NF-kappaB promotes epithelial-mesenchymal transition, migration and invasion of pancreatic carcinoma cells.

The transcription factor NF-kappaB is constitutively active in pancreatic adenocarcinoma. Here we explore the contribution of NF-kappaB to the malignant phenotype of pancreatic cancer cells in addition to its anti-apoptotic role. Block of NF-kappaB signalling by non-destructible IkappaBalpha rendered cells resistant to TGF-beta-induced epithelial-mesenchymal transition (EMT).
