BACKGROUND/AIMS: The sulphonylurea glibenclamide (Gli) is widely used in the treatment of type 2 diabetes. In addition to its antidiabetic effects, low incidences of certain types of cancer have been observed in Gli-treated diabetic patients. However, the mechanisms underlying this observation remain unclear. The aim of the present work was to evaluate whether obese adult rats that were chronically treated with an antidiabetic drug, glibenclamide, exhibit resistance to rodent breast carcinoma growth...

Testicular nuclear receptors 2 and 4 (TR2, TR4), also known as NR2C1 and NR2C2, belong to the nuclear receptor superfamily and were first cloned in 1989 and 1994, respectively. Although classified as orphan receptors, several natural molecules, their metabolites, and synthetic compounds including polyunsaturated fatty acids (PUFAs), PUFA metabolites 13-hydroxyoctadecadienoic acid, 15-hydroxyeicosatetraenoic acid, and the antidiabetic drug thiazolidinediones can transactivate TR4. Importantly, many of these ligands/activators can also transactivate peroxisome proliferator-activated receptor gamma (PPARγ), also known as NR1C3 nuclear receptor...

Obesity is crucially involved in many metabolic diseases, such as type 2 diabetes, cardiovascular disease and cancer. Regulating the number or size of adipocytes has been suggested to be a potential treatment for obesity. In this study, we investigated the effect of pyrocincholic acid 3β-O-β-D-quinovopyranosyl-28-O-β-D-glucopyranoside (PAQG), a 27-nor-oleanolic acid saponin extracted from Metadina trichotoma, on adipogenesis and lipid metabolism in 3T3-L1 adipocytes. The 3T3-L1 pre-adipocytes were incubated with vehicle or PAQG for 6 days in differentiation process...

OBJECTIVES: One of every four pregnant women in Chile is obese. Gestational obesity is associated with maternal metabolic complications in pregnancy (e.g., gestational diabetes, preeclampsia), but to our knowledge, there is little evidence on relationships with future metabolic risk. The aim of this study was to evaluate the association between prepregnancy obesity (prepregnancy body mass index ≥30 kg/m(2)) or excessive gestational weight gain (GWG; according to the 2009 recommendations from the Institute of Medicine), and maternal metabolic complications 10 y postpartum in premenopausal Chilean women...

The power of lifestyle as medicine was perceived thousands of years ago. There is now consistent and compelling science to support the important influence of lifestyle on health. Approximately 80% of chronic disease and premature death could be prevented by not smoking, being physically active, and adhering to a healthful dietary pattern. Cardiovascular disease, diabetes, stroke, dementia, and cancer are all influenced by lifestyle choices. Despite the ample evidence about what behaviors promote health, confusion still prevails among the general population...

Autophagy is a catabolic degradation system used to destroy and recycle the unnecessary or damaged components of a cell. Autophagy is present at a basal level in all mammals and is regulated by some conditions, such as oxidative stress, starvation or hypoxia. In aged tissues, increased but also decreased expression of autophagy-specific proteins, Beclin 1, LC3, Atg5 and Atg7 has been reported. Likewise, it could be shown that the lifespan of yeast, nematodes and flies is prolonged by pharmacologically stimulated autophagy using exogenous administered spermidine...

Non-alcoholic fatty liver disease (NAFLD), the most common liver disease, is characterized by accumulation of fat (>5% of the liver tissue), in the absence of alcohol abuse or other chronic liver diseases. It is closely related to the epidemic of obesity, metabolic syndrome or type 2 diabetes mellitus (T2DM). NAFLD can cause liver inflammation and progress to non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis or hepatocellular cancer (HCC). Nevertheless, cardiovascular disease (CVD) is the most common cause of death in NAFLD/NASH patients...

Type 2 diabetes mellitus (T2DM) has been considered to be a risk factor for numerous human cancers. Hyperglycemia is one of the most direct internal environmental changes for patients with T2DM. Increasing evidence reveals that a high concentration of glucose can promote tumor progression, while its role for migration and invasion of invasive ductal breast carcinoma (IDBC) cells remains unclear. In the present study, it was demonstrated that IDBC patients with T2DM suffered an increased tumor size and more frequent lymphatic and distant metastasis compared with those without T2DM (P<0...

Bisphenol A (BPA), an endocrine disrupter, is widely used to make chemicals for polycarbonate, plastics, beverage containers, epoxy resins, and cash register receipts. BPA is one of the known xenoestrogens, which have weak estrogenic activity and cause obesity, diabetes, breast cancer, and reproductive disorders. Even though the concentration level of metabolomes in hair is usually lower than that in urine and blood, there are several reasons why we chose to use hair samples. First, the sampling procedure of hairs is simple...

Apolipoprotein C-III (apoC-III) is a potential novel biomarker that may play an important role in the pathogenesis of diabetes, particularly when present on high-density lipoprotein (HDL). In a case-cohort design among 3,101 non-cases and 434 incident diabetes cases occurring before 2007 in the Danish Diet, Cancer, and Health study, we examined associations of baseline (1993-1997) plasma concentrations of apoC-III and subspecies of HDL defined by the presence or absence of apoC-III with risk of diabetes using Cox regression...

Adipose tissue (AT) has a central role in obesity-related metabolic imbalance through the dysregulated production of cytokines and adipokines. In addition to its known risk for cardiovascular disease and diabetes, obesity is also a major risk for cancer. We investigated the impact of obesity for the expression of survivin, an antiapoptotic protein upregulated by adipokines and a diagnostic biomarker of tumor onset and recurrence. In a cross-sectional study of 111 subjects classified by body mass index, circulating levels of survivin and gene expression in subcutaneous AT were significantly higher in obese patients and positively correlated with leptin...

BACKGROUND: Advances in cancer immunotherapy have generated encouraging results in multiple malignancies refractory to standard chemotherapies. As the use of immune checkpoint inhibitors (ICI) proliferates, the incidence of autoimmune side effects associated with these agents, termed immune related adverse events (irAE), is expected to increase. The frequency of significant irAE in ICI treated patients is about 10-20% and early recognition is critical to prevent serious morbidity and even mortality...

Work in repeated changing shifts, in general, and night-shifts, in particular, is considered a necessity, encompassing many professions, among them physicians and nurses. This type of work has been shown to adversely affect the normal function of the human body circadian rhythm. This negative influence in turn, is considered to increase characteristic types of morbidity such as metabolic syndrome, type 2 diabetes and increased rate of cardiovascular morbidity. Women working in night-shifts in particular, have been found to face increased rates of breast cancer, as well as menstrual disturbances and decreased fertility...

A diet high in phytochemical-rich plant foods is associated with reducing the risk of chronic diseases such as cardiovascular and neurodegenerative diseases, obesity, diabetes and cancer. Oxidative stress and inflammation (OSI) is the common component underlying these chronic diseases. Whilst the positive health effects of phytochemicals and their metabolites have been demonstrated to regulate OSI, the timing and absorption for best effect is not well understood. We developed a model to predict the time to achieve maximal plasma concentration (Tmax) of phytochemicals in fruits and vegetables...

Lung cancer is the most fatal malignancy worldwide, in part, due to high resistance to cytotoxic therapy. There is need for effective chemo-radio-sensitizers in lung cancer. In recent years, we began to understand the modulation of metabolism in cancer and its importance in tumor progression and survival after cytotoxic therapy. The activity of biosynthetic pathways, driven by the Growth Factor Receptor/Ras/PI3k/Akt/mTOR pathway, is balanced by the energy stress sensor pathway of LKB1/AMPK/p53. AMPK responds both to metabolic and genotoxic stress...
