Abstract

Disrupted protein translation is prevalent in tumours. Eukaryotic translation initiation factors (eIFs) were found to play an important role in various tumours. However, the involvement of eIFs in glioma remains to be elucidated. The present study explored the expression and the role of eIF 3, subunit C (eIF3c) in human glioma. The expression of eIF3c in glioma tissues was evaluated by immunohistochemistry. The impact of eIF3c inhibition on U‑87 MG was explored in vitro and in vivo by lentivirus‑mediated siRNA targeting eIF3c. The results revealed that overexpression of eIF3c was present in glioma tissues. Knockdown of eIF3c significantly impaired cell proliferation and colony formation, further induced cell cycle arrest and apoptosis in the U‑87 MG cell line. Furthermore, tumoursphere formation in the U‑87 MG glioma xenograft model was blocked by eIF3c knockdown. The involvement of eIF3c in the tumorigenesis of glioma was confirmed, suggesting eIF3c may be a promising therapy target in human glioma.
