Abstract: BACKGROUND: The miR-212 was among the top differentially expressed miRNAs in pancreatic
ductal adenocarcinoma (PDAC). OBJECTIVE: The aim of this study was to investigate the expression of miR-212 in PDAC
and evaluate its correlation with major clinicopathologic features and
patients' survival. METHODS: Fluorescence in situ hybridization (FISH) was adopted to examine miRNA
expression in 45 pancreatic cancer and 20 normal pancreatic tissues. The
relationship of miR-212 expression with clinicopathologic parameters and
clinical outcome was evaluated. RESULTS: miR-212 was confirmed to have significantly higher expression in PDAC
compared with normal pancreatic tissues (51.1% vs 10%, p< 0.01). High
expression of miR-212 was significantly associated with tumor size (p =
0.048) and tumor stage (p = 0.023). Moreover, in univariant analysis,
patients with high expression of miR-212 demonstrate significantly poorer
overall survival (p= 0.02). CONCLUSIONS: High expression of miR-212 in PDAC is associated with shorter overall
survival. It may be not only a potential prognostic marker, but also a
possible therapeutic target in PDAC.
