Exposure to Artificial Light At Night (ALAN) results in a disruption of the circadian system, which is deleterious to health. In industrialized countries, 75% of the total workforce is estimated to have been involved in shift work and night work. Epidemiologic studies, mainly of nurses, have revealed an association between sustained night work and a 50-100% higher incidence of breast cancer.The potential and multifactorial mechanisms of the effects include the suppression of melatonin secretion by ALAN, sleep deprivation, and circadian disruption...

Maintaining the integrity of cellular membranes is critical to protecting metabolic activities and genetic information from the environment. Regulation of transport across membranes of essential chemicals, including water, nutrients, hormones and many drugs, is therefore key to cellular homeostasis and physiological processes. The two main transporter superfamilies are ATP-binding cassette (ABC) transporters that primarily function as efflux transporters, and the solute carrier (SLC) transporters. SLC transporters encompass 52 gene families with almost 400 different human transporter genes...

Protein function originates from a cooperation of structural rigidity, dynamics at different timescales, and allostery. However, how these three pillars of protein function are integrated is still only poorly understood. Here we show how these pillars are connected in Protein Tyrosine Phosphatase 1B (PTP1B), a drug target for diabetes and cancer that catalyzes the dephosphorylation of numerous substrates in essential signaling pathways. By combining new experimental and computational data on WT-PTP1B and ≥10 PTP1B variants in multiple states, we discovered a fundamental and evolutionarily conserved CH/π switch that is critical for positioning the catalytically important WPD loop...

BACKGROUND: HIV+ patients on highly active antiretroviral therapy (HAART) with suppressed viral loads have a low incidence of HIV-associated dementia, but increased prevalence of milder forms of HIV-associated neurocognitive disorders (HAND). These milder forms of HAND are often associated with minimal histological abnormalities, and their pathophysiology is unclear. Comorbidities, altered amyloid metabolism, accelerated brain aging, and activated interferon responses are suspected to play a role in HAND pathogenesis in HAART-treated persons...

Cigarette smoking (CS) is associated with vascular endothelial dysfunction in a causative way primarily related to the TS content of reactive oxygen species (ROS), nicotine, and inflammation. TS promotes glucose intolerance and increases the risk of developing type-2 diabetes mellitus (2DM) with which it shares other pathogenic traits including the high risk of cerebrovascular and neurological disorders like stroke via ROS generation, inflammation, and blood-brain barrier (BBB) impairment. Herein we provide evidence of the role played by nuclear factor erythroid 2-related factor (Nrf2) in CS-induced cerebrobvascular/BBB impairments and how these cerebrovascular harmful effects can be circumvented by the use of metformin (MF; a widely prescribed, firstline anti-diabetic drug) treatment...

AIMS: Despite guideline recommendations, many patients with type 2 diabetes on oral antidiabetic drugs (OADs) whose HbA1c results remain above target do not experience timely treatment intensification. This study uses the Archimedes Model® to estimate the consequences of delays in OAD treatment intensification on glycemic control and long-term outcomes at 5 and 20 years. MATERIALS AND METHODS: Using real world data, we modeled a cohort of hypothetical patients with HbA1c ≥8%, on metformin, with no history of insulin use...

INTRODUCTION: Magnesium is an essential cation playing a crucial role in many physiological functions and its imbalance is associated with greater number of pathological situations. Oxidative stress is usually increased due to decreased essential nutrients. Hence, any imbalance of essential nutrients like serum magnesium can significantly play a role in the pathobiology of periodontitis in the presence of diabetes, as diabetes and chronic periodontitis are two chronic diseases that have been biologically linked...

INTRODUCTION: Geriatric population is more prone for various chronic and recurrent illnesses like diabetes mellitus, hypertension, IHD, arthritic, neurodegenerative, gastrointestinal, ocular, genitourinary, respiratory disorders etc., which may require chronic medication with multiple drugs. Poor compliance in this age group accounts for medication wastage with increased cost of healthcare and substantial worsening of the disease with disability or death. Most of the human and economic costs associated with non adherence can be avoided by improving medication adherence...

The anti-diabetes drug metformin has been shown to have anti-neoplastic effects in several tumor models through its effects on energy metabolism and protein synthesis. Recent studies show that metformin also targets Hedgehog (Hh) signaling, a developmental pathway re-activated in several tumor types, including prostate cancer (PCa). Furthermore, we and others have shown that Hh signaling is an important target for radiosensitization. Here, we evaluated the combination of metformin and the Hh inhibitor GANT61 (GLI-ANTagonist 61) with or without ionizing radiation in three PCa cell lines (PC3, DU145, 22Rv1)...

Endoplasmic reticulum (ER) stress-induced apoptosis plays an important role in a range of neurological disorders, such as neurodegenerative diseases, spinal cord injury, and diabetic neuropathy. Valproate (VPA), a typical antiepileptic drug, is commonly used in the treatment of bipolar disorder and epilepsy. Recently, VPA has been reported to exert neurotrophic effects and promote neurite outgrowth, but its molecular mechanism is still unclear. In the present study, we investigated whether VPA inhibited ER stress and promoted neuroprotection and neuronal restoration in SH-SY5Y cells and in primary rat cortical neurons, respectively, upon exposure to thapsigargin (TG)...

Metabolic vulnerability is associated with age-related diseases and concomitant co-morbidities, which include obesity, diabetes, atherosclerosis and cancer. Most of the health problems we face today come from excessive intake of nutrients and drugs mimicking dietary effects and dietary restriction are the most successful manipulations targeting age-related pathways. Phenotypic heterogeneity and individual response to metabolic stressors are closely related food intake. Understanding the complexity of the relationship between dietary provision and metabolic consequences in the long term might provide clinical strategies to improve healthspan...

Glucokinase (GK) plays a critical role for maintaining glucose homeostasis with regulating glucose uptake in liver and insulin secretion in pancreas. GK activators have been reported to decrease blood glucose levels in patients with type 2 diabetes mellitus. However, clinical development of GK activators has failed due to the loss of glucose-lowering effects and increased plasma triglyceride levels after chronic treatment. Here, we generated a novel GK activator, TMG-123, examined its in vitro and in vivo pharmacological characteristics, and evaluated its risks of aforementioned clinical issues...

Little is known about the relationships between patient factors and the antihyperglycemic agents that have been prescribed as initial therapy by diabetes specialists for patients with type 2 diabetes. Moreover, there has been little clarification of the subsequent usage patterns and related factors that influenced the continuation or discontinuation of the drug or the addition of another drug. To provide information on these issues, we evaluated the clinical characteristics of Japanese patients with type 2 diabetes for whom different types of oral hypoglycemic agents (i...
