Translation Initiation Factor-2S2 (eIF2S2) Contributes to Cervical Carcinogenesis by Inhibiting the TGF-β/SMAD4 Signaling Pathway.

ABSTRACT: The deregulation of protein translational machinery and the oncogenic role of several translation initiation factors have been extensively investigated. This study aimed to investigate the role of eukaryotic translation initiation factor 2S2 (eIF2S2, also known as eIF2β) in cervical carcinogenesis. Immunohistochemical analysis of human cervical carcinoma tissues revealed a stage-specific increase in eIF2S2 expression. The knockdown of eIF2S2 in human cervical cancer (SiHa) cells significantly reduced growth and migration properties, whereas its overexpression demonstrated the opposite effect. Immunoprecipitation and Bimolecular fluorescence complementation (BiFC) assay confirmed the previous photo array finding of the interaction between eIF2S2 and SMAD4 to understand the tumorigenic mecha
