Currently, the clinical dynamics of glucagon needs to be revised based on previous data obtained from conventional glucagon radioimmunoassays. In this study, we evaluated plasma glucagon levels in type 1 diabetes patients using a newly-developed sandwich enzyme-linked immunosorbent assay (ELISA), and its association with clinical parameters and markers of diabetes complications were statistically assessed. The plasma glucagon level in 77 Japanese type 1 diabetes patients was 28.1±17.7 pg/mL, and comparable to that reported previously for type 2 diabetes patients. However, the values were widely spread and did not correlate with plasma glucose values. Additionally, the average glucagon levels in patients in a hypoglycemic state (glucose level <80 mg/dL) did not increase (21.7±12.2 pg/mL). The average glucagon level of patients experiencing hypoglycemia unawareness was significantly lower. Plasma glucagon levels evaluated using the new ELISA were dysregulated in type 1 diabetes patients in respect of plasma glucose levels, suggesting dysregulation of secretion.

Glucagon-like peptide-1 (GLP-1) is rapidly degraded by the enzyme dipeptidyl peptidase 4 (DPP-4), which exists in a soluble form in plasma and a membrane-bound form. Whether measurement of plasma DPP-...
Cancer therapy is selected by individual oncology providers. For adolescent and young adults (AYAs), the type of provider, adult or pediatric, and medical facility type, non- or academic, influence re...
Blackcurrants are berries that contain high levels of anthocyanins, particularly delphinidin 3-rutinoside (D3R). Several studies have reported that the consumption of blackcurrant extract (BCE) lowers...
We aim to investigate the relationship between serum somatostatin (SST) levels and glucose-lipid metabolism at various stages of glucose tolerance in the Jino ethnic minority (n=111) and Han populatio...
We aimed to evaluate the effectiveness of an adult-based adolescent and young adult (AYA) cancer program by assessing patient satisfaction and whether programming offers added incremental benefit beyo...
The most prevalent monogenetic diabetic subtype is named maturity onset diabetes of the young type (MODY3) or hepatocyte nuclear factor 1α (HNF1A)-diabetes. The aim of this study is to ev...
In normal physiology, glucagon from pancreatic alpha cells plays an important role in maintaining glucose homeostasis via its regulatory effect on hepatic glucose production. Patients with...
The purpose of this study is to determine the efficacy and safety of nasal glucagon compared to intramuscular (IM) glucagon for treatment of insulin-induced hypoglycemia in Japanese partic...
This is a blinded, randomized crossover study to compare the safety and efficacy of G-Pen™ (glucagon injection) to Lilly Glucagon (glucagon for injection [rDNA origin]) for hypoglycemia ...
The aim of this study is to investigate the effects of antagonising GIP after a meal on plasma levels of glucagon. 10 participants are going through four experimental days each, where they...
A species of FLAVIVIRUS, one of the Japanese encephalitis virus group (ENCEPHALITIS VIRUSES, JAPANESE), found in Australia and New Guinea. It causes a fulminating viremia resembling Japanese encephalitis (ENCEPHALITIS, JAPANESE).
A species of FLAVIVIRUS, one of the Japanese encephalitis virus group (ENCEPHALITIS VIRUSES, JAPANESE), which is the etiological agent of Japanese encephalitis found in Asia, southeast Asia, and the Indian subcontinent.
Peptides derived from proglucagon which is also the precursor of pancreatic GLUCAGON. Despite expression of proglucagon in multiple tissues, the major production site of glucagon-like peptides (GLPs) is the INTESTINAL L CELLS. GLPs include glucagon-like peptide 1, glucagon-like peptide 2, and the various truncated forms.
A pyrazine-derived DIPEPTIDYL-PEPTIDASE IV INHIBITOR and HYPOGLYCEMIC AGENT that increases the levels of the INCRETIN hormones GLUCAGON-LIKE PEPTIDE-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). It is used in the treatment of TYPE 2 DIABETES.
A type of pancreatic cell representing about 5-20% of the islet cells. Alpha cells secrete GLUCAGON.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
