ALDH1A3 and glioblastoma: In our analysis, we put special emphasis on probing the potential correlation between the expression of two main mTOR signaling genes, namely EIF4EBP1 (gene encoding 4EBP1) and RPS6 (gene encoding S6), and one EMT marker, namely ZEB1 as well as one mesenchymal marker, namely ALDH1A3, a recently identified marker for mesenchymal transformation in GBM [28].
