EIF4E and central nervous system cancer: According to the findings (Fig. 9A and E), the EIF4E and NCBP2 expression levels were considerably higher in the lower-grade glioma tissues in comparison to that in the healthy brain tissues (p < 0.05); while EIF4E2, EIF4E3, and NCBP1 expression levels in the lower-grade glioma tissues were not statistically different from normal brain tissues (Fig. 9B–D).
