Background: overexpression of paternally expressed gene-10 (peg10) is known to promote the progression of several carcinomas,however,its role in pancreatic cancer (pc) is unknown. we investigated the expression and function of peg10 in pc. methods: peg10 expression and correlation with pc progression was assessed in cancerous tissues and paired non-cancerous tissues. further,the role of peg10 in pc cell progression and the underlying mechanisms were studied by using small interfering rna (si-rna). results: peg10 expression was significantly higher in cancerous tissues and correlated with pc invasion of vessels and ki-67 expression. si-rna mediated peg10 knockdown resulted in inhibition of proliferation and g0/g1 cell cycle arrest,which was mediated by p21 and p27 upregulation. a decrease in pc cell invasion and migration,mediated by erk/mmp7 pathway,was observed in peg10 knockdown group. further,findings of chip assay suggested that e2f-1 could directly enhance the expression of peg10 through binding to peg10 promoter. conclusions: in conclusion,peg10 was identified as a prognostic biomarker for pc and e2f-1 induced peg10 could promote pc cell proliferation,invasion,and metastasis. © 2017 the author(s).
