Description…

RUNX3 is a member of the runt domain-containing family of transcription factors. A heterodimer of this protein and a beta subunit forms a complex that binds to the core DNA sequence 5'-PYGPYGGT-3' found in a number of enhancers and promoters, and can either activate or suppress transcription. It also interacts with other transcription factors. It functions as a tumor suppressor, and the gene is frequently deleted or transcriptionally silenced in cancer. Multiple transcript variants encoding different isoforms have been found for this gene.

Overview

Esophageal adenocarcinoma risk in Barrett's esophagus is increased 30- to 125- fold versus the general population. Among all Barrett's esophagus patients neoplastic progression occurs only once per 200 patient-years. Molecular markers (individual or in panel) would be useful to risk-stratify patients for more efficient surveillance endoscopy and to improve the early detection of progression.

Performance Comment

p16, RUNX3, and TMEFF2 (HPP1) display increasing methylation frequencies in Barrett's esophagus versus esophageal adenocarcinoma. These markers are being further investigated for potential utility in screening Barrett's patients likely to develop esophageal adenocarcinoma.

Barrett's Esophagus Methylation Profiles

We propose a nested case-control study of biomarkers in the setting of BE. By bringing together research institutions with large populations of patients with BE, we will perform a multi-center study of FISH and hypermethylation markers as possible prognostic factors in BE. The centers will select from their cohorts who have progressed to HGD or to adenocarcinoma of the esophagus ("progressors"), and who also donated samples prior to the development of cancer, when their histology was felt to be benign. These subjects will be compared to individuals who have been under endoscopic surveillance, but who have not progressed to HGD or EAC ("non-progressors"). Using this approach, we hope to identify promising markers for risk stratification in BE. We expect to be able to make successful application for a prospective study of markers identified in this case-control study.
