Emerging evidence suggests that thiazole compounds are of great interest due to their protective effect against DM. Protective effects of thiazole derivatives against hyperglycemia have been demonstrated in earlier in vitro and in vivo studies. Previously, anti-oxidant and free radical scavenging activities of 2-(4-Fluorobenzamido)-4-methylthiazole-5-carboxylicacid, a newly developed thiazole derivative (NDTD), have been well-documented. Current study investigated the pharmacological effect of NDTD on hyperglycaemia, insulin sensitivity, lipid profile, anti-inflammatory and oxidative stress markers in an animal model...

Incretin and insulin responses to nutrient loads are suppressed in persons with diabetes, resulting in decreased glycemic control. Whereas agents including sulfonylureas and Dipeptidyl peptidase-4 inhibitors (DPP4i) partially reverse these effects and provide therapeutic benefit, their modes of action limit efficacy. Because somatostatin (SST) has been shown to suppress both insulin and GLP-1 secretion through the Gi-coupled SST receptor 5 (SSTR5) isoform in vitro, antagonism of SSTR5 may improve glycemic control via intervention in both pathways...

Improvement of hyperglycemia through dietotherapy/herbal remedy is an effective approach to treating diabetes. In this study, mulberry leaf, famous for silkworm's special food and therapeutic value without any side effects, alleviated diabetes by attenuating NEFA signaling and modulating intestinal microflora. Mulberry leaf treatment significantly reduce fasting blood-glucose and HbA1c, ameliorate the blood lipid profile and improve insulin resistance in streptozotocin-induced diabetic rats. Mechanistically, we found that mulberry leaf inhibited NEFA signaling by reducing downstream signaling in the NEFA pathway, further verified by reduced PKC and improved cellular energy homeostasis based on restored expression of PGC-1α, AK2, OXPHOS and adiponectin...

BACKGROUND: Chronic and recalcitrant wounds present a significant therapeutic challenge. Amniotic tissues contain many regenerative cytokines, growth factors, and extracellular matrix molecules including proteoglycans, hyaluronic acid, and collagens I, III, and IV. Dehydrated amnion/chorion grafts are currently used to treat a variety of wounds such as diabetic foot ulcers and burns. OBJECTIVE: The investigators hypothesized that processing methodologies, dehydration, and hypothermic processing and storage of amniotic tissues would affect overall quality of wound healing; they compared dehydrated amnion/chorion (dHACM) grafts to a novel hypothermically stored amniotic membrane (HSAM) graft in a full-thickness rat wound model...

BACKGROUND/AIMS: Endoplasmic reticulum (ER) stress has emerged as a potential mechanism contributing to diabetes and its comorbidities. However, the importance of ER stress in diabetic vascular dysfunction is unclear. The purpose of this study was to examine the effects of the ER stress inhibitor, tauroursodeoxycholic acid (TUDCA), on arterial stiffness and endothelial dysfunction in type 2 diabetic mice. METHODS: Carotid and mesenteric artery endothelial function were assessed via ex vivo pressure myography, and arterial stiffness was measured by aortic pulse wave velocity...

AIMS/HYPOTHESIS: The relative contribution of T helper (Th)1 and Th17 cells in graft rejection is inconclusive, on the basis of evidence provided by different T cell-related cytokine-deficient animal models and graft types. METHODS: We used novel antigen-presenting-cell-specific Il-12p35 (also known as Il12a)-knockout (KO), IL-23p19-knockdown (KD) and IL-27p28-KD strategies to investigate T cell differentiation in islet graft rejection. RESULTS: In vitro dendritic cell-T cell coculture experiments revealed that dendritic cells from Il-12p35-KO and IL-23p19-KD mice showed reduced ability to stimulate IFN-γ and IL-17 production in T cells, respectively...

A non-invasive method of pancreatic β-cell mass measurement is needed to enhance our understanding of the pathogenesis of diabetes, facilitate the early diagnosis of this disease, and promote the development of novel therapeutics. Here, we described the synthesis of a novel indium-111 ((111)In) exendin-4 derivative, [Lys(12)(In-BnDTPA-Ahx)]exendin-4, through a process involving isothiocyanate-benzyl-DTPA (BnDTPA) and 6-aminohexanoic acid (Ahx) attached to an ɛ-amino group at the lysine-12 residue. We further evaluated the potential use of this derivative as a SPECT probe for pancreatic β-cell imaging...

The increasing incidence of obesity and diabetes due to changes in diet, earlier menarche, delayed menopause, late marriage, and declining birth rate have resulted in an increase in the number of endometrial cancer cases over the last few decades. Although surgical therapy is sufficient for early endometrial cancer, there is no effective therapy for patients with advanced and recurrent endometrial cancer. The oncogenic mechanism of endometrial cancer involves microsatellite instability (MSI) caused by dysfunction of DNA mismatch repair genes in 30% of patients...

The receptor for advanced glycation end-products (RAGE) is a multi-ligand receptor which belongs to the pattern recognition receptor family and can bind to various ligands such as advanced glycation end-products (AGEs), members of the S100 protein family, glycosaminoglycans, amyloid β peptides, high-mobility group box-1 (HMGB1) and nucleic acids through its extracellular domain. The RAGE-ligand interaction leads to the activation of MAP kinase and NF-kB signaling pathways. Further ligand-induced up-regulation of RAGE is involved in various patho-physiological situations including late diabetic complications, Alzheimer disease and several other neurodegenerative diseases...

Diabetic nephropathy is characterized by persistent albuminuria, progressive decline in GFR, and secondary hypertension. MicroRNAs are dysregulated in diabetic nephropathy, but identification of the specific microRNAs involved remains incomplete. Here, we show that the peripheral blood from patients with diabetes and the kidneys of animals with type 1 or 2 diabetes have low levels of microRNA-25 (miR-25) compared with those of their nondiabetic counterparts. Furthermore, treatment with high glucose decreased the expression of miR-25 in cultured kidney cells...

In the vascular system, the endothelial surface layer (ESL) as the inner surface of blood vessels affects mechanotransduction, vascular permeability, rheology, thrombogenesis, and leukocyte adhesion. It creates barriers between endothelial cells and blood and neighbouring cells. The glycocalyx, composed of glycoconjugates and proteoglycans, is an integral component of the ESL and a key element in inter- and intracellular communication and tissue homeostasis. In pathophysiological conditions (atherosclerosis, infection, ischemia/reperfusion injury, diabetes, trauma and acute lung injury) glycocalyx-degrading factors, i...

Obesity is a major risk factor for the development of type 2 diabetes mellitus (T2DM), and is associated with a cluster of metabolic factors that lead to poor cardiovascular outcomes. In non-alcoholic fatty liver disease (NAFLD), liver fat (triglyceride) accumulation closely mirrors adipose tissue dysfunction and insulin resistance in obesity and T2DM. It is now recognized as the most common chronic liver disease in Westernized societies, often progressing to more severe forms of the disease such as nonalcoholic steatohepatitis (NASH), or cirrhosis and hepatocellular carcinoma...

Identifying molecular mechanisms that regulate insulin expression in bone marrow-derived mesenchymal stem cells (bmMSCs) can provide clues on how to stimulate the differentiation of bmMSCs into insulin-producing cells (IPCs), which can be used as a therapeutic approach against type 1 diabetes (T1D). As repression factors may inhibit differentiation, the efficiency of this process is insufficient for cell transplantation. In this study, we used the mouse insulin 2 (Ins2) promoter sequence and performed a DNA affinity precipitation assay combined with liquid chromatography-mass spectrometry to identify the transcription factor, chicken ovalbumin upstream promoter transcriptional factor I (COUP-TFI)...

Human islet amyloid polypeptide (hIAPP) is a natively unfolded polypeptide hormone of glucose metabolism, which is co-secreted with insulin by the β-cells of the pancreas. In patients with type 2 diabetes, IAPP forms amyloid fibrils because of diabetes-associated β-cells dysfunction and increasing fibrillation, in turn, lead to failure of secretory function of β-cells. This provides a target for the discovery of small organic molecules against protein aggregation diseases. However, the binding mechanism of these molecules with monomers, oligomers and fibrils to inhibit fibrillation is still an open question...

Metformin is most widely prescribed for type 2 diabetes. Recently, evidences have shown that metformin has anticancer effects on pancreatic-, colorectal-, ovarian-, and other cancers. Because metformin has less adverse effects and is inexpensive, it could be a useful chemo-therapeutic agent with anticancer effects. In this study, we demonstrated metformin inhibited by cell proliferation, cell migration ability, clonogenic ability, and cancer stem cell population. Metformin also induced cell cycle arrest in parental-(SNU-C5), and 5-Fu resistant-colorectal cancer cell line (SNU-C5_5FuR)...

BACKGROUND: Diabetic Retinopathy is a leading cause of sight-threatening complication, which occurs due to a number of physiological and metabolic abnormalities during later stages of diabetes. Many of these abnormal changes are consistent with altered oxidative stress, inflammation, genetic set up, advanced glycation end products, and hematological changes. So the altered levels of different biomolecules related to these changes serve as important biomarkers to assess better evaluation and early treatment of this disease...

Proliferative vitreoretinal diseases such as diabetic retinopathy, proliferative vitreoretinopathy (PVR), and age-related macular degeneration are a leading cause of decreased vision and blindness in developed countries. In these diseases, retinal fibro(vascular) membrane (FVM) formation above and beneath the retina plays an important role. Gene expression profiling of human FVMs revealed significant upregulation of periostin. Subsequent analyses demonstrated increased periostin expression in the vitreous of patients with both proliferative diabetic retinopathy and PVR...

Protein folding is a process of self-assembly defined by the sequence of the amino acids of the protein involved. Additionally, proteins tend to unfold, misfold and aggregate due to both intrinsic and extrinsic causes. Human islet amyloid polypeptide (hIAPP) aggregation is an early step in diabetes mellitus. However, the aggregation of rat IAPP (rIAPP) remains an open question. Adult female Sprague-Dawley rats weighing 150-250 g were divided into two groups. The experimental group (streptozotocin [STZ]) (n = 21) received an intraperitoneal injection of a single dose of 40 mg/kg STZ...

Chronic hyperglycemia is one of the characteristic conditions associated with Diabetes Mellitus (DM), which often exerts deleterious effects on erythrocyte morphology and hemodynamic properties leading to anemia and diabetes-associated vascular complications. High glucose-induced over production of reactive oxygen species (ROS) can alter the blood cell metabolism and biochemical functions subsequently causing eryptosis (red blood cell death), yet another complication of concern in DM. Therefore, blocking high glucose-induced oxidative damage and subsequent eryptosis is of high importance in the better management of DM and associated vascular complications...
