Misaki Ono, ... Shuji Nakano, in The Enzymes, 2015. 7500+ companies worldwide approach us every year for their revenue growth inititatives. suggests two mechanisms: nonoxidative and oxidative. Description Lycopene extract from tomato is a dark-red viscous liquid. A multicenter 10-country European trial also showed that lycopene can reduce the risk of myocardial infarction. published a report showing that lycopene had no association with prostate cancer risk.28 In their report, an increase in lycopene serum concentration of 10 μg/dL was associated with a 7% decrease in prostate cancer detection via prostate specific antigen (PSA), but also was correlated with an increase in 8% of cancers detected without a biopsy sample.28 These conflicting findings led Kristal to suggest additional studies with lycopene before medical authorities can recommend it as a potential anticancer agent.28, The mechanism by which lycopene may prevent prostate cancer is still under investigation, but a review article by Johary et al. Lycopene is a natural compound that is found in bright red fruits and vegetables like tomatoes, watermelon, and grapefruit. It was shown that downregulation of hTERT gene expression in MCF-7 cells is largely due to epigenetic alterations in hTERT promoter, i.e., time-dependent hypomethylation (DNA methyl transferase inhibition) of hTERT promoter [66,92]. tÎ#KÁ$S50ªO:¬a¤Ž:ñIº{÷2ì§:mÖQÒK>ÅÙBkžvÊ ö­ÈV缑0‰þãT˜€— ½Ö6-ªü¡YWºÇe°ß¡´ß#r~‰màÃùËhø"X? Lycopene is also found to concentrate in the adrenal gland, testis, and prostate gland [31] (Fig. [98] L. Xinli and X. Jiuhong, "Meta-analysis of the association between dietary lycopene intake and ovarian cancer risk in postmenopausal women", Scientific Reports, vol.4, pp. This method was based on the observation that, during negative ion atmospheric pressure chemical ionization with collision-induced dissociation, … Page 2 of (9) 3. This review summarises current evidence on the effect of lycopene on serum lipid concentrations and blood pressure. In fact, DMC can induce the expression of promoter methylated genes without reversing DNA methylation, suggesting a possible synergistic induction mechanism of gene expression upon combining DMC with DNMT inhibitors [99]. Human organs store lycopene in varying degrees. Lycopene is found in high amounts in tomatoes but is also present in watermelons, pink grapefruits, apricots, and pink guavas. Tomato (Lycopersicon esculentum Mill.) DMC induces the expression of promoter methylated genes. Improper processing and storage including exposure to light and oxygen may alter the ratio of lycopene isomers or degrade lycopene entirely [27]. It is one of a number of pigments called carotenoids. 2, 4 The biochemistry of lycopene is unique because it has no pro-vitamin A activity, unlike many other carotenoids, such as alpha … Other sources of lycopene include papaya, watermelon, pink guava, and pink grapefruit. Interestingly, lycopene reactivated GSTP1 gene expression through reduced promoter methylation in MDA-MB-468 breast cancer cells [118]. Gislaine Francieli da Silva, ... Nara Lins Meira Quintão, in Bioactive Nutraceuticals and Dietary Supplements in Neurological and Brain Disease, 2015. These lipid-soluble compounds protect against photooxidation, harvest light for photosynthesis, and dissipate excess light energy absorbed by the antenna pigments. fruits: Determination of lycopene in tomato (Lycopersicon esculentum, Mill.) Only a few metabolites, such as 5,6-dihydroxy-5,6-dihydrolycopene, have been detected in human plasma. Figure 2. By continuing you agree to the use of cookies. A simple, rapid method for HPLC analysis of lycopene isomers. Before lycopene can be recommended as a cancer protective agent, further studies are needed to ensure that the apparent benefit from lycopene isn’t actually due to other nutrients present in foods high in lycopene content. However, isomerization of lycopene from all-trans to cis configuration by heat processing increases its bioavailability [2]. One cup (240 mL) of tomato juice provides approximately 23 mg of lycopene. Lycopene can be detected in human circulation and in tissues in both all-trans and cis forms. Analysis of lycopene in tomato (Lycopersicon esculentum, Mill.) Lycopene (from the neo-Latin Lycopersicum, the tomato species) is a bright red carotenoid hydrocarbon found in tomatoes and other red fruits and vegetables, such as red carrots, watermelons, grapefruits, and papayas, but it is not present in strawberries or cherries. As found with other data from classmates who also had Hunt’s brand tomato paste, this data is very similar. It is one of a number of pigments called carotenoids. When ingested in its natural trans form, lycopene is poorly absorbed [30]. Chris Hamilton, ... Kim O’Neill, in Cancer, 2014, Lycopene (also called rhodopurpurin or nonprovitamin A carotenoid) is a powerful antioxidant present in tomatoes and other vegetables and fruits. In the United States, men and women consume an average of 6.8 and 4.6 mg of lycopene/day, respectively [27]. The amount of lycopene present in processed tomato products is often much higher than fresh tomatoes given that processing is often involves concentration via water loss. published research on the role of tomato products in preventing prostate cancer and found that increased intake of these foods—cooked or raw—do provide some protection against prostate cancer when tomato product intake is high (10 or more servings per week).24,25 Other studies, however, failed to find a correlation between lycopene and prostate cancer.26 A possible explanation has recently been proposed for this inconsistency: Goodman and coworkers reported that different levels of expression of the XRCC1 gene—responsible for aiding in DNA damage repair—affects whether lycopene will decrease prostate cancer risk.27, However, Kristal et al. It’s the pigment that gives red and pink fruits, such as tomatoes, watermelons and pink grapefruit, their characteristic color. In the human eye, lycopene is present in the retinal pigment epithelium (RPE)-choroid, ciliary body, and iris. Lycopene is found in tomatoes, watermelons, red oranges, pink grapefruits, apricots, rosehips, and guavas. However, the protective effect of lycopene against various types of cancer is controversial because various studies have obtained conflicting results. E-mail address: bkishida@pw.usda.gov. However, lycopene does not induce any DNA demethylation in RARβ2 promoter in MDA-MB-468 or MCF-7 breast cancer cells. Abstract Lycopene is a carotenoid that has antioxidant properties and imparts the red pigment in some fruits and vegetables. EGCG decreased the levels of 5-methylcytosine, DNMTs activity, both mRNA and protein levels of DNMT1, DNMT3a, and DNMT3b [95]. In humans, lycopene absorption is in the range of 10%–30% with the remainder being excreted [36,39]. Lycopene is a naturally occurring chemical that gives fruits and vegetables a red color. Copyright © 2021 Elsevier B.V. or its licensors or contributors. As a result, this compound inhibits cell proliferation and induces apoptosis in cell culture and was found to reduce tumor growth in animal models of breast, lung, and prostate cancer [30]. Lycopene and lycopene supplementation can lower the risk of coronary artery disease, probably due to its excellent antioxidant properties. 1-8, 2011. Lycopene is a lipophilic red-colored carotenoid pigment, composed of eight isoprene units (octaprene) joined by regular head to tail bindings, except in the middle of the molecule where the binding is tail to tail, giving rise to a symmetric structure (Fig. It was shown that this elevation is associated with promoter demethylation by DNA demethylase. Lycopene, a naturally occurring red carotenoid pigment found in tomatoes, pink grapefruit, watermelon, and other fruits, is associated with many beneficial effects on human health. The foods rich in lycopene are usually tomato products, such as, catsup, tomato sources, tomato juice, etc., and some other fruit, such as watermelon. Lycopene is a naturally occurring compound that contributes to the red color of fruits and vegetables and is a carotenoid antioxidant. The consumption of tomato salsa with avocado (as lipid source) led to a 4.4-fold increase in lycopene absorption as compared with salsa without avocado [31]. In this chapter, these effects of lycopene and its derivatives are summarized, with a focus on in vitro studies. It is produced by vegetables and fruits, with tomatoes and processed tomato products being the most abundant sources [25,26]. 1). Green tea polyphenols like EGCG act as a potent anticancer compound against MCF-7 (ER+) and MDA-MB-231 (ER−) breast cancer cells by epigenetically regulating hTERT [92]. Richard T. Lee MD, in Integrative Medicine (Fourth Edition), 2018, Lycopene is a cancer-fighting antioxidant vitamin that gives tomatoes, strawberries, and watermelon their rosy color. It is believed that lycopene was absorbed by passive diffusion as lipids. Lycopene is an essential intermediate in the pathway for synthesis of the β-ionone ring-containing carotenoids such as β-carotene in plant tissues, and in most plant tissues it is present in only minor amounts. What is Lycopene. by HPLC & Vis-NIR spectroscopy Paperback – December 27, 2011 Betty K. Ishida. Lycopene is a very lipophilic molecule, and therefore, it must be solubilized to be absorbed from a food, first by emulsification in the gastric contents and then incorporation into mixed micelles in the duodenum as facilitated by bile acid surfactants and lipases. Although lycopene is chemically a carotene, it has no vitamin A activity. Nurşen Başaran, ... A. Ahmet Başaran, in Gastrointestinal Tissue, 2017. Lycopene bioavailability can be affected by many factors such as food processing and dietary composition. Non-linear dose-response analysis did not show any significant effects of lycopene dosage (P non-linearity = 0.50) and duration of the intervention (P non-linearity = 0.63) on serum levels of PSA. It is suggested that lycopene may undergo in vivo oxidation to form epoxides, which then may be converted to the polar 5,6-dihydoxy-5,6-dihydrolycopene through metabolic reduction [38]. When salads were consumed without fat in the same study, no measurable lycopene uptake occurred [30]. Global top 2000 strategist rely on us for their growth strategies. [99] V. Bohm," Lycopene and human health", Lycocard Project, 2015, Germany. Lycopene is found abundantly in red fruits and vegetables, including tomato, watermelon, pink grapefruit, apricots, pink guava, and papaya [24]. 2, 4, 5 It consists of only hydrogen and carbon atoms, and is 1 of 600 carotenoids synthesized by plants and photosynthetic microorganisms. 2). Competition by other carotenoids or cholesterol may also influence lycopene absorption [10]. Lycopene source and tissue distribution. Processing raw tomatoes using heat (e.g., in the making of tomato juice, tomato paste, or ketchup) transforms natural lycopene to a form that is easier to utilize by the human body. Many studies suggested that lycopene absorption may be facilitated by other transporters, but this has not been confirmed yet [32,33]. is one of the predominant lycopene sources in a typical North American diet. Lycopene is a potent antioxidant, and thus, has application in various industries such as food, beverage, dietary supplement, functional foods, animal nutrition, cosmetics, and pharmaceutical.

Accuracy was validated by spiked blank analysis, and precision by performing replicate analysis. These results indicated hormone dependent action of lycopene in prostate cancer cells. Furthermore, the molecular mechanisms behind the actions of lycopene on human RPE cells, and the potential beneficial effects of lycopene in the prevention and treatment of age-related macular degeneration and proliferative vitreoretinopathy, are discussed. 1), an acyclic carotenoid containing 11 conjugated double bonds, is naturally present in trans-form in raw tomatoes1 and imparts red colour to the tomatoes. Dimethoxycurcumin (DMC), a more stable analogue of curcumin, can induce different epigenetic changes compared with curcumin in leukemia cells. In humans, plasma lycopene levels significantly increase following intake of tomato or tomato-based food products [31]. Unlike most vitamins (e.g., vitamin C), the bioavailability of lycopene increases upon cooking,22 partially because processing tomato-based foods releases lycopene tightly bound to vegetable fibers, allowing lycopene to be more readily available to be absorbed in the digestive tract. Lycopene is a naturally occurring chemical that gives fruits and vegetables a red color. In the same year, researchers demonstrated that chronic treatment with lycopene for four weeks significantly attenuated the cold allodynia and thermal hyperalgesia in diabetic animals (Kuhad and Chopra, 2008), emphasizing the role of antioxidants such as lycopene as an adjuvant therapy in the treatment of diabetic neuropathy. The effect of curcumin on receptor activator of NF-κB (RANK) gene expression was investigated in two human glioblastoma cells (U251 and U87). As a lipophilic antioxidant, it has been demonstrated as one of the most efficient singlet-oxygen-quenchers. Calibration graph of standard lycopene was linear in the concentration range of 200-1000 ng/mL with the detection limit of 50 ng/mL. Lycopene also inhibited TNF-α and NO release in a dose-dependent manner (Kuhad et al., 2008). Food Sources Tomatoes, tomato products, watermelon, guava, rose hips, and pink grapefruit (15) Multiple studies have shown that lycopene from thermally processed tomato products is more bioavailable than lycopene from fresh tomatoes [28]. The solid black line and 2 dotted black lines are the restricted cubic spline for the published relative risks (RRs) and 95% confidence intervals (CIs); the short dash straight line is the linear fitting curve used for linear and nonlinear analysis. Lycopene Market. Agarwal and Rao found that men who had low levels of lycopene and high levels of ROS had higher incidence of prostate cancer, hinting at a potential direct benefit of lycopene at preventing prostate cancer in those with high oxidative stress.25. Lycopene is found within the cells of tomato and should be cooked to help release lycopene and increase bioavailability. For example, consuming salads with full-fat dressing results in higher blood carotenoid levels than eating salads with reduced fat dressing. Four products containing 300 μg, 3 mg, 5 mg, or 10 mg lycopene plus other ingredients were analyzed using a ChromaDex lycopene standard. CONCLUSION: Dietary intake of tomato lycopene is beneficial to fight against OS The bioavailability of cis-isomers in food is higher than that of all-trans isomers. G. Tang, in Encyclopedia of Human Nutrition (Third Edition), 2013. Human studies linked intakes of tomato and lycopene and serum or plasma lycopene concentrations to the subsequent development of cancers, reduction of degenerative disease, and reduced risks of cardiovascular disease. In vitro experiments support the conclusion that increased bioavailability of lycopene cis-isomers is at least partially due to increased micellarization and increased uptake by the enterocyte compared to all-trans lycopene. It is transported by the lipoproteins into the plasma for distribution to the different organs [34,35]. Lycopene is a 40-carbon acyclic carotenoid containing 11 conjugated double bonds, with a molecular mass of 536. It is freely soluble in ethyl acetate and n-hexane, partially soluble in ethanol and acetone, and insoluble in water.A solution in n-hexane shows an absorption maximum at approximately 472 nm. When healthy people ingested lycopene in the form of tomato juice, tomato sauce, and as soft-gel capsule supplement for 1 week, a significantly lower concentration of oxidized LDL was observed in these subjects compared to controls. Food processing, specially thermal processing, may improve lycopene bioavailability by breaking down cell walls, which weakens the bonding forces between lycopene and tissue matrix, thus making lycopene more accessible and enhancing the cis-isomerization.
