As shown in Figure 9, there was positive correlation between the miR-148a levels in 10 freshly collected glioblastoma samples with MMP9 (r = 0.674, P < 0.001) and VEGF mRNA levels (r = 0.748, P < 0.001), the DNA-binding activity of NF-κB (r = 0.895, P < 0.001), and p-Smad3 expression (r = 0.754, P = 0.001). Here, MMP9 is linked to glioblastoma.
