Moreover, we confirmed our RNA-Seq results in a wider case series of 50 UPS and 25 MFS patients using the Sarcoma (TCGA, PanCancer Atlas) database and in a case series of 44 UPS and 17 MFS patients using the Adult Soft Tissue Sarcomas (TCGA, Cell 2017) database for MMP13, WNT7B, AKR1C2, AKR1C3, BMP7, AND SGCG genes. This evidence concerns the gene MMP13 and undifferentiated pleomorphic sarcoma.
