MYOD1 and soft tissue sarcoma: Of the highly expressed myogenic precursor and stemness-related genes, CDH15 (Figure 8d) was identified as a significant (p < 0.05) predictor of poor prognosis in soft-tissue sarcomas along with MYOD1 (Figure 8e) and SOX4 (Figure 8f), which, however, did not reach the level of statistical significance (p = 0.053 and p = 0.054, respectively).
