Radiotherapy blocked the growth of schwannoma cells (Supplementary Fig. 14a, b), and qPCR assessment of genes distinguishing molecular groups of human schwannomas (Fig. 1) showed radiotherapy induced schwannoma cell expression of inflammatory apolipoproteins43,44, immediate early genes that drive cell fate decisions45, and SOX6, an inhibitor of oligodendrocyte cell differentiation46 (Supplementary Fig. 14c). The gene discussed is SOX6; the disease is schwannoma.
