The understanding of GLP-1 receptor regulation and signal transduction will aid in the discovery of compounds that act as agonists of the GLP-1 receptor for potential use in the treatment of diabetes and will facilitate the understanding of its expression under normal and pathophysiological conditions.
To study the relationship between the GLP-1 receptor gene and NIDDM, linkage of a microsatellite polymorphism flanking the GLP-1 receptor gene with diabetes was investigated in three Caucasian families with MODY and in the nuclear families of 12 NIDDM probands.
A single administration of rAd-GLP-1 via the tail vein into streptozotocin (STZ)-induced diabetic non-obese diabetic/severe combined immunodeficient (NOD/SCID) mice resulted in remission of diabetes within 10 days; normoglycemia remained until the experiment was terminated.
Our study suggests that a DPP-IV inhibitor may prevent peripheral nerve degeneration in a diabetes-induced animal model and support the idea that GLP-1 may be useful in peripheral neuropathy.
These findings suggest that the GLP-1 pretreatment may be a new therapeutic strategy in the preventive and protective treatment during diabetes initiation and progression.
Peptide hormones of the glucagon-like peptide (GLP) family play an increasing clinical role, as reported for GLP-1 in diabetes therapy and insulinoma diagnostics.
Thus, dual agonists of the GCGR and GLP1R represent a new therapeutic approach for diabetes and obesity with the potential for enhanced weight loss and improvement in glycemic control beyond those of GLP1R agonists.
In addition, intrathecal GLP-1R agonists GLP-1(7-36) and exenatide potently alleviated formalin-, peripheral nerve injury-, bone cancer-, and diabetes-induced hypersensitivity states by 60-90%, without affecting acute nociceptive responses.
We investigated whether oral administration of human commensal bacteria engineered to secrete GLP-1(1-37) could ameliorate hyperglycemia in a rat model of diabetes by reprogramming intestinal cells into glucose-responsive insulin-secreting cells.
Of these, glucagon and GLP-1 have received the most attention because of important roles in glucose metabolism, involvement in diabetes and other disorders, and application to therapeutics.
Although the GLP-1 receptor (GLP-1R) is a validated drug target for diabetes, the importance of the GIP receptor (GIPR) for the function of beta cells remains uncertain.
Studies have showed that diabetes is one of the high risk factors of endometrial cancer; however, no reports describe the anti- or pro-cancer effect of a new kind of anti-diabetes drug, glucagon-like peptide-1 receptor agonist exenatide (exendin-4), on endometrial cancer.
The half-life of GLP-1-IgG2σ-Fc in cynomolgus monkeys was approximately 57.1 ± 4.5 h. In the KKAy mouse model of diabetes, one intraperitoneal injection of GLP-1-IgG2σ-Fc (1 mg/kg) reduced blood glucose levels for 5 days.
As a sole treatment for diabetes and used with other hypoglycemic agents, it achieves a lowering of HbA1c of up to 1%, less than several competitor GLP-1 RAs.
Therefore the present analysis was performed, using results from a network meta-analysis (NMA), to compare the cost-effectiveness of three currently available daily administered GLP-1 receptor agonists for treatment of diabetes in the UK setting.
Advances in self-administration of insulin and GLP-1 receptor agonist therapies with use of drug-device combination products have further improved the outcomes of diabetes management and quality of life for diabetic patients.
Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are used for diabetes and obesity treatment, and animal studies have indicated cognitive-enhancing effects.
