Glucose And Lipid Metabolism

Type 2 diabetes mellitus (T2DM) is a chronic disease characterized by hyperglycemia and dyslipidemia caused by impaired insulin secretion and resistance of the peripheral tissues. A major pathogenesis of T2DM is obesity-associated insulin resistance. Gynura divaricata (L.) DC. (GD) is a natural plant and has been reported to have numerous health-promoting effects on both animals and humans. In this study, we aimed to elucidate the regulatory mechanism of GD improving glucose and lipid metabolism in an obesity animal model induced by high-fat and high-sugar diet in combination with low dose of streptozocin and an insulin-resistant HepG2 cell model induced by dexamethasone. The study showed that the water extract of GD (GD extract A) could significantly reduce fasting serum glucose, reverse dyslipidemia and pancreatic damage, and regulate the body weight of mice. We also found that GD extract A had low toxicity in vivo and in vitro. Furthermore, GD extract A may increase glucose consumption in insulin-resistant HepG2 cells, markedly inhibit NF-κB activation, and decrease the impairment in signaling molecules of insulin pathway, such as IRS-1, AKT, and GLUT1. Overall, the results indicate that GD extract A is a promising candidate for the prevention and treatment of T2DM.

A sex difference of carbohydrate and lipid metabolism disorders in rats with type 2 diabetes has been studied. It was established that type 2 diabetes leads to a more pronounced deterioration in carbohydrate toleranceand insulin sensitivity in males compared to female rats, but the sex doesn’t affect basal glycemia and fructosamine levels. It was found that the increase of body weight and visceral fat in rats with type 2 diabetes is moremanifested in females than in males. It has been determined that hypertriglyceridemia is higher in diabeticmales compared to diabetic females, and the level of common lipids in the liver, both intact females and femaleswith type 2 diabetes, is lower than that of the males. The obtained results indicate a more expressive impairment of glucose and lipid metabolism in males compared to females with type 2 diabetes

Insulin Resistant State

Osteoarthritis (OA) and type 2 diabetes mellitus (T2D) are two of the most widespread chronic diseases. OA and T2D have common epidemiologic traits, are considered heterogenic multifactorial pathologies that develop through the interaction of genetic and environmental factors, and have common risk factors. In addition, both of these diseases often manifest in a single patient. Despite differences in clinical manifestations, both diseases are characterized by disturbances in cellular metabolism and by an insulin-resistant state primarily associated with the production and utilization of energy. However, currently, the primary cause of OA development and progression is not clear. In addition, although OA is manifested as a joint disease, evidence has accumulated that it affects the whole body. As pathological insulin resistance is viewed as a driving force of T2D development, now, we present evidence that the molecular and cellular metabolic disturbances associated with OA are linked to an insulin-resistant state similar to T2D. Moreover, the alterations in cellular energy requirements associated with insulin resistance could affect many metabolic changes in the body that eventually result in pathology and could serve as a unified mechanism that also functions in many metabolic diseases. However, these issues have not been comprehensively described. Therefore, here, we discuss the basic molecular mechanisms underlying the pathological processes associated with the development of insulin resistance; the major inducers, regulators, and metabolic consequences of insulin resistance; and instruments for controlling insulin resistance as a new approach to therapy.

Recent studies have demonstrated the importance of bone as an endocrine organ that produces biologically active substances, which regulate both local bone metabolism and metabolic functions throughout the body. In the process of bone remodeling (formation/destruction), the active cells secrete specific biomarkers that help detect osteometabolic dysfunction. Among bone hormones, osteocalcin plays an important role as a coordinator of bone modeling processes, energy homeostasis, metabolism of glucose, lipids and minerals. Osteocalcin is a structural protein of the bone matrix, which is synthesized by osteoblasts and enters the bloodstream in the process of bone resorption. The level of osteocalcin in the serum is used as a specific marker of bone formation. Osteocalcin promotes pancreatic β-cell proliferation and insulin secretion, and also affects the insulin sensitivity of peripheral tissues. The inverse association of glycemia with the level of osteocalcin was revealed. Patients with type 2 diabetes mellitus usually have normal or even slightly elevated bone mineral density compared to age-appropriate controls. Decreased bone quality and increased risk of fractures are associated with changes in bone microarchitecture and local humoral environment. An imbalance in osteoblast/osteoclast activity may be due to oxidative stress and the accumulation of glycosylation end products, which contributes to chronic inflammation and bone resorbtion in patients with diabetes. It is shown that the level of osteocalcin in the blood serum is significantly reduced compared to healthy controls, both in patients with type 1 diabetes mellitus and, especially, in type 2 diabetes mellitus. Given the importance of developing new approaches to the diagnosis and correction of metabolic disorders in diabetic patients, the study of the influence of bone hormones on hormonal and metabolic parameters and bone status, including the risk of fractures, remains relevant in modern diabetology.

Background and Aim. Studies have suggested that brain-derived neurotrophic factor (BDNF) plays a role in glucose and lipid metabolism and inflammation. The aim of this study was to evaluate the relationship between serum BDNF levels and various metabolic parameters and inflammatory markers in patients with type 2 diabetes mellitus (T2DM).Materials and Methods. The study included 88 T2DM patients and 33 healthy controls. Fasting blood samples were obtained from the patients and the control group. The serum levels of BDNF were measured with an ELISA kit. The current paper introduces a receiver-operating characteristic (ROC) generalization curve to identify cut-off for the BDNF values in type 2 diabetes patients.Results. The serum levels of BDNF were significantly higher in T2DM patients than in the healthy controls (206.81 ± 107.32 pg/mL versus 130.84 ± 59.81 pg/mL;P<0.001). They showed a positive correlation with the homeostasis model assessment of insulin resistance (HOMA-IR) (r=0.28;P<0.05), the triglyceride level (r=0.265;P<0.05), and white blood cell (WBC) count (r=0.35;P<0.001). In logistic regression analysis, age (P<0.05), body mass index (BMI) (P<0.05), C-reactive protein (CRP) (P<0.05), and BDNF (P<0.01) were independently associated with T2DM. In ROC curve analysis, BDNF cut-off was 137.Conclusion. The serum BDNF level was higher in patients with T2DM. The BDNF had a cut-off value of 137. The findings suggest that BDNF may contribute to glucose and lipid metabolism and inflammation.

AbstractThis study was performed to elucidate the potential influence of He Qi San (HQS) on glucose and lipid metabolism in type 2 diabetes mellitus (T2DM) patients with phlegm-blood stasis syndrome (PBSS), and to determine DNA methylation changes. Sixty T2DM patients with PBSS were randomly divided into control and HQS groups. The control group received conventional treatments, and the HQS group received conventional treatments plus HQS. Glucose metabolism (FPG, 2hPG, FINS, and HbA1c) and lipid metabolism indexes (TG, TC and LDL-C) were determined. Genes with differential DNA methylation were subjected to GO and KEGG analyses. Glucose and lipid metabolism indexes in both groups were reduced, but were much more pronounced in the HQS group. Differential promoter CpG methylation regions were identified in 682 genes, including 426 genes with high-CpG promoters, 150 genes with intermediate CpG promoters, and 106 genes with low CpG promoters. Genes with differential DNA methylation were mainly enriched in the AMPK and insulin signaling pathways, terpenoid backbone biosynthesis, and renin secretion. We concluded that HQS remarkably improved indexes of glucose and lipid metabolism in T2DM patients with PBSS through regulating the DNA methylation of genes in the AMPK and insulin signaling pathways and terpenoid backbone biosynthesis.
