This study was conducted to evaluate the fractions isolated from larva extract (ADLE) that exhibited anti-apoptotic and anti-inflammatory effects. A total of 13 fractions were eluted from ADLE by centrifugal chromatography (CPC), and the polar AF-13 fraction was selected, which exerted a relatively protective effect against fat-induced toxicity in INS-1 cells. AF-13 treatment of palmitate-treated INS-1 cells decreased the expression level of apoptosis-related proteins and DNA fragmentation. AF-13 also significantly inhibited the production of nitric oxide and reactive oxygen species and the triglyceride content induced by palmitate, and the effect was found to be similar to that with ADLE treatment. Palmitate upregulated the expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) through the activation of NF-κB p65; however, this effect was significantly attenuated by AF-13 treatment. In conclusion, AF-13 is one of the major components of ADLE responsible for anti-apoptotic and anti-inflammatory activities.

Dexmedetomidine suppresses glucose-stimulated insulin secretion in pancreatic β-cells.

Article Synopsis
- Proper glycemic control is important in critical care settings, as it can impact patient outcomes and is influenced by factors such as insulin secretion and glucose metabolism.
- Various perioperative drugs, particularly dexmedetomidine (DEX), are shown to suppress glucose-stimulated insulin secretion, but the mechanisms remain unclear.
- Research using pancreatic cell lines and primary cells indicates that DEX reduces insulin secretion without significantly altering other cellular processes, suggesting that it affects insulin signaling pathways and exocytosis mechanisms.

This study established a pyroptosis injury model by stimulating insulinoma cells(INS-1) of rats with high glucose(HG) and observed the impact of additional ethanol(ET) exposure on cell pyroptosis, as well as the intervention effect of salidroside(SAL). INS-1 cells were cultured and divided into a normal control group(NG), an HG group, an HG + ET(100 mmol·L~(-1)) group, and an HG + ET + SAL(1-100 μmol·L~(-1)) group. After 72 hours of treatment, cell viability was assessed using the cell counting kit-8(CCK-8) assay.

Background: Kaempferol (KPF), a flavonoid abundant in edible plants, possesses potent anti-inflammatory and antioxidant properties beneficial with notable health benefits.
Objective: To evaluate the protective effects of KPF on metabolic disturbances and pancreatic damage in a Type 1 diabetes mellitus (T1DM) mouse model.
Methods: Male C57BL/6 mice were divided into normal, T1DM, T1DM + KPF 25 mg/kg, and T1DM + KPF 50 mg/kg groups.

Environmental exposure to arsenic is associated with significant health risks, including diabetogenic effects linked to pancreatic dysfunction. The NOD-like receptor protein 3 (NLRP3) inflammasome has been implicated in various metabolic abnormalities; however, its specific role in arsenic-induced pancreatic dysfunction remains insufficiently understood. This study aimed to elucidate the involvement and underlying mechanisms of the NLRP3 inflammasome in arsenic-induced pancreatic beta cells dysfunction through in vivo and in vitro models.

The amyloid aggregation of hIAPP and the increased level of oxidative stress are closely related to the occurrence and development of type 2 diabetes (T2D). Protein tyrosine nitration is a common post-translational modification under oxidative stress conditions. We previously found that tyrosine nitrated hIAPP (3-NT-hIAPP) has higher cytotoxicity than wild type hIAPP.
