In this study, we analyzed STAT3 expression in GBM (glioblastoma multiforme) and LGG (low-grade glioma) tissues from the TCGA microarray database and found that STAT3 expression significantly increased, which was associated with lower overall survival and disease-free survival (Figures 3(a)–3(b)). The gene discussed is STAT3; the disease is glioblastoma.
