Abstract
Aurora-2 is a serine threonine kinase that associates with the centrosome. Overexpression or ectopic expression of Aurora-2 appears to alter centrosome number and function and has been implicated in a variety of human cancers. In this work, we demonstrate that Aurora-2 is both amplified and overexpressed in human pancreatic cancer cell lines, with a 2-5-fold increase in gene copy number and a 3-4-fold increase in protein levels compared with controls. Aurora-2 is also amplified and overexpressed in pancreatic cancers taken directly from patients. An immunohistochemistry of tissues taken directly from patients demonstrated an overexpression of Aurora-2 in 26 of 28 pancreatic cancers compared with 18 normal pancreas samples. Antisense nucleotides specifically targeted at Aurora-2 arrest the cell cycle in pancreatic cancer cells, indicating the potential of Aurora-2 as a therapeutic target in pancreatic cancer.Entities:
