Sodium glucose linked transport

Diabetes Mellitus Type 2 (T2D) is an emerging health burden in the USand worldwide, impacting approximately 15% of Americans. Current front-line therapeutics for T2D patients include sulfonylureas that act to reduce A1C and/or fasting blood glucose levels, or Metformin that antagonizes the action of glucagon to reduce hepatic glucose production. Next generation glucomodulatory therapeutics target members of the high-affinity glucose transporter Sodium-Glucose-Linked-Transporter (SGLT) family. SGLT1 is primarily expressed in intestinal epithelium, whose inhibition reduces dietary glucose uptake, whilst SGLT2 is highly expressed in kidney - regulating glucose reabsorption...

BACKGROUND: Metabolic effects of empagliflozin treatment include lowered glucose and insulin concentrations, elevated free fatty acids and ketone bodies and have been suggested to contribute to the cardiovascular benefits of empagliflozin treatment, possibly through an improved cardiac function. We aimed to evaluate the influence of these metabolic changes on cardiac function in patients with T2D. METHODS: In a randomized cross-over design, the SGLT2 inhibitor empagliflozin (E) was compared with insulin (I) treatment titrated to the same level of glycemic control in 17 patients with type 2 diabetes, BMI of > 28 kg/m2 , C-peptide > 500 pM...

This study aimed to compare the cost-effectiveness of the new quadruple therapy regimen of adding sodium-glucose-linked transporter 2 (SGLT2) inhibitors, with standard treatment for patients with heart failure (HF) in China. From the payer's perspective, the dates of cardiovascular event recurrences were extracted from a meta-analysis including 6 trials, combined with the treatment cost for patients with HF in China to construct a Markov model. The outcomes included per capita medical costs and incremental cost-effectiveness ratio, using quality-adjusted life years (QALYs) data...

BACKGROUND: We evaluated the effect of recombinant human hepatocyte growth factor (rh-HGF) on intestinal adaptation in a rat model of short-bowel syndrome (SBS). METHODS: Sprague-Dawley rats underwent jugular vein catheterization for continuous total parenteral nutrition (TPN) and 90 % small bowel resection. The animals were divided into 3 groups: TPN/SBS (control group, n = 7), TPN/SBS/intravenous recombinant human hepatocyte growth factor (HGF) (0...

BACKGROUND: The sodium-glucose transporter-2 (SGLT-2) inhibitor dapagliflozin can improve left ventricular (LV) performance in patients with type 2 diabetes mellitus (T2DM). However, the effects on left atrial (LA) function in treatment-naïve T2DM patients remain unclear. The aim of our study was 1) to investigate the effects of 3-month treatment with dapagliflozin on LA function in treatment-naïve patients with T2DM using 4-dimensional automated LA quantification (4D Auto LAQ) and 2) to explore linked covariation patterns of changes in clinical and LA echocardiographic variables...

Immune cells and other cells respond to nutrient deprivation by the classic catabolic pathway of AMPK (Adenosine monophosphate kinase). This kinase is a pivotal regulator of glucose and fatty acids metabolism, although current evidence highlights its role in immune regulation. Indeed AMPK, through activation of Foxo1 (Forkhead box O1) and Foxo3 (Forkhead box O3), can regulate FOXP3, the key gene for differentiation and homeostasis of Tregs (T regulators lymphocytes). The relevance of Tregs in the onset of T1D (Type 1 diabetes) is well-known, while their role in the pathogenesis of T2D (Type 2 diabetes) is not fully understood yet...

BACKGROUND: Endothelial-mesenchymal transition (EndMT) plays a crucial role in promoting myocardial fibrosis and exacerbating cardiac dysfunction. Dapagliflozin (DAPA) is a sodium-glucose-linked transporter 2 (SGLT-2) inhibitor that has been shown to improve cardiac function in non-diabetic patients with heart failure (HF). However, the precise mechanisms by which DAPA exerts its beneficial effects are yet to be fully elucidated. METHODS: Isoproterenol (ISO) was used to generate a HF model in mice...

AIMS: Growth differentiation factor-15 (GDF-15) is upregulated in part in response to cardiomyocyte stretch and stress, and it exerts a protective role that is mediated by its action to suppress signalling through insulin-like growth factor (IGF) and enhance signalling through adenosine monophosphate-activated protein kinase (AMPK). Sodium-glucose cotransporter 2 (SGLT2) inhibitors improve outcomes in heart failure, which has been experimentally linked to AMPK. This study aimed at evaluating the associations of GDF-15 with baseline characteristics, the prognostic significance of GDF-15, and the effect of empagliflozin on GDF-15 in patients with heart failure with a reduced and preserved ejection fraction...

The risk of neurodegeneration was found to be increased among people with type 2 diabetes mellitus (T2DM). Brain disorders like Alzheimer's disease, Parkinson's disease, Huntington's disease, Amyotrophic lateral sclerosis, and others are considered neurodegenerative diseases and can be characterized by progressive loss of neurons. The deficiency of insulin, impaired signaling, and its resistance lead to alteration in the neuronal functioning of the brain. Insulin degrading enzyme (IDE) plays a significant role in the amyloid β metabolism, aggregation, and deposition of misfolded proteins in the brain's hippocampal and cortical neuronal regions...

INTRODUCTION: Enterocutaneous fistula is defined as an abnormal connection between the gastrointestinal tract and the skin. In addition to the early recognition and treatment of sepsis, nutritional support, wound management, the adequate replacement of lost fluids with a properly set and timely rehydration treatment, together with the control of fistula production represent the first steps in treatment management. MATERIAL AND METHODS: The authors present an overview of oral rehydration therapy, describing the properties and effects of individual solutions on fistula...

Diabetic kidney disease (DKD) is a serious complication of diabetes that can lead to end-stage kidney disease. Despite its significant impact, most research has concentrated on the glomerulus, with little attention paid to the tubulointerstitial region, which accounts for the majority of the kidney volume. DKD's tubulointerstitial lesions are characterized by inflammation, fibrosis, and loss of kidney function, and recent studies indicate that these lesions may occur earlier than glomerular lesions. Evidence has shown that inflammatory mechanisms in the tubulointerstitium play a critical role in the development and progression of these lesions...

No other class of drugs has caused as much of a stir in the last decade as sodium-glucose linked transporter 2 inhibitors (SGLT-2i) or gliflozines. At the latest since the SGLT-2i originally developed as a diabetes mellitus drug unexpectedly also showed protective effects for heart and kidney in pivotal studies, they are now the talk of the town. Although the cellular and molecular mechanisms have not yet been clarified in all details, they have revolutionized therapeutic approaches for diabetes mellitus, heart failure independent of left ventricular ejection fraction, and nephropathies based on positive data available...

Next to the skin, the peritoneum is the largest human organ, essentially involved in abdominal health and disease states, but information on peritoneal paracellular tight junctions and transcellular channels and transporters relative to peritoneal transmembrane transport is scant. We studied their peritoneal localization and quantity by immunohistochemistry and confocal microscopy in health, in chronic kidney disease (CKD) and on peritoneal dialysis (PD), with the latter allowing for functional characterizations, in a total of 93 individuals (0-75 years)...

Heart failure with preserved ejection fraction (HFpEF) is a complex and heterogeneous clinical syndrome. The prevalence is expected to increase in the coming years, resulting in heart failure with reduced ejection fraction (HFrEF). This condition poses a burden to the global health care system as the number of patients affected by this condition is constantly increasing due to a rising average lifespan. The absence of validated drugs effective in reducing hospitalization rates and mortality may reflect the impossibility of applying a one size fits all approach as in HFrEF, heading for a personalized approach...

Our study aimed to conduct a comprehensive biochemical profiling and metabolomics analysis to investigate the effects of arsenic-induced metabolic disorders, with a specific focus on disruptions in lipid metabolism, amino acid metabolism, and carbohydrate metabolism. Additionally, we sought to assess the therapeutic potential of resveratrol (RSV) as a remedy for arsenic-induced diabetes, using metformin (MF) as a standard drug for comparison. We measured the total arsenic content in mouse serum by employing inductively coupled plasma mass spectrometry (ICP-MS) after administering a 50-ppm solution of sodium arsenate (50 mg/L) in purified water...

BACKGROUND: Dapagliflozin is a reversible, highly potent, and selective Sodium-Glucose Co-Transporter-2 inhibitor indicated for the treatment of type 2 diabetes. It is generally well tolerated, with a low risk of hypoglycaemia and diabetic ketoacidosis. CASE PRESENTATION: We report a new adverse effect of dapagliflozin in a form of a transient hematuria, presenting in a 54-years-old male patient with type 2 diabetes after exercise and insufficient hydration. The process of hematuria in the patient is strongly linked with initial period of treatment...

AIM: Progression of diabetic nephropathy (DN) is linked to the dysregulated increase of adenosine and altered signaling properties. A major contribution to the maintenance of physiological extracellular adenosine levels relies on cellular uptake activity through plasma membrane nucleoside transporters. Because kidney cells are responsive to insulin, this study aims to determine how DN affects insulin regulation of the equilibrative nucleoside transporter-2 (ENT2). METHODS: Human Podocytes and rat glomeruli were used to study ENT2 regulation...

This meta-analysis aims to evaluate the impact of Sodium Glucose Transporter 2 (SGLT2) inhibitors on fractures, bone mineral density (BMD), and bone metabolism markers in type 2 diabetes mellitus (T2DM) patients. Pooled relative risk (RR) with 95% confidence interval (CI) assessed the relationship between SGLT2 inhibitors and fracture risk. Weighted mean difference (WMD) with 95% CI explored the correlation between SGLT2 inhibitors and BMD, as well as bone metabolism markers. A total of 20 randomised controlled trials (RCTs) involving 12,764 patients were analysed...

The drug metabolism and drug degradation pathways may overlap, resulting in the formation of similar constituents. Therefore, the metabolism data can be helpful for deriving safe levels of degradation impurities and improving the quality of respective pharmaceutical products. The present article contains considerations on possible links between metabolic and degradation pathways for new antidiabetic drugs such as glutides, gliflozins, and gliptins. Special attention was paid to their reported metabolites and identified degradation products...

BACKGROUND: Postoperative ileus (POI) is a major complication of abdominal surgery (AS). Impaired gut barrier mediated via Toll-like receptor 4 (TLR4) and interleukin-1 (IL-1) receptor is involved in the development of POI. Phlorizin is a nonselective inhibitor of sodium-linked glucose transporters (SGLTs) and is known to improve lipopolysaccharide (LPS)-induced impaired gut barrier. This study aimed to clarify our hypothesis that AS-induced gastric ileus is mediated via TLR4 and IL-1 signaling, and phlorizin improves the ileus...
