Trans-Scirpusin A (TSA) is a resveratrol oligomer found in Borassus flabellifer L. We found that TSA inhibited the growth of colorectal cancer Her2/CT26 cells in vivo in mice. Although some cytotoxic T lymphocytes (CTLs) were induced against the tumor-associated antigen Her2, TSA treatment did not significantly increase the level of Her2-specific CTL response compared to that with vehicle treatment. However, there was a significant increase in the level of TNF-α mRNA in tumor tissue and Her2-specific Ab (antibody) production...

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD), the most common chronic liver disease, is the leading cause of cryptogenic cirrhosis and has consistently been implicated in related metabolic disorders, such as dyslipidemia and type 2 diabetes (T2D). However, the pathogenesis of NAFLD remains to be elucidated, and no established therapeutic regimens for treating NAFLD exist. Adenosine monophosphate (AMP)-activated protein kinase (AMPK), the main cellular energy sensor, has been implicated as a key regulator of hepatic lipid and glucose metabolism...

High levels of circulating low-density lipoproteins (LDL, plasma proteins that carry cholesterol and triglycerides) are associated with type 2 diabetes, arteriosclerosis, obesity and hyperlipidemia. In the heart, the accumulation of oxidized low-density lipoprotein (Ox-LDL) has been proposed to play a role in the development of cardiovascular disease. We obtain cholesterol from animals and animal-derived foods such as milk, eggs and cheese. In previous studies, the ratio of low-density lipoprotein (LDL) and high-density lipoprotein (HDL) was shown to be important for our health...

In addition to their prominent roles in the control of reproduction, estrogens are important modulators of energy balance, as evident in conditions of deficiency of estrogens, which are characterized by increased feeding and decreased energy expenditure, leading to obesity. AMP-activated protein kinase (AMPK) is a ubiquitous cellular energy gauge that is activated under conditions of low energy, increasing energy production and reducing energy wasting. Centrally, the AMPK pathway is a canonical route regulating energy homeostasis, by integrating peripheral signals, such as hormones and metabolites, with neuronal networks...

Resveratrol, an edible polyphenolic phytoalexin, improves endothelial dysfunction and attenuates inflammation. However, the mechanisms have not been thoroughly elucidated. Therefore, we investigated the molecular basis of the effects of resveratrol on TNF-α-induced ICAM-1 expression in HUVECs. The resveratrol treatment significantly attenuated the TNF-α-induced ICAM-1 expression. The inhibition of p38 phosphorylation mediated the reduction in ICAM-1 expression caused by resveratrol. Resveratrol also decreased TNF-α-induced IκB phosphorylation and the phosphorylation, acetylation, and translocation of NF-κB p65...

Hypertension is associated with aberrant structure and mechanical properties of resistance arteries. We determined the effects of resveratrol, a non-flavonoid polyphenol found in foods such as red grapes, and structurally-similar analogues (pterostilbene and gnetol) on systolic blood pressure (SBP) and resistance arteries from the spontaneously hypertensive heart failure (SHHF) rat. SBP was elevated in 17-week-old SHHF vs. Sprague-Dawley rats (normotensive control; 194 ± 3 vs. 142 ± 6 mmHg, p < 0.01) and was unaffected by resveratrol, pterostilbene, or gnetol (2...

Spinal cord injury (SCI) is a devastating condition with few effective treatments. Resveratrol, a polyphenolic compound, has exhibited neuroprotective effects in many neurodegenerative diseases. However, the explicit effect and mechanism of resveratrol on SCI is still unclear. Adenosine 5' monophosphate-activated protein kinase (AMPK) and Sirtuin 1 (SIRT1), the downstream protein, play key roles in metabolizing of energy, resisting of resistance, and cellular protein homeostasis. In this study, we determined the effects of resveratrol on SCI and their potential relationship with SIRT1/AMPK signaling pathway, autophagy and apoptosis...

We have recently reported P21-activated kinase 2 (PAK2), a serine/threonine kinase as a negative regulator of neuronal glucose uptake and insulin sensitivity. Resveratrol (RSV), a natural polyphenol with anti-oxidative, anti-inflammatory and anti-diabetic properties, regulates PAK2 activity in HepG2 and ESC-B5 cell apoptosis. However, regulation of PAK2 by RSV in neuronal insulin signaling pathway, if any, is still unknown. In the present study, RSV treatment significantly increased PAK2 activity under insulin-sensitive and insulin-resistant condition, along with a marked decrease in glucose uptake in differentiated N2A cells...

Resveratrol is known to be an effective chemo-preventive phytochemical against multiple tumor cells. However, the increasing drug resistance avoids the cancer treatment in oral cavity cancer. In this study, we investigated the oral antitumor activity of resveratrol and its mechanism in cisplatin-resistant human oral cancer CAR cells. Our results demonstrated that resveratrol had an extremely low toxicity in normal oral cells and provoked autophagic cell death to form acidic vesicular organelles (AVOs) and autophagic vacuoles in CAR cells by acridine orange (AO) and monodansylcadaverine (MDC) staining...

OBJECTIVES: Cerebral ischemia is a neurological condition in which energetics and oxidative stress are dysregulated. Resveratrol is a stilbene with potent pharmacological effects associated with its antioxidant properties. In the brain, resveratrol produces protective responses against ischemia, decreases infarct volume and improves neurological function. Adenosine monophosphate-activated protein kinase (AMPK) is a cellular sensor that acts as a switch to initiate adaptive changes in response to fluctuations in energy metabolism...

Stilbenoids are bioactive polyphenols, and resveratrol (trans-3,5,40-trihydroxystilbene) is a representative stilbenoid that reportedly exerts cardioprotective actions. As resveratrol exhibits low oral bioavailability, we turned our attention to other stilbenoid compounds with a history of medicinal use and/or improved bioavailability. We determined the effects of gnetol (trans-3,5,20,60-tetrahydroxystilbene) and pterostilbene (trans-3,5-dimethoxy-40-hydroxystilbene) on cardiac hypertrophy. In vitro, gnetol and pterostilbene prevented endothelin-1-induced indicators of cardiomyocyte hypertrophy including cell enlargement and protein synthesis...

As a sugar additive, fructose is widely used in processed foods and beverages. Excessive fructose consumption can cause hepatic steatosis and dyslipidemia, leading to the development of metabolic syndrome. Recent research revealed that fructose-induced nonalcoholic fatty liver disease (NAFLD) is related to several pathological processes, including: (1) augmenting lipogenesis; (2) leading to mitochondrial dysfunction; (3) stimulating the activation of inflammatory pathways; and (4) causing insulin resistance...

Intrauterine growth restriction (IUGR) may predispose offspring to an increased susceptibility of developing cardiovascular disease (CVD) in adult life. The window of opportunity to treat later life CVD programmed in fetal life is critical. The aim of this study was to identify the effect of resveratrol treatment of IUGR offspring at a time of known CV dysfunction. Sprague-Dawley male and female rat offspring who experienced normoxia (21% O2; control) or hypoxia (11% O2; IUGR) in utero were fed a high-fat (HF) diet (3-21 weeks of age) or a HF diet (3-21 weeks of age) supplemented with resveratrol from 13 to 21 weeks of age...

Inflammation and oxidative stress (OS) are key points in age progression. Both processes impact negatively in cognition and in brain functions. Resveratrol (RV) has been postulated as a potent antioxidant natural compound, with rejuvenating properties. Inducing a metabolic stress by high-fat (HF) diet in aged C56/BL6 (24 months) led to cognitive disturbances compared with control age mated and with young mice. These changes were prevented by RV. Molecular determinations demonstrated a significant increase in some inflammatory parameters (TNF-α, Cxcl10, IL-1, IL-6, and Ccl3) in old mice, but slight changes in OS machinery...

Growing evidence indicates that in diabetes, high glucose concentrations affect podocyte metabolism and function. The crucial pathological feature of type 2 diabetes mellitus and metabolic syndrome is insulin resistance, often developed as a result of dysregulation of nutrient-responsible systems and disturbance of cellular homeostasis under diabetic conditions. Here, we report the involvement of the reciprocal interplay between deacetylase SIRT1 and protein kinase AMPK in podocyte high glucose-induced abolition of insulin-dependent glucose uptake, manifesting insulin resistance...
