Eom SY, Kim MM. The effect of IGFBP3 gene knockout by the CRISPR/Cas9 system on the IGF-1 pathway in murine cells. Arch Gerontol Geriatr 2024; 125:105484. [PMID: 38838451 DOI: 10.1016/j.archger.2024.105484] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/23/2024] [Accepted: 05/06/2024] [Indexed: 06/07/2024]
Abstract
BACKGROUND The IGF-1 signaling pathway has been deeply involved in the aging mechanism. The insulin-like growth factor binding protein 3 (IGFBP-3) is a protein that binds to IGF-1 that regulates growth, survival, and aging. OBJECTIVE The purpose of this study was to investigate the impact of the IGFBP3 gene knockout (KO) on the expressions of aging-related proteins and genes using the CRISPR/Cas9 system. METHODS The IGFBP3 gene knockout (KO) was performed by the CRISPR/Cas9 system. Sanger DNA sequencing and Indel analyses were used to verify the induction of mutation. RESULTS First, Sanger DNA sequencing was used to analyze the IGFBP3 gene knockout in murine cells (B16F1). The isolation of three colonies with the mutated DNA sequences in the IGFBP3 gene was validated. In addition, the expression levels of the IGFBP3 gene and protein in the edited B16F1 cells were lower than in those of normal B16F1 cells in western blot analysis as well as RT-PCR and qPCR. Moreover, IGFBP3 gene KO cells enhanced the level of SA-ß-gal staining and short telomere length compared to normal B16F1 cells. In particular, it was found that the expression levels of senescence-related proteins such as PI3K, AKT1, PDK1, and p53 were higher in IGFBP3 gene KO cells than in normal cells in both the absence and presence of IGF-1. CONCLUSIONS Therefore, the above findings could provide a clue that IGFBP3 could play a key role in the aging mechanism.

Abstract
Polyphenols, the main antioxidants of diet, have shown anti-inflammatory, antioxidant and anticarcinogenic activities. Here, we compared the effects of four polyphenolic compounds on ROS production and on the levels of matrix metalloproteinase (MMP)-2 and -9, which represent important pathogenetic factors of breast cancer. THP-1 differentiated macrophages were activated by LPS and simultaneously treated with different doses of a green tea extract (GTE), resveratrol (RSV), curcumin (CRC) and an olive fruit extract (oliplus). By using the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, we found that all of the tested compounds showed antioxidant activity in vitro. In addition, GTE, RSV and CRC were able to counteract ROS production induced by H2O2 in THP-1 cells. As assessed by a zymographic analysis of THP-1 supernatants and by an "in-gel zymography" of a pool of sera from patients with breast cancer, the antioxidant compounds used in this study inhibited both the activity and expression of MMP-2 and MMP-9 through different mechanisms related to their structures and to their ability to scavenge ROS. The results of this study suggest that the used antioxidants could be promising agents for the prevention and complementary treatment of breast cancer and other diseases in which MMPs play a pivotal role.

Abstract
The objective of this study was to investigate the protective effects and the underlying mechanisms of resveratrol (RES) against hydrogen peroxide (H2O2)-induced oxidative stress in bovine skeletal muscle cells (BMCs). Pretreatment of BMCs with RES prior to H2O2 exposure increased cell viability, attenuated reactive oxygen species, and stabilized the redox state. H2O2 exposure activated sirtuin type 1 (SIRT1) and nuclear factor E2-related factor 2 (NRF2)-mediated signaling pathways. Pretreatment with RES did not alter SIRT1-regulated genes but inhibited the upregulation of NRF2, whereas enhanced heme oxygenase 1 (HO-1) expression. Pretreatment with RES prior to H2O2 exposure failed to suppress NRF2 expression when NRF2 was knocked down by RNA interference. However, HO-1 expression still could be induced by RES. These results suggest that RES has benifical effects against oxidative stress. NRF2-mediated pathway play an important role, and HO-1 upregulation is the key process in RES regulation. RES may be used as a therapeutic agent for meat quality improvement in beef cattle.

Abstract
Endometriosis, characterized by macroscopic lesions in the ovaries, is a serious problem for women who desire conception. Damage to the ovarian cortex is inevitable when lesions are removed via surgery, which finally decreases the ovarian reserve, thereby accelerating the transition to the menopausal state. Soon after cessation of ovarian function, in addition to climacteric symptoms, dyslipidemia and osteopenia are known to occur in women aged >50 years. Epidemiologically, there are sex-related differences in the frequencies of dyslipidemia, hypertension, and osteoporosis. Females are more susceptible to these diseases, prevention of which is important for healthy life expectancy. Dyslipidemia and hypertension are associated with the progression of arteriosclerosis, and arteriosclerotic changes in the large and middle blood vessels are one of the main causes of myocardial and cerebral infarctions. Osteoporosis is associated with aberrant fractures in the spine and hip, which may confine the patients to the bed for long durations. Bone resorption is accelerated by activated osteoclasts, and rapid bone remodeling reduces bone mineral density. Resveratrol, a plant-derived molecule that promotes the function and expression of the sirtuin, SIRT1, has been attracting attention, and many reports have shown that resveratrol might exert cardiovascular protective effects. Preclinical reports also indicate that it can prevent bone loss and endometriosis. In this review, I have described the possible protective effects of resveratrol against arteriosclerosis, osteoporosis, and endometriosis because of its wide-ranging functions, including anti-inflammatory and antioxidative stress functions. As ovarian function inevitably declines after 40 years, intake of resveratrol can be beneficial for women with endometriosis aged <40 years.

Abstract
The aim of the study was to compare the effects of three natural bioactive compounds (and their combinations) on normal vs. tumour-transformed mouse cells. The cytotoxic effect of Aeruginosin-865 (Aer), capsaicin (Cap), resveratrol (Res) and their combinations was evaluated on normal hepatocytes (AML) and tumour cells derived from livers (Hepa) and kidneys (Renca). Various concentrations from 25 to 200 μM of tested substances were used. Only the Aer + Res combination and a low concentration of Res had a significant cytotoxic effect on Hepa and Renca and no significant cytotoxic effect on AML. Cap had a significant cytotoxic effect on all tested cell lines, but tumour-derived cells showed higher resistance than AML. A significantly increased cytotoxicity was found in the combination of Cap + Res compared to each substance alone. All types of cells showed similar sensitivity to the cytotoxic effect of Cap + Res. Because of a possible hepatotoxic effect, we recommend further investigations into side-effects of Cap + Res. No cytotoxic effect was described in Cap + Aer or in Aer alone. Only substances with a significant cytotoxic effect on tumour cells and no cytotoxic effect on normal cells can be potentially used in anticancer treatment. According to the results, only Res or the combination of Aer + Res can be recommended for further evaluation in the process of new anticancer drug development. The potential hepatotoxic effect of Cap + Res can significantly limit the utilisation of these substances in anticancer treatment.

Abstract
The risk of cancer increases with aging due to the accumulation of cellular deterioration that can spread to other organs through the blood and lymphatic vessels. Therefore, the inhibition of metastasis is a major concern for the treatment of cancer. Several synthetic drugs have been developed for the treatment of various cancers. However, these drugs are effective; nonspecific action and side effects on the normal human cells limit their wide acceptance, thus demanding some potential alternative. Hence, the present study emphasizes investigating the effect of a methanolic extract of Agrimonia Pilosa (APLME) on matrix metalloproteinases (MMPs) in human fibroblast sarcoma cells. The action of APLME on MMP-2 and MMP-9 was investigated using gelatin zymography. APLME suppressed the activities of MMP-2 and MMP-9 in PMA (phorbol myristate acetate)-treated HT1080 cells. In addition, western blot analysis and immunofluorescence were performed to investigate the effect of APLME on the expression of the proteins that are the major proteins involved in cell invasion and metastasis. APLME treatment inhibited the expression of MMP-2 and MMP-9 in addition to the activations of JNK, ERK, and AKT-1. Furthermore, APLME was observed to suppress cell invasion related to metastasis using cell invasion assay. Therefore, the above findings indicate that APLME inhibits the expression activity of MMP-2 and MMP-9 via inactivation of ERK and JNK in addition to AKT-1, leading to inhibiting cell invasion. Therefore, these results indicate that APLME may be used as a candidate substance for inhibiting cell invasion. PRACTICAL APPLICATIONS: Cancer increases the cell invasion to other organs through the blood and lymphatic vessels. Cancer cells deplete the nutrients and create new blood vessels that infiltrate and metastasize to other tissues. Therefore, this present study examined the effect of Agrimonia Pilosa on cell invasion. It was found that Agrimonia Pilosa methanolic extract inhibited the invasion of cancer cells through the inactivation of ERK and JNK. In addition, APLME reduced the activation and protein expression of MMP-2 and MMP-9 in addition to AKT-1. Thus, APLME can be utilized as a potential alternative therapeutic agent for inhibiting metastasis.

Abstract
INTRODUCTION Osteosarcoma is the most common primary malignancy of the bone. The existing adjuvant chemotherapy regimens, while improving the overall survival, have been limited by the significant systemic toxicity. Substantial clinical and research efforts are being invested to develop novel pharmaceutical agents. Resveratrol (Res) has been suggested to have a chemopreventive effect. However, the mechanism of Res in osteosarcoma remains to be elucidated. MATERIAL AND METHODS The MG-63 osteosarcoma cell culture model was used to investigate the chemotherapeutic effect of Res. MTT assay, wound healing assay, and Transwell migration assay were used to document the effect of Res on cell proliferation, migration, and invasion, respectively. Apoptosis in MG-63 cells was quantified with the TUNEL assay. Western blotting analysis was used to examine the molecular changes following Res treatment. Data processing and analysis were conducted using GraphPad Prism 5.0. P < 0.05 was considered statistically significant. RESULTS Our data suggested that Res blocks cell proliferation, migration, and invasion, and activates apoptotic cell death in osteosarcoma MG-63 cells. We found that Res potentially down-regulates nuclear factor κB (NF-κB) and Akt intracellular signaling transduction. Moreover, the combination of Res and pyrrolidine dithiocarbamate (PDTC), an NF-κB inhibitor, resulted in synergistic growth inhibition of osteosarcoma. CONCLUSIONS Our in vitro preclinical study in the MG-63 cell line model supports the translation of Res to the clinical management of patients with osteosarcoma.

Abstract
Growing evidence suggests that telomeres, telomerase, matrix metalloproteinase-9 (MMP-9), and SIRT1 (sirtuin1) are involved in the pathophysiology of neuropsychiatric and neurodevelopmental disorders. However, whether these molecules are contributors to attention-deficit/hyperactivity disorder (ADHD) has been little explored and poorly understood. This study aimed to determine the potential role of telomerase, MMP-9, and SIRT1 in children with ADHD. The study was performed on 46 children with ADHD aged between 8 and 14 and 43 healthy children matching in age and gender. Children were evaluated by Kiddie-Sads-Present and Lifetime Version, Conners' Parent Rating Scale-Revised Short Form (CPRS-RS) and Stroop test. Serum telomerase, MMP-9, and SIRT1 levels were measured by a quantitative sandwich enzyme-linked immunosorbent assay. MMP-9 and telomerase levels were significantly higher and SIRT1 levels were significantly lower in patients with ADHD than those of controls. All three molecules were significantly associated with both the severity of ADHD symptoms and cognitive functions. This is the first attempt to indicate that the important role of telomerase, MMP-9, and SIRT1 in ADHD, and the association of all these molecules with the severity of ADHD and cognitive functions, but future studies are required to verify these results.

Abstract
Natural substances offer interesting bioactivity patterns including antiproliferative, antioxidant or cytotoxic effects. However, the safety profile of many of them has not been extensively determined. In this study, the cytotoxic effect of Aeruginosin-865, resveratrol and capsaicin at different concentrations was tested on normal mouse cells (NIH/3T3) and tumour fibroblasts (WEHI-13VAR) as well as on liver- and kidney-derived cells from fallow deer. A lactate dehydrogenase cytotoxicity assay kit was used to measure cell death in response to treatment with the test substances. It was found that NIH/3T3 cells tolerated Aeruginosin-865 (10-200 μM) and resveratrol (5-100 μM) treatment without any cytotoxic effect, while capsaicin exerted a cytotoxic effect only at the highest tested concentration (200 μ M). Mouse fibrosarcoma cells were more sensitive to the cytotoxic effect of all three compounds where Aeruginosin-865 (100-200 μM) and resveratrol (50–100 μM) showed high-dose cytotoxicity and capsaicin showed low- and high-dose cytotoxicity (25 μM and 200 μ M). The three tested compounds at the highest concentrations were found to be cytotoxic to both liver- and kidney-derived cells from fallow deer. Overall, the results indicate that the cytotoxic effects of the three tested natural substances on cells derived from fallow deer and mouse tumour fibroblasts differ significantly from those exerted on normal fibroblasts. The results demonstrate the potential of these natural compounds as therapeutic agents and pave the way for future in vivo toxicological investigations.

Abstract
The present study aimed to investigate the effect of tanshinone II, isolated from Salvia miltiorrhiza Bunge, on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in rats. Male Sprague-Dawley rats were divided into three groups: Control, LPS and tanshinone II. Animals in the tanshinone II and LPS groups were administered 10 mg/kg LPS, whereas those in the control group received an equal volume of normal saline. Tanshinone II treatment group were injected with 30 nm/kg tanshinone II at 1 h after LPS administration. The results revealed that LPS administration increased the bronchoalveolar lavage fluid protein concentration significantly compared with the control group. However, tanshinone II treatment significantly inhibited the LPS-induced increase in protein level. Treatment of the LPS-administered rats with tanshinone II prevented the formation of pulmonary edema, which was evidenced by low values for wet to dry lung weight ratio. The activity of myeloperoxidase and expression of malondialdehyde were significantly lower in lung homogenates from the tanshinone II group compared with the LPS group. Furthermore, tanshinone II treatment inhibited the expression of tumor necrosis factor-α and interleukin-6 in the blood plasma. Tissue sections of the tanshinone II group exhibited normal morphology and absence of neutrophil accumulation. However, in the LPS group, neutrophils accumulated and penetrated into the pulmonary tissues. These results suggested that tanshinone II protects the rats from LPS-induced ALI. Therefore tanshinone II may have clinical applications in the treatment of ALI.

Resveratrol and pinostilbene confer neuroprotection against aging-related deficits through an ERK1/2-dependent mechanism. J Nutr Biochem 2017; 54:77-86.

Abstract
Age-related declines in motor function may be due, in part, to an increase in oxidative stress in the aging brain leading to dopamine (DA) neuronal cell death. In this study, we examined the neuroprotective effects of natural antioxidants resveratrol and pinostilbene against age-related DAergic cell death and motor dysfunction using SH-SY5Y neuroblastoma cells and young, middle-aged, and old male C57BL/6 mice. Resveratrol and pinostilbene protected SH-SY5Y cells from a DA-induced decrease in cell viability. Dietary supplementation with resveratrol and pinostilbene inhibited the decline of motor function observed with age. While DA and its metabolites (DOPAC and HVA), dopamine transporter, and tyrosine hydroxylase levels remain unchanged during aging or treatment, resveratrol and pinostilbene increased ERK1/2 activation in vitro and in vivo in an age-dependent manner. Inhibition of ERK1/2 in SH-SY5Y cells decreased the protective effects of both compounds. These data suggest that resveratrol and pinostilbene alleviate age-related motor decline via the promotion of DA neuronal survival and activation of the ERK1/2 pathways.

Abstract
Bone cancer is a malignant primary tumour of the bone with different typing, such as, osteosarcoma, chondrosarcoma, Ewing's sarcoma and fibrosarcoma. Despite the clinical efficacy of conventional therapies of bone cancer, most patients eventually relapse and the disease remains incurable. Therefore, new therapeutic strategies are needed to improve patient outcome. In this review article, we have discussed the role of resveratrol in preventing bone and spinal cancers and therapeutics. Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a natural polyphenol, which has been widely reported as an anticancer molecule. Resveratrol exhibits multiple tumour-suppressing activities in bone cancer by affecting a series of critical events. It has the protective effects against oxidative injury, possesses antiproliferative activity and induces apoptosis in cancer cells. Resveratrol might be a good option for the treatment of different types of bone and spinal cancers.

Abstract
Endometriosis is characterized by the existence of endometrial tissue and stroma exterior to the uterus. Despite the high prevalence, the etiology of endometriosis remains elusive. The search for the most promising compounds for treatment of endometriosis has led to the identification of resveratrol. Resveratrol, a plant-derived polyphenolic phytoalexin, demonstrates broad-spectrum health beneficial effects, including anti-proliferative, anti-inflammatory, antineoplastic and antioxidant. Because of these properties and its wide distribution in plants, resveratrol is proposed as a great potential to treat endometriosis. In animal models of endometriosis, resveratrol supplementation has displayed beneficial results as it decreased the number and volume of endometrial implants, suppressed proliferation, vascularization, inflammation, cell survival and increased apoptosis. On the other hand, resveratrol treatment in-vitro studies, reduced invasiveness of endometriotic stromal cells (ESCs) and suppressed their inflammatory responses. In this review, we will summarize the recent studies in in-vitro and animal studies on resveratrol and endometriosis.

Abstract
Disturbances of extracellular matrix homeostasis are associated with a number of pathological conditions. The ability of extracellular matrix to provide contextual information and hence control the individual or collective cellular behavior is increasingly being recognized. Hence, newer therapeutic approaches targeting extracellular matrix remodeling are widely investigated. We reviewed the current literature showing the effects of resveratrol on various aspects of extracellular matrix remodeling. This review presents a summary of the effects of resveratrol on extracellular matrix deposition and breakdown. Mechanisms of action of resveratrol in extracellular matrix deposition involving growth factors and their signaling pathways are discussed. Involvement of phosphoinositol-3-kinase/Akt and mitogen-activated protein kinase pathways and role of transcription factors and sirtuins on the effects of resveratrol on extracellular matrix homeostasis are summarized. It is evident from the literature presented in this review that resveratrol has significant effects on both the synthesis and breakdown of extracellular matrix. The major molecular targets of the action of resveratrol are growth factors and their signaling pathways, phosphoinositol-3-kinase/Akt and mitogen-activated protein kinase pathways, transcription factors, and SIRT-1. The effects of resveratrol on extracellular matrix and the molecular targets appear to be related to experimental models, experimental environment as well as the doses.

Abstract
Deadly diseases, such as cardiovascular diseases and cancer, remain the major health problems worldwide. Research in cardiovascular diseases and genome-wide association studies were successful in indentifying the gene loci associated with these threatening diseases. Yet, a substantial number of casual factors remain unexplained. Over the last decade, a better understanding of molecular and biochemical mechanisms of cardiac diseases led to developing a rationale for combining various protective agents, such as polyphenols, to target multiple signaling pathways. The present review article summarizes recent advances of the use of polyphenols against diseases, such as cardiac diseases.

Abstract
Researchers have made considerable progress in last few decades in understanding mechanisms underlying pathogenesis of breast cancer, its phenotypes, its molecular and genetic changes, its physiology, and its prognosis. This has allowed us to identify specific targets and design appropriate chemical entities for effective treatment of most breast cancer phenotypes, resulting in increased patient survivability. Unfortunately, these strategies have been largely ineffective in the treatment of triple negative breast cancer (TNBC). Hormonal receptors lacking render the conventional breast cancer drugs redundant, forcing scientists to identify novel targets for treatment of TNBC. Two natural compounds, curcumin and resveratrol, have been widely reported to have anticancer properties. In vitro and in vivo studies show promising results, though their effectiveness in clinical settings has been less than satisfactory, owing to their feeble pharmacokinetics. Here we discuss these naturally occurring compounds, their mechanism as anticancer agents, their shortcomings in translational research, and possible methodology to improve their pharmacokinetics/pharmacodynamics with advanced drug delivery systems.

Abstract
Chronic airway inflammation and airway remodeling are the major pathophysiological characteristics of chronic obstructive pulmonary disease (COPD). Resveratrol and genistein have been previously demonstrated to have anti‑inflammatory and antioxidative properties. The present study aimed to measure the inhibitory effects of resveratrol and genistein on tumor necrosis factor (TNF)‑α and matrix metalloproteinase (MMP)‑9 concentration in patients with COPD. Lymphocytes were isolated from the blood of 34 patients with COPD and 30 healthy subjects, then randomly divided into the following four treatment groups: Control, dexamethasone (0.5 µmol/l), resveratrol (12.5 µmol/l) and genistein (25 µmol/l) groups. After 1 h of treatment, 100 µl lymphocytes were collected for nuclear factor (NF)‑κB immunocytochemical staining. After 48 h treatment, the supernatant of the lymphocytes was collected for analysis of TNF‑α and MMP‑9 concentration levels. The percentage of lymphocytes with positive nuclear NF‑κB expression was analyzed by immunocytochemical staining. The concentration levels of TNF‑α and MMP‑9 were measured using radioimmunoassay and enzyme‑linked immunosorbent assay, respectively. The present study demonstrated that the percentage of NF‑κB‑positive cells, and the levels of TNF‑α and MMP‑9 in lymphocytes from patients with COPD patients were significantly higher compared with healthy subjects. Additionally, there were positive correlations between the percentage of NF‑κB‑positive cells, and the concentration levels of TNF‑α and MMP‑9 in patients with COPD. All three factors were significantly reduced in lymphocytes treated with resveratrol and genistein, and the inhibitory effects of resveratrol on NF‑κB, TNF‑α and MMP‑9 were more potent than the effects of genistein. In conclusion, resveratrol and genistein may inhibit the NF‑κB, TNF‑α and MMP‑9‑associated pathways in patients with COPD. It is suggested that resveratrol and genistein may be potential drugs candidates for use in the treatment of COPD.

Abstract
Pulmonary arterial hypertension (PAH) is a major cause of morbidity and mortality in rheumatic diseases. Vascular remodeling due to the proliferation of pulmonary arterial smooth muscle cells (PASMCs) is central to the development of PAH. To date, it is still unclear if Silence Information Regulator 1 (SIRT1) regulates cell cycle regulators in the proliferation of PASMCs and contributes to prevention of PAH by resveratrol. In this study, we found that a significant decrease of SIRT1 expression levels in platelet-derived growth factor BB (PDGF-BB) treated human PASMCs (HPASMCs) and in monocrotaline (MCT) induced PAH rat. Overexpression of SIRT1 induced G1 phase arrest and increased p21 expression but decreased cyclin D1 expression in PDGF-BB treated HPASMCs. Moreover, resveratrol attenuated pulmonary arterial remodeling, decreased pulmonary arterial pressure, and upregulated SIRT1 and p21 expression but downregulated cyclin D1 expression in MCT induced PAH rat. Notably, knockdown of SIRT1 eliminated the regulation of resveratrol on p21 and cyclin D1 expression in PDGF-BB treated HPASMCs. These results demonstrated that SIRT1 mediated the regulation of resveratrol on the expression of cell cycle regulatory molecules. It suggests that SIRT1 exerts a protective role in PAH associated with rheumatic diseases and can be a potential treatment target.

Abstract
Resveratrol (3,5,4'-trihydroxy-trans-stilbene, RSV) is a polyphenolic compound present in a variety of plant species (including grapes) that produces a myriad of biological activities including anti-inflammatory, antioxidant and neuroprotective effects. In this study, we investigate the effects of resveratrol on the basal and glutamate-stimulated expression and activity of a tissue plasminogen activator (tPA) that plays neuromodulatory or neurotoxic roles in many different neurological situations. Under basal conditions, resveratrol decreased the tPA expression and activity without affecting the tPA mRNA level in rat primary cortical neurons. RSV induced AMPK phosphorylation and inhibited mTOR phosphorylation. Inhibition of AMPK phosphorylation using compound C prevented resveratrol-induced down-regulation of tPA activity. This suggested that AMPK/mTOR-dependent translational inhibition contributes to the down-regulation of the tPA. Under glutamate-stimulated conditions of rat primary cortical neurons, tPA activity and expression were increased along with increased tPA mRNA expression but afterward treatment of RSV inhibited the glutamate-induced increase in tPA activity and expression and tPA mRNA expression. Glutamate stimulation induced activation of Akt and MAPK pathways as well as mTOR which were inhibited by RSV. Interestingly, the Erk pathway inhibitor U0126, but neither PI3K-Akt inhibitor LY294002 nor p38 inhibitor SB203580, mimicked the inhibitory action of RSV on glutamate-induced tPA up-regulation. This suggested the essential role of Erk in the transcriptional up-regulation of tPA expression, which is targeted by RSV. Glutamate stimulation induced neuronal cell death as determined by PI staining and MTT assay. However, RSV protected the cultured rat primary cortical neurons from glutamate-induced cell death as paralleled with the changes in tPA expression. These results suggested that RSV can modulate tPA activity under basal and stimulated conditions by both translational and transcriptional mechanisms. The regulation of the tPA by RSV provides additional therapeutic targets on top of the growing number of molecular substrates of RSV's action in the brain.

Abstract
PURPOSE In the pathogenesis of diabetic retinopathy, matrix metalloproteinase (MMP)-9 damages retinal mitochondria, activating the apoptotic machinery. Transcription of MMP-9 is regulated by nuclear factor kappa B (NF-κB), and the activation of NF-κB is modulated by the acetylation of its p65 subunit. Sirtuin 1 (Sirt1), a deacetylase, plays an important role in the acetylation-deacetylation of p65. The goal of this study is to investigate the role of Sirt1 in the activation of MMP-9 in diabetic retinopathy. METHODS The effect of hyperglycemia and Sirt1 activator, resveratrol, on acetylation of p65 and its binding at MMP-9 promoter-and mitochondrial damage and apoptosis-was assessed in the retinal endothelial cells. Role of oxidative stress in the regulation of Sirt1 was evaluated in the cells incubated in H2O2. The results were confirmed in the retina from diabetic mice with Sod2 or MMP-9 gene manipulated. RESULTS High glucose decreased Sirt1 activity and increased p65 acetylation, and resveratrol prevented increase in p65 acetylation, binding of p65 at MMP-9 promoter and MMP-9 activation, mitochondria damage, and cell apoptosis. While Sirt1 was decreased by H2O2, MMP-9 was significantly increased. Retina from wild-type diabetic mice presented similar decrease in Sirt1, and diabetic mice with Sod2 overexpression or MMP-9 deletion had normal retinal Sirt1. Retinal microvasculature from human donors with established diabetic retinopathy also had decreased Sirt1. CONCLUSIONS Thus, in diabetes, increase in oxidative stress inhibits Sirt1 and p65 is hyperacetylated, increasing the binding of p65 at MMP-9 promoter. Prevention of Sirt1 inhibition, via modulating acetylation of p65, should protect activation of MMP-9 and inhibit the development of diabetic retinopathy.

Abstract
Sirtuin 1 (SIRT1) regulates inflammation, aging (life span and health span), calorie restriction/energetics, mitochondrial biogenesis, stress resistance, cellular senescence, endothelial functions, apoptosis/autophagy, and circadian rhythms through deacetylation of transcription factors and histones. SIRT1 level and activity are decreased in chronic inflammatory conditions and aging, in which oxidative stress occurs. SIRT1 is regulated by a NAD(+)-dependent DNA repair enzyme, poly(ADP-ribose) polymerase-1 (PARP1), and subsequent NAD(+) depletion by oxidative stress may have consequent effects on inflammatory and stress responses as well as cellular senescence. SIRT1 has been shown to undergo covalent oxidative modifications by cigarette smoke-derived oxidants/aldehydes, leading to posttranslational modifications, inactivation, and protein degradation. Furthermore, oxidant/carbonyl stress-mediated reduction of SIRT1 leads to the loss of its control on acetylation of target proteins including p53, RelA/p65, and FOXO3, thereby enhancing the inflammatory, prosenescent, and apoptotic responses, as well as endothelial dysfunction. In this review, the mechanisms of cigarette smoke/oxidant-mediated redox posttranslational modifications of SIRT1 and its roles in PARP1 and NF-κB activation, and FOXO3 and eNOS regulation, as well as chromatin remodeling/histone modifications during inflammaging, are discussed. Furthermore, we have also discussed various novel ways to activate SIRT1 either directly or indirectly, which may have therapeutic potential in attenuating inflammation and premature senescence involved in chronic lung diseases.

Abstract
The development of acute lung injury (ALI) during sepsis almost doubles the mortality rate of patients. The efficacy of current treatment strategies is low as treatment is usually initiated following the onset of symptoms. Inflammation is one of the main mechanisms of autoimmune disorders and is a common feature of sepsis. The suppression of inflammation is therefore an important mechanism for the treatment of sepsis. Sirtuin 1 (Sirt1) has been demonstrated to play a role in the regulation of inflammation. Resveratrol, a potent Sirt1 activator, exhibits anti‑inflammatory properties. However, the role of resveratrol for the treatment of ALI during sepsis is not fully understood. In the present study, the anti‑inflammatory role of Sirt1 in the lipopolysaccharide (LPS)‑induced TC‑1 cell line and its therapeutic role in ALI was investigated in a mouse model of sepsis. The upregulation of matrix metalloproteinase-9, interleukin (IL)‑1β, IL‑6 and inducible nitric oxide synthase was induced by LPS in the mouse model of sepsis and the TC‑1 cell line, and resveratrol suppressed the overexpression of these proinflammatory molecules in a dose‑dependent manner. Resveratrol decreased pulmonary edema in the mouse model of sepsis induced by LPS. In addition, resveratrol improved lung function and reduced pathological alterations in the mouse model of sepsis. Knockdown of Sirt1 by RNA interference resulted in an increased susceptibility of TC‑1 cells to LPS stimulation and diminished the anti‑inflammatory effect of resveratrol. These results demonstrated that resveratrol inhibits LPS‑induced ALI and inflammation via Sirt1, and indicated that Sirt1 is an efficient target for the regulation of LPS‑induced ALI and inflammation. The present study provides insights into the treatment of ALI during sepsis.

Abstract
Trans-3,4',5-trihydroxystilbene (resveratrol) is a grape polyphenol present in various plants, food products, red wine and grapes. Resveratrol has anti-inflammatory, anticarcinogenic, anti-oxidant and anti-aging properties. Matrix metalloproteinases (MMPs) are key enzymes involved in the degradation of the extracellular matrix, and their expression may be regulated in cancer metastasis. In the present study, we aimed to evaluate the effect of resveratrol on MMPs and cell migration, and to understand the mechanism of action in HT1080 human fibrosarcoma cells. We found that resveratrol inhibited HT1080 cell viability at various concentrations as detected by the MTT assay and FACS analysis. However, resveratrol dramatically increased the activation and expression of MMP-9 in a dose- and time-dependent manner, as determined by gelatin zymography assay and western blot analysis. We also discovered that resveratrol enhanced the migratory ability of HT1080 cells, as determined by the wound healing assay, and decreased the phosphorylation of p38 kinase. Moreover, the Akt kinase was inhibited by resveratrol in the HT1080 cells. The inhibition of p38 and Akt kinases with SB203580 and LY294002 further increased resveratrol-induced MMP-9 as well as cell migration in the HT1080 cells. Our results suggest that resveratrol regulates MMP-9 and migratory abilities through the p38 kinase and PI-3K pathways in HT1080 human fibrosarcoma cells.

Mediterranean diet polyphenols reduce inflammatory angiogenesis through MMP-9 and COX-2 inhibition in human vascular endothelial cells: a potentially protective mechanism in atherosclerotic vascular disease and cancer.

Abstract
Diets with high content of antioxidant polyphenols are associated with low prevalence of cardiovascular diseases and cancer. Inflammatory angiogenesis is a key pathogenic process both in cancer and atherosclerosis, and is tightly regulated by the proinflammatory enzyme cyclooxygenase (COX)-2 and the matrix degrading enzymes matrix metalloproteinases (MMPs). We studied the effects of antioxidant polyphenols from virgin olive oil (oleuropein and hydroxytyrosol) and red wine (resveratrol and quercetin) on endothelial cell angiogenic response in vitro, and explored underlying mechanisms. Cultured endothelial cells were pre-incubated with 0.1-50 μmol/L polyphenols before stimulation with phorbol myristate acetate (PMA). All tested polyphenols reduced endothelial cell tube formation on matrigel and migration in wound healing assays. The reduced angiogenesis was associated with the inhibition of PMA-induced COX-2 protein expression and prostanoid production, as well as MMP-9 protein release and gelatinolytic activity. These effects were accompanied by a significant reduction in the stimulated intracellular reactive oxygen species levels and in the activation of the redox-sensitive transcription factor nuclear factor (NF)-κB. Our findings reveal that olive oil and red wine polyphenols reduce inflammatory angiogenesis in cultured endothelial cells, through MMP-9 and COX-2 inhibition, supporting a potential protective role for dietary polyphenols in atherosclerotic vascular disease and cancer.

Abstract
In the field of herpesvirus research, the exact molecular mechanism by which such viruses reactivate from latency remains elusive. Kaposi's sarcoma-associated herpesvirus (KSHV) primarily exists in a latent state, while only 1–3% of cells support lytic infection at any specific time. KSHV reactivation from latency is an exceedingly intricate process mediated by the integration of viral and cellular factors. Previously, our lab has described early growth response-1 (Egr-1) as an essential component for the KSHV reactivation process via its ability to mediate transcription of KSHV ORF50, the gene encoding for replication and transcription activator (RTA), a viral component known to control the switch from latent to lytic infection. In here, electrophoretic mobility shift assays (EMSA) and chromatin immunoprecipitation (ChIP) experiments revealed that Egr-1 binds KSHV ORF50 promoter (ORF50P) in at least two different GC-rich binding domains. Expression profiles of cellular egr-1 and KSHV-encoded ORF50 follow a similar pattern during de novo KSHV infection. Over-expressing Egr-1, a signaling component downstream of Raf>MEK>ERK1/2, in KSHV-infected cells activates KSHV lytic replication. Through performing more physiologically relevant experiments, we analyzed the effect of a dietary supplement containing resveratrol on KSHV-infected cells. Our results, for the first time, demonstrate resveratrol to act in lowering ERK1/2 activity and expression of Egr-1 in KSHV-infected cells, resulting in the suppression of virus reactivation from latency. Taken together, these findings will undoubtedly contribute to future studies on not only combating KSHV related disease conditions, but also on other herpesviruses-induced pathogenesis.

Abstract
This review emphasizes the effects of resveratrol on factors involved in the mechanism of atherosclerosis and risk factors for atherosclerosis. The effects of wine and resveratrol on atherosclerosis are also discussed. Resveratrol is a potent antioxidant and an anti-inflammatory agent. It reduces the expression of cell adhesion molecules, monocyte colony stimulating factors, matrix metalloproteinases, and growth factors; and inhibits platelet aggregation and vascular smooth muscle cell proliferation. It reduces the serum levels of total cholesterol, triglycerides (TG), and raises high-density lipoprotein cholesterol, inhibits expression of C-reactive protein and lowers the levels of advanced glycation end products and its receptor in the vascular tissue. It lowers the risk factors for plaque rupture. Epidemiological data show that moderate consumption of alcohol has an inverse association with carotid atherosclerosis while high consumption has a positive association with carotid atherosclerosis. Wine reduces the extent of atherosclerosis in animal model. The antiatherosclerotic effect of wine is mainly due to it resveratrol content. Resveratrol reduces the extent of atherosclerosis in animal model of atherosclerosis (apolipoprotein [Apo] E-deficient and Apo E(-/-)/low-density lipoprotein receptor-deficient mice and macrophage). In rabbit model of atherosclerosis, both reduction and acceleration of atherosclerosis have been reported with resveratrol. There are no data for regression and slowing of progression of atherosclerosis. Robust clinical trials for suppression of atherosclerosis are lacking. In conclusion, resveratrol has potential but experimental studies in depth and robust clinical trials are lacking for this agent to be of any value in the primary and secondary prevention of coronary and peripheral artery disease.

Abstract
Inflammation is one of main mechanisms of autoimmune disorders and a common feature of most diseases. Appropriate suppression of inflammation is a key resolution to treat the diseases. Sirtuin1 (Sirt1) has been shown to play a role in regulation of inflammation. Resveratrol, a potent Sirt1 activator, has anti-inflammation property. However, the detailed mechanism is not fully understood. In this study, we investigated the anti-inflammation role of Sirt1 in NIH/3T3 fibroblast cell line. Upregulation of matrix metalloproteinases 9 (MMP-9), interleukin-1beta (IL-1β), IL-6 and inducible nitric oxide synthase (iNOS) were induced by tumor necrosis factor alpha (TNF-α) in 3T3 cells and resveratrol suppressed overexpression of these pro-inflammatory molecules in a dose-dependent manner. Knockdown of Sirt1 by RNA interference caused 3T3 cells susceptible to TNF-α stimulation and diminished anti-inflammatory effect of resveratrol. We also explored potential anti-inflammatory mechanisms of resveratrol. Resveratrol reduced NF-κB subunit RelA/p65 acetylation, which is notably Sirt1 dependent. Resveratrol also attenuated phosphorylation of mammalian target of rapamycin (mTOR) and S6 ribosomal protein (S6RP) while ameliorating inflammation. Our data demonstrate that resveratrol inhibits TNF-α-induced inflammation via Sirt1. It suggests that Sirt1 is an efficient target for regulation of inflammation. This study provides insight on treatment of inflammation-related diseases.

Abstract
The advent of nanotechnology has had a revolutionary impact on many aspects of 21st century life. Nanotechnology has provided an opportunity to explore new avenues that conventional technologies have been unable to make an impact on for diagnosis, prevention, and therapy of different diseases, and of cancer in particular. Entities in nanometer sizes are excellent platforms to incorporate various drugs or active materials that can be delivered effectively to the desired action site without compromising the activity of the incorporated drug or material. In particular, nanotechnology entities can be used to deliver conventional natural products that have poor solubility or a short half life. Conventional natural products used with entities in nanometer sizes enable us to solve many of the inherent problems (stability, solubility, toxicity) associated with natural products, and also provide a platform for targeted delivery to tumor sites. We recently introduced the novel concept of using nanotechnology for enhancing the outcome of chemoprevention, which we called ‘nanochemoprevention’. This idea was subsequently exploited by several laboratories worldwide and has now become an advancing field in chemoprevention research. This review examines some of the applications of nanotechnology for cancer prevention and therapy using natural products.
