And there was no significant difference in expression levels between LMS and synovial sarcoma (n = 16), myxoid liposarcoma (n = 19), dedifferentiated liposarcoma (n = 15), myxofibrosarcoma (n = 15), fibrosarcoma (n = 4), malignant peripheral nerve sheath tumor (MPNST, n = 3) and malignant fibrous histiocytoma (MFH, n = 21).The data set GSE71121 (Fig. 5B) revealed that the expression level of EZH2 mRNA in LMS (n = 90) was higher than that in differentiated liposarcoma (n = 44), undifferentiated sarcoma (n = 88) and other unclassified sarcoma (n = 45) (p < 0.05). This evidence concerns the gene EZH2 and undifferentiated pleomorphic sarcoma.
