In support of the proposal that alterations in miR-143 and miR-145 expression occur at an early stage in the development of Barrett’s oesophagus, we also observed positive correlations in expression between miR-143 and CK8, and miR-143 and BMP-4, in the oesophageal mucosa from individuals with ulcerative oesophagitis. This evidence concerns the gene BMP4 and Barrett esophagus.
