Next, we evaluated the expression patterns of ShcA isoforms as well as Ras and TrkB in all characterized tumors represented by the following groups: choroid plexus tumors, diffuse astrocytic and oligodendroglial tumors, embryonal tumors, ependymal tumors, and other astrocytic tumors (see Figure 10 and Supplementary Table S1). This evidence concerns the gene NTRK2 and embryonal neoplasm.
