Abstract

Background: Pancreatic cancer is a malignant tumor with high mortality. Acidic nuclear phosphoprotein 32 family member E (ANP32E), a specific H2A.Z chaperone, has been shown to contribute to breast cancer development. However, the significance of ANP32E in pancreatic cancer is poorly understood. This study aimed to investigate the role of ANP32E in pancreatic cancer. Methods: The expression of ANP32E in 179 pancreatic cancer tissues and 171 normal tissues, and the correlation between ANP32E expression and patients’ survival were analyzed from the TCGA database. ANP32E was over-expressed and silenced using lentivirus. siRNA was used to knock down β-catenin. CCK8, colony formation, cell cycle and transwell experiments were performed to determine cell proliferation and migration. qRT-PCR and Western blot were conducted to detect mRNA and protein expression. Results: ANP32E was up-regulated in pancreatic cancer tissues and cells. Up-regulation of ANP32E predicted poor prognosis in pancreatic cancer patients. Lentivirus-mediated knockdown of ANP32E suppressed the proliferation, colony growth and migration of PANC1 and MIA cells. By contrast, ANP32E over-expression promoted the proliferation and migration of both cells. In addition, ANP32E accelerated the cell cycle progression in PANC1 and MIA cells. Molecular experiments showed that ANP32E activated β-catenin/cyclin D1 signaling. Silencing of β-catenin reduced cell proliferation and migration in ANP32E over-expressed cells. Conclusion: Our results propose that ANP32E functions as an oncogene in pancreatic cancer via activating β-catenin.
