Sreedharan L, et al. – Aim of this study is to examine the microRNA expression profile in esophageal neosquamous epithelium from patients who had undergone ablation of Barrett’s esophagus. The authors propose that neosquamous mucosa occurring after ablation of Barrett’s esophagus expresses microRNAs that may contribute to decreased barrier function and microRNAs that can be involved in the regulation of survival signaling pathways.
