Nek2 is a serine/threonine kinase that has a critical role in mitosis during the cell division process. Despite its importance in centrosome regulation and spindle formation, no direct binders are reported between human pancreatic cancer and Nek2 protein. Our aim in studying Nek2 expression and survival in PDA patients is to determine whether Nek2 is a valuable prognostic factor in PDA tumorigenesis. We found that Nek2 mRNA was elevated in PDA tissues. A high level of expression of Nek2 was significantly correlated with histological differentiation (P=0.042), lymph node metastasis (P=0.003) and tumor stage (P=0.001). Patients with a high Nek2 expression had a significantly worse overall survival (OS) than those patients with low Nek2 expression (P=0.002). Univariate and multivariate analysis revealed that high expression of Nek2 could serve as an independent predictor of poor prognosis. These results indicate that Nek2 could be a promising prognostic molecular marker and an attractive therapeutic target for PDA.
