Abstract
Cytoplasmic polyadenylation element-binding protein 4 (CPEB4), a zinc-finger-containing sequence-specific RNA-binding protein, has been associated with tumor proliferation, invasion, and migration. Expression of CPEB4 and its prognostic significance in human colorectal cancer (CRC) have not been studied. The aim of the present study was to investigate expression of CPEB4 and its prognostic significance in CRC. Expression of CPEB4 in CRC tissues from two independent cohorts was examined by immunohistochemistry. Prognostic significance was analyzed using receiver operating characteristic curve analysis, Kaplan-Meier curves, and Cox regression analysis. High expression of CPEB4 was observed in 14.8 % of CRCs in the training cohort and 12.2 % of CRCs in the validation cohort. High expression of CPEB4 was significantly correlated with the pM classification, TNM stage, and poorer overall survival in both cohorts. Through multivariate Cox regression analysis, high expression of CPEB4 was found to be an independent prognostic biomarker for overall survival in CRC patients. High expression of CPEB4 may be an independent and useful biomarker for predicting the poor survival of patients with CRC.Entities:
