TGFB1 and central nervous system cancer: We searched for genes involved in 8 common pathways (NF-κB signaling pathway, PI3K/Akt signaling pathway, MAPK signaling pathway, JAK/STAT signaling pathway, TGFβ/SMAD signaling pathway, Wnt/β-catenin signaling pathway, Notch signaling pathway, Hedgehog signaling pathway) in the PathCards database and queried the expression of these genes in glioma by analyzing data from the GEPIA database.
