However, the relationship between EGFL7 and the prognosis of pancreatic cancer（PC） remains unclear. The present study was undertaken to investigate the role of EGFL7 in the prognosis of PC.METHODS： The expression of EGFL7 in nine PC cell lines was first determined by Western blotting analysis. Tissue microarray-based immunohistochemical staining was performed in paired formalin-fixed paraffin-embedded tumor and non-tumor samples from 83 patients with PC. Finally,correlations between EGFL7 expression and clinicopathological variables as well as overall survival were evaluated.RESULTS： EGFL7 was widely expressed in all PC cell lines tested.EGFL7 expression in tumor tissues was significantly higher than that in non-tumor tissues（P0.040）. In addition, univariate analysis revealed that high EGFL7 expression in tumor tissues was significantly associated with poor overall survival,accompanied by several conventional clinicopathological variables, such as gender, histological grade and lymph node metastasis. In a multivariate Cox regression test, EGFL7 expression was identified as an independent marker for longterm outcome of PC.CONCLUSION： Our data showed that EGFL7 is extensively expressed in PC and that EGFL7 is associated with poor prognosis.展开更多

Recently, there has been a significant increase in research directed towards identifying potential biomarkers that can be used to diagnose and provide prognostic information for pancreatic cancer. These markers can be used clinically to optimize and personalize therapy for individual patients. In this review, we focused on 3 biomarkers involved in the DNA damage response pathway and the necroptosis pathway: Chromodomainhelicase-DNA binding protein 5, chromodomain-helicaseDNA binding protein 7, and mixed lineage kinase domain-like protein. The aim of this article is to review present literature provided for these biomarkers and current studies in which their effectiveness as prognostic biomarkers are analyzed in order to determine their future use as biomarkers in clinical medicine. Based on the data presented, these biomarkers warrant further investigation,and should be validated in future studies.展开更多
