SRSF1 and glioblastoma: Most specifically, based on REMBRANDT data, SRSF1 mRNA was significantly upregulated in all glioma grades with respect to normal brain (p-value < 0.0001, ANOVA test) (Figure S1A, Supplementary Materials), while VEGFA was significantly upregulated specifically in GBM (p-value < 0.0001, ANOVA test) (Figure S1B, Supplementary Materials).
