Sesamol, a nutritional component from sesame, possesses antioxidant, lipid lowering and antidepressant activities. Nonetheless, few studies report its effects on high-energy-dense diet-induced cognitive loss. The present research aimed to elucidate the action of sesamol on high-fat and high-fructose (HFFD) "western"-diet-induced central nervous system insulin resistance and learning and memory impairment, and further determined the possible underlying mechanism. 3 month-old C57BL/6J mice were divided into 3 groups with/without sesamol in the drinking water (0...

Progressive pancreatic β cell failure underlies the transition of impaired glucose tolerance to overt diabetes; endoplasmic reticulum (ER) stress expedites β cell failure in this situation. ER stress can be elicited by lipotoxicity and an increased demand for insulin in diabetes. We previously reported that the lipid droplet protein perilipin 2 (PLIN2) modulates lipid homeostasis in the liver. Here, we show that PLIN2 modulates the unfolded protein response (UPR) and ER stress in pancreatic β cells. PLIN2 expression goes up when β cells are exposed to a lipid load or to chemical ER stress inducers...

Serine hydrolases are a large family of multifunctional enzymes known to influence obesity. Here, we performed activity-based protein profiling to assess the functional level of serine hydrolases in liver biopsies from lean and obese humans in order to gain mechanistic insight into the pathophysiology of metabolic disease. We identified reduced hepatic activity of carboxylesterase 2 (CES2) and arylacetamide deacetylase (AADAC) in human obesity. In primary human hepatocytes, CES2 knockdown impaired glucose storage and lipid oxidation...

Cholesterol is important for normal brain function. The brain synthesizes its own cholesterol, presumably in astrocytes. We have previously shown that diabetes results in decreased brain cholesterol synthesis by a reduction in sterol regulatory element-binding protein 2 (SREBP2)-regulated transcription. Here we show that coculture of control astrocytes with neurons enhances neurite outgrowth, and this is reduced with SREBP2 knockdown astrocytes. In vivo, mice with knockout of SREBP2 in astrocytes have impaired brain development and behavioral and motor defects...

Insulin and IGF-1 receptors (IR and IGF1R) are major regulators of metabolism and cell growth throughout the body, however, their roles in the intestine remain controversial. Here we show that genetic ablation of the IR or IGF1R in intestinal epithelial cells of mice does not impair intestinal growth or development or the composition of the gut microbiome. However, loss of IR alters intestinal epithelial gene expression, especially in pathways related to glucose uptake and metabolism. More importantly, loss of IR reduces intestinal glucose uptake...

The association of pathogenic viruses with obesity has now been well-known in both human and animals. Globally, human obesity has become a serious problem leading to the emergence of multiple life-threatening diseases. Adenoviruses contribute a significant role in the induction of obesity by affecting various pathways. Due to impaired immunity, obese individuals are more prone to nosocomial infections leading to complications of obesity. In contrast, several other important factors contributing to human obesity are known...

BACKGROUND: Acute ingestion of bitter melon (BM) has been shown to suppress the postprandial glycemic response in diabetics, but its impact on glucose regulation among individuals with impaired glucose tolerance is unclear. Moreover, one's glucose tolerance level may influence the effectiveness of BM. This study aimed to examine the acute effects of a beverage containing BM extract on blood glucose regulation during an oral glucose tolerance test (OGTT) among prediabetics. METHODS: Ten prediabetic adults completed two OGTTs-glucose only (D2) and glucose+BM (D3)...

Obese and diabetic individuals are at increased risk for impairments in diastolic relaxation and heart failure with preserved ejection fraction. The impairments in diastolic relaxation are especially pronounced in obese and diabetic women and predict future cardiovascular disease (CVD) events in this population. Recent clinical data suggest sodium glucose transporter-2 (SGLT2) inhibition reduces CVD events in diabetic individuals, but the mechanisms of this CVD protection are unknown. To determine whether targeting SGLT2 improves diastolic relaxation, we utilized empagliflozin (EMPA) in female db/db mice...

: Glucose-dependent insulinotropic polypeptide (GIP) beyond its insulinotropic effects may regulate post-prandial lipid metabolism. While the insulinotropic action of GIP is known to be impaired in type 2 diabetes mellitus (T2DM), its adipogenic effect is unknown. We hypothesised GIP is anabolic in human subcutaneous adipose tissue (SAT) promoting triacylglycerol (TAG) deposition through re-esterification of non-esterified fatty acids (NEFA) and this effect may differ according to obesity status or glucose tolerance...

Objectives: Omentin-1, an adipocytokine that increases the insulin sensitivity, has been determined to be reduced in patients with insulin resistance, impaired glucose tolerance, and Type-2 diabetes mellitus. In this study, we have investigated the alterations in Omentin-1 levels with the blood glucose regulation in diabetic patients having poor glycemic control. By this way, we aimed to determine the role of Omentin-1 as a marker in follow-up and monitoring progression of diabetes. Methods: Totally 58 patients with type 2 diabetes mellitus, older than 18 years of age who were having poor glycemic control (HbA1c≥9) were included in this study...

Maternal undernutrition is linked with an elevated risk of diabetes mellitus in offspring regardless of the postnatal dietary status. This is also found in maternal micro-nutrition deficiency, especial chromium which is a key glucose regulator. We investigated whether maternal chromium restriction contributes to the development of diabetes in offspring by affecting DNA methylation status in liver tissue. After being mated with control males, female weanling 8-week-old C57BL mice were fed a control diet (CON, 1...

Defective glucose-stimulated insulin secretion (GSIS) induced by chronic exposure to fatty acids is a hallmark of type 2 diabetes (T2D). Interleukin-22 (IL-22) has been shown to exert beneficial effects on insulin secretion and to protect pancreatic β-cells from stress. Moreover, uncoupling protein-2 (UCP-2) plays a central role in the regulation of GSIS and β-cell dysfunction, whereas the role of UCP-2 in IL-22-enhanced glycemic control under conditions of lipotoxicity remains unclear. In this present study, we investigated the effects of IL-22 on rat insulin-secreting cells (INS-1 cells) and the mechanisms that underlie IL-22 and lipotoxicity-impaired GSIS in vitro...

Maintenance of glucose homeostasis is essential for normal physiology. Deviation from normal glucose levels, in either direction, increases susceptibility to serious medical complications such as hypoglycemia or diabetes. Maintenance of glucose homeostasis is achieved via functional interactions amongst various organs, liver, skeletal muscle, adipose tissue, brain and the endocrine pancreas. The liver is the primary site for endogenous glucose production, especially during states of prolonged fasting. However, enhanced gluconeogenesis is also a signature feature of type 2 diabetes (T2D)...

Gomisin N (GN) is a physiological lignan derived from Schisandra chinensis. In the present study, we investigated the inhibitory effects of GN on differentiation of 3T3-L1 preadipocytes and the anti-obesity effects of GN in high-fat diet (HFD)-induced obese mice. Incubation with GN significantly inhibited the differentiation of 3T3-L1 preadipocytes in a dose-dependent manner. This inhibitory effect primarily occurred at an early adipogenic stage through impairment of mitotic clonal expansion (MCE) caused by cell cycle arrest at the G1/S phase transition...

AIM: Microangiopathy due to endothelial dysfunction is a major contributing factor to the development of diabetes-induced cardiovascular disease (CVD). Dysregulation of endothelial-specific microRNAs (miRs) is correlated with impaired angiogenesis and cell survival. We investigated the profile of two angiomiRs, miR-126, and miR-132, in the plasma of type 2 diabetic individuals without any known history of CVD as well as in the cardiac tissues collected from diabetics undergoing cardiac surgery...

BACKGROUND: The importance of dyslipidemia is well recognized in the context of both risk factor for acute pancreatitis and prognostic factor for its in-hospital outcomes. With a growing appreciation of post-pancreatitis diabetes mellitus, there is a need to catalogue changes in lipid metabolism after hospitalization due to an acute pancreatitis attack and their associations with glucose metabolism. OBJECTIVE: To investigate lipid metabolism in patients with impaired glucose homeostasis following acute pancreatitis...

Arabidopsis thaliana At4g17830 codes for a protein showing sequence similarity with the Escherichia coli N-acetylornithine deacetylase (EcArgE), an enzyme implicated in the linear ornithine (Orn) biosynthetic pathway. In plants, N-acetylornithine deacetylase (NAOD) activity has yet to be demonstrated; however, At4g17830-silenced and mutant (atnaod) plants display an impaired reproductive phenotype and altered foliar levels of Orn and polyamines (PAs). Here, we showed the direct connection between At4g17830 function and Orn biosynthesis, demonstrating biochemically that At4g17830 codes for a NAOD...

Male sex predisposes to many kidney diseases. Considering that androgens exert deleterious effects in a variety of cell types within kidney, we hypothesized that dihydrotestosterone (DHT) would alter the biology of the renal tubular cell by inducing changes in the proteome. We employed stable isotope labeling with amino acids (SILAC) in an indirect spike-in fashion to accurately quantify the proteome in DHT- and 17β-estradiol (EST)-treated human proximal tubular epithelial cells (PTEC). Of the 5043 quantified proteins, 76 were differentially regulated...
