Eukaryotic translation initiation factors (eIFs) constitute a new class of
therapeutic cancer targets. EIF3b is the major scaffold protein of eIF3 (the
largest core of eIFs). We sought to define the role played by and the mechanism
of action of eIF3b in patients with clear cell renal cell carcinoma (ccRCC). We
found that high-level eIF3b expression in tumors was not only associated with an
aggressive tumor phenotype, but was also independently prognostic for patients
with ccRCC. Knockdown of eIF3b impaired the action of the Akt pathway, thus
inhibiting cell proliferation by disrupting the cell cycle and triggering
apoptosis. Furthermore, the epithelial-to-mesenchymal transition was impaired
after eIF3b depletion, via suppression of cell migration and invasion.
Additionally, eIF3b knockdown significantly inhibited the growth of subcutaneous
xenografts in mice. Together, these data show that eIF3b is both a promising
prognostic biomarker and a potential therapeutic target for patients with ccRCC.
