) in PA28γ-si group were significantly lower than those in the two control groups; Apoptosis was assessed by TUNEL assay. The scale bar represents 100 μm. (*P < 0.05).
