DUSP26 and glioblastoma: As shown in Figure 1A, the mRNA level of DUSP26 is significantly decreased in the GBM tumor biopsies (N=163) as compared to that in normal brain tissues (N=207), whereas, the DUSP26 mRNA levels in low-grade gliomas (LGG) tumor biopsies (N=518) did not differ from that in normal brain tissue (Figures 1A, B).
