Effects of glucagon-like peptide-1 receptor agonists on secretions of insulin and glucagon and gastric emptying in Japanese individuals with type 2 diabetes: A prospective, observational study.

Aims/introduction: Differences in the glucose-lowering mechanisms of glucagon-like peptide-1 receptor agonists (GLP-1RAs) have been noted. Clarifying these differences could facilitate the choice of optimal drugs for individuals with type 2 diabetes and requires investigation in a clinical setting.

Materials And Methods: A single-arm, prospective, observational study was conducted to evaluate the effects of various GLP-1RAs on postprandial glucose excursion, secretions of insulin and glucagon as well as on the gastric emptying rate.

A novel RFX6 heterozygous mutation (p.R652X) in maturity-onset diabetes mellitus: A case report.

Heterozygous RFX6 mutation has emerged as a potential cause of maturity-onset diabetes mellitus of the young (MODY). A 16-year-old female was diagnosed with diabetes by her family doctor and was referred to our institution for genetic examination. Genetic testing revealed a novel RFX6 heterozygous mutation (NM_173560: exon17: c.

Dietary instructions focusing on meal-sequence and nutritional balance for prediabetes subjects: An exploratory, cluster-randomized, prospective, open-label, clinical trial.

Background: Although lifestyle modifications are known to be effective in type 2 diabetes (T2D) as well as in prediabetes, adherence to a healthy diet is difficult for some, and interventions of lifestyle modifications need to be revised occasionally. Meal sequence has been gaining attention as a part of a healthy diet among T2D individuals to improve glycemia and body weight. In addition, a dietary instruction program, SMART Washoku®, which can help individuals to consume a more nutritionally balanced diet, has been developed.

Low-carbohydrate diet by staple change attenuates postprandial GIP and CPR levels in type 2 diabetes patients.

Aims: The aim of this study is to investigate the effects of a low-carbohydrate staple food (i.e., low-carbohydrate bread) on glucose and lipid metabolism and pancreatic and enteroendocrine hormone secretion in comparison with meals containing normal-carbohydrate bread, without consideration of the carbohydrate content of the side dishes.

Identification and functional analysis of CBLB mutations in type 1 diabetes.

Casitas B-lineage lymphoma b (Cblb) is a negative regulator of T-cell activation and dysfunction of Cblb in rats and mice results in autoimmunity. In particular, a nonsense mutation in Cblb has been identified in a rat model of autoimmune type 1 diabetes. To clarify the possible involvement of CBLB mutation in type 1 diabetes in humans, we performed mutation screening of CBLB and characterized functional properties of the mutations in Japanese subjects.

Genetic reconstitution of autoimmune type 1 diabetes with two major susceptibility genes in the rat.

The Komeda diabetes-prone (KDP) rat is an animal model of human autoimmune type 1 diabetes. We have previously shown that two major susceptibility genes, the major histocompatibility complex (MHC) RT1(u) haplotype and Cblb (Casitas B-lineage lymphoma b) mutation, are responsible for the development of diabetes in KDP rats, suggesting a two-gene model for development of the disease. To confirm the two-gene model, we produced a congenic strain carrying mutated Cblb alleles of the KDP rat on a non-KDP genetic background harboring the RT1(u) haplotype on its MHC.
