STAT3 and glioblastoma: Based on the selection of EMT-related genes, expression levels (> 2.0-fold) in GBM-R2I2, Par/STAT3, and R2I2/sh-Scr cells were stronger than those in their counterparts (Figure 2C), and the array results were further corroborated by Q-PCR of GBM-Par and GBM-R2I2 cells (Figure S2A).
