While results from the small sample size did not reach significance, RT-qPCR showed clear trends towards differential expression for genes with comparable upregulation in both tumor profiles (STIL, PROM1), greater upregulation in the adult profile (BAIAP3, WNT2B) and greater upregulation in the pedB profile (WNT5B, TACR3) (Fig. EV3B). The gene discussed is PROM1; the disease is neoplasm.
