Abstract

Introduction: Metformin, an oral medicine used to treat type 2 diabetes, is a Glucagon-Like Peptide-1 (GLP-1) analogue, which has been demonstrated to stimulate the expression of Pancreatic duodenal homeobox-1 (Pdx-1), Insulin and Glucose transporter 2 (Glut-2) genes. In this study, the regulatory effect of metformin on beta cells function through the expression ofPdx-1, Insulin and Glut-2 genes was investigated.Materials and Methods:Pregnant C57BL/6 mice were randomly divided into 2 groups. Normal saline was given to the control group and the experimental group received 75, 150 and 250 mg/kg metformin daily by intraperitonealinjectionfrom day 8.5 of pregnancy. Half the pregnant animals were then sacrificed by cervical dislocation or day 19.5 of pregnancy and the pancreases of embryos were dissected. The other half of pregnant animals were allowed to deliver their pups and the pancreases of one day old mice were dissected. The dissected pancreases were then used for assessment of Pdx-1, Insulin and Glut-2 genes expression by semi-quantitative RT-PCR method. Results: Results showed that the administration of various doses of metformin caused no changes in the expression ofPdx-1, Insulin and Glut-2 genes compared to the control group (P>0.05).Conclusion: The regulatory effect of metformin on beta cells function might not be related to the expression of Pdx-1, Insulin and Glut-2 genes and may be related to the expression of gloconeogenesis pathway genes.
