In line with our previous results [5], survival analysis revealed that among SOX2, POU5F1 (encoding OCT4), NANOG, PROM1 (encoding CD133), NES (encoding nestin), and ABCG2 genes, only SOX2 expression was significantly (p < 0.05) associated with the survival of sarcoma patients and predicted poor prognosis (Figure S10). The gene discussed is ABCG2; the disease is sarcoma.
