Pancreatic adenocarcinoma pathway (WP4263)

Infiltrating ductal adenocarcinoma is the most common malignancy of the pancreas. When most investigators use the term 'pancreatic cancer' they are referring to pancreatic ductal adenocarcinoma (PDA). Normal duct epithelium progresses to infiltrating cancer through a series of histologically defined precursors, Pancreatic Intraepithelial Neoplasia (PanINs: https://pathology.jhu.edu/pancreas/professionals/DuctLesions.php). The overexpression of HER-2/neu (ERBB2) and activating point mutations in the K-ras gene occur early, inactivation of the p16 gene (CDKN2A) at an intermediate stage, and the inactivation of p53, SMAD4, and BRCA2 occur relatively late. Activated K-ras engages multiple effector pathways. Although EGF receptors are conventionally regarded as upstream activators of RAS proteins, they can also act as RAS signal transducers via RAS-induced autocrine activation of the EGFR family ligands. Moreover, PDA shows extensive genomic instability and aneuploidy. Telomere attrition and mutations in p53 and BRCA2 are likely to contribute to these phenotypes. Inactivation of the SMAD4 tumor suppressor gene leads to loss of the inhibitory influence of the transforming growth factor-beta signaling pathway. The progression of disease and associated mutations is defined based on the arrow at the top, from left to right.
