Summary: TCF7L2 is the most potent locus for type 2 diabetes (T2D) risk and is consistently associated with the disease across diverse populations with different genetic origins. The exact mechanisms by which TCF7L2 affects T2D are still not well understood.

Summary: Plasma insulin clearance plays an important role in determining plasma insulin concentration and is closely related to excess adiposity, insulin sensitivity, and type 2 diabetes. The lower insulin clearance rate observed in people with obesity is not a compensatory response to insulin resistance, but directly linked to insulin sensitivity. Additionally, postprandial insulin clearance decreases due to increased delivery of insulin to tissues that clear insulin.

Summary: Statins are commonly used to prevent cardiovascular disease events, but they also increase the risk of type 2 diabetes. These two diseases share common genetic and environmental factors. Studies have confirmed the association between statin treatment and type 2 diabetes, and the purpose of this review is to summarize the important findings and describe the mechanisms behind the increased risk.

Summary: This study re-evaluated the prevailing hypothesis that metabolic syndrome components are central to all cases of T2DM. Results showed that a significant proportion of T2DM cases did not display any components of metabolic syndrome, indicating the existence of a second, unrelated pathophysiology.

Summary: This study found that TCF7L2 genetic variants are significantly associated with a higher percentage of residual insulin-containing cells in individuals with type 1 diabetes. This suggests the existence of a subtype of type 1 diabetes that is associated with genetic factors predisposing to type 2 diabetes, and these individuals exhibit less severe beta cell loss.

Summary: The study showed that GLP-1 potentiated the glucagon-suppressive effect of glucose in a dose-dependent manner in healthy individuals and patients with type 2 diabetes. However, patients with type 1 diabetes were insensitive to the glucagonostatic effects of both glucose and GLP-1.

Summary: Carbon monoxide (CO) plays a significant role in carbohydrate metabolism by stimulating insulin secretion, protecting pancreatic β-cells, and interacting with other gasotransmitters such as nitric oxide and hydrogen sulfide. Therefore, CO may have potential therapeutic applications in treating type 2 diabetes mellitus and preventing the progression of prediabetes.

Summary: Incretin hormones, including GIP and GLP-1, are involved in the pathophysiology of type 2 diabetes. Therapeutic success has been achieved with incretin-based medications, which have the potential to improve glycaemic, cardiorenal, and body weight-related outcomes. While GIP's ability to stimulate insulin secretion is impaired in type 2 diabetes, GLP-1 can effectively stimulate insulin secretion and reduce plasma glucose concentrations.

Summary: The recent advancements in proteomic technologies have enabled the identification of biomarkers associated with future development of type 2 diabetes (T2DM) beyond known risk factors. By analyzing large longitudinal cohorts, the researchers identified specific markers with significant associations with future T2DM and explored potential causal relationships. Additionally, functional effects of a top protein association, aminoacylase 1 (ACY1), on amino acid metabolism and insulin homeostasis were discovered, highlighting potential novel disease markers and pathways in T2DM.

Summary: The study aimed to identify a lipidomic signature associated with gestational diabetes mellitus (GDM) in the postpartum period and investigate its role in the progression to type 2 diabetes (T2D). A cohort of 1,409 women who delivered a singleton baby was followed up prospectively, and their lipidome was analyzed using liquid chromatography-tandem mass spectrometry. 33 postpartum lipid species were identified to be associated with GDM, and 4 of them were also associated with incident T2D, mediating the progression from GDM to T2D. Including these lipid species improved the prediction of T2D when considering the entire follow-up period.

Summary: The study aimed to investigate the interaction of semaglutide treatment and aerobic training on pancreatic β-cell secretory function in patients with type 2 diabetes. The results showed that aerobic training increased insulin secretion, and semaglutide treatment further improved β-cell secretory function. The combination of aerobic training and semaglutide treatment synergistically enhanced β-cell secretory function.

Summary: By conducting genome-wide association studies (GWAS) on ancestrally diverse populations, we identified 237 loci associated with type 2 diabetes (T2D) and further fine-mapped these loci. The majority of T2D associations were found to be driven by a single variant. In addition, our study showed that genetic risk scores derived from ancestrally diverse populations can enhance the transferability of T2D prediction across different populations.

Summary: This study characterizes the genetic regulation of post-prandial glucose levels and identifies the heritability of non-fasting glucose levels over time. The genetic control of glucose is largely constant across fasting durations and accounting for heritability differences improves the discovery of genetic variants associated with glucose. The study also identifies genetic loci controlling the variation of glucose levels in non-fasting individuals, which can be used to predict fasting glucose levels.

Four distinct trajectories were found, with most patients achieving stable good or highly improved long-term glycaemic control. However, one-fifth of participants showed moderate or poor glycaemic control during follow-up.

Summary: The study aimed to develop and validate a recalibrated prediction model (SCORE2-Diabetes) for estimating the 10-year risk of cardiovascular disease (CVD) in individuals with type 2 diabetes in Europe. The model showed good discrimination and improvement over previous models, with risk predictions varying based on individuals' diabetes-related factors. SCORE2-Diabetes enhances the identification of individuals at higher risk of CVD in Europe.

Summary: Monogenic diabetes encompasses several clinical conditions characterized by early-onset diabetes, including neonatal diabetes, maturity-onset diabetes of the young (MODY) and diabetes-associated syndromes. It can be misdiagnosed as type 2 diabetes, and different genetic variations can lead to different forms of diabetes. Precision medicine approaches and next-generation sequencing have improved diagnosis and treatment options.

Summary: Type 2 diabetes is a metabolic disorder affecting over 537 million people worldwide, characterized by loss of pancreatic beta-cell function and insulin resistance. Long-term control of glycemia is challenging, highlighting the need for new drugs and targets to improve beta-cell function and insulin secretion. In this study, a high-throughput screening method using automated cellular assays and mass spectrometry was developed, identifying potential regulators of insulin secretion and synthesis among siRNA and chemical compounds.

Summary: Human induced pluripotent stem cells (hiPSCs) have the potential to differentiate into any cell type, making them relevant for therapeutic applications. In particular, they hold promise for obesity treatment by providing an unlimited source of brown/beige adipose progenitors (hiPSC-BAPs). However, the limited differentiation potential of brown/beige adipocytes in 2D cultures poses a challenge for clinical use.
