Abstract
Trans-Resveratrol (3, 5, 4'-trihydroxystilbene) is a naturally occurring polyphenol easily oxidizable and extremely photosensitive with a short biological half-life that must be encapsulated to maintain its beneficial properties on the human body. The aim of this work is to increase the amount of resveratrol encapsulated using concentrated double water-in-oil-in-water (W1/O/W2) emulsions, making these systems more interesting as ingredient for functional food products and/or pharmaceutical formulations. The concentration of the inner emulsion (W1/O) for several external (W1O/W2) ratios was optimized in terms of encapsulation efficiency (EE), colloidal stability and rheological behaviour. W1/O emulsions formulated with ratios of 30/70 and 40/60 were used to obtain double emulsions (with ratios of 20/80 up to 80/20 of W1O/W2). Trans-Resveratrol EE increased up to 90 % when the most concentrated double emulsions were prepared for both W1/O ratios tested. The maximum resveratrol concentrations on double emulsions were 10.8 mg/L and 14.4 mg/L when 30/70 and 40/60 of W1/O ratios were used, respectively. However, longer time stability was found for double high internal phase emulsions (W1O/W2) with a ratio of 30/70 of W1/O. The double emulsion formulated with a 80/20 W1O/W2 volumetric ratio together with 30/70 of W1/O seems suitable to be used as ingredient for pharmaceutical and food devices/products due to its high colloidal stability, clearly pseudoplastic and elastic behaviour, high EE and large trans-Resveratrol carrier capacity.

Abstract
Apolipoproteins are critical structural and functional components of lipoproteins, which are large supramolecular assemblies composed predominantly of lipids and proteins, and other biomolecules such as nucleic acids. A signature feature of apolipoproteins is the preponderance of amphipathic α-helical motifs that dictate their ability to make extensive non-covalent inter- or intra-molecular helix-helix interactions in lipid-free states or helix-lipid interactions with hydrophobic biomolecules in lipid-associated states. This review focuses on the latter ability of apolipoproteins, which has been capitalized on to reconstitute synthetic nanoscale binary/ternary lipoprotein complexes composed of apolipoproteins/peptides and lipids that mimic native high-density lipoproteins (HDLs) with the goal to transport drugs. It traces the historical development of our understanding of these nanostructures and how the cholesterol accepting property of HDL has been reconfigured to develop them as drug-loading platforms. The review provides the structural perspective of these platforms with different types of apolipoproteins and an overview of their synthesis. It also examines the cargo that have been loaded into the core for therapeutic and imaging purposes. Finally, it lays out the merits and challenges associated with apolipoprotein-based nanostructures with a future perspective calling for a need to develop "zip-code"-based delivery for therapeutic and diagnostic applications.

Abstract
Resveratrol is a well-known wine constituent. Its concentration can vary according to the cultivar choice and the winemaking process. Due to its phenolic structure, resveratrol could be transformed under high temperature or oxidative conditions, leading to the formation of various derivatives including oligomers. Hence, the goal of this study is to investigate the presence of these derivatives in wine. In the first stage, hemisynthesis of oligomeric stilbenes was achieved from resveratrol in ethanol by oxidative coupling using metals. Four de novo synthetized resveratrol derivatives were identified by MS and NMR spectroscopy including two new molecules, oxistilbenin F and oxistilbenin G. In the second stage, analysis of red wine after heat treatment by LC-MS confirmed the presence of some of these compounds in wine. Finally, the anti-inflammatory effects of the compounds were evaluated by studying their ability to prevent lipopolysaccharide (LPS)-induced upregulation of nitric oxide (NO) and reactive oxygen species (ROS) production in RAW 264.7 macrophage cell line.

Abstract
Myotonic dystrophy type 1 (DM1) is a spliceopathy related to the mis-splicing of several genes caused by sequestration of nuclear transcriptional RNA-binding factors from non-coding CUG repeats of DMPK pre-mRNAs. Dysregulation of ryanodine receptor 1 (RYR1), sarcoplasmatic/endoplasmatic Ca2+-ATPase (SERCA) and α1S subunit of voltage-gated Ca2+ channels (Cav1.1) is related to Ca2+ homeostasis and excitation-contraction coupling impairment. Though no pharmacological treatment for DM1 exists, aberrant splicing correction represents one major therapeutic target for this disease. Resveratrol (RES, 3,5,4′-trihydroxy-trans-stilbene) is a promising pharmacological tools for DM1 treatment for its ability to directly bind the DNA and RNA influencing gene expression and alternative splicing. Herein, we analyzed the therapeutic effects of RES in DM1 myotubes in a pilot study including cultured myotubes from two DM1 patients and two healthy controls. Our results indicated that RES treatment corrected the aberrant splicing of RYR1, and this event appeared associated with restoring of depolarization-induced Ca2+ release from RYR1 dependent on the electro-mechanical coupling between RYR1 and Cav1.1. Interestingly, immunoblotting studies showed that RES treatment was associated with a reduction in the levels of CUGBP Elav-like family member 1, while RYR1, Cav1.1 and SERCA1 protein levels were unchanged. Finally, RES treatment did not induce any major changes either in the amount of ribonuclear foci or sequestration of muscleblind-like splicing regulator 1. Overall, the results of this pilot study would support RES as an attractive compound for future clinical trials in DM1. Ethical approval was obtained from the Ethical Committee of IRCCS Fondazione Policlinico Universitario A. Gemelli, Rome, Italy (rs9879/14) on May 20, 2014.

Abstract
Glycerol is a co-solvent for water extraction that has been shown to be highly effective for obtaining polyphenol extracts under atmospheric conditions. However, its efficacy under subcritical conditions has not yet been studied. We assessed different water-glycerol mixtures (15%, 32.5%, and 50%) in a hot pressurized liquid extraction system (HPLE: 10 MPa) at 90 °C, 120 °C, and 150 °C to obtain extracts of low molecular weight polyphenols from Carménère grape pomace. Under the same extraction conditions, glycerol as a co-solvent achieved significantly higher yields in polyphenols than ethanol. Optimal extraction conditions were 150 °C, with 32.5% glycerol for flavonols and 50% for flavanols, stilbenes, and phenolic acids. Considering gallic acid as a model molecule, computational chemistry calculations were applied to explain some unusual extraction outcomes. Furthermore, glycerol, methanol, ethanol, and ethylene glycol were studied to establish an incipient structure-property relationship. The high extraction yields of gallic acid obtained with water and glycerol solvent mixtures can be explained not only by the additional hydrogen bonds between glycerol and gallic acid as compared with the other alcohols, but also because the third hydroxyl group allows the formation of a three-centered hydrogen bond, which intensifies the strongest glycerol and gallic acid hydrogen bond. The above occurs both in neutral and deprotonated gallic acid. Consequently, glycerol confers to the extraction solvent a higher solvation energy of polyphenols than ethanol.

Abstract
One of the major risk factors for asthma development is exposure to environmental allergens. House dust mites (HDM) can induce DNA damage, resulting in asthma. Resveratrol (RES) produced by several plants, has anti‑apoptotic properties and may affect a variety of biological processes. The aim of the present study was to investigate the protective role of RES against apoptosis in bronchial epithelial cells. C57BL/6J mice treated with HDM exhibited high levels of cell apoptosis, while RES significantly reversed this process. Induced DNA damage was more severe in the HDM group vs. the HDM combined with RES group. This result was confirmed by immunostaining and western blot analysis of the protein expression of the DNA damage‑related gene γH2AX, which was highly induced by HDM. In addition, treatment with RES protected bronchial epithelial cells exposed to HDM from DNA damage. RES decreases reactive oxygen species levels to inhibit oxidative DNA damage in bronchial epithelial cells. Furthermore, compared with the HDM group, induced cell apoptosis could be attenuated by RES in the group of combined treatment with RES and HDM. A DNA repair inhibitor augmented DNA damage and apoptosis in bronchial epithelial cells, whereas RES significantly attenuated cell apoptosis through inhibiting DNA damage.

Abstract
Resveratrol, a phytophenol, is a commonly used equine nutraceutical supplement touted to exert anti-inflammatory effects. The effect of orally administered resveratrol on tumor necrosis factor (TNF), interleukin-1β (IL-1β), leukocyte phagocytic activity or oxidative burst function have not been reported in horses. The objective of this study was to determine the effects of a commercially available, orally administered resveratrol product on innate immune functions in healthy adult horses. Whole blood was collected from 12 horses prior to and following 3 weeks of treatment with either the manufacturer’s recommended dose of resveratrol or placebo. Phagocytosis, oxidative burst and pathogen associated molecular pattern (PAMP) motif-stimulated leukocyte production of TNF and IL-1β were compared pre- and post-treatment between treatment groups. Phagocytosis and oxidative burst capacity were evaluated via flow cytometry. Tumor necrosis factor and IL-1β were measured using cytotoxicity and ELISA assays, respectively. There were no significant differences in phagocytosis, oxidative burst or stimulated TNF or IL-1β production between resveratrol and placebo treatment groups. Orally administered resveratrol at a routinely recommended dose for a duration of 3 weeks did not significantly affect phagocytic activity, oxidative burst function or PAMP-stimulated leukocyte cytokine production.

Abstract
Topoisomerases are enzymes that catalyze DNA unwinding and scissions to resolve topological entanglements possibly arising during DNA replication/transcription. Chemicals which disrupt or inhibit topoisomerase-mediated DNA unwinding can induce breaks that subsequently lead to programmed cell death. Herein we perform experiments guided by the following considerations. First, topoisomerase 1 initiates DNA cleavage utilizing the hydroxyl group of tyrosine 723 on its catalytic site as a nucleophile to attack the electrophilic phosphate on the DNA sugar-phosphate backbone. Secondly, the grape polyphenol resveratrol displays both topoisomerase inhibitory and Cu2+-dependent DNA-cutting activities, which contribute to its DNA replication/transcription inhibitory/anti-tumorigenic effects. Lastly, resveratrol contains a tyrosine-like phenolic ring; thus, upon binding to DNA whether resveratrol could act as a tyrosine mimetic to unwind and cut DNA via its hydroxyl groups warrants investigation. Polyphenol-DNA interactions (PDIs) were investigated using UV-visible spectral analysis; additionally, PDI mediated DNA changes were further analyzed by agarose gel electrophoresis using 3 supercoiled plasmid DNAs (pBR322, pSJ3, pHOT-1) as substrates. Resveratrol mediates time- and temperature-dependent, Cu2+-independent, non-enzymatic cleavage of supercoiled plasmid DNA into open, circular DNA products. Varying degree of unwinding of supercoiled DNA nucleolytic activity was also observed with other polyphenols including, piceatannol, quercetin, myricetin and EGCG. Interestingly, we found that piceatannol mediated Cu2+-independent DNA-cleavage activity was abolished by EDTA. The PDI-mediated nucleolytic cleavage of supercoiled DNA reported herein shows that polyphenolic phytochemicals display genome-active, nuclear effects by directly targeting the DNA topology which in turn could impact macromolecular processes associated with faithful replication and transmission of genetic information.

Abstract
Cataracts, one of the leading causes of preventable blindness worldwide, refers to lens degradation that is characterized by clouding, with consequent blurry vision. As life expectancies improve, the number of people affected with cataracts is predicted to increase worldwide, especially in low-income nations with limited access to surgery. Although cataract surgery is considered safe, it is associated with some complications such as retinal detachment, warranting a search for cheap, pharmacological alternatives to the management of this ocular disease. The lens is richly endowed with a complex system of non-enzymatic and enzymatic antioxidants which scavenge reactive oxygen species to preserve lens proteins. Depletion and/or failure in this primary antioxidant defense system contributes to the damage observed in lenticular molecules and their repair mechanisms, ultimately causing cataracts. Several attempts have been made to counteract experimentally induced cataract using in vitro, ex vivo, and in vivo techniques. The majority of the anti-cataract compounds tested, including plant extracts and naturally-occurring compounds, lies in their antioxidant and/or free radical scavenging and/or anti-inflammatory propensity. In addition to providing an overview of the pathophysiology of cataracts, this review focuses on the role of various categories of natural and synthetic compounds on experimentally-induced cataracts.

Abstract
Scavenger receptor class B type I (SR-BI) protein is an integral membrane glycoprotein. SR-BI is emerging as a multifunctional protein, which regulates autophagy, efferocytosis, cell survival and inflammation. It is well known that SR-BI plays a critical role in lipoprotein metabolism by mediating cholesteryl esters selective uptake and the bi-directional flux of free cholesterol. Recently, SR-BI has also been identified as a potential marker for cancer diagnosis, prognosis, or even a treatment target. Natural products are a promising source for the discovery of new drug leads. Multiple natural products were identified to regulate SR-BI protein expression. There are still a number of challenges in modulating SR-BI expression in cancer and in using natural products for modulation of such protein expression. In this review, our purpose is to discuss the relationship between SR-BI protein and cancer, and the molecular mechanisms regulating SR-BI expression, as well as to provide an overview of natural products that regulate SR-BI expression.

Abstract
New strategies to block the immune evasion activity of programmed death ligand-1 (PD-L1) are urgently needed. When exploring the PD-L1-targeted effects of mechanistically diverse metabolism-targeting drugs, exposure to the dietary polyphenol resveratrol (RSV) revealed its differential capacity to generate a distinct PD-L1 electrophoretic migration pattern. Using biochemical assays, computer-aided docking/molecular dynamics simulations, and fluorescence microscopy, we found that RSV can operate as a direct inhibitor of glyco-PD-L1-processing enzymes (α-glucosidase/α-mannosidase) that modulate N-linked glycan decoration of PD-L1, thereby promoting the endoplasmic reticulum retention of a mannose-rich, abnormally glycosylated form of PD-L1. RSV was also predicted to interact with the inner surface of PD-L1 involved in the interaction with PD-1, almost perfectly occupying the target space of the small compound BMS-202 that binds to and induces dimerization of PD-L1. The ability of RSV to directly target PD-L1 interferes with its stability and trafficking, ultimately impeding its targeting to the cancer cell plasma membrane. Impedance-based real-time cell analysis (xCELLigence) showed that cytotoxic T-lymphocyte activity was notably exacerbated when cancer cells were previously exposed to RSV. This unforeseen immunomodulating mechanism of RSV might illuminate new approaches to restore T-cell function by targeting the PD-1/PD-L1 immunologic checkpoint with natural polyphenols.

Antimicrobial activity of resveratrol-derived monomers and dimers against foodborne pathogens. Sci Rep 2019; 9:19525.

Abstract
Plant polyphenolic compounds are considered a promising source for new antibacterial agents. In this study, we evaluated the antimicrobial activity of a collection of resveratrol-derived monomers and dimers screened as single molecules against a panel of nine foodborne pathogens. The results demonstrated that two monomers (i.e., pterostilbene 2 and (E)-3-hydroxy-4′,5-dimethoxystilbene 9) and three dimers (i.e., δ-viniferin 10, viniferifuran 14 and dehydro-δ-viniferin 15) were endowed with significant antibacterial activity against gram-positive bacteria. The exposure of gram-positive foodborne pathogens to 100 µg/mL of 2, 9 and 15 induced severe cell membrane damage, resulting in the disruption of the phospholipid bilayer. The most promising dimeric compound, dehydro-δ-viniferin 15, was tested against Listeria monocytogenes, resulting in a loss of cultivability, viability and cell membrane potential. TEM analysis revealed grave morphological modifications on the cell membrane and leakage of intracellular content, confirming that the cell membrane was the principal biological target of the tested derivative.

Tumor PD-L1 Induction by Resveratrol/Piceatannol May Function as a Search, Enhance, and Engage ("SEE") Signal to Facilitate the Elimination of "Cold, Non-Responsive" Low PD-L1-Expressing Tumors by PD-L1 Blockade. Int J Mol Sci 2019; 20:ijms20235969.

Abstract
Programmed cell death ligand 1 (PD-L1) is an immune regulatory protein that facilitates tumor escape from host immune surveillance. In the clinic, tumors with high level of PD-L1 have been used to identify patients who might respond favorably to treatment by anti-PD-L1 antibodies (PD-L1 blockade, PLB). Typically, a progression-free response of 9–20% to PLB has been observed, the basis for the low success rate is largely unknown. Recently, we show upregulation of PD-L1 in cancer cells by ≥IC50 supra-pharmacological dose of grape polyphenol resveratrol and piceatannol, alone and combined. Herein, we summarize recent published studies on the regulation of tumor PD-L1 by flavonoids and grape polyphenols. We hypothesize that the induced tumor PD-L1 by resveratrol and/or piceatannol may serve as a Search, Enhance, and Engage (“SEE”) signal to sensitize and augment the recognition and detection of low PD-L1-expressing “cold, non-responsive” tumors. The “SEE” strategy enhances the “visibility” of previously unidentified tumor cells for targeting and eventual eradication by the host antitumor activity. This strategy expands the selection criteria for patients with improved sensitivity and potential responsiveness when used in combination with PLB. The modulation of tumor PD-L1 by flavonoids or polyphenols is proposed to improve the response to PLB in low PD-L1 tumors.

Abstract
Aim: Oat protein-shellac nanoparticles (NPs) were developed as a delivery system for resveratrol to improve bioavailability. Materials & methods: The NPs were prepared from w/w emulsion followed by cold-gelation. In vitro release and cell uptake mechanism of NPs were estimated by HPLC and confocal laser scanning microscopy. In vivo bioavailability and hepatoprotective activity of encapsulated resveratrol were studied using rat models. Results & conclusion: NPs (90-300 nm) protected resveratrol in gastric fluid, while allowing controlled release into small intestine in vitro. The optimized NPs showed improvement in resveratrol cell uptake and transport when compared with free resveratrol. NP-100S increased resveratrol bioavailability up to 72.4%, and the absorbed resveratrol effectively prevented CCl4-induced hepatotoxicity by attenuating oxidative stress.

Abstract
Resveratrol is a natural compound found in many plant species that has broad therapeutic benefits. Here, we investigated the effects of resveratrol on the replication of HSV-2. We found that resveratrol accelerated replication of HSV-2 and increased release of progeny virion. A time-of-addition study suggested that resveratrol worked primarily in the early stage of viral infection. Resveratrol regulated HSV-2 infection by increasing histone acetylation and activating NF-κB. In addition, inhibition of CDK9 activity restrained the promoting effect of resveratrol on HSV-2 infection. Altogether, our experiments revealed the regulatory effect of resveratrol and its mechanism of action on HSV-2 replication.

Abstract
Accumulation of stilbene phytoalexins stimulates resistance mechanisms against the grapevine fungus Uncinula necator. However, the defensive mechanisms triggered by stilbene synthase (STS) genes, remain largely unknown. Here, we report the function and molecular mechanism of the stilbene synthase gene VpSTS29/STS2 from Vitis pseudoreticulata in the regulation of plant responses to powdery mildew. Stilbene synthesis occurred mainly in root tips and mesophyll cells of transgenic grapevines via transport through the vascular bundles. Overexpression of VpSTS29/STS2 in Vitis vinifera increased the abundance of STSs in mesophyll tissue and resulted in the accumulation of biologically active resveratrol derivatives at the invasion site. Similarly, expression of VpSTS29/STS2 in Arabidopsis increased resistance to Golovinomyces cichoracearum. The VpSTS29/STS2-expressing Arabidopsis lines showed increased piceid accumulation together with more local hypersensitive reactions, inhibition of mycelial growth, and a reduced incidence of pathogens. Transcriptome profiling analyses demonstrated that VpSTS29/STS2-induced defences led to reprograming of global gene expression and activation of salicylic acid (SA) signalling, thus increasing expression of WRKY-MYB transcription factors and other defence response genes. We propose a model for resveratrol-mediated coordination of defence responses in which SA participates in a positive feedback loop.

Abstract
Noncommunicable diseases (NCDs) are considered to be the leading cause of death worldwide. Inadequate fruit and vegetable intake have been recognized as a risk factor for almost all NCDs (type 2 diabetes mellitus, cancer, and cardiovascular and neurodegenerative diseases). The main aim of this review is to examine the possible protective effect that fruit and vegetable consumption or their bioactive compounds may have on the development of NCDs such as atherosclerosis. The accumulated evidence on the protective effects of adequate consumption of fruits and vegetables in some cases, or the lack of evidence in others, are summarized in the present review. The main conclusion of this review is that well-designed, large-scale, long-term studies are needed to truly understand the role fruit and vegetable consumption or their bioactive compounds have in atherosclerosis.

Abstract
The prevalence of neurodegenerative disorders characterized by the loss of neuronal function is rapidly
increasing. The pathogenesis of the majority of these diseases is not entirely clear, but current evidence has
shown the possibility that autophagy, apoptosis, inflammation and oxidative stress are involved. The present
review summarizes the therapeutic effects of resveratrol on neurodegenerative disorders, based on the especially
molecular biology of these diseases. The PubMed, Cochrane, Web of Science and Scopus databases were
searched for studies published in English until March 30th, 2019 that contained data for the role of inflammation,
oxidative stress, angiogenesis and apoptosis in the neurodegenerative disorders. There are also studies documenting
the role of molecular processes in the progression of central nervous system diseases. Based on current evidence,
resveratrol has potential properties that may reduce cell damage due to inflammation. This polyphenol
affects cellular processes, including autophagy and the apoptosis cascade under stressful conditions. Current
evidence supports the beneficial effects of resveratrol on the therapy of neurodegenerative disorders.

Abstract
Background Thioacetamide (TAA), a class 2B-type carcinogen, is a potent toxicant. Toxicities caused by this compound in various tissues due to oxidative stress, increase of proinflammatory markers, and apoptosis have been reported; however, reports on kidney toxicity are negligible. Resveratrol (RSV), on the other hand, has demonstrated antioxidant and anti-inflammatory effects in different cases. Resveratrol's protective effects against TAA kidney toxicity were investigated in four rat groups. Methodology Four groups of rats were studied as follows (n = 8): control group, where rats were fed normal diet and water; TAA group, where rats received 0.3% TAA in water for two weeks; RSV group, where rats received 10 mg/kg body weight (bw) of RSV as oral suspension for two weeks; and treated group, where rats orally received 10 mg/kg bw RSV and simultaneously received 0.3% TAA for two weeks. Kidney homogenates from all groups were analyzed for cytokine release (IL-4, TNF-α, and IFN-γ) and oxidative stress (lipid peroxidation, catalase, and 8-OHdG). The serum of rats was analyzed for the quantification of renal function markers (blood urea nitrogen (BUN), creatinine, and creatine kinase). Result A significant increase in the renal function markers (BUN, 240%; creatinine, 187%; and creatine kinase, 117%), oxidative stress parameters (lipid peroxidation, 192% increase; catalase, 30.5% decrease), cytokines (IL-4, 120%; TNF-α, 129%; and IFN-γ, 133%), and DNA damage was observed in the TAA-treated group. All changes were significantly reversed in the group treated with RSV and TAA (P < 0.05) in combination, with no significant difference compared to the control group. Conclusion We conclude that resveratrol shows protection against TAA toxicity in rat kidney with respect to DNA damage, oxidative stress, renal function and cytokine release.

Abstract
Objective: Resveratrol (RV) is a polyphenol with antioxidant, anti-inflammatory and cardio-protective properties. Our objective was to investigate whether acute supplementation with high doses of RV would improve flow-mediated dilation (FMD) and oxygen consumption (VO2) kinetics in older coronary artery disease (CAD) patients. Design: We employed a placebo-controlled, single-blind, crossover design in which ten participants (aged 66.6 ± 7.8 years) received either RV or placebo (330 mg, 3× day-1) during three consecutive days plus additional 330 mg in the morning of the fourth day with a seven-day wash-out period in-between. On the fourth day, FMD of the brachial artery and VO2 on-kinetics were determined. Results: RV improved FMD in patients who had undergone coronary artery bypass grafting (CABG; -1.4 vs. 5.0%; p = .004), but not in those who had undergone percutaneous coronary intervention (PCI; 4.2 vs. -0.2%; NS). Conclusion: Acute high dose supplementation with RV improved FMD in patients after CABG surgery but impaired FMD in patients who underwent PCI. The revascularization method-related differential effects of RV may be due to its direct effects on endothelial-dependent dilator responses. Our findings have important implications for personalized treatment and stratification of older CAD patients.

Abstract
The main number of genome editing events in plant objects obtained during the last decade with the help of specific nucleases zinc finger (ZFN), transcription activator-like effector nucleases (TALEN), and clustered regularly interspaced short palindromic repeats (CRISPR)/Cas are the microindels causing frameshift and subsequent gene knock-out. The knock-ins of genes or their parts, i.e., the insertion of them into a target genome region, are between one and two orders of magnitude less frequent. First and foremost, this is associated with the specific features of the repair systems of higher eukaryotes and the availability of the donor template in accessible proximity during double-strand break (DSB) repair. This review briefs the main repair pathways in plants according to the aspect of their involvement in genome editing. The main methods for increasing the frequency of knock-ins are summarized both along the homologous recombination pathway and non-homologous end joining, which can be used for plant objects.

Abstract
This study investigated the effects of resveratrol feeding and exercise training on the skeletal muscle function and transcriptome of aged rats. Male SD rats (25 months old) were divided into the control group (Old), the daily exercise training group (Trained), and the resveratrol feeding group (Resveratrol). After 6 weeks of intervention, the body mass, grip strength, and gastrocnemius muscle mass were determined, and the muscle samples were analyzed by transcriptome sequencing. The differentially expressed genes were analyzed followed by GO enrichment analysis and KEGG analysis. The Old group showed positive increases in body mass, while both the Trained and Resveratrol groups showed negative growth. No significant differences in the gastrocnemius muscle index and absolute grip strength were found among the three groups. However, the relative grip strength was higher in the Trained group than in the Old group. Only 21 differentially expressed genes were identified in the Trained group vs. the Old group, and 12 differentially expressed genes were identified in the Resveratrol group vs. the Old group. The most enriched GO terms in the Trained group vs. the Old group were mainly associated with RNA metabolic processes and transmembrane transporters, and the significantly upregulated KEGG pathways included mucin-type O-glycan biosynthesis, drug metabolism, and pyrimidine metabolism. The most enriched GO terms in the Resveratrol group vs. the Old group were primarily associated with neurotransmitter transport and synaptic vesicle, and the upregulated KEGG pathways included synaptic vesicle cycle, nicotine addiction, retinol metabolism, insulin secretion, retrograde endocannabinoid signaling, and glutamatergic synapse. Neither exercise training nor resveratrol feeding has a notable effect on skeletal muscle function and related gene expression in aged rats. However, both exercise training and resveratrol feeding have strong effects on weight loss, which is beneficial for reducing the exercise loads of the elderly.

Abstract
OBJECTIVE This study aims to evaluate the relationship between apoptosis and autophagy induced by resveratrol (Res) in SKOV3 human ovarian cancer cell lines. METHODS The experiment was divided into four groups: normal control group, Res group, Res combined with autophagy inhibitor 3-methyladenine (Res+3-MA) group, and Z-VAD-FMK group. SKOV3 cells were cultured and treated with Res and 3-MA for 24 hours. The processing concentration of Res was screened out by the Cell Counting Kit-8 (CCK8) assay. The cell survival rate was measured by the CCK8 assay. The expression of bule-associated protein light chain 3 beta 2 (LC3-II) and Beclin-1 was detected using Western blot analysis. The percentages of apoptotic and autophagic cells were analyzed using flow cytometry. RESULTS The cell survival rate significantly decreased as Res concentration increased, and the differences were statistically significant (P < 0.05). The processing concentration of Res was 25 μmol/L. After treatment with Res for 24 hours, the expression levels of autophagy-related protein LC3 and Beclin-l were significantly higher than in the other groups. Furthermore, the expression of LC3 and Beclin-l significantly declined in the Res+3-MA group compared with the Res group. However, the percentage of autophagic cells significantly decreased from 37.0% ± 4.24% to 6.1% ± 0.28%, and the percentage of apoptotic cells significantly increased from 24% ± 4.55% to 67.0% ± 4.3%; and the differences were statistically significant ( P < 0.05). CONCLUSION Res can induce autophagy to inhibit apoptosis in tumor SKOV3 cells, and inhibition of Res+3-MA could not only enhance the effects of chemotherapy but also prevent normal cells from tumorigenesis.

Abstract
Resveratrol is a polyphenol known for its antioxidant and anti-inflammatory properties, which support its use as a treatment for variety of diseases. There are already known connections of resveratrol to chemoprevention of cancer because of its ability to prevent tumor initiation and inhibit tumor promotion and progression. Resveratrol is also believed to be important in cardiovascular diseases and neurological disorders, such as Alzheimer's disease. Using an inverse molecular docking approach, we sought to find new potential targets of resveratrol. Docking of resveratrol into each ProBiS predicted binding site of >38 000 protein structures from the Protein Data Bank was examined, and a number of novel potential targets into which resveratrol was docked successfully were found. These explain known actions or predict new effects of resveratrol. The results included three human proteins that are already known to bind resveratrol. A majority of proteins discovered however have no already described connections with resveratrol. We report new potential target human proteins and proteins connected with different organisms into which resveratrol can dock. Our results reveal previously unknown potential target human proteins, whose connection with cardiovascular and neurological disorders could lead to new potential treatments for variety of diseases. We believe that our research could help in future experimental studies on revestratol bioactivity in humans.

Abstract
Resveratrol, the phenolic substance isolated initially from Veratrum grandiflorum and richly present in grapes, wine, peanuts, soy, and berries, has been attracting attention of scientists and medical doctors for many decades. Herein, we review its effects on the vascular system. Studies utilizing cell cultures and pre-clinical models showed that resveratrol alleviates oxidative stress and inflammation. Furthermore, resveratrol suppresses vascular smooth muscle cell proliferation, promotes autophagy, and has been investigated in the context of vascular senescence. Pre-clinical models unambiguously demonstrated numerous vasculoprotective effects of resveratrol. In clinical trials, resveratrol moderately diminished systolic blood pressure in hypertensive patients, as well as blood glucose in patients with diabetes mellitus. Yet, open questions remain, as exemplified by a recent report which states that the intake of resveratrol might blunt certain positive effects of exercise in older persons, and further research addressing the framework for long-term use of resveratrol as a food supplement, will stay in demand.

Abstract
Despite all the development of modern medicine, around 100 compounds derived from natural products were undergoing clinical trials only at the end of 2013. Among these natural substances in clinical trials, we found the resveratrol (RES), a pharmacological multi-target drug. RES analgesic properties have been demonstrated, although the bases of these mechanisms have not been fully elucidated. The aim of this study was to evaluate the involvement of opioid and cannabinoid systems in RES-induced peripheral antinociception. Paw withdrawal method was used and hyperalgesia was induced by carrageenan (200 μg/paw). All drugs were given by intraplantar injection in male Swiss mice (n = 5). RES (100 μg/paw) administered in the right hind paw induced local antinociception that was antagonized by naloxone, non-selective opioid receptor antagonist, and clocinnamox, μOR selective antagonist. Naltrindole and nor-binaltorfimine, selective antagonists for δOR and kOR, respectively, did not reverse RES-induced peripheral antinociception. CB1R antagonist AM251, but not CB2R antagonist AM630, antagonized RES-induced peripheral antinociception. Peripheral antinociception of RES intermediate-dose (50 μg/paw) was increased by: (i) bestatin, inhibitor of endogenous opioid degradation involved-enzymes; (ii) MAFP, inhibitor of anandamide amidase; (iii) JZL184, inhibitor of 2-arachidonoylglycerol degradation involved-enzyme; (iv) VDM11, endocannabinoid reuptake inhibitor. Acute and peripheral administration of RES failed to affect the amount of μOR, CB1R and CB2R. Experimental data suggest that RES induces peripheral antinociception through μOR and CB1R activation by endogenous opioid and endocannabinoid releasing.

Abstract
Stress-induced premature senescence program is known to be activated in cells by various genotoxic stressors, and oxidative stress is considered to be the main of those. To this end, many studies discover antioxidants as protective anti-aging agents. In the current study, we examined the effects of different antioxidants (Tempol, resveratrol, NAC, DPI) on the mesenchymal stem cells maintained in normal physiological conditions. We used high, but non-cytotoxic antioxidant doses which are widely used in laboratory practice to protect cells from oxidative damage. We show that these substances induce reversible block of cell proliferation and do not cause any genotoxic effects when applied to the quiescent cells. However, the same doses of the same substances, when applied to the proliferating cells, can induce irreversible cell cycle arrest, DNA strand breaks accumulation and DNA damage response activation. As a consequence, antioxidant-induced DNA damage results in the stress-induced premature senescence program activation. We conclude that high doses of antioxidants, when applied to the proliferating cells that maintain physiological levels of reactive oxygen species, can cause DNA damage and induce premature senescence which suggests to re-estimate believed unconditional anti-aging antioxidant properties.

Abstract
BACKGROUND Cocoa exhibits high content of phenolic compounds, among which trans-resveratrol stands out, associated with several bioactive activities such as antioxidant properties. Chocolate contains reduced amounts of these bioactive compounds due to losses during the production process. Therefore, this study aimed to assess changes in total phenolic content, and specifically trans-resveratrol, as well as changes in the antioxidant activity of cocoa and its products during industrial production of chocolate. RESULTS A total of ten different cocoa products were analyzed. The processes of fermentation and roasting caused significant loss of total phenolic compounds and antioxidant activity. The high temperature of roasting had a major influence on this loss (71% for total phenolic compounds and 53-77% for antioxidant activity), except for trans-resveratrol. The trans-resveratrol content formed after fermentation (9.8 μg kg-1 ) showed little variation during the processes, and it was detected in higher concentrations both in natural (11.4 μg kg-1 ) and in alkalized cocoa powder (13.5 μg kg-1 ). Alkalization of cocoa products led to loss of capacity of deactivating superoxide radical. CONCLUSION These findings contribute to the optimization of the production process of chocolate and other food products containing cocoa and its derivatives, aiming to better preserve their bioactive compounds. © 2018 Society of Chemical Industry.

Abstract
Resveratrol was first isolated in 1939 by Takaoka from Veratrum grandiflorum O. Loes. Following this discovery, sporadic descriptive reports appeared in the literature. However, spurred by our seminal paper published nearly 60 years later, resveratrol became a household word and the subject of extensive investigation. Now, in addition to appearing in over 20,000 research papers, resveratrol has inspired monographs, conferences, symposia, patents, chemical derivatives, etc. In addition, dietary supplements are marketed under various tradenames. Once resveratrol was brought to the limelight, early research tended to focus on pharmacological activities related to the cardiovascular system, inflammation, and cancer but, over the years, the horizon greatly expanded. Around 130 human clinical trials have been (or are being) conducted with varying results. This may be due to factors such as disparate doses (ca. 5 to 5,000 mg/day) and variable experimental settings. Further, molecular targets are numerous and a dominant mechanism is elusive or nonexistent. In this context, the compound is overtly promiscuous. Nonetheless, since the safety profile is pristine, and use as a dietary supplement is prevalent, these features are not viewed as detrimental. Given the ongoing history of resveratrol, it is reasonable to advocate for additional development and further clinical investigation. Topical preparations seem especially promising, as do conditions that can respond to anti-inflammatory action and/or direct exposure, such as colon cancer prevention. Although the ultimate fate of resveratrol remains an open question, thus far, the compound has inspired innovative scientific concepts and enhanced public awareness of preventative health care.

The effects of trans-resveratrol on insulin resistance, inflammation, and microbiota in men with the metabolic syndrome: A pilot randomized, placebo-controlled clinical trial. J Clin Transl Res 2018; 4:122-135. [PMID: 30873501 PMCID: PMC6412609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2018] [Revised: 10/18/2018] [Accepted: 12/04/2018] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND AND AIM The metabolic syndrome (MetS) is a pathological condition comprised of abdominal obesity, insulin resistance, hypertension, and hyperlipidemia. It has become a major threat globally, resulting in rapidly increasing rates of diabetes, coronary heart disease, and stroke. The polyphenol resveratrol (RES) is believed to improve glucose homeostasis and insulin resistance by activating sirtuin, which acetylates and coactivates downstream targets and affects glucose and lipid homeostasis in the liver, insulin secretion in the pancreas, and glucose uptake in skeletal muscle. We studied the effects of RES on insulin resistance, glucose homeostasis, and concomitant effects on adipose tissue metabolism and fecal microbiota in insulin-resistant subjects with the MetS. METHODS A total of 28 obese men with the MetS were studied during a 35-day stay in the Rockefeller University Hospital metabolic unit. Subjects were randomized to receive RES 1 g orally twice daily or placebo while kept weight stable and consuming a western-style diet. At baseline, and after 30 days of RES or placebo administration, subjects underwent testing that included a euglycemic, hyperinsulinemic clamp, 2-h oral glucose tolerance test (GTT), resting energy expenditure, daily blood pressure monitoring, abdominal adipose tissue biopsy, and fecal and blood collections. RESULTS RES induced no changes in insulin resistance but reduced the 120-min time point and the area under the curve for glucose concentration in the 2-h GTT. In post-hoc analysis, Caucasian subjects showed a significant improvement in insulin sensitivity and glucose homeostasis after GTT, whereas non-Caucasians showed no similar effects. Levels of fasting plasma RES and its primary metabolite dihydroresveratrol were variable and did not explain the racial differences in glucose homeostasis. RES administration to Caucasian subjects leads to an increase in several taxa including Akkermansia muciniphila. CONCLUSIONS RES 2 g administered orally to obese men with MetS and insulin resistance marginally altered glucose homeostasis. However, in a small group of Caucasians, insulin resistance and glucose homeostasis improved. No concomitant changes in adipose tissue metabolism occurred, but fecal microbiota showed RES-induced changes. RELEVANCE FOR PATIENTS The MetS increases the risk of diabetes, heart disease, and stroke. A major component of the syndrome is insulin resistance, resulting in systemic inflammation and hyperinsulinemia. The primary treatment consists of lifestyle changes, improved diet, and increased physical activity. This is often unsuccessful. In this study, RES was well tolerated. In Caucasian men, it significantly improved insulin sensitivity and glucose homeostasis. Similar results were found in studies that consisted exclusively of Caucasian men. However, RES presents a novel addition to the current treatment of the MetS and its sequelae.

Abstract
Over the years, scientific researches have validated the healing benefits of many psychopharmacotherapeutic plant-based drugs to ameliorate psychiatric disorders. In contrast, the use of chemical procedures to isolate and purify specific compounds from plants that have been used to treat autism spectrum disorders (ASDs) and its clinical features may contribute to improve the quality of life of many patients. Also, herbal pharmacological treatments could improve the core symptoms of autism with fewer side effects. This review will focus on the uses and actions of phytopharmaceuticals in the behavioral conditions of ASDs. A large number of natural compound-based plant drugs have been tested in murine models of autism and in clinical trials with remarkable success in reversing the core and associated behaviors with autism such as flavonoids, cannabinoids, curcuminoids, piperine, resveratrol, and bacosides. This plant-based drug alternative is safer given that many psychiatric disorders and neurodegenerative pathologies do not often respond well to currently prescribed medications or have significant side effects. However, it is noteworthy to consider the need for large clinical trials to determine safety and efficacy. Many results are based on case reports or small size samples, and often the studies are open label. Standardization of procedures (i.e., purity and concentrations) and quality controls are strictly required to ensure the absence of side effects.

Abstract
OBJECTIVES Resveratrol is a naturally occurring antioxidant with therapeutic potential in prevention and treatment of neoplastic disease and other human disorders. However, net clearance of resveratrol in humans is very high, mainly due to glucuronide conjugation. This leads to extensive presystemic extraction and low plasma concentrations after oral dosage. The present study evaluated the effect of probenecid, an inhibitor of glucuronide conjugation, on resveratrol metabolism in vitro. METHODS Biotransformation of resveratrol to its 3-O-glucuronide and 4'-O-glucuronide conjugates was studied in vitro using human liver microsomal preparations. The mechanism and inhibitory potency of probenecid were evaluated based on a mixed competitive-noncompetitive inhibition model. KEY FINDINGS Probenecid inhibition of resveratrol 3-O-glucuronidation was predominantly noncompetitive, with an inhibition constant (Ki ) averaging 3.1 mm. CONCLUSIONS The ratio of in vivo maximum concentration of probenecid [I] during usual clinical use to the in vitro Ki value ([I]/Ki ) exceeds the boundary value of 0.1, used by regulatory agencies to identify the possibility of clinical drug interactions. This finding, together with the known property of probenecid as an inhibitor of glucuronide conjugation in humans, suggests that probenecid could serve as a pharmacokinetic boosting agent to enhance systemic exposure to resveratrol in humans.

Abstract
BACKGROUND The outcome of ischemic stroke depends on multiple factors and their function of each other. Studies have shown that Sirtuin1 (SIRT1) plays a chief role in the key procedure during ischemia/hypoxia by protecting against cellular stress and controlling the metabolic pathways. AIMS To explore the alterations in serum SIRT1 concentrations in acute ischemic stroke (AIS) patients and the relationship between SIRT1 and poststroke dementia, anxiety, and depression. METHODS One hundred and twenty four consecutive patients with clinically diagnosed AIS were recruited to participate in the study. Serum SIRT1 levels were measured using a commercially available ELISA equipment for SIRT1 (Cusabio, Wuhan, China). In 1 year after admission, the severity of stroke was assessed with the National Institutes of Health Stroke Scale score, and the functional outcome was measured by a modified Rankin scale, the Hamilton Anxiety Scale scores were evaluated to define patients with or without anxiety, and the Hamilton Depression Scale scores for depression. RESULTS We found the levels of serum SIRT1 was significantly higher (P = .036) in AIS patients (.62 ± .77 ng/mL) compared with healthy control subjects (.45 ± .69 ng/mL), but not significantly higher SIRT1 concentration (.58 ± .69 versus .64 ± .81 ng/mL, P = .298) than patients in the unfavorable functional outcome group. CONCLUSIONS There is no potential diagnostic and prognostic role of SIRT1 in AIS-related dementia, anxiety, and depression. The role of SIRT1 in AIS among human race needs to be further investigated.

Abstract
The aim of this study was to evaluate the cytotoxicity of a series of seven 4'-methylthio-trans-stilbene derivatives against cancer cells: MCF7 and A431 in comparison with non-tumorigenic MCF12A and HaCaT cells. The mechanism of anti-proliferative activity of the most cytotoxic trans-resveratrol analogs: 3,4,5-trimethoxy-4'-methylthio-trans-stilbene (3,4,5-MTS) and 2,4,5-trimethoxy-4'-methylthio-trans-stilbene (2,4,5-MTS) was analyzed and compared with the effect of trans-resveratrol. All the compounds that were studied exerted a stronger cytotoxic effect than trans-resveratrol did. MCF7 cells were the most sensitive to the cytotoxic effect of trans-resveratrol analogs with IC50 in the range of 2.1-6.0 µM. Comparing the cytotoxicity of 3,4,5-MTS and 2,4,5-MTS, a significantly higher cytotoxic activity of these compounds against MCF7 versus MCF12A was observed, whereas no significant difference was observed in cytotoxicity against A431 and HaCaT. In the series of 4'-methylthio-trans-stilbenes, 3,4,5-MTS and 2,4,5-MTS were the most promising compounds for further mechanistic studies. The proapoptotic activity of 3,4,5-MTS and 2,4,5-MTS, estimated with the use of annexin-V/propidium iodide assay, was comparable to that of trans-resveratrol. An analysis of cell cycle distribution showed a significant increase in the percentage of apoptotic cells and G2/M phase arrest in MCF7 and A431 as a result of treatment with 3,4,5-MTS, whereas trans-resveratrol tended to increase the percentage of cells in S phase, particularly in epithelial breast cells MCF12A and MCF7. Both trans-stilbene derivatives enhanced potently tubulin polymerization in a dose-dependent manner with sulfur atom participating in the interactions with critical residues of the paclitaxel binding site of β-tubulin.

Abstract
Pre-clinical data and human trials indicate that resveratrol supplementation may help to counteract diabetes. Several mechanisms of action have been proposed to explain its metabolic benefits, including activation of sirtuins and estrogen receptors (ER) to promote glucose transporter type-4 (GLUT4) translocation and increase glucose uptake. Resveratrol can also enhance vasodilator function, yet the possibility that this action might help to alleviate insulin resistance in type-2 diabetes mellitus has received little attention. In this brief review we propose that, by restoring impaired endothelium-dependent vasodilatation in insulin resistant individuals resveratrol increases blood perfusion of skeletal muscle, thereby facilitating glucose delivery and utilization with resultant improvement of insulin sensitivity. Thus, circulatory improvements by vasoactive nutrients such as resveratrol may play a role in preventing or alleviating insulin resistance.

Abstract
Recently, resveratrol showed induction of γ-globin mRNA synthesis in human erythroid precursors and reducing oxidative stress in red cells of thalassemia patients in many in vitro studies. We aimed to investigate the efficacy and safety of resveratrol, for the first time, in non-transfusion-dependent beta-thalassemia intermedia (B-TI) in Southern Iran. In this double-blind randomized clinical trial, 54 patients with B-TI were investigated during 6 months between October 2016 and March 2017. Patients were randomly allocated into three groups by simple randomization method. Group 1 (hydroxyurea (HU) and placebo, 18 patients), group 2 (resveratrol/piperine and placebo, 16 patients), and group 3(HU and resveratrol/piperine, 20 patients). Primary end point was considered as change in hemoglobin (Hb) levels and need for blood transfusion. Drug safety was considered as a secondary end point. Mean age of the patients was 28.2 ± 5.6 (18-42) years. Response rate was not significantly different among the three groups (P > 0.05). Higher percentages of adverse events were detected in groups 2 (31.3%) and 3 (25%) compared to group 1 (5.6%). However, the difference was not statistically significant (P > 0.05). All reported adverse events were gastrointestinal symptoms. Resveratrol showed a similar efficacy with HU in the small population of non-transfusion B-TI patients during a 6-month follow-up. Complications, mostly gastrointestinal, were observed more frequently in resveratrol groups compared to the HU group. Although it was not statistically significant, more attention should be given to safety and efficacy of resveratrol as an oral HbF-augmenting agent.

Abstract
The stilbene derivative resveratrol (3,5,4'-trihydroxy-stilbene; RESV) has become the subject of interest of many researchers and the pharmaceutical industries due to its well-acclaimed beneficial biological activities. Although earlier research tended to focus on the effects of RESV on cardiovascular disorders, many other studies have described the beneficial effects of RESV in the areas of cancer chemoprevention and inflammation and interest of researchers on this compound is still increasing. It is now well accepted that the effect of RESV is not just due to its so called "antioxidant" activity but mainly (if not only) because of the ability of this compound to trigger cell signaling pathways and gene expression involved in cellular defense systems. Many "in vitro" studies on RESV did not take into account that although its oral absorption is about 75% it undergoes rapid metabolism and the concentration in the blood stream is almost undetectable. For this reason interest in the topical usage of RESV by cosmeceutical skin care brands has exponentially increased in the last decade reporting in general very promising results on its beneficial effect in protecting the skin from outdoor insults, but there is still some controversy on its topical usage mainly surrounding the concentration used. Therefore, more basic research on the topical application of RESV should be performed to better understand the way it prevents cutaneous damage and whether it could be recommended as a preventive skin aging agent for all skin insults.

Resveratrol and Related Stilbenoids, Nutraceutical/Dietary Complements with Health-Promoting Actions: Industrial Production, Safety, and the Search for Mode of Action. Compr Rev Food Sci Food Saf 2018; 17:808-826.

Abstract
This paper reviews the potential of stilbenoids as nutraceuticals. Stilbenoid compounds in wine are considered key factors in health-promoting benefits. Resveratrol and resveratrol-related compounds are found in a large diversity of vegetal products. The stilbene composition varies from wine to wine and from one season to another. Therefore, the article also reviews how food science and technology and wine industry may help in providing wines and/or food supplements with efficacious concentrations of stilbenes. The review also presents results from clinical trials and those derived from genomic/transcriptomic studies. The most studied stilbenoid, resveratrol, is a very safe compound. On the other hand, the potential benefits of stilbene intake are multiple and are apparently due to downregulation more than upregulation of gene expression. The field may take advantage from identifying the mechanism of action(s) and from providing useful data to show evidence for specific health benefits in a given tissue or for combating a given disease.

Abstract
Resveratrol is a stilbenoid phytoalexin with promising myriad health benefits predominantly contributed by the trans ( E) diastereomeric form. A recent study has implicated the cis ( Z) diastereomer in human health. This stereoisomer binds with high affinity to human tyrosyl-tRNA synthetase, initiating a downstream cascade that promotes the expression of genes associated with the cellular stress response. We discovered that the nonplanar structure of the cis-resveratrol conformer possesses certain chiral signals in its simulated vibrational circular dichroism (VCD) and Raman optical activity (ROA) spectra. These features may be used for the optical detection of the binding event and in understanding the more diversified biological roles of trans-resveratrol over cis-resveratrol. We use a density functional theory model, which is validated against the known results for the E diastereomer. The Z diastereomer is significantly nonplanar and can exist in two helical atropisomeric forms. These forms exchange rapidly in solution, but only one is observed to bind with the synthetase. This suggests that the binding may generate an enantiomeric excess, leading to detectable changes in the vibrational optical activity spectra. We identify candidate features at 998, 1649, and 1677 cm-1 in the ROA and at 1642 and 3834 cm-1 in the VCD spectra of Z-resveratrol that may be useful for this purpose.
