The PRKD1 promoter is a target of the KRas-NF-κB pathway in pancreatic cancer
Increased expression of PRKD1 and its gene product protein kinase D1 (PKD1) are linked to oncogenic signaling in pancreatic ductal adenocarcinoma, but a direct functional relationship to oncogenic KRas has not been established so far. We here describe the PRKD1 gene promoter as a target for oncogeni...

description | Increased expression of PRKD1 and its gene product protein kinase D1 (PKD1) are linked to oncogenic signaling in pancreatic ductal adenocarcinoma, but a direct functional relationship to oncogenic KRas has not been established so far. We here describe the PRKD1 gene promoter as a target for oncogenic KRas signaling. We demonstrate that KRas-induced activation of the canonical NF-κB pathway is one mechanism of how PRKD1 expression is increased and identify the binding sites for NF-κB in the PRKD1 promoter. Altogether, these results describe a novel mechanism governing PRKD1 gene expression in PDA and provide a functional link between oncogenic KRas, NF-κB and expression of PRKD1. |
