Given the AR’s central role in PC growth and survival, and deep mechanistic understanding of that malignancy20–23, we performed a gene expression analysis comparing 22 DSRCT samples to 12 PC samples and a group of other diverse sarcoma subtypes, including 7 chondrosarcomas, 7 well-differentiated liposarcomas, 10 dedifferentiated liposarcoma, and 47 osteosarcoma samples, which served as negative controls. The gene discussed is AR; the disease is liposarcoma.
