Figure 4. PPI sub-networks. (a–c) indicate the 3 PPI sub-networks constructed by the most significantly upregulated DEGs. (d) shows the PPI sub-network constructed by the downregulated DEGs. Node size stands for the connectivity degree. Blue and red colors indicate downregulated and upregulated genes, respectively. Color depth stands for fold change size. Edge thickness stands for combined score

Figure 7. Immunohistochemical evaluation of CCR family protein expression in cancer and adjacent tissues. CCR2 in leiomyosarcoma (a) and synovial sarcoma (b). CCR4 in leiomyosarcoma (c) and synovial sarcoma (d). CCR5 in leiomyosarcoma (e) and synovial sarcoma (f). The expression of CCRs in tumor tissues is weaker than that in adjacent tissues in the same tumor at 200× magnification. The picture at the bottom right of each slice image is magnified 10 times again
