NF-κB Activation in Esophageal Adenocarcinoma

Abstract

Bile acids and low pH induce NF-kappaB expression in esophageal cell lines. NF-kappaB activation is common in esophageal adenocarcinoma. In patients with Barrett's epithelium and an associated esophageal adenocarcinoma, there is a progressive expression of NF-kappaB through Barrett's tumorigenesis. The absence of NF-kappaB expression in esophageal adenocarcinoma correlates with response to neoadjuvant chemoradiotherapy and may be of value in predicting response to neoadjuvant therapy.
