The results indicated that PPFIBP1 protein levels in GBM tissues (14/23, 61%) were significantly higher than that in LGG (6/24, 25%) (P = 0.041, Fig. 1A), and higher in invasive LGG tissues (3/10, 30%) than in noninvasive LGG tissues (3/14, 21%), although not statistically significant (Fig. 1B). Here, PPFIBP1 is linked to glioblastoma.
