The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO, GSE4271) database analysis demonstrated that glioma group with high PPFIBP1 expression displayed shorter survival than that with low PPFIBP1 expression, although not statistically significant (P = 0.057, Fig. 1C and Figure S1A). Here, PPFIBP1 is linked to glioma.
