Effects of exendin-4 in Brunner's glands of male GLP-1R-/- and wild-type control mice

To gain insight into the biological functions of the highly expressed GLP-1R in Brunners glands, transcriptome analyses were conducted in male GLP-1R-/- and wild-type control mice. Analyses were performed 6 hours after a single s.c. dose of exendin-4 (1.0mg/kg s.c.), following 18 hours of two doses of exendin-4 (1.0 mg/kg s.c., administered at 0 and 9 hours), and in untreated controls. Brunners glands were isolated by laser capture micro dissection and extracted total RNA was used for microarray profiling.
