INTRODUCTION: Glucagon-like peptide-1 (GLP-1) receptor agonists are used successfully in the treatment of patients with type 2 diabetes as they are associated with low hypoglycemia rates, weight loss and improved glycemic control. This study compared, in the Spanish setting, the cost-effectiveness of liraglutide 1.8 mg versus lixisenatide 20 μg, both GLP-1 receptor agonists, for patients with type 2 diabetes who had not achieved glycemic control targets on metformin monotherapy. METHODS: The IMS CORE Diabetes Model was used to project clinical outcomes and costs, expressed in 2015 Euros, over patient lifetimes...

INTRODUCTION: While metformin (MET) is the most widely prescribed antidiabetic drug worldwide, its beneficial effects in Psammomys obesus (P. obesus), a rodent model that mimics most of the metabolic features of human diabetes, have not been explored thoroughly. Here, we sought to investigate whether MET might improve insulin sensitivity, glucose homeostasis, lipid profile as well as cellular redox and energy balance in P. obesus maintained on a high energy diet (HED). MATERIALS AND METHODS: P...

This communication hypothesises a rule of two thirds which seems to operate in Indian diabetes epidemiology. Two thirds of all persons with dysglycemia are prediabetic; two thirds of all persons with diabetes are diagnosed to have the condtion; and two thirds are diagnosed before the age of 50 years. Two thirds of people with diabetes have concomitant hypetension or dyslipidemia; two thirds do not get their HbA1c assessed; and two thirds of those who do, do not achiev target values. Yet, two thirds of people with diabetes report satisfactory psychosocial health and quality of life, and adherence to dietary therapy and medication...

AIMS: Despite guideline recommendations, many patients with type 2 diabetes on oral antidiabetic drugs (OADs) whose HbA1c results remain above target do not experience timely treatment intensification. This study uses the Archimedes Model® to estimate the consequences of delays in OAD treatment intensification on glycemic control and long-term outcomes at 5 and 20 years. MATERIALS AND METHODS: Using real world data, we modeled a cohort of hypothetical patients with HbA1c ≥8%, on metformin, with no history of insulin use...

The anti-diabetes drug metformin has been shown to have anti-neoplastic effects in several tumor models through its effects on energy metabolism and protein synthesis. Recent studies show that metformin also targets Hedgehog (Hh) signaling, a developmental pathway re-activated in several tumor types, including prostate cancer (PCa). Furthermore, we and others have shown that Hh signaling is an important target for radiosensitization. Here, we evaluated the combination of metformin and the Hh inhibitor GANT61 (GLI-ANTagonist 61) with or without ionizing radiation in three PCa cell lines (PC3, DU145, 22Rv1)...

Metabolic vulnerability is associated with age-related diseases and concomitant co-morbidities, which include obesity, diabetes, atherosclerosis and cancer. Most of the health problems we face today come from excessive intake of nutrients and drugs mimicking dietary effects and dietary restriction are the most successful manipulations targeting age-related pathways. Phenotypic heterogeneity and individual response to metabolic stressors are closely related food intake. Understanding the complexity of the relationship between dietary provision and metabolic consequences in the long term might provide clinical strategies to improve healthspan...

BACKGROUND: Metformin, an FDA-approved drug for the treatment of Type II diabetes, has emerged as a promising anti-cancer agent. Other biguanide analogs, including buformin and phenformin, are suggested to have similar properties. Although buformin was shown to reduce mammary tumor burden in carcinogen models, the anti-cancer effects of buformin on different breast cancer subtypes and the underlying mechanisms remain unclear. Therefore, we aimed to investigate the effects of buformin on erbB-2-overexpressing breast cancer with in vitro and in vivo models...

Current drug therapy fails to reduce lung destruction of chronic obstructive pulmonary disease (COPD). AMP-activated protein kinase (AMPK) has emerged as an important integrator of signals that control energy balance and lipid metabolism. However, there are no studies regarding the role of AMPK in reducing inflammatory responses and cellular senescence during the development of emphysema. Therefore, we hypothesize that AMPK reduces inflammatroy responses, senescence, and lung injury. To test this hypothesis, human bronchial epithelial cells (BEAS-2B) and small airway epithelial cells (SAECs) were treated with cigarette smoke extract (CSE) in the presence of a specific AMPK activator (AICAR, 1 mM) and inhibitor (Compound C, 5 μM)...

OBJECTIVE: Perturbations in the insulin-like growth factor (IGF) system may contribute to the accelerated cardiovascular disease (CVD) that occurs in patients with type 2 diabetes (T2D). However, it remains unknown whether the IGF system is also involved in the development of early, subclinical CVD. We characterised the IGF system in T2D patients and matched controls and examined associations with markers of subclinical target organ damage. METHODS: The study included 99 patients with recently diagnosed T2D and 99 age- and sex-matched controls...

Mammalian target for rapamycin complex 1 (mTORC1) is a common target for the action of immunosuppressant macrolide rapamycin and glucose lowering metformin. Inhibition of mTORC1 can exert both beneficial and detrimental effects in different pathologies. Here we investigated the differential effects of rapamycin (1.2mg/kg/day delivered subcutaneously for six weeks) and metformin (300mg/kg/day delivered orally for 11 weeks) treatments on male Zucker diabetic fatty (ZDF) rats that mimic the cardio-renal pathology of T2DM patients and progress to insulin insufficiency...

OBJECTIVE: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women, involving hyperandrogenaemia and insulin resistance. Treatment options include dexamethasone, as well as the off-label use of metformin. To evaluate the impact of those drugs on cyclic changes in endometrial development, we tested possible effects of metformin and dexamethasone on endometrial stromal cells decidualisation, proliferation, and gene regulation in a hyperandrogenaemic microenvironment in vitro...

Metformin, a widely prescribed drug for treating type II diabetes, is one of the most extensively recognized metabolic modulators which has shown an important anti-cancer property. However, fairly amount of clinical trials on its single administration have not demonstrated a convincing efficiency yet. Thus, recent studies tend to combine metformin with clinical commonly used chemotherapeutic drugs to decrease their toxicity and attenuate their tumor resistance. These strategies have displayed promising clinical benefits...

Proteinuria (albuminuria) plays a crucial role in the etiology of chronic kidney disease (CKD) via alteration of multiple signaling pathways and cellular process in renal cells. The objectives of this study are to investigate the effects of activation of the energy-sensing molecule AMP-activated kinase (AMPK) in renal cells using metformin on endoplasmic reticulum (ER) stress, AKT, mTOR, epithelial-to-mesenchymal transition (EMT), autophagy and apoptosis that are thought to mediate renal cell injury during proteinuria, and to dissect the AMPK- and non-AMPK mediated effects of metformin using an in vitro model of albumin-induced renal cell injury...

Arterial stiffness, the expression of reduced arterial elasticity, is an effective predictor of cardiovascular disorders. Oxidative stress is an imbalance between exposure to toxic reactive oxygen species (ROS) and antioxidant systems. The increase in reactive nitrogen species (RNS) is termed nitrosative stress. We review the main mechanisms and products linking arterial stiffness with oxidative and nitrosative stress in several disorders, focusing on recent experimental and clinical data, and the mechanisms explaining benefits of antioxidant therapy...

Despite the considerable burden of disease associated with type 2 diabetes mellitus (T2DM), most patients are not at, or are unable to achieve, recommended glycemic targets. This is partly because of the relentless progressive nature of the disease, but it may also be attributable to the current diabetes treatment paradigm. The recommended stepwise approach may lead to frequent early treatment failure with prolonged periods of elevated glucose as a consequence of clinical inertia and delays in achieving optimal glycemic control...

Pharmaceuticals are widely used for the treatment of various physical and psychological ailments. Due to incomplete removal during sewage treatment many pharmaceuticals are frequently detected in aquatic waterways at trace concentrations. The diversity of pharmaceutical contaminants and potential for complex mixtures to occur makes it very difficult to predict the toxicity of these compounds on wildlife, and robust methods are therefore needed to explore sub-lethal effects. Metabolic syndrome is one of the most widespread health concerns currently facing the human population, and various drugs, including anti-diabetic medications and lipid- and cholesterol-lowering fibrates and statins, are widely prescribed as treatment...

Several enzymes are involved in the energy production, becoming a possible target for new anti-cancer drugs. In this paper, we used biochemical and in silico studies to evaluate the effects of two guanidine molecules, (Boc)2 -creatine and metformin, on creatine kinase, an enzyme involved in the regulation of intracellular energy levels. Our results show that both drugs inhibit creatine kinase activity; however, (Boc)2 -creatine displays a competitive inhibition, while metformin acts with a non-competitive mechanism...

Metformin, an inexpensive and well-tolerated oral agent commonly used in the first-line treatment of type 2 diabetes, has become the focus of intense research as a candidate anticancer agent. Here, we discuss the potential of metformin in cancer therapeutics, particularly its functions in multiple signaling pathways, including AMP-activated protein kinase, mammalian target of rapamycin, insulin-like growth factor, c-Jun N-terminal kinase/mitogen-activated protein kinase (p38 MAPK), human epidermal growth factor receptor-2, and nuclear factor kappaB pathways...

OBJECTIVE: Epicardial adipose tissue (EAT), the visceral fat depot of the heart, is a modifiable cardiovascular risk factor and emerging therapeutic target. Liraglutide, an analog of glucagon-like peptide-1, is indicated for the treatment of type 2 diabetes mellitus. Liraglutide has recently been shown to reduce cardiovascular risk. Nevertheless, whether liraglutide could reduce EAT is unknown. METHODS: To test the hypothesis, a 6-month randomized, open-label, controlled study was performed in 95 type 2 diabetic subjects with body mass index (BMI) ≥27 kg/m(2) and hemoglobinA1c ≤8% on metformin monotherapy...

Recently, many reports have shown that Averrhoa carambola L. (Oxalidaceae) juice (EACJ) could reduce blood glucose in humans. However, its mechanisms have not been well explored; therefore, our study aimed to investigate the beneficial effects of EACJ on hyperglycemia, hyperlipidemia and renal injury in streptozotocin (STZ)-induced diabetic mice. Those mice were injected with STZ via the tail vein (120 mg/kg body weight) and were identified as diabetic mice when the level of blood glucose was ≥ 11.1 mmol/L...
