ANTXR2 and synovial sarcoma: In a separate analysis of the different histological subtypes, the median expressions of the CMG2 mRNA in liposarcoma, fibrosarcoma, rhabdomyosarcoma, synovial sarcoma, and neuronal sarcoma were relatively similar (0.01–0.015 fg/fg HPRT), while the median CMG2 mRNA expression in leiomyosarcoma and NOS (not other specified) was slightly, but not significantly, increased (0.032 fg/fg HPRT and 0.026 fg/fg HPRT, respectively, see Figure 1a).
