As shown in Figure 2, the expression levels of HP1-β (CBX1) were upregulated in the Detwiller sarcoma database; the fold-changes for the expression of these genes in synovial sarcoma, pleomorphic liposarcoma, leiomyosarcoma, fibrosarcoma, and malignant fibrous histiocytoma were 4.180, 2.460, 3.155, 4.010, and 3.294, respectively. This evidence concerns the gene TFF3 and synovial sarcoma.
