The adipocytokine resistin impairs glucose tolerance and insulin sensitivity. Here, we examine the effect of resistin on glucose uptake in human trophoblast cells and we demonstrate that transplacental glucose transport is mediated by glucose transporter (GLUT)-1. Furthermore, we evaluate the type of signal transduction induced by resistin in GLUT-1 regulation. BeWo choriocarcinoma cells and pr...

Streptozotocin-induced (Type 1) diabetes mellitus (T1DM) in rats promotes jejunal glucose transport, but the trigger for this response remains unclear. Our recent work using euglycemic rats has implicated the enterocyte renin-angiotensin system (RAS) in control of sodium-dependent glucose transporter (SGLT1)-mediated glucose uptake across the jejunal brush border membrane (BBM). The aim of the ...

The sodium-glucose co-transporter-2-inhibitors (SGLT2I) recently gained a unique role in managing the heart failure reduced ejection fraction. These inhibitors reduce cardiovascular (CV) risk factors, including plasma glucose, blood pressure, albuminuria, body weight, and renal events long term. clinical trials proved their reducing hospitalization for HF, CV all-cause mortality, atherosclerosi...

Caenorhabditis elegans is widely used as a model for investigation of the relationships between aging, nutrient restriction and signalling via the DAF-2 (abnormal dauer formation 2) receptor for insulin-like peptides and AGE-1 [ageing alteration 1; orthologue of PI3K (phosphoinositide 3-kinase)], but the identity of the glucose transporters that may link these processes is unknown. We unexpecte...

Aim To determine the clinical and biochemical variables associated with change in HbA1c patients type 2 diabetes who start sodium-glucose linked transporter (SGLT) inhibitor therapy. Methods We performed a prospective cohort study (ACTRN12616000833460) of 48 adults (30 male, 18 female) attended tertiary hospital clinic. Fasting serum urine samples, collected during clinic visits prior to at 1, ...

SGLT2 (for "Sodium GLucose coTransporter" protein 2) is the major protein responsible for glucose reabsorption in the kidney and its inhibition has been the focus of drug discovery efforts to treat type 2 diabetes. In order to better clarify the human tissue distribution of expression of SGLT2 and related members of this cotransporter class, we performed TaqMan™ (Applied Biosystems, Foster City...

An iodinated photoaffinity label for the glucose transporter, 3-iodo-4-azidophenethylamido-7-O-succinyldeacetyl-forskolin (IAPS-forskolin), has been synthesized, purified, and characterized. The I50 for inhibition of 3-O-methylglucose transport in red blood cells by IAPS-forskolin was found to be 0.05 microM. The carrier free radioiodinated label is a highly specific photoaffinity label for the...
