BDNF and glioma: Based on KEGG analyses, the target genes of hsa-miR-608 were associated with several well-known neuronal signaling pathways, including hsa05214: glioma (p = 1.53E-02), hsa04720: long-term potentiation (p = 5.92E-03), hsa04360: axon guidance (p = 8.38E-04) and hsa04722: neurotrophin signaling pathway (p = 5.87E-04) (Fig. 3A).
