HOXA13 in etiology and oncogenic potential of Barrett's esophagus
AbstractBarrett's esophagus in gastrointestinal reflux patients constitutes a columnar epithelium with distal characteristics, prone to progress to esophageal adenocarcinoma. HOX genes are known mediators of position-dependent morphology. Here we show HOX collinearity in the adult gut while Barrett's esophagus shows high HOXA13 expression in stem cells and their progeny. HOXA13 overexpression appears sufficient to explain both the phenotype (through downregulation of the epidermaldoi:10.1038/s41467-021-23641-8 pmid:34099670 fatcat:egdsub3ck5a7bcrijvdllmtnk4
