IL4 and neoplasm: To characterize the mutation status and gene expression levels of the cytokines IL-4 and IL-13, their receptors IL-4Rα, IL-13Rα1/2, and the oncogenes c-Met and EGFR, we performed exome and RNA-seq analysis on DIPG tissues (38 tumor exome, 26 normal exome, 28 tumor RNA, 18 normal RNA, Fig 1,S1 and S2 Figs).
