Additionally, using the gene expression profiling interactive analysis (GEIPA) portal available through TCGA (http://gepia.cancer-pku.cn/), we found that OS was significantly decreased in soft-tissue sarcomas with high expression of RAD21 or MYC, but not for HEY1, UBR5, RECQL4, or SOX17, making RAD21 and MYC the 2 most likely candidate genes (Figure 5B). This evidence concerns the gene RECQL4 and soft tissue sarcoma.
