Research Abstract

We analyzed over 100 surgical tissues of pancreatic cancer by using frozen sections. Several MicroRNA(miRNA) were identified as prognostic markers. Furthermore, we detected that precursor of miR-17-5p and that of miR-10b enhanced proliferation and invasion of pancreatic cancer cells. Meanwhile, we detected that precursor of miR-200c suppressed invasion of pancreatic cancer cells.
