Gene Amplifications in Well-Differentiated Pancreatic Neuroendocrine Tumors Inactivate the p53 Pathway

Abstract excerpt

Neuroendocrine tumors (NETs) comprise a group of rare tumors derived from the diffuse neuroendocrine system or islet endocrine cells of the pancreas. The molecular mechanisms underlying NETs are largely unknown. The tumor suppressor p53 plays a critical role in maintaining genomic stability and tumor prevention. The p53 pathway is tightly regulated by a number of proteins, among which MDM2, MDM4, and WIP1 are key...
