EDENT1FI Master Protocol for screening of presymptomatic early-stage type 1 diabetes in children and adolescents.
BMJ Open
January 2025
Institute of Diabetes Research, Helmholtz Munich German Research Center for Environmental Health, Munich, Germany
Introduction: The identification of type 1 diabetes at an early presymptomatic stage has clinical benefits. These include a reduced risk of diabetic ketoacidosis (DKA) at the clinical manifestation of the disease and a significant reduction in clinical symptoms. The European action for the Diagnosis of Early Non-clinical Type 1 diabetes For disease Interception (EDENT1FI) represents a pioneering effort to advance early detection of type 1 diabetes through public health screening.

Aims: This study investigates the role of Hepatocyte Nuclear Factor 4α (HNF4α) in the adaptation of pancreatic β-cells to an HFD-induced obesogenic environment, focusing on β cell mass expansion and metabolic adaptations.
Main Methods: We utilized an HNF4α knockout (KO) mouse model, with CRE-recombinase enzyme activation confirmed through tamoxifen administration. KO and Control (CTL) mice were fed an HFD for 20 weeks.
Regulation of intestinal flora by extract ameliorates hyperglycemia in a mouse model of type 2 diabetes mellitus.

Introduction: Type 2 diabetes mellitus (T2DM) often leads to elevated blood glucose levels and lipid metabolism disorder, which is generally accompanied by dysbiosis of gut microbiota and metabolic dysfunction.
Methods: In this study, a mouse model of T2DM was established by feeding a high-fat/sucrose diet combined with injecting a low dose of streptozotocin. The aim of this study was to analyze the regulatory effect of Suaeda salsa extract (SSE) on T2DM and its effect on the intestinal flora of mice.
Angiotensin (1-7) Improves Pancreatic Islet Function via Upregulating PDX-1 and GCK: A Dose-Dependent Study in Mice.

Department of Endocrinology and Metabolism, The First Affiliated Hospital of Shantou University Medical College, Shantou, China.
This study aimed to verify the effect of angiotensin (1-7) on improving islet function and further explore the signaling pathway that may be involved in this improvement. It also aimed to explore the effects of angiotensin (1-7) on blood glucose levels, islet function, and morphological changes in db/db mice and its potential signal pathway. Forty-five db/db mice were divided randomly into a model control group and different doses of angiotensin (1-7) intervention groups (0, 150, 300, and 600 g/kg/d), while seven db/m mice were assigned as the normal control group.

Aims: This study examined the association of gravida C-peptide with progeny islet function and insulin sensitivity in the Hyperglycemia and Adverse Pregnancy Outcome Follow-up Study (HAPO FUS).
Methods: Pregnancy 3rd trimester oral glucose tolerance test (OGTT), cord blood, and offspring OGTT glucose, C-peptide and insulin at age 10-14 years were analyzed for 4,121 mother-child dyads. Gravida fasting and 1-hour C-peptide concentration correlations with cord blood and childhood C-peptide, insulin, insulinogenic index and insulin sensitivity, and insulin resistance [HOMA-IR]), were assessed by multiple linear regression.
