Objectives.
This study aimed to explore the expression of GLP-1 receptor in hypothalamus and gastrointestinal tissues after Roux-en-Y gastric bypass (RYGB) surgery in diabetic rats.
Methods.
Male 12-week-old Wistar rats (control) and Goto-Kakizaki rats (diabetic) were randomly divided into two groups, respectively: control sham surgery group (C), control RYGB group (C + R), diabetic sham surgery group (D), and diabetic RYGB group (D + R).
Body weight and blood glucose were monitored before and after surgery every week.
Eight weeks after surgery, all rats were sacrificed and the serum fasting GLP-1 concentrations were measured by ELISA.
GLP-1R and DPP-4 expression in hypothalamus and ileum were measured by RT-PCR.
Results.
The body weight and fasting/random blood glucose in the D + R group decreased significantly compared with the D group ( P < 0.05 ).
Serum GLP-1 levels in diabetic rats treated with RYGB were higher than the corresponding sham surgery rats.
The expression of GLP-1R of hypothalamus in RYGB-treated diabetic rats was significantly higher than those of the sham surgery diabetic rats and both control group rats ( P < 0.05 ).
We found a negative correlation between hypothalamus GLP-1R mRNA and blood glucose level.
No significant difference was seen in ileum GLP-1R and DPP-4 expression among all groups.
Conclusions.
RYGB efficiently promoted serum GLP-1 levels and the expression of GLP-1 receptor in the hypothalamus in diabetic rats.
These data suggest that the hypothalamus GLP-1R may play an important role in the GLP-1 system for improving glucose homeostasis after reconstruction of the gastrointestinal tract.
