Summary: Oxidative stress is a deteriorating factor for pancreatic beta-cells under chronic hyperglycemia in diabetes. Cox6a2 plays a crucial role in beta-cell function and its deficiency leads to increased reactive oxygen species production, resulting in relative insufficiency of beta-cell function.

Summary: In the pursuit of bioactive phytochemicals for managing metabolic risk factors for type 2 diabetes (T2D), aspalathin, a C-glucosyl dihydrochalcone found in rooibos, has gained great attention. This review provides an overview of dietary sources, compound stability, bioavailability, and microbial biotransformation of aspalathin and its derivatives. It also discusses the role of these compounds in improving insulin resistance, gut dysbiosis, oxidative stress, inflammation, and hyperuricemia associated with T2D. Additionally, emerging targets for T2D management, such as enhancing insulin receptor signaling and reducing renal glucose reabsorption, are highlighted.

Summary: Type 2 diabetes is characterized by chronic hyperglycemia due to functional beta-cell decline and reduced insulin sensitivity. The decrease in beta-cell mass in T2D is partly attributed to beta-cell apoptosis triggered by diabetogenic situations. This review discusses the molecular mechanisms involved in pancreatic beta-cell apoptosis in such situations and potential protective pathways by glucagon-like peptide-1-based therapies.

Summary: Mechanisms contributing to myocardial ischemia-reperfusion (I/R) injury are complex, but Dexmedetomidine (DEX) shows potential in ameliorating this injury in diabetic states. DEX activates the PI3K/Akt and associated GSK-3 beta pathway, alleviates endoplasmic reticulum stress, and inhibits apoptosis. Additionally, DEX up-regulates autophagy, reduces ROS production, and inhibits inflammation via HMGB1 pathways, leading to the protection against diabetic myocardial I/R injury.

Summary: The study found that cornuside (Cor) can alleviate diabetes-induced testicular damage by modulating gut microbiota, including improving testicular lesions, increasing testis/body weight ratio, enhancing hormone levels, inhibiting apoptosis, and boosting sperm count and motility. Additionally, Cor can reverse changes in gut microbiota and impact the abundance of certain bacteria.

Summary: The study demonstrates that pancreatic acinar cells become less sensitive to tumorigenesis induced by oncogenic Kras mutations after birth, due to low expression of KRAS and its effectors. Pancreatitis induces the expression of KRAS and its effectors, requiring the activity of EGFR. Expression of C-RAF in adult pancreas is essential for pancreatic tumorigenesis.

Summary: This study transcriptionally profiled the two major human pancreatic exocrine cell types, acinar and duct cells, during experimental stress conditions. The results showed that in dedifferentiated acinar cells, cancer pathways are upregulated in which MECOM is a critical regulator that suppresses acinar cell death by permitting cellular dedifferentiation.

Summary: By utilizing single-cell RNA sequencing and CITE-seq, this study reveals the complexity of the immune landscape in glioblastomas, including conserved populations of dendritic cells and macrophages. The results indicate that microglia-derived tumor-associated macrophages dominate in newly diagnosed tumors, but are replaced by monocyte-derived TAMs in recurrences.

Summary: The study comprehensively characterized the functionality of iPSC-derived beta cells both in vitro and in vivo in humanized mice. Differentiation in microwells showed equal efficiency with rotating suspension, but with a higher success rate. In vivo transplanted beta cells demonstrated functional characteristics similar to human islets, highlighting the potential of generating islet-like organoids for diabetes research.

Summary: Prolonged culture of human islets under moderate to severe glucotoxic conditions markedly increased their glucose sensitivity and revealed a bell-shaped acute glucose response curve for changes in [Ca2+](c) and insulin secretion, with maximal stimulation at 5 or 10 mmol/l glucose and rapid inhibition above that concentration. This novel glucotoxic alteration may contribute to beta cell dysfunction in type 2 diabetes independently from a detectable increase in beta cell apoptosis.
