The crude polysaccharide was extracted from Cordyceps militaris. Material ratio of powder and water was 1:10. The polysaccharide was successively purified by Sevag and chromatography on Sephadex G-100 column to produce a polysaccharide fraction termed CBPS-II. The average molecular weight of CBPS-II was 1.273 × 103 kDa. The study was conducted to investigate the hypoglycemic effect of Cordyceps militaris polysaccharide on diabetic mice. Analysis of the clinical chemistry of the serum samples included serum creatinine (CRE), urea nitrogen (BUN), triglyceride (TG) and total cholesterol (TC)...

Aim Scutellariae Radix (SR) and Coptidis Rhizoma (CR) have often been combined to cure type 2 diabetes mellitus (T2DM) in the clinical practice for over thousands of years, but their compatibility mechanism is not clear. Mitogen-activated protein kinase (MAPK) signaling pathway has been suggested to play a critical role during the process of inflammation, insulin resistance, and T2DM. This study was designed to investigate their compatibility effects on T2DM rats and explore the underlying mechanisms by analyzing the metabolic profiling and MAPK/PI3K/Akt signaling pathway...

Type 2 diabetes mellitus (T2DM) is a metabolic disease characterized by dysfunction of glycolipid metabolism. YLTZ is used to treat hyperlipidemia, yet its hypolipidemic and hypoglycemic mechanism on T2DM are unknown. Thus, UPLC/TOF/MS was applied in this study to identify the potential bio-markers, and deduce the possible metabolic pathways. According to bio-indexes, the increased blood lipid levels, including TC, TG, LDL and FA, and the decreased HDL, the elevated glucose, reduced insulin level and impaired OGTT were observed in diabetic rat model...

Sanhuang Xiexin Tang (SXT), a classic prescription, has been clinically used to cure diabetes for thousands of years, but its mechanism remains unclear. Here, a systematic in-depth research was performed to unravel how it worked by the signaling pathway and metabonomics analysis. Our studies were conducted using high-fat diets (HFD) and streptozocin (STZ)-induced type 2 diabetes mellitus (T2DM) rats. The blood glucose was measured by a glucose-meter. Protein contents were determined by western blotting or ELISA and mRNA expression was identified by RT-PCR analysis...

With the improvement of living standards and a change in lifestyle, the incidence of type 2 diabetes mellitus (T2DM) is increasing. Its etiology is too complex to be completely understand yet. Metabonomics techniques are used to study the changes of metabolites and metabolic pathways before and after the onset of diabetes and make it more possible to further understand the pathogenesis of T2DM and improve its prediction, early diagnosis, and treatment. In this review, we summarized the metabonomics study of T2DM in recent years and provided a theoretical basis for the study of pathogenesis and the effective prevention and treatment of T2DM...

Fenugreek is a well-known medicinal plant used for treatment of diabetes. In this study, the antidiabetic effect of fenugreek flavonoids was investigated by metabonomics based on ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS). Fenugreek flavonoids were purified using polyamide resin and D101 macroporous adsorption resin, characterized by UPLC-Q-TOF-MS, and administered to streptozotocin (STZ)-induced diabetic rats for 28 days. Pharmacological study results indicated that fenugreek flavonoids exerted a strong antidiabetic effect characterized by significant reduction of fasting blood glucose (P < 0...

Although previous studies have reported the protective effect of glucagon-like peptide-1 (GLP-1) in diabetes nephropathy, the molecular mechanism such as nephroprotection remains elusive. In this study, we explored the molecular mechanism of exendin-4 as an GLP-1 receptor agonist for the treatment of tert-butyl hydroperoxide (t-BHP)-induced injury in mouse glomerulus mesangial cells (SV40 MES 13 cells) via an NMR-based metabonomic analysis. We found that exendin-4 protected mesangial cells from t-BHP-mediated toxicity, decreased the percentage of t-BHP-treated cells undergoing apoptosis, and restored glucose consumption in the t-BHP-treated group...

Our previous research obtained Litchi chinensis Sonn. seeds extract (LSE) which showed hypoglycaemic effects on type 2 diabetes (T2D) rats. In order to understand the detailed pathogenesis of diabetes intervened by LSE, the metabonomics strategy was used. As a result, LSE decreased the insulin resistance index and the levels of glucose in urine through elevating the mRNA level of insulin, while decreasing the expression of glucagon to enhance the function of the pancreas. Meanwhile, LSE regulated the glucose and fatty acid metabolisms via increasing the expression of glucose transporter (Glu) 2, Glu4, insulin receptor (IR), and IR substrate-2 (IRS2)...

Accumulating investigations have focused on the severity of central nervous system (CNS) complications in diabetic patients. The effects of the high glucose (HG) probably attribute to the metabolic disturbances in CNS. Astrocytes, with powerful ability of metabolic regulation, play crucial roles in physiological and pathological processes in CNS. Hence, an in-depth analysis as to metabolic alterations of astrocytes exposure to HG would facilitate to explore the underlying pathogenesis. In this study, the 1 H NMR-based metabonomic approach was performed to characterize the metabolic variations of intracellular metabolites and corresponding culture media in a time-dependent manner...
