We examined the expression levels of EMT-associated genes in three pairs of cells, i.e., GBM-Par vs. GBM-R2I2, Par/Ctrl vs. Par/STAT3, and R2I2/sh-Scr vs. R2I2/sh-STAT3, through RT2 Profiler PCR arrays to identify potential downstream molecular factors of the STAT3-mediated invasive phenotype. The gene discussed is STAT3; the disease is glioblastoma.
