Fig 1: Suppression effect of magnolol on the invasion and migration ability of GBM cells. (A) The transwell invasion pattern and quantification data after 0, 12.5, 25 µM magnolol, 10 µM Rottlerin (PKCd inhibitor) and 5 µM WP1066 (STAT3 inhibitor) treatment for 48 h in GBM8401 cells. (B) The wound healing pattern and quantification data in GBM8401 cells after various treatments as presented. (C–E) The Western blotting pattern and quantification results of MMP and uPA after magnolol treatment in GBM8401 cells. Full Western blotting images have been provided in supplementary material (Material S1). (* p < 0.05, ** p < 0.01 vs. 0 µM magnolol).
