FBXL7 and glioma: The results of real‐time PCR assay in different grades of glioma tissues (Grades I, II, III and IV according to WHO) and adjacent normal brain tissues (NAT) to determine level of FBXL7 expression reveal significantly up‐regulated FBXL7 expression in glioma tissues all four grades compared with NAT specimens (Figure 1A), which improved progressively as the glioma grades increased (Figure 1A).
