#1
Tabea Rüegg, Basil Caduff
Objective Lactic acidosis has been associated with the use of metformin since its introduction. The cause, however, is highly controversial. The incidence of metformin-associated lactic acidosis (MALA) is quoted at 3,0 to 16,7 cases per 100 000 patient-years according to current studies. The link between metformin and lactic acidosis in metformin therapy has been suggested to be causal and therefore, the use of metformin was restricted to type 2 diabetic patients without renal impairment. Recent studies, however, show an acceptable use and no increased incidence of lactic acidosis in chronic mild to moderate renal insufficiency, respectively...

Resveratrol and metformin have been shown to mimic some aspects of caloric restriction and exercise. However, it remains unknown if these molecules also slow age-related synaptic degeneration, as previously shown for caloric restriction and exercise. In this study, we examined the structural integrity of neuromuscular junctions (NMJs) in 2-year-old mice treated with resveratrol and metformin starting at 1 year of age. We found that resveratrol significantly slows aging of NMJs in the extensor digitorum longus muscle of 2-year-old mice...

PURPOSE: Despite robust antitumor activity in diverse preclinical models, TNF-related apoptosis-inducing ligand (TRAIL) receptor agonists have not demonstrated efficacy in clinical trials, underscoring the need to identify agents that enhance their activity. We postulated that the metabolic stress induced by the diabetes drug metformin would sensitize breast cancer cells to TRAIL receptor agonists. METHODS: Human triple (estrogen receptor, progesterone receptor, and HER2)-negative breast cancer (TNBC) cell lines were treated with TRAIL receptor agonists (monoclonal antibodies or TRAIL peptide), metformin, or the combination...

Context: Diabetic ketoacidosis has been described as a rare complication of acromegaly and may be observed in 1% of affected patients. The well described direct lipolytic effect of growth hormone results in increased availability of free fatty acids (FFA) for hepatic ketogenesis and is an important pathogenic event. More recently, ketoacidosis has been identified as an important complication of sodium-glucose-transport-protein 2 inhibitors (SGLT2i). Increased pancreatic glucagon secretion, impaired renal ketone body clearance and an increase in FFA concentrations secondary to decreased insulin concentrations are likely precipitating factors...

Albumin glycation and subsequent formation of advanced glycation end products (AGEs) correlate with diabetes and associated complications. Human Serum Albumin (HSA) was modified with D-glucose for a 40day period under sterile conditions at 37°C. Modified samples along with native HSA (unmodified) were analyzed for impairment in biochemical characteristics (fructosamine, carbonyl, thiol, lysine, arginine, hydroxymethyl furfural [HMF] content, electrochemical (electrical conductance), simulated gastric fluid assay, simulated intestinal fluid assay, spectroscopic properties (UV, fluorescence), optical (surface contact angle) and fluid dynamics (viscosity and Stokes radius)...

Metformin is a widely used drug for the treatment of type 2 diabetes (T2D). Its blood glucose-lowering effects are initially due to inhibition of hepatic glucose production and increased peripheral glucose utilization. Metformin has also been shown to have several beneficial effects on cardiovascular risk factors and it is the only oral antihyperglycaemic agent thus far associated with decreased macrovascular complications in patients with diabetes. Adenosine Monophosphate Activated-Protein Kinase (AMPK) is a major cellular regulator of lipid and glucose metabolism...

AIM: To elucidate the effects of rs2289669, an intron variant of the SLC47A1 gene, on metformin responses in Chinese people with newly diagnosed Type 2 diabetes. METHODS: We conducted a nationwide, multicentre, prospective clinical trial, in which rs2289669 was genotyped, using Sequenom, in 291 participants. The changes in HbA1c were compared among rs2289669 genotypes, and associations with rs2289669 were evaluated using linear regression analysis. RESULTS: We found that, compared with participants with a homozygous G allele, those carrying the minor A allele had significantly greater HbA1c reduction and increases in basal glucagon-like peptide-1 concentration...

Metformin is an oral hypoglycemic drug that has been shown to inhibit cancer cell proliferation via up-regulation of AMPK (AMP-activated protein kinase), and possibly inhibition of mTOR (mammalian target of rapamycin). The purpose of this study was to evaluate the effects of metformin on a feline injection site sarcoma cell line. Cells from a feline injection site sarcoma cell line were treated with metformin at varied concentrations. A dose-dependent decrease in cell viability following metformin treatment was observed, with an IC50 of 8...

We aimed to evaluate the effect of adjuvant metformin to intensive insulin therapy in patients with type 1 diabetes (T1DM). A 10 year retrospective study of 2 cohorts was performed. Cohort "MET" (n = 186) consisted of T1DM patients on adjuvant metformin for ≥ 6 months and cohort "CTR" (n = 62) consisted of T1DM patients who refused (n = 25) or adhered <6 months (n = 37) to metformin. HbA1c, BMI and daily insulin dose were registered yearly. A third cross-sectional group "REF" (n = 961) of T1DM patients not offered adjuvant metformin, was used as a reference for baseline comparison...

It is difficult to accurately evaluate the efficacy of traditional Chinese medicine (TCM), which leads to the uncertainty and complexity of dose-effect analysis. In this study we established the "Focus" mode of biomarkers to characterize the dose-effect relationship of Gegen Qinlian Decoction (GQD), a TCM formula for treating type 2 diabetes mellitus (2-DM). A rat model of 2-DM was established through high fat diet feeding combined with low-dose STZ injection. Rats with 2-DM were administered high, middle or low doses (6...

Metformin is an antidiabetic drug that is used daily by millions of patients worldwide. Metformin is able to cross the blood-brain barrier and has recently been shown to increase glucose consumption and lactate release in cultured astrocytes. However, potential effects of metformin on mitochondrial tricarboxylic acid (TCA) cycle metabolism in astrocytes are unknown. We investigated this by mapping (13) C labeling in TCA cycle intermediates and corresponding amino acids after incubation of primary rat astrocytes with [U-(13) C]glucose...
