By accessing the online databases R2: Genomics Analysis and Visualization Platform, Serverless, and Logic, we found that both expression levels of IRF1 and MFNG were negatively associated with patients’ metastasis-free survival (MFS) and OS in various sarcomas (Supplementary Figures 6C–E, datasets: GSE42352, GSE21050, and GSE71118). Here, MFNG is linked to sarcoma.
