Esophageal epithelium of 12 weeks old mice (WT, Nrf2-/-) on C57BL background with or without gastroesophageal reflux for 4 weeks.

Transcriptional profiling of adult esophageal epithelium comparing wild-type mice with Nrf2-/- mice with or without gastroesophageal reflux for 4 weeks. Goal was to determine the role of Nrf2 on the barrier function of mouse esophageal epithelium. Two-class comparisons. Wild-type/without reflux vs. Nrf2-/-/without reflux; Wild-type/gastric reflux vs. Nrf2-/-/gastric reflux; Wild-type/duodenal reflux vs. Nrf2-/-/duodenal reflux; Wild-type/mixed reflux vs. Nrf2-/-/mixed reflux. Biological replicates: 3 replicates for each group.
