Improved glycemic control with minimal systemic metformin exposure: Effects of Metformin Delayed-Release (Metformin DR) targeting the lower bowel over 16 weeks in a randomized trial in subjects with type 2 diabetes.

Metformin use is restricted in patients with renal impairment due to potential excess systemic accumulation. This study evaluated the glycemic effects and safety of metformin delayed-release (Metformin DR), which targets metformin delivery to the ileum to leverage its gut-based mechanisms of action while minimizing systemic exposure.

Induction of uterine hyperplasia after cafeteria diet exposure.

Our aim was to evaluate whether chronic administration of CAF affects the uterus and induces the morphological and molecular changes associated with endometrial hyperplasia. Female Wistar rats exposed to CAF from weaning for 20 weeks displayed increased energy intake, body weight and fat depots, but did not develop metabolic syndrome. The adult uteri showed an increase in glandular volume fraction and stromal area. The epithelial proliferation rate and protein expression of oestrogen receptor alpha (ERα) w...

Prevalence of Endometrial Cancer or Atypical Hyperplasia Diagnosed Incidentally in Infertility Clinic.

Metformin-Induced Lactic Acidosis: A Case Study.

Metformin is the first line management for patients with Type 2 diabetes mellitus. Metformin-induced lactic acidosis (MALA) is a severe side effect of metformin in high doses. However, there have not been many reported cases of MALA. The threshold metformin concentration needed to induce lactic acidosis is still not fully understood. It is important for physicians to measure metformin levels upon admission in Type 2 diabetes patients who take metformin and present with suspected lactic acidosis. We prese...

Association of metformin administration with gut microbiome dysbiosis in healthy volunteers.

Metformin is a widely used first-line drug for treatment of type 2 diabetes. Despite its advantages, metformin has variable therapeutic effects, contraindications, and side effects. Here, for the very first time, we investigate the short-term effect of metformin on the composition of healthy human gut microbiota.

Favorable outcomes of metformin on coronary microvasculature in experimental diabetic cardiomyopathy.

Although metformin is widely prescribed in diabetes, its use with associated cardiac dysfunction remains debatable. In the current study, we investigated the effect of metformin on coronary microvasculature in experimental diabetic cardiomyopathy (DCM) induced by streptozotocin. Administration of metformin after induction of DCM, reversed almost all cardiomyocyte degenerative changes induced by DCM. Metformin diminished the significantly increased (p 

Maternal obesogenic diet induces endometrial hyperplasia, an early hallmark of endometrial cancer, in a diethylstilbestrol mouse model.

Thirty-eight percent of US adult women are obese, meaning that more children are now born of overweight and obese mothers, leading to an increase in predisposition to several adult onset diseases. To explore this phenomenon, we developed a maternal obesity animal model by feeding mice a diet composed of high fat/ high sugar (HF/HS) and assessed both maternal diet and offspring diet on the development of endometrial cancer (ECa). We show that maternal diet by itself did not lead to ECa initiation in wildtype...

Clinical and Genomic Crosstalk between Glucocorticoid Receptor and Estrogen Receptor α In Endometrial Cancer.

Steroid hormone receptors are simultaneously active in many tissues and are capable of altering each other's function. Estrogen receptor α (ER) and glucocorticoid receptor (GR) are expressed in the uterus, and their ligands have opposing effects on uterine growth. In endometrial tumors with high ER expression, we surprisingly found that expression of GR is associated with poor prognosis. Dexamethasone reduced normal uterine growth in vivo; however, this growth inhibition was abolished in estrogen-induced...

Thickened Endometrium in Postmenopausal Women With an Initial Biopsy of Limited, Benign, Surface Endometrium: Clinical Outcome and Subsequent Pathologic Diagnosis.

Endometrial biopsy or curetting is indicated for postmenopausal women with abnormal uterine bleeding and/or thickened endometrium. Often, endometrial biopsy or curetting yields limited benign surface endometrium, which may indicate insufficient sampling. This study addresses the clinical outcome and subsequent pathologic diagnoses in postmenopausal women who received this initial diagnosis. Among a total of 370 endometrial biopsy or curetting between 2012 and 2015, 192 (52%) were diagnosed as limited benign...

Rifampicin alters metformin plasma exposure but not blood glucose levels in diabetic tuberculosis patients.

The pharmacokinetic and clinical implications of combining metformin with rifampicin are relevant to increasing numbers of diabetic tuberculosis (TB) patients across the world and are yet unclear. We assessed the impact of rifampicin on metformin pharmacokinetics and its glucose-lowering effect in diabetic TB patients by measuring plasma metformin and blood glucose during and after TB treatment. Rifampicin increased metformin exposure: plasma AUC and C geometric mean ratio (during vs after TB treatment) wer...

OCT1-Mediated Metformin Uptake Regulates Pancreatic Stellate Cell Activity.

Metformin treatment is reported to be associated with a lower incidence of and mortality from pancreatic cancer (PC) in type 2 diabetes patients. Activated pancreatic stellate cells (PSCs) are key stroma cells responsible for pancreatic fibrogenesis and PC progression. However, little research is about the influence of metformin on PSCs. Given the potential beneficial effects of metformin on PC, pancreatic tumour stroma is an important target for new therapeutics. We observed the effects of metformin on PSC...

Ultrasound Scoring of Endometrial Pattern for Fast-Track Identification or Exclusion of Endometrial Cancer in Women with Postmenopausal Bleeding.

To evaluate the Risk of Endometrial Cancer (REC) scoring system for the prediction of high and low probability of endometrial cancer (EC) in women with postmenopausal bleeding (PMB).

Metformin blocks mitochondrial membrane potential and inhibits sperm motility in fresh and refrigerated boar spermatozoa.

Metformin is clinically used to treat diabetes. Given its role-impacting metabolism, metformin has been also added to semen cryopreservation media showing specie-dependent effects. We aimed to investigate metformin effects in both fresh (38.5°C for 2, 24 hr) and refrigerated (17°C for 10 days) boar spermatozoa. Metformin (2 hr) does not affect fresh sperm viability, membrane lipid organization nor acrosome integrity. However, metformin (24 hr) blocks sperm ΔΨm and significantly reduces % motile sper...

Metformin Is Associated with Improved Survival and Decreased Cardiac Events With No Impact on Patency and Limb Salvage After Revascularization for Peripheral Arterial Disease.

The incidence of cardiovascular and limb-specific adverse outcomes is higher in PAD patients with diabetes. Metformin is associated with improved cardiovascular morbidity and mortality. However, the effect of metformin on limb-specific outcomes is unclear. The objective of this study was to assess the effect of metformin on outcomes following intervention for PAD.

Metformin Promotes Antitumor Immunity via Endoplasmic-Reticulum-Associated Degradation of PD-L1.

Metformin has been reported to possess antitumor activity and maintain high cytotoxic T lymphocyte (CTL) immune surveillance. However, the functions and detailed mechanisms of metformin's role in cancer immunity are not fully understood. Here, we show that metformin increases CTL activity by reducing the stability and membrane localization of programmed death ligand-1 (PD-L1). Furthermore, we discover that AMP-activated protein kinase (AMPK) activated by metformin directly phosphorylates S195 of PD-L1. S195...

Disparities in the Efficacy of Metformin in Combination with Dipeptidyl Peptidase-4 Inhibitor as Initial Treatment Stratified by Dosage and Ethnicity: A Meta-Analysis.

As initial combination therapy of metformin and dipeptidyl peptidase-4 (DPP-4) inhibitor, the efficacy and safety for the use of high dose of metformin or low dose of metformin and the efficacy and safety for the combination use for Asian and Caucasian patients were not clear.

Effect of a non-systemic, orally-administered hydrogel, GS100, on metformin pharmacokinetics.

Overweight and obesity are major health concerns worldwide, and are major predisposing factors for type 2 diabetes. This single centre, Phase I, randomised, open-label, single-dose, four-arm crossover, device-drug interaction study on 24 healthy volunteers with a body mass index of 25-40 kg/m2 tested the effect of a novel, non-systemic, orally administered hydrogel (GS100) on the pharmacokinetics of the oral antidiabetic drug, metformin. When administered in both the fed and fasted states, the effect of GS1...

Progesterone, progestins and the endometrium in perimenopause and in menopausal hormone therapy.

It is well established that unopposed estrogen for hormone therapy in postmenopausal women (MHT) induces a dose-related stimulation of the endometrium associated with an increased risk of hyperplasia and endometrial cancer. Progesterone acts physiologically to counteract the proliferative effects of estradiol during the menstrual cycle. In MHT, progestogens protect the endometrium against the proliferative effects of estrogens in women with a uterus. Recent data suggest that, whereas micronized progesterone...

High dose targeted delivery on cancer sites and the importance of short-chain fatty acids for metformin's action: Two crucial aspects of the wonder drug.

Metformin is a popular anti-diabetic drug currently being explored for its role in cancer and gut microbiome amongst other areas. Recently, Adak T et al. explicatively reviewed metformin's effects as an anti-cancer drug and a gut microbiome modulator. We feel that the authors have not adequately addressed some of the key concerns around metformin in their report and in this correspondence, we seek to add some of the issues that need to be addressed by researchers.

Metformin protects against LPS-induced intestinal barrier dysfunction by activating AMPK pathway.

Metformin not only regulates energy metabolism, but also involves in many cellular processes. In this study, we investigated the effect of metformin on lipopolysaccharide (LPS)-induced intestinal barrier damage. We found that LPS treatment decreased the expression of tight junction proteins, caused pro-inflammatory response and oxidative stress in intestine. Interestingly, metformin treatments attenuated LPS-induced intestinal barrier damage, inflammation and oxidative stress. We found that metformin improv...
