Abstract Aims: This study aimed to evaluate the effects and mechanisms of tertiary butylhydroquinone (TBHQ) on insulin resistance (IR) and diabetic liver steatosis. Methods: Male ApoE-/- mice were received streptozocin (STZ) injection and a high-sugar-high-fat diet to form type 2 diabetes mellitus (T2DM). Then, the mice were given TBHQ for six weeks. Body weight, fasting blood-glucose (FBG), postprandial blood glucose (PBG), insulin and oral glucose tolerance test (OGTT) were detected on all the mice. Hematoxylin-eosin staining and western-blot were performed to detect the morphological structure and the target proteins expression in liver tissues. In vitro, HepG2 cells were induced by HClO and insulin to develop IR. Western-blot was used to evaluate the related proteins expression. Hoechst staining was conducted to measure cell apoptosis. Results: Mice that received STZ injection and a high-sugar-high-fat diet developed T2DM. TBHQ reduced blood glucose level, improved glucose tolerance, alleviated liver steatosis in diabetic mice. Moreover, TBHQ significantly increased AMPKα2, GLUT4 and GSK3β expression, up-regulated PI3K and AKT phosphorylation level in diabetic mice liver. Notably, TBHQ down-regulated HClO and insulin-induced cell IR and inhibited cell apoptosis via AMPKα2/PI3K/AKT pathway. Conclusion: TBHQ alleviated IR and liver steatosis in T2DM mice and the mechanism may relate to AMPKα2/PI3K/AKT pathway.

Despite dietary/lifestyle modifications as well as glycemic and lipid control, non-alcoholic fatty liver disease (NAFLD) imposes a considerable risk to the patients by advancing to non-alcoholic steatohepatitis (NASH). The present investigation aims to evaluate the protective potential of FPS-ZM1, a selective inhibitor for advanced glycation end products (RAGE), against circulating indices of liver injury in high fat diet-induced diabetic mice. FPS-ZM1 at 0.5. 1, and 2 mg/kg (orally) was administered for 2 months, starting 4 months after provision of the high-fat diet. Tests for glucose homeostasis, liver injury markers, and hepatic/plasma miR-21 expressions were performed. FPS-ZM1 attenuated diabetes-induced elevations in serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamate dehydrogenase (GLD), and alpha glutathione-S-transferase (α-GST) as well as alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (GGT). It also decreased diabetes-associated elevations in serum ferritin and plasma cytokeratin 18 fragments. Additionally, FPS-ZM1 down-regulated elevated expressions of miR-21 in the liver and plasma of diabetic mice. These findings highlight the benefits of FPS-ZM in alleviating liver injury in mice evoked by high-fat diet-induced type 2 diabetes and suggest FPS-ZM1 as a new potential adjunct to the conventional diet/lifestyle modification and glycemic control in diabetics.

Type 2 Diabetic

Glucagon-like peptide 1 (GLP-1) mimetics have been approved as an adjunct therapy for glycemic control in type 2 diabetic patients for the increased insulin secretion under hyperglycemic conditions. Recently, it is reported that such agents elicit neuroprotective effects against diabetes-associated cognitive decline. However, there is an issue of poor compliance by multiple daily subcutaneous injections for sufficient glycemic control due to their short duration, and neuroprotective actions were not fully studied, yet. In this study, using the prepared exendin-4 fusion protein agent, we investigated the pharmacokinetic profile and the role of this GLP-1 mimetics on memory deficits in a high-fat diet (HFD)/streptozotocin (STZ) mouse model of type 2 diabetic mellitus. After induction of diabetes, mice were administered weekly by intraperitoneal injection of GLP-1 mimetics for 6 weeks. This treatment reversed HFD/STZ-induced metabolic symptoms of increased body weight, hyperglycemia, and hepatic steatosis. Furthermore, the impaired cognitive performance of diabetic mice was significantly reversed by GLP-1 mimetics. GLP-1 mimetic treatment also reversed decreases in GLP-1/GLP-1 receptor expression levels in both the pancreas and hippocampus of diabetic mice; increases in hippocampal inflammation, mitochondrial fission, and calcium-binding protein levels were also reversed. These findings suggest that GLP-1 mimetics are promising agents for both diabetes and neurodegenerative diseases that are associated with increased GLP-1 expression in the brain.

Potentilla discolor Bunge (PDB), a perennial herb, has been used as a traditional Chinese medicine in the therapy of many diseases. The aim of the current study was to investigate the effect of PDB water extract on systemic inflammation and gut microbiota in type 2 diabetic (T2D) mice induced by high-fat diet (HFD) and streptozotocin (STZ) injection. C57BL/6J mice were randomly divided into a normal diet (ND) group, T2D group, and PDB group (diabetic mice treated with PDB water extract at a dose of 400 mg/kg body weight). Results showed that PDB significantly decreased the levels of lipopolysaccharide (LPS) and pro-inflammatory cytokines in serum. Further investigation showed that PDB significantly reduced the ratio of Firmicutes/Bacteroidetes and the relative abundance of Proteobacteria in fecal samples of diabetic mice. In addition, PDB notably alleviated intestinal inflammation as evidenced by decreased expression of toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), nuclear factor-κB (NF-κB), and inflammatory cytokines. PDB also reversed the decreased expression of intestinal mucosal tight junction proteins including Claudin3, ZO-1, and Occludin. Meanwhile, the levels of fecal acetic acid and butyric acid and their specific receptors including G-protein-coupled receptor (GPR) 41 and 43 expression in the colon were also increased after PDB treatment. Our results indicated that PDB might serve as a potential functional ingredient against diabetes and related inflammation.
