To determine the role of glucagon action in diet-induced and genetic type 2 diabetes (T2D), we studied high-fat-diet-induced obese (DIO) and leptin receptor-defective (LepR(-/-)) rodents with and without glucagon receptors (GcgRs). DIO and LepR(-/-),GcgR(+/+) mice both developed hyperinsulinemia, increased liver sterol response element binding protein 1c, and obesity. DIO GcgR(+/+) mice develop...

UNLABELLED The risks and benefits of metformin use in patients with cirrhosis with diabetes are debated. Although data on a protective effect of metformin against liver cancer development have been reported, metformin is frequently discontinued once cirrhosis is diagnosed because of concerns about an increased risk of adverse effects of metformin in patients with liver impairment. This study in...

Our clinical study indicates esophageal adenocarcinoma patients on metformin had a better treatment response than those without metformin. However, the effects of metformin and the mechanisms of its action in esophageal cancer (EC) are unclear. EC cell lines were used to assess the effects of metformin alone or in combination with 5-fluorouracil on survival and apoptosis. RPPA proteomic array a...

conclusions compared with acarbose or metformin monotherapy, the addition of acarbose to metformin had superior antihyperglycemia efficacy and provided an efficacious and safe alternative for the treatment of type 2 diabetic rats. acarbose/metformin reduced the fasting blood glucose and glycated hemoglobin without significant changes in serum visfatin levels. background diabetes mellitus is a c...

Even though the role of fetal hyperinsulinemia in the pathogenesis of fetal macrosomia in patients with overt diabetes and gestational diabetes mellitus seems plausible, the molecular mechanisms of action of hyperinsulinemia remain largely enigmatic. Recent indications that hyperinsulinemia "primes" various tissues to the mitogenic influence of growth factors by increasing the pool of prenylate...

Type 2 diabetes mellitus is a worldwide epidemic disorder with considerable health and economic consequences. Metformin is one of the most commonly prescribed oral antidiabetic drugs. Pharmacogenetic studies showed that variants in genes related to the pharmacokinetics of metformin were associated with glucose-lowering effect of metformin. The aim of this study was to evaluate pharmacogenetic v...

INTRODUCTION Saxagliptin added to metformin extended release (XR) and uptitrated metformin XR were evaluated for their impact on daily glucose measurements and their tolerability in patients with type 2 diabetes mellitus (T2DM) inadequately controlled with metformin monotherapy. METHODS Patients aged 18-78 years on metformin 850-1,500 mg with glycated hemoglobin (HbA1c) 7.5-11.5% at screening...

Metformin is a widely prescribed antidiabetic drug associated with a reduced risk of cancer. Many studies show that metformin inhibits cancer cell viability through the inhibition of mTOR. We recently showed that antiproliferative action of metformin in prostate cancer cell lines is not mediated by AMP-activated protein kinase (AMPK). We identified REDD1 (also known as DDIT4 and RTP801), a nega...

Atypical endometrial hyperplasia has been associated with progression to endometrial cancer, the most common genital malignancy. There are multiple risk factors for endometrial cancer, such as early menarche, exogenous estrogen exposure, obesity and diabetes. Diabetics have a 3-4 fold relative risk of endometrial cancer. Also, several studies have demonstrated an association between insulin res...
