Scattered plot analyses of the expression levels of FABP7 and EGFR genes. The abundance of mRNA for both genes obtained by microarrays was presented on a log2 base. A strong positive correlation of FABP7 and EGFR expression was seen in a set of 34 GBM specimens (A, p = 0.016), which was validated by a public microarray dataset using 28 GBM specimens (B, p = 0.03).
