Eukaryotic translation initiation factor 4E (eIF4E) is a polypeptide which binds to the 7-methyl guanosine (m7G) 5’ end of the mRNA cap structure and directs its association with ribosomes, initiating eukaryotic protein synthesis. A pleiotropic regulator of translation, eIF4E enables the expression of key genes—such as cyclins, c-myc, and vascular endothelial growth factor (VEGF)— involved in cell proliferation, angiogenesis, and cell survival. Overexpression of eIF4E phosphorylated at serine 209 is associated with tumorigenesis, metastasis, recurrence, and poor overall survival in several cancers, including breast, colon, lung, prostate, breast, lymphoid. As transformed or malignant cells have larger requirements for the expression of pro-survival factors, targeting eIF4E translation and its associated phosphorylation pathways remains an attractive anticancer strategy.
