Barrett’s esophagus is a pro-oncogenic lesion in the proximal gastrointestinal tract, but with a distal colon-like morphology. Here the authors report that the distal HOX gene HOXA13 is expressed in Barrett’s esophagus and in single cells of the physiological esophagus, and may underlie the phenotypic aspects of metaplasia and increase proliferation.
