Abstract
Inflammation is a response to various injuries, illnesses, and severe trauma. The primary function of inflammation is to combat pathogens, eliminate them from the body, and initiate wound healing. However, inflammation also contributes to numerous diseases, such as cancer, cardiovascular disease, diabetes, obesity, osteoporosis, rheumatoid arthritis, inflammatory bowel disease, and asthma. As the importance of nutrition in maintaining human health has become increasingly recognized, the consumption of natural antioxidants has gained popularity, especially in developed countries. A growing body of research has shown that consuming foods rich in lycopene can protect individuals from a range of conditions, including cancer, heart disease, and other diseases. As a result, lycopene is gaining recognition as a potential protective antioxidant in the fields of medicine and pharmacology. This review aims to highlight the effects of lycopene on inflammatory diseases and provide a foundational understanding for researchers interested in further research on lycopene.

Lycopene Inhibits IL-6 Expression by Upregulating NQO1 and HO-1 via Activation of Nrf2 in Ethanol/Lipopolysaccharide-Stimulated Pancreatic Acinar Cells. Antioxidants (Basel) 2022; 11:antiox11030519. [PMID: 35326169 PMCID: PMC8944646 DOI: 10.3390/antiox11030519] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 03/05/2022] [Accepted: 03/07/2022] [Indexed: 12/16/2022] Open
Abstract
In alcoholic pancreatitis, alcohol increases gut permeability, which increases the penetration of endotoxins, such as lipopolysaccharides (LPS). LPS act as clinically significant triggers to increase pancreatic damage in alcoholic pancreatitis. Ethanol or LPS treatment increases reactive oxygen species (ROS) production in pancreatic acinar cells. ROS induce inflammatory cytokine production in pancreatic acinar cells, leading to pancreatic inflammation. The nuclear erythroid-2-related factor 2 (Nrf2) pathway is activated as a cytoprotective response to oxidative stress, and induces the expression of NAD(P)H quinone oxidoreductase 1 (NQO1) and heme oxygenase-1 (HO-1). Lycopene exerts anti-inflammatory and antioxidant effects in various cells. We previously showed that lycopene inhibits NADPH oxidase to reduce ROS and IL-6 levels, and zymogene activation in ethanol or palmitoleic acid-treated pancreatic acinar cells. In this study, we examined whether lycopene inhibits IL-6 expression by activating the Nrf2/NQO1-HO-1 pathway, and reducing intracellular and mitochondrial ROS levels, in ethanol and LPS-treated pancreatic AR42J cells. Lycopene increased the phosphorylated and nuclear-translocated Nrf2 levels by decreasing the amount of Nrf2 sequestered in the cytoplasm via a complex formation with Kelch-like ECH1-associated protein 1 (Keap1). Using exogenous inhibitors targeting Nrf2 and HO-1, we showed that the upregulation of activated Nrf2 and HO-1 results in lycopene-induced suppression of IL-6 expression and ROS production. The consumption of lycopene-rich foods may prevent the development of ethanol and LPS-associated pancreatic inflammation by activating Nrf2-mediated expression of NQO1 and HO-1, thereby decreasing ROS-mediated IL-6 expression in pancreatic acinar cells.

Abstract
High alcohol intake results in the accumulation of non-oxidative ethanol metabolites such as fatty acid ethyl esters (FAEEs) in the pancreas. High FAEE concentrations mediate pancreatic acinar cell injury and are associated with alcoholic pancreatitis. Treatment with ethanol and the fatty acid palmitoleic acid (EtOH/POA) increased the levels of palmitoleic acid ethyl ester and induced zymogen activation and cytokine expression in pancreatic acinar cells. EtOH/POA induces nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-mediated reactive oxygen species (ROS) production and pancreatic acinar cell injury. Lycopene, a bright-red carotenoid, is a potent antioxidant due to its high number of conjugated double bands. This study aimed to investigate whether lycopene inhibits the EtOH/POA-induced increase in ROS production, zymogen activation, and expression of the inflammatory cytokine IL-6 in EtOH/POA-stimulated pancreatic acinar AR42J cells. EtOH/POA increased the ROS levels, NADPH oxidase and NF-κB activities, zymogen activation, IL-6 expression, and mitochondrial dysfunction, which were inhibited by lycopene. The antioxidant N-acetylcysteine and NADPH oxidase 1 inhibitor ML171 suppressed the EtOH/POA-induced increases in ROS production, NF-κB activation, zymogen activation, and IL-6 expression. Therefore, lycopene inhibits EtOH/POA-induced mitochondrial dysfunction, zymogen activation, and IL-6 expression by suppressing NADPH oxidase-mediated ROS production in pancreatic acinar cells.

Abstract
Autophagy is an evolutionarily conserved process that degrades damaged organelles and recycles macromolecules to support cell survival. However, in certain disease states, dysregulated autophagy can play an important role in cell death. In pancreatitis, the accumulation of autophagic vacuoles and damaged mitochondria and premature activation of trypsinogen are shown in pancreatic acinar cells (PACs), which are the hallmarks of impaired autophagy. Oxidative stress mediates inflammatory signaling and cytokine expression in PACs, and it also causes mitochondrial dysfunction and dysregulated autophagy. Thus, oxidative stress may be a mediator for autophagic impairment in pancreatitis. Lycopene is a natural pigment that contributes to the red color of fruits and vegetables. Due to its antioxidant activity, it inhibited oxidative stress-induced expression of cytokines in experimental models of acute pancreatitis. Lycopene reduces cell death through the activation of 5′-AMP-activated protein kinase-dependent autophagy in certain cells. Therefore, lycopene may ameliorate pancreatitis by preventing oxidative stress-induced impairment of autophagy and/or by directly activating autophagy in PACs.

Abstract
INTRODUCTION Rotational shift work has a considerable effect on immune function and cause inflammation. In addition, it may lead to unhealthy dietary intake. No earlier study has examined the association between dietary patterns and inflammation in rotational shift workers. Therefore, this study was conducted to investigate the association between dietary patterns and circulating proinflammatory cytokines among shift workers. METHODS This cross-sectional study was conducted among 257 male shift workers. Dietary intake of participants was examined using the semiquantitative Food Frequency Questionnaire. Serum concentrations of interleukin-6 (IL-6), tumour necrosis factor-α (TNF-α) and high sensitivity C-reactive protein (hs-CRP) were measured using suitable commercial kits. RESULTS Three main dietary patterns included green vegetables, yellow vegetables and cruciferous vegetables (VEG), liquid oils and mayonnaise, fast food and eggs (LFE), as well as tea and coffee, refined grains and spice (TRS). Subjects with the highest adherence to VEG dietary pattern had a significantly lower concentration of IL-6 (p<0.01) and TNF-α (p<0.001) as compared with those with the lowest adherence. On the other hand, a significant negative association was found between LFE dietary pattern and serum concentrations of IL-6 (p=0.01) and TNF-α (p=0.02). However, no significant association was found between adherence to VEG (p=0.34) or LFE (p=0.99) dietary patterns and levels of hs-CRP and between adherence to TRS dietary pattern and any of the inflammatory cytokines. CONCLUSION Adherence to VEG and LFE dietary patterns was inversely and directly associated to serum IL-6 and TNF-α concentrations in shift workers, respectively. However, no significant association was found between adherence to these two dietary patterns and serum hs-CRP concentrations and between TRS dietary pattern and any of the inflammatory cytokines.

Abstract
In order to discover new drug delivery approaches and to understand the mechanism of iron overload in cerebral ischemia/reperfusion (I/R), we aimed to investigate the effects of lycopene (LYC) in the form of nano-liposomes (L-LYC) on iron-regulating proteins and ischemic brain injury. We found that L-LYC significantly increased the LYC content in serum and the brain. Adult male Sprague-Dawley rats treated with L-LYC for 14 days were subjected to 60 min of ischemia and 7 days of reperfusion. The effects of L-LYC were evaluated by infarction volume, neurological score, neuronal apoptosis, and markers for oxidative stress. Levels of iron-regulating protein such as hepcidin and ferroportin (FPN1) were examined. L-LYC reduced cerebral infarction and improved neurobehavior of the rats more efficiently than "naked" LYC. L-LYC reduced protein levels of oxidases (e.g. nitric oxide synthase and NOX2), increased the level of Bcl-2, lowered caspase-3, and suppressed apoptosis through inhibiting MAPK-JNK. Furthermore, L-LYC suppressed hepcidin-mediated decrease in FPN1, a sole iron exporter, and normalized the levels of iron. We further demonstrated that the effect of L-LYC on hepcidin expression might result from its ability to attenuate the release of the inflammatory factor interleukin 6. The results demonstrated that nano-liposomal encapsulation significantly improved LYC efficacy in providing neuronal protection against I/R injury. The data also revealed a novel mechanism of L-LYC's neuroprotection by regulating iron metabolism in an ischemic brain.

Abstract
Carotenoids and retinoids have several similar biological activities such as antioxidant properties, the inhibition of malignant tumour growth and the induction of apoptosis. Supplementation with carotenoids can affect cell growth and modulate gene expression and immune responses. Epidemiological studies have shown a correlation between a high carotenoid intake in the diet with a reduced risk of breast, cervical, ovarian, colorectal cancers, and cardiovascular and eye diseases. Cancer chemoprevention by dietary carotenoids involves several mechanisms, including effects on gap junctional intercellular communication, growth factor signalling, cell cycle progression, differentiation-related proteins, retinoid-like receptors, antioxidant response element, nuclear receptors, AP-1 transcriptional complex, the Wnt/β-catenin pathway and inflammatory cytokines. Moreover, carotenoids can stimulate the proliferation of B- and T-lymphocytes, the activity of macrophages and cytotoxic T-cells, effector T-cell function and the production of cytokines. Recently, the beneficial effects of carotenoid-rich vegetables and fruits in health and in decreasing the risk of certain diseases has been attributed to the major carotenoids, β-carotene, lycopene, lutein, zeaxanthin, crocin (/crocetin) and curcumin, due to their antioxidant effects. It is thought that carotenoids act in a time- and dose-dependent manner. In this review, we briefly describe the biological and immunological activities of the main carotenoids used for the treatment of various diseases and their possible mechanisms of action.

Abstract
Overweight and obese individuals have an increased risk of developing the metabolic syndrome because of subsequent chronic inflammation and oxidative stress, which the antioxidant nutrient lycopene can reduce. However, studies indicate that different BMI statuses can alter the positive effects of lycopene. Therefore, the purpose of this study was to examine how BMI influences the association between serum lycopene and the metabolic syndrome. The tertile rank method was used to divide 13 196 participants, aged 20 years and older, into three groups according to serum concentrations of lycopene. The associations between serum lycopene and the metabolic syndrome were analysed separately for normal-weight, overweight and obese participants. Overall, the prevalence of the metabolic syndrome was significantly higher in the first tertile group (OR 38·6%; 95% CI 36·9, 40·3) compared with the second tertile group (OR 29·3%; 95% CI 27·5, 31·1) and the third tertile group (OR 26·6%; 95% CI 24·9, 28·3). However, the associations between lycopene and the metabolic syndrome were only significant for normal-weight and overweight participants (P0·05), even after adjusting for possible confounding variables. In conclusion, BMI appears to strongly influence the association between serum lycopene and the metabolic syndrome.

Abstract
Many inflammatory chemokines release from leukocytes and pancreatic acinar cells which play important roles in pathophysiology of acute pancreatitis (AP). Of interests, CXCL2 and CCL2 have been shown elevated in the plasma of patients with AP. We have recently found that Glycyrrhizin (GZ) attenuates AP in mice model. In this study, we aimed to investigate the direct effect of GZ on expression levels of CCL2 and CXCl2 in isolated pancreatic acinar cells. Isolated acinar cells were isolated from the pancreas of healthy C57BL/6 mice, stimulated with cerulein (10(-7) M) and then treated with either PBS or different doses of GZ. The levels of CCL2 and CXCL2 expression at mRNA were assessed by qRT-PCR. Conditioned media from supernatants of each cells culture condition were collected for detection of CCL2 and CXCL2 levels by ELISA. First, we observed that cerulein significantly upregulates both cytokines expression in acinar cells. Moreover, we treated the acinar cells with GZ and found that GZ significantly downregulates CCL2 and CXCL2 expression at mRNA levels in a dose-dependent manner. Consistently, the conditioned media of GZ-treated cells contained a significant lower levels of CCL2 and CXCL2 (p<0.05). In conclusion, our data demonstrate for the first time that GZ directly downregulates CCL2 and CXCL2 levels in cerulein-stimulated acinar cells which may explain the mechanism of therapeutic effects of GZ in cerulein-induced AP in mice.

Abstract
This study investigated the anti-oxidative and anti-inflammatory effects of lycopene on severe acute pancreatitis (SAP) in both in vivo and in vitro models. Utilizing a rat model, we found that lycopene administration protected against SAP, as indicated by the decreased levels of serum amylase and C-reactive protein. Pathological changes were alleviated by pretreatment with lycopene. The serum levels of tumor necrosis factor-α, interleukin-6, macrophage inflammatory protein-1α, and monocyte chemotactic protein-1 were decreased by lycopene. The decreased reactive oxygen species (ROS) content in the pancreatic tissues of the lycopene-treated group were indirectly evaluated by measuring the levels of myeloperoxidase, lipid peroxidase, and superoxide dismutase. Lycopene protected acinar cells against necrosis and apoptosis by relieving the mitochondrial and endoplasmic stress caused by ROS which was shown in electron microscopy and immunohistochemistry staining of active nuclear factor-κB p65. The protective effect was also observed in a simulated SAP model in a rat acinar cell line. ROS and apoptotic staining were compared between groups. Lycopene exerts protective effects against SAP in rats that may be related to its anti-inflammatory property through inhibiting the expression of damage-associated molecular patterns, and anti-oxidative property which can thus maintain cellular homeostasis and prevent the phosphorylation of JNK pathway.

Abstract
BACKGROUND Oxidative stress is recognized as a pivotal effector of several pathogenic processes, including acute pancreatitis. Reactive oxygen species not just cause damage on the main cellular components, but also influence the expression of antioxidant system genes. Antioxidant molecules, such as melatonin, could be good candidates for the treatment of this multidimensional disease. The present study was to evaluate the chemopreventive effect of melatonin in a rat model of cerulein-induced acute pancreatitis. METHODS Four subcutaneous injections of cerulein (20 μg/kg body weight) were given to Wistar rats at two hours intervals; melatonin was injected intraperitoneally (25 mg/kg body weight) 30 minutes before each injection of cerulein. Lipid peroxidation, protein oxidation (carbonyl groups), total antioxidant status, and glutathione peroxidase activity were determined in pancreatic tissue using commercial kits. RESULTS The chemopreventive administration of melatonin caused a reduction in lipid peroxidation and protein oxidation due to injections of cerulein. Additionally, melatonin treatment was also able to revert glutathione peroxidase activity and total antioxidant status near to control levels, suggesting that melatonin could prevent from oxidative phenomena in the pancreas, such as lipid peroxidation and protein oxidation, and could stimulate, directly or indirectly, the expression of antioxidant enzymes. CONCLUSION Melatonin, a polyvalent antioxidant, protected the pancreatic damage via the decrease of oxidative stress and increase of the activities of antioxidant enzymes in cerulein-induced acute pancreatitis.

Diets rich in fruits and vegetables suppress blood biomarkers of metabolic stress in overweight women. Prev Med 2012; 54 Suppl:S109-15. [PMID: 22226662 DOI: 10.1016/j.ypmed.2011.12.026] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2011] [Revised: 12/17/2011] [Accepted: 12/20/2011] [Indexed: 11/22/2022]
Abstract
OBJECTIVE This study was performed to evaluate the effects of high vegetable-fruit (high-VF) and low vegetable-fruit (low-VF) diet on surrogate biomarkers of adiposity-related metabolic disturbances. METHODS Overweight women (n=22, 19-29 years) participated in the study between July and August, 2007 in Seoul, Korea. The intervention consisted of either high-VF diet (12 servings of VF/day) or low-VF diet (2 servings of VF/day). Plasma concentration of carotenoids and biomarkers of inflammation and oxidative stress were determined before and after each intervention period. RESULTS Study results indicated that body fat content is positively correlated with plasma interleukin (IL)-6, C-reactive protein (CRP), and leptin concentrations at baseline. Oxidative DNA damage and lipopolysaccharide (LPS)-activated production of IL-1β and IL-6 in peripheral blood mononuclear cells (PBMCs) were decreased with high-VF diet while low-VF diet increased those markers. Changes in the concentration of plasma total carotenoid and β-carotene were inversely correlated with change in plasma IL-1β concentration. Differences in IL-β production in LPS-activated PBMCs were inversely correlated with changes in plasma concentration of lutein-zeaxanthin. Also, changes in plasma total carotenoid and lycopene concentration were inversely correlated with the changes in IL-6 production in LPS-activated PBMCs. CONCLUSION Daily intake of vegetables and fruits can modify adiposity-related metabolic disturbances.

Abstract
Interleukin 6 (IL-6) is considered a major indicator of the acute-phase inflammatory response. Endometriosis and pelvic inflammation, diseases that manifest elevated levels of IL-6, are commonly associated with higher infertility. However, the mechanistic link between elevated levels of IL-6 and poor oocyte quality is still unclear. In this work, we explored the direct role of this cytokine as a possible mediator for impaired oocyte spindle and chromosomal structure, which is a critical hurdle in the management of infertility. Metaphase-II mouse oocytes were exposed to recombinant mouse IL-6 (50, 100 and 200 ng/mL) for 30 minutes and subjected to indirect immunofluorescent staining to identify alterations in the microtubule and chromosomal alignment compared to untreated controls. The deterioration in microtubule and chromosomal alignment were evaluated utilizing both fluorescence and confocal microscopy, and were quantitated with a previously reported scoring system. Our results showed that IL-6 caused a dose-dependent deterioration in microtubule and chromosomal alignment in the treated oocytes as compared to the untreated group. Indeed, IL-6 at a concentration as low as 50 ng/mL caused deterioration in the spindle structure in 60% of the oocytes, which increased significantly (P<0.0001) as IL-6 concentration was increased. In conclusion, elevated levels of IL-6 associated with endometriosis and pelvic inflammation may reduce the fertilizing capacity of human oocyte through a mechanism that involves impairment of the microtubule and chromosomal structure.

[PMID: 22178412 DOI: 10.1016/j.freeradbiomed.2011.11.010] [Citation(s) in RCA: 44] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2011] [Revised: 11/07/2011] [Accepted: 11/10/2011] [Indexed: 01/09/2023]
Abstract
Oxidative stress linked to DNA damage is involved in the pathogenesis of Helicobacter pylori-associated gastric diseases. The DNA damage response (DDR) coordinates cell-cycle transitions, DNA repair, and apoptosis through the activation of ataxia-telangiectasia-mutated (ATM) and ATM and Rad3-related (ATR) and their target proteins. However, neither H. pylori-induced DDR nor the effects of antioxidants on the DNA damage have been established. This study aimed to investigate the detailed process of H. pylori-induced DNA damage and to examine whether lycopene, a natural antioxidant, inhibits DNA damage and cellular response of gastric epithelial AGS cells infected with H. pylori. AGS cells were cultured with H. pylori in Korean isolates and treated with or without lycopene. Cell viability, DNA damage indices, levels of 8-OH-dG, and reactive oxygen species (ROS) as well as cell-cycle distributions were determined. The activation of ATM, ATR, Chk1, and Chk2; histone H2AX focus formation; activation and induction of p53; and levels of Bax and Bcl-2 and poly(ADP-ribose) polymerase-1 (PARP-1) were assessed. The results showed that H. pylori induced apoptosis in AGS cells with increased Bax and decreased Bcl-2 expression as well as PARP-1 cleavage. Culture with H. pylori led to increases in intracellular ROS, 8-OH-dG, double-strand DNA breaks (DSBs), and DNA fragmentation. H. pylori induced activation of the ATM/Chk2 and ATR/Chk1 pathways, phosphorylation of H2AX and p53, and a delay in the progression of the cells entering the S phase. Lycopene inhibited H. pylori-induced increases in ROS, apoptosis, alterations in cell-cycle distribution, DSBs, and ATM- and ATR-mediated DDR in AGS cells. In conclusion, lycopene may be beneficial for treatment of H. pylori-induced gastric diseases associated with oxidative DNA damage.

Abstract
AIM: To investigate the mechanism of action of suppressor of cytokine signaling 3 (SOCS3) in experimental severe acute pancreatitis (SAP) in rats.
METHODS: A rat model of SAP was reproduced by retrograde injection of 4% sodium taurocholate into the biliopancreatic duct. Thirty-two male SD rats were randomly and equally assigned into four groups: normal control group (NC) and three SAP groups (6, 12 and 18 h). Serum amylase (AMY) was measured dynamically. Pathological changes in the pancreas and lung were observed under a light microscope. The concentrations of IL-6 and IL-18 were determined by ELISA. The localization and expression of SOCS3 protein in the pancreas were detected by immunohistochemical staining and Western blotting.
RESULTS: Compared to the NC group, serum level of AMY increased significantly in the three SAP groups (2675.18 ± 278.32, 3541.15 ± 215.43, 4568.89 ± 357.86 vs 651.38 ± 52.94, all P < 0.05). Pancreatic injuries revealed under a light microscope were gradually aggravated with disease progression. Serum concentrations of IL-6 and IL-18 in the SAP groups increased significantly compared to the NC group (all P < 0.05). The levels of SOCS3 protein in the SAP groups increased significantly compared to the NC group (all P < 0.05). The changes in SOCS3 protein expression were correlated with the severity of pancreatic injury and serum concentrations of IL-6 and IL-18.
CONCLUSION: SOCS3 plays an important role in inhibiting inflammatory reaction in rats with SAP.

Abstract
Reactive oxygen species (ROS) are important mediators to induce pancreatitis. Serum levels of antioxidant enzymes and carotenoids including lycopene are lower in patients with pancreatitis than those of healthy subjects. The cholecystokinin (CCK) analog cerulein induces similar pathologic events as shown in human pancreatitis. Recent studies show that high doses of cerulein activate NF-κB and induce the expression of inflammatory cytokines, in pancreatic acinar cells, which is mediated by the activation of NADPH oxidase. Lycopene functions as a very potent antioxidant to suppress the induction of inflammatory cytokines, in pancreatic acinar cells stimulated with cerulein. In this review, the possible beneficial effect of lycopene on experimental pancreatitis shall be discussed based on its antioxidant activity.
