Abstract
BACKGROUND Cruciferous vegetable sprout has been highlighted as a promising functional material rich in bioactive compounds called isothiocyanates (ITCs) and it can be grown in very short periods in controlled indoor farms. However, because ITCs content depends on multiple factors such as cultivar, germination time and myrosinase activity, those variables need to be controlled during germination or extraction to produce functional materials enriched in ITCs. Sulforaphene (SFEN), an ITC found primarily in radishes (Raphanus sativus L.), exerts beneficial effects on obesity. However, the optimal germination and extraction conditions for radish sprout (RSP) to increase SFEN content remain unascertained, and the extract's anti-obesity effect has yet to be evaluated. RESULTS The present study found that the SFEN content was highest in purple radish sprout (PRSP) among the six cultivars investigated. Optimal SFEN content occurred after 2 days of PRSP germination (2 days PRSP). To maximize the dry matter yield, total ITCs and SFEN contents in RSP extract, we found the optimal conditions for extracting PRSP [27.5 °C, 60 min, 1:75.52 solute/solvent (w/v), no ascorbic acid] using response surface methodology. Consistent with high SFEN content, 2 days PRSP extract significantly outperformed 3 days or 4 days PRSP extract in inhibiting lipid accumulation in 3T3-L1 cells. Moreover, 2 days PRSP extract suppressed adipogenesis and lipogenesis-related protein expression. CONCLUSION Regarding the cultivar, germination time and extraction conditions, optimally produced PRSP extract contains high SFEN content and exerts anti-obesity effects. Thus, we suggest PRSP extract as a potent functional material for obesity prevention. © 2024 Society of Chemical Industry.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ulmus macrocarpa Hance (UmH) bark has been traditionally utilized for medicinal purposes. The bark extract of this plant has diverse health benefits, and its potential role in enhancing bone health is of distinct interest, particularly when considering the substantial health and economic implications of bone-related pathologies, such as osteoporosis. Despite the compelling theoretical implications of UmH bark in fortifying bone health, no definitive evidence at the in vivo level is currently available, thus highlighting the innovative and as-yet-unexplored potential of this field of study. AIM OF THE STUDY Primarily, our study aims to conduct a meticulous analysis of the disparity in the concentration of active compounds in the UmH root bark (Umrb) and trunk bark (Umtb) extracts and confirm UmH bark's efficacy in enhancing bone health in vivo, illuminating the cellular mechanisms involved. MATERIALS AND METHODS The Umrb and Umtb extracts were subjected to component analysis using high-performance liquid chromatography and then assessed for their inhibitory effects on osteoclast differentiation through the TRAP assay. An ovariectomized (OVX) mouse model replicates postmenopausal conditions commonly associated with osteoporosis. Micro-CT was used to analyze bone structure parameters, and enzyme-linked immunosorbent assay and staining were used to assess bone formation markers and osteoclast activity. Furthermore, this study investigated the impact of the extract on the expression of pivotal proteins and genes involved in bone formation and resorption using mouse bone marrow-derived macrophages (BMMs). RESULTS The findings of our study reveal a significant discrepancy in the concentration of active constituents between Umrb and Umtb, establishing Umtb as a superior source for promoting bone health. I addition, a standardized pilot-scale procedure was conducted for credibility. The bone health benefits of Umtb were verified using an OVX model. This validation involved the assessment of various parameters, including BMD, BV/TV, and BS/TV, using micro-CT imaging. Additionally, the activation of osteoblasts was evaluated by Umtb by measuring specific factors such as ALP, OCN, OPG in blood samples and through IHC staining. In the same investigations, diminished levels of osteoclast differentiation factors, such as TRAP, NFATc1, were also observed. The observed patterns exhibited consistency in vitro BMM investigations. CONCLUSIONS Through verification at both in vitro levels using BMMs and in vivo levels using the OVX-induced mouse model, our research demonstrates that Umtb is a more effective means of improving bone health in comparison to Umrb. These findings pave the way for developing health-functional foods or botanical drugs targeting osteoporosis and other bone-related disorders and enhance the prospects for future research extensions, including clinical studies, in extract applications.

Abstract
Sulforaphene (SFEN), an isothiocyanate (ITC) abundant in radish (Raphanus sativus) seeds (RS), has many health benefits, including anti-obesity effects. SFEN content is affected by multiple factors during processing, such as glucoraphenin (GLE) (the precursor of SFEN) availability, myrosinase (essential for conversion from GLE to SFEN) activity, and SFEN stability. We examined the physiochemical-properties and anti-adipogenic effects of SFEN-enriched RSE produced by two processes, roasting and micro-grinding. The roasting process lowered SFEN content and myrosinase activity over 50 °C. However, among micro-grinding conditions, smaller particle size (#2 grind, ≈11.31 μm) more effectively increased SFEN content in RS compared to larger particles (#1 grind, ≈ 179.50 μm) by accelerating available GLE and myrosinase release from RS. Grind #2 also effectively inhibited the adipogenesis of 3T3-L1 pre-adipocytes compared to #1. Thus, micro-grinding can be suggested for producing SFEN-enriched RSE with anti-adipogenic activity as a functional material for obesity prevention or treatment.

Abstract
SCOPE Histone deacetylases (HDACs) play a crucial role in the transcriptional regulation of various genes which can contribute to metabolic disorders. Although sulforaphane (SFN), a natural HDAC inhibitor, has been reported to alleviate obesity in humans and mice, the specific mechanisms and how HDACs contribute to SFN's anti-obesity effects remain unclear. METHODS AND RESULTS Oral administration of SFN in mice fed high-fat diet increases peroxisome proliferator activating receptor γ coactivator (PGC1α)-induced mitochondrial biogenesis in skeletal muscle. Among HDACs, SFN specifically inhibits HDAC8 activity. SFN enhances mitochondrial DNA and adenosine triphosphate (ATP) production in C2C12 myotubes, similar to the action of PCI34051, a synthetic HDAC8-specific inhibitor. These effects are mediated by increased expression of PGC1α via upregulation of cAMP response element binding (CREB, Ser133 ) phosphorylation and p53 (Lys379 ) acetylation. These SFN-induced effects are not observed in cells with a genetic deletion of HDAC8, suggesting the existence of a regulatory loop between HDAC8 and PGC1α in SFN's action. CONCLUSION SFN prevents obesity-related metabolic dysregulation by enhancing mitochondrial biogenesis and function via targeting the HDAC8-PGCα axis. These results suggest SFN as a beneficial anti-obesity agent providing new insight into the role of HDAC8 in the PGC1α-mediated mitochondrial biogenesis, which may be a novel and promising drug target for metabolic diseases.

Abstract
Platycosides, major components of Platycodon grandiflorum (PG) extract, have been implicated in a wide range of biological effects. In particular, platycodin D (PD) is a well-known main bioactive compound of Platycosides. Despite the biological significance of PD, optimization of extract condition for PD from PG root has not been well investigated. Here, we established the optimum extraction condition as ethanol concentration of 0%, temperature of 50°C, and extraction time of 11 h to obtain PD-rich P. grandiflorum extract (PGE) by using response surface methodology (RSM) with Box-Behnken design (BBD). The 5.63 mg/g of PD was extracted from the PG root in optimum condition, and this result was close to the predicted PD content. To analyze the biological activity of PGE related to mucin production, we demonstrated the inhibitory effect of PGE on PMA-induced hyperexpression of MUC5AC as well as ERK activation, a signal mediator of MUC5AC expression. Moreover, we showed that PGE had expectorant activity in mice. These results indicated that PGE had sufficient functions as a potential mucoregulator and expectorant for treating diverse airway diseases. Additionally, we confirmed that PGE had antioxidant activity and inhibited LPS-induced proinflammatory cytokines, TNF-α, and IL-6. Taken together, PGE derived from novel optimizing conditions showed various biological effects, suggesting that PGE could be directly applied to the food industry as food material having therapeutic and preventive potential for human airway diseases.

Abstract
The effect of nanoemulsions on the stability and bioavailability of sulforaphene (SFEN) in radish seed extract (RSE) was investigated. Four types of oil were used as lipid ingredients of the nanoemulsions: soybean, high oleic acid sunflower, coconut, and hydrogenated palm oils. SFEN in RSE nanoemulsions showed greater stability to temperature, acid, and alkaline conditions than SFEN in RSE suspended in water (RSE-S). Particularly under alkaline conditions, the half-life of SFEN in the nanoemulsion with high oleic sunflower oil (RSE-HOSO) was 8 times longer than that of RSE-S. Furthermore, in the pharmacokinetics study, it was observed that AUC0-8 increased and oral clearance (CL/F) decreased significantly in rats orally administered RSE-HOSO compared with RSE-S (p < 0.05). This study indicates that the type of oil used in nanoemulsions affects the stability and bioavailability of SFEN in RSE. These results may provide a guideline for the development of functional foods containing RSE.

Abstract
Ulmus macrocarpa Hance bark (UmHb) has been used as a traditional herbal medicine in East Asia for bone concern diseases for a long time. To find a suitable solvent, we, in this study, compared the efficacy of UmHb water extract and ethanol extract which can inhibit osteoclast differentiation. Compared with two ethanol extracts (70% and 100% respectively), hydrothermal extracts of UmHb more effectively inhibited receptor activators of nuclear factor κB ligand-induced osteoclast differentiation in murine bone marrow-derived macrophages. We identified for the first time that (2R,3R)-epicatechin-7-O-β-D-apiofuranoside (E7A) is a specific active compound in UmHb hydrothermal extracts through using LC/MS, HPLC, and NMR techniques. In addition, we confirmed through TRAP assay, pit assay, and PCR assay that E7A is a key compound in inhibiting osteoclast differentiation. The optimized condition to obtain E7A-rich UmHb extract was 100 mL/g, 90 °C, pH 5, and 97 min. At this condition, the content of E7A was 26.05 ± 0.96 mg/g extract. Based on TRAP assay, pit assay, PCR, and western blot, the optimized extract of E7A-rich UmHb demonstrated a greater inhibition of osteoclast differentiation compared to unoptimized. These results suggest that E7A would be a good candidate for the prevention and treatment of osteoporosis-related diseases.

Abstract
Transient receptor potential vanilloid 1 (TRPV1) protein is a Ca2+-permeable non-selective cation channel known for its pain modulation pathway. In a previous study, it was discovered that a triple-transgenic Alzheimer's disease (AD) mouse model (3xTg-AD+/+) has anti-AD effects. The expression of proteins in the brain-derived neurotrophic factor (BDNF)/cAMP response element binding protein (CREB) pathway in a 3xTg-AD/TRPV1 transgenic mice model was investigated to better understand the AD regulatory effect of TRPV1 deficiency. The results show that TRPV1 deficiency leads to CREB activation by increasing BDNF levels and promoting phosphorylation of tyrosine receptor kinase B (TrkB), extracellular signal-regulated kinase (ERK), protein kinase B (Akt), and CREB in the hippocampus. Additionally, TRPV1 deficiency-induced CREB activation increases the antiapoptotic factor B-cell lymphoma 2 (Bcl-2) gene, which consequently downregulates Bcl-2-associated X (Bax) expression and decreases cleaved caspase-3 and cleaved poly (ADP-ribose) polymerase (PARP), which leads to the prevention of hippocampal apoptosis. In conclusion, TRPV1 deficiency exhibits neuroprotective effects by preventing apoptosis through the BDNF/CREB signal transduction pathway in the hippocampus of 3xTg-AD mice.

Abstract
As a type of stress hormone, glucocorticoids (GCs) affect numerous physiological pathways by binding to the glucocorticoid receptor (GR) and regulating the transcription of various genes. However, when GCs are dysregulated, the resulting hypercortisolism may contribute to various metabolic disorders, including obesity. Thus, attempts have been made to discover potent GR antagonists that can reverse excess-GC-related metabolic diseases. Phytochemicals are a collection of valuable bioactive compounds that are known for their wide variety of chemotypes. Recently, various computational methods have been developed to obtain active phytochemicals that can modulate desired target proteins. In this study, we developed a workflow comprising two consecutive quantitative structure-activity relationship-based machine learning models to discover novel GR-antagonizing phytochemicals. These two models collectively identified 65 phytochemicals that bind to and antagonize GR. Of these, nine commercially available phytochemicals were validated for GR-antagonist and anti-obesity activities. In particular, we confirmed that demethylzeylasteral, a phytochemical of the Tripterygium wilfordii Radix, exhibits potent anti-obesity activity in vitro through GR antagonism.

Abstract
Many probiotic species have been used as a fermentation starter for manufacturing functional food materials. We have isolated Bifidobacterium animalis subsp. lactis LDTM 8102 from the feces of infants as a novel strain for fermentation. While Glycine max has been known to display various bioactivities including anti-oxidant, anti-skin aging, and anti-cancer effects, the immune-modulatory effect of Glycine max has not been reported. In the current study, we have discovered that the extract of Glycine max fermented with B. animalis subsp. lactis LDTM 8102 (GFB 8102), could exert immuno-modulatory properties. GFB 8102 treatment increased the production of immune-stimulatory cytokines in RAW264.7 macrophages without any noticeable cytotoxicity. Analysis of the molecular mechanism revealed that GFB 8102 could upregulate MAPK2K and MAPK signaling pathways including ERK, p38, and JNK. GFB 8102 also increased the proliferation rate of splenocytes isolated from mice. In an animal study, administration of GFB 8102 partially recovered cyclophosphamide-mediated reduction in thymus and spleen weight. Moreover, splenocytes from the GFB 8102-treated group exhibited increased TNF-α, IL-6, and IL-1β production. Based on these findings, GFB 8102 could be a promising functional food material for enhancing immune function.

Abstract
Background Due to their diverse bioactivity, natural product (NP)s have been developed as commercial products in the pharmaceutical, food and cosmetic sectors as natural compound (NC)s and in the form of extracts. Following administration, NCs typically interact with multiple target proteins to elicit their effects. Various machine learning models have been developed to predict multi-target modulating NCs with desired physiological effects. However, due to deficiencies with existing chemical-protein interaction datasets, which are mostly single-labeled and limited, the existing models struggle to predict new chemical-protein interactions. New techniques are needed to overcome these limitations. Results We propose a novel NC discovery model called OptNCMiner that offers various advantages. The model is trained via end-to-end learning with a feature extraction step implemented, and it predicts multi-target modulating NCs through multi-label learning. In addition, it offers a few-shot learning approach to predict NC-protein interactions using a small training dataset. OptNCMiner achieved better prediction performance in terms of recall than conventional classification models. It was tested for the prediction of NC-protein interactions using small datasets and for a use case scenario to identify multi-target modulating NCs for type 2 diabetes mellitus complications. Conclusions OptNCMiner identifies NCs that modulate multiple target proteins, which facilitates the discovery and the understanding of biological activity of novel NCs with desirable health benefits.

Abstract
BACKGROUND Piceatannol is a resveratrol metabolite commonly found in red wine, grapes. Several studies have investigated the immune-modulating effects of piceatannol on processes related to allergic reactions. However, the relationship between piceatannol and atopic dermatitis (AD) has not yet been reported. This study sought to investigate the effects of piceatannol in animal and cell line models. METHODS AD-like symptoms and skin lesions were triggered by repeated topical treatment of Dermatophagoides farinae extract (DFE) on the skin of NC/Nga mice. The molecular mechanism of piceatannol was studied in the TNFα/IFNγ-induced HaCaT cell line. RESULTS Piceatannol attenuated DFE-induced AD-like symptoms, as shown by skin thickness, dermatitis score, scratching time, and skin water loss. Histopathological analysis showed that piceatannol suppressed DFE-induced immune cell infiltration into the skin. These results occurred concomitantly with the downregulation of inflammatory markers, including serum and skin TARC and MDC. Piceatannol decreased phosphorylation of JAK-STAT protein in the TNFα/IFNγ-induced HaCaT cell line. A molecular docking study showed that piceatannol strongly interacts with JAK1, suggesting a possible mode of action. CONCLUSION The study results showed that piceatannol, a metabolite of resveratrol, attenuates atopic dermatitis and provide important implication of development of piceatannol as functional ingredients or therapeutic agents.

Abstract
Orobol, a metabolite of genistein, is rare in natural soybean. Several studies have revealed the immune-controlling effects of orobol on inflammatory diseases. Furthermore, a few studies have demonstrated that orobol decreases pro-inflammatory compounds resulting in the alleviation of allergic reactions. However, the relationship between orobol and atopic dermatitis (AD) in animal models has not been revealed. Therefore, we sought to investigate the effects of orobol on AD-like symptoms. AD-like symptoms and skin lesions were induced by repeated topical application of Dermatophagoides farinae extract (DFE) on the skin of NC/Nga mice. Topical application of orobol attenuated DFE-induced AD-like symptoms and transepidermal water loss and increased skin hydration. Histopathological analysis revealed that orobol alleviated DFE-induced eosinophil and mast cell infiltration into the skin. These observations occurred concomitantly with the downregulation of inflammatory markers including serum TARC, MDC, and IgE. In addition, orobol alleviated dorsal Th2 cytokines such as IL-4 and IL-13. Pre-treatment of orobol decreased the activity of the MAPKs and NF-κB signalling cascade in the TNFα/IFNγ-induced HaCaT cell line. These results suggest that orobol, a natural dietary isoflavone, has therapeutic efficacy for the prevention and treatment of AD.

Abstract
The aim of this study was to isolate and identify chemical components with osteoclast differentiation inhibitory activity from Ulmus macrocarpa Hance bark. Spectroscopic analyses, including nuclear magnetic resonance (NMR) and electronic circular dichroism (ECD), resulted in the unequivocal elucidation of active compounds such as (2S)-naringenin-6-C-β-d-glucopyranoside (1), (2R)-naringenin-6-C-β-d-glucopyranoside (2), (2R,3S)-catechin-7-O-β-d-xylopyranoside (3), (2R,3S)-catechin-7-O-β-d-apiofuranoside (6), (2R,3R)-taxifolin-6-C-β-d-glucopyranoside (7), and (2S,3S)-taxifolin-6-C-β-d-glucopyranoside (8). Mechanistically, the compounds may exhibit osteoclast differentiation inhibitory activity via the downregulation of NFATc1, a master regulator involved in osteoclast formation. This is the first report of their inhibitory activities on the receptor activator of nuclear factor κB ligand (RANKL)-induced osteoclast differentiation in murine bone marrow-derived macrophages. These findings provide further scientific evidence for the rational application of the genus Ulmus for the amelioration or treatment of osteopenic diseases.

Abstract
Background Short-term hydroponic-cultured ginseng (sHCG), which is 1-year-old ginseng seedlings cultivated for 4 weeks in a hydroponic system, is a functional food item with several biological effects. However, the optimal extraction conditions for sHCG, and the bioactivity of its extracts, have not been evaluated. Methods Chlorogenic acid (CGA) and ginsenoside contents were evaluated in sHCG, white ginseng (WG), and red ginseng (RG) using high-performance liquid chromatography. Response surface methodology (RSM) was used to optimize the extraction conditions (temperature and ethanol concentration) to maximize the yield of dry matter, CGA, and four ginsenosides (Re, Rg1, Rb1, and Rd) from sHCG. The optimal extraction conditions were applied to pilot-scale production of sHCG extracts. The expression levels of tumor necrosis factor (TNF)-α/interferon (IFN)-γ-induced thymic and activation-regulated chemokines (TARC/CCL17) were measured after treatment with sHCG, WG, and RG extracts, and the effects of their bioactive compounds (CGA and four ginsenosides) on human skin keratinocytes (HaCaTs) were evaluated. Results CGA and four ginsenosides, which are bioactive compounds of sHCG, significantly inhibited TNF-α/IFN-γ-induced TARC/CCL17 expression. The optimal sHCG extraction conditions predicted by the RSM models were 80 °C and 60% ethanol (v/v). The sHCG extracts produced at the pilot scale under optimal conditions greatly alleviated TNF-α/IFN-γ-induced TARC/CCL17 production compared with WG and RG extracts. Conclusions Pesticide-free sHCG extracts, which contain high levels of CGA and the ginsenosides Re, Rg1, Rb1, and Rd as bioactive compounds, may have therapeutic potential for atopic diseases.

Abstract
The transient receptor potential vanilloid 1 (TRPV1) protein is a pain receptor that elicits a hot sensation when an organism eats the capsaicin of red chili peppers. This calcium (Ca2+)-permeable cation channel is mostly expressed in the peripheral nervous system sensory neurons but also in the central nervous system (e.g. hippocampus and cortex). Preclinical studies found that TRPV1 mediates behaviors associated with anxiety and depression. Loss of TRPV1 functionality increases expression of genes related to synaptic plasticity and neurogenesis. Thus, we hypothesized that TRPV1 deficiency may modulate Alzheimer's disease (AD). We generated a triple-transgenic AD mouse model (3xTg-AD+/+) with wild-type (TRPV1+/+), hetero (TRPV1+/-) and knockout (TRPV1-/-) TRPV1 to investigate the role of TRPV1 in AD pathogenesis. We analyzed the animals' memory function, hippocampal Ca2+ levels and amyloid-β (Aβ) and tau pathologies when they were 12 months old. We found that compared with 3xTg-AD-/-/TRPV1+/+ mice, 3xTg-AD+/+/TRPV1+/+ mice had memory impairment and increased levels of hippocampal Ca2+, Aβ and total and phosphorylated tau. However, 3xTg-AD+/+/TRPV1-/- mice had better memory function and lower levels of hippocampal Ca2+, Aβ, tau and p-tau, compared with 3xTg-AD+/+/TRPV1+/+ mice. Examination of 3xTg-AD-derived primary neuronal cultures revealed that the intracellular Ca2+ chelator BAPTA/AM and the TRPV1 antagonist capsazepine decreased the production of Aβ, tau and p-tau. Taken together, these results suggested that TRPV1 deficiency had anti-AD effects and promoted resilience to memory loss. These findings suggest that drugs or food components that modulate TRPV1 could be exploited as therapeutics to prevent or treat AD.

Abstract
Acne is a chronic skin disease that typically occurs in the teens and twenties, and its symptoms vary according to age, sex, diet, and lifestyle. The condition is characterized by hyperproliferation of keratinocytes in the epidermis, sebum overproduction, excessive growth of Propionibacterium acnes, and P. acnes-induced skin inflammation. Interleukin (IL)-1α and IL-6 are predominant in the inflammatory lesions of acne vulgaris. These cytokines induce an inflammatory reaction in the skin in the presence of pathogens or stresses. Moreover, IL-1α accelerates the production of keratin 16, which is typically expressed in wounded or aberrant skin, leading to abnormalities in architecture and hyperkeratinization. Orobol (3',4',5,7-tetrahydroxyisoflavone) is a metabolite of genistein that inhibited the P. acnes-induced increases in IL-6 and IL-1α levels in human keratinocytes (HaCaTs) more effectively compared with salicylic acid. In addition, orobol decreased the IL-1α and IL-6 mRNA levels and inhibited the phosphorylation of inhibitor of kappa-B kinase, nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, alpha, and mitogen-activated protein kinase induced by P. acnes. Finally, the expression of Ki67 was decreased by orobol. Thus, orobol ameliorated the inflammation and hyperkeratinization induced by heat-killed P. acnes and thus has potential for use in functional foods and cosmetics.

Abstract
Atopic dermatitis is a skin disease characterized by chronic inflammatory lesions, and new therapies are needed to address its rising prevalence. Soy isoflavone has been highlighted as a potential new cosmeceutical material that may have applications in atopic dermatitis care. We have developed a technique to attach an additional -OH group to the ortho position of -OH in the phenol ring using a special enzyme. By adding the -OH group to daidzein, 7,3',4'-trihydroxyisoflavone can be generated for possible use as a cosmeceutical and functional food material. In this study, we sought to examine the anti-atopic effects of 7,3',4'-trihydroxyisoflavone, an analog of daidzein. Topical application of 7,3',4'-trihydroxyisoflavone reduced Dermatophagoides farina extract-induced atopic dermatitis symptoms in NC/Nga mice. Histological analysis demonstrated that 7,3',4'-trihydroxyisoflavone suppressed D. farina extract-induced infiltration of eosinophils and mast cells into skin lesions. We also found that 7,3',4'-trihydroxyisoflavone significantly reduces the D. farina extract-induced increases in serum IgE and macrophage-derived chemokine (CCL22) levels. We observed that 7,3',4'-trihydroxyisoflavone suppresses atopic markers including macrophage-derived chemokine (CCL22) and thymus and activation-regulated chemokine (CCL17) in HaCaT cells. 7,3',4'-Trihydroxyisoflavone also reduced TNF-α/IFN-γ-induced phosphorylation of ERK1/2 and JNK1/2. These results highlight several desirable properties of 7,3',4'-trihydroxyisoflavone, which support its use as a cosmeceutical ingredient for the treatment of atopic dermatitis.

Abstract
Cacao (Theobroma cacao) has a significant polyphenol content and has been reported to elicit anti-obesity effects. Previous studies have focused on the properties of cacao extract and procyanidins, while the potential mechanisms have not been fully elucidated. Here, we investigated the inhibitory effects of procyanidin metabolites on adipogenic cocktail-induced adipogenesis and lipogenesis in 3T3-L1 preadipocytes. It was observed that 5-(3',4'-dihydroxyphenyl)-γ-valerolactone (DHPV), a major procyanidin metabolite, exhibited the greatest inhibitory effects on adipogenesis and lipogenesis. DHPV dose-dependently reduced the expression levels of proteins involved in adipogenesis including peroxisome proliferator-activated receptor γ (PPAR γ) and CCAT/enhancer-binding protein α (C/EBP α), as well as lipogenesis-related factors such as fatty acid synthase and acetyl-CoA carboxylase. These inhibitory effects were primarily due to G1 phase arrest and the suppression of cell proliferation during mitotic clonal expansion, the early stage of adipogenesis. In an extensive kinase array, DHPV directly suppressed activation of the CDK2/cyclin O complex, and inhibited the phosphorylation of C/EBP β, which is responsible for the induction of PPAR γ and C/EBP α. Taken together, these findings suggest that DHPV is a highly biologically active compound with potential anti-obesity effects and works by inhibiting the intracellular lipid content and cell differentiation.

Abstract
Identification of novel probiotic strains is of great interest in the field of functional foods. Specific strains of heat-killed bacteria have been reported to exert immunomodulatory effects. Herein, we investigated the immune-stimulatory function of heat-killed Lactobacillus plantarum KCTC 13314BP (LBP). Treatment with LBP significantly increased the production of TNF-α and IL-6 by macrophages. More importantly, LBP was able to enhance the phagocytic activity of macrophages against bacterial particles. Activation of p38, JNK, ERK, NF-κB, and STAT3 was involved in the immunomodulatory function of LBP. LBP treatment significantly increased production of TNF-α by bone marrow-derived macrophages and splenocytes, further confirming the immunostimulatory effect of LBP in primary immune cells. Interestingly, the immunomodulatory effects of LBP were much stronger than those of Lactobacillus rhamnosus GG, a well-known probiotic strain. These results indicate that LBP can be a promising immune-enhancing functional food agent.

Abstract
Yak-Kong (YK), a small black soybean (Glycine max) in Korea, contained higher concentrations of antioxidants than ordinary black soybean or yellow soybean in our previous study. We prepared the fermented YK extract by using a novel lactic acid bacterium, Pediococcus pentosaceus AOA2017 (AOA2017) isolated from Eleusine coracana, and found that the antioxidant ability was enhanced after fermentation. In order to investigate the cause of the enhanced antioxidant ability in the fermented YK extract, we conducted a phenolic composition analysis. The results show that proanthocyanidin decreased and phenolic acids increased with a statistical significance after fermentation. Among the phenolic acids, p-coumaric acid was newly produced at about 11.7 mg/100 g, which did not exist before the fermentation. Further, the fermented YK extract with increased p-coumaric acid significantly inhibited the lipopolysaccharide-induced THP-1 monocyte-endothelial cell adhesion compared to the unfermented YK extract. The fermented YK extract also suppressed the protein expression levels of vascular cell adhesion molecule (VCAM)-1 in human umbilical vein endothelial cells (HUVECs). Together with the previous studies, our results suggest that the extract of YK fermented by AOA2017 has potential to be a new functional food material with its enhanced bioactive compounds which may help to prevent atherosclerosis caused by oxidative stress.

Abstract
SCOPE Sulforaphane is an herbal isothiocyanate enriched in cruciferous vegetables. Here, the authors investigate whether sulforaphane modulates the production of amyloid-β (Aβ) and tau, the two main pathological factors in Alzheimer's disease (AD). METHODS AND RESULTS A triple transgenic mouse model of AD (3 × Tg-AD) is used to study the effect of sulforaphane. Oral gavage of sulforaphane reduces protein levels of monomeric and polymeric forms of Aβ as well as tau and phosphorylated tau in 3 × Tg-AD mice. However, sulforaphane treatment do not affect mRNA expression of amyloid precursor protein or tau. As previous studies show that Aβ and tau metabolism are influenced by a heat shock protein (HSP) co-chaperone, C-terminus of HSP70-interacting protein (CHIP), the authors examine whether sulforaphane can modulate CHIP. The authors find that sulforaphane treatment increase levels of CHIP and HSP70. Furthermore, observations of CHIP-deficient primary neurons derived from 3 × Tg-AD mice suggest that sulforaphane treatment increase CHIP level and clear the accumulation of Aβ and tau. Finally, sulforaphane ameliorated memory deficits in 3 × Tg-AD mice as reveal by novel object/location recognition tests and contextual fear conditioning tests. CONCLUSION These results demonstrate that sulforaphane treatment upregulates CHIP and has the potential to decrease the accumulation of Aβ and tau in patients with AD.

Abstract
Previously, we reported that high-fat-diet (HFD)-induced obesity stimulates melanoma progression in the B16F10 allograft model. In this study, we examined whether oleuropein (OL), the most abundant phenolic compound in olives, inhibits HFD-induced melanoma progression. Four-week-old male C57BL/6N mice were fed a HFD-diet with or without OL. After 16 weeks of feeding, B16F10-luc cells were subcutaneously injected and the primary tumor was resected 3 weeks later. OL suppressed HFD-induced solid tumor growth. In the tumor tissues, OL reduced HFD-induced expression of angiogenesis (CD31, VE-cadherin, VEGF-A, and VEGFR2), lymphangiogenesis (LYVE-1, VEGF-C, VEGF-D, and VEGFR3), and hypoxia (HIF-1α and GLUT-1) markers as well as HFD-induced increases in lipid vacuoles and M2 macrophages (MΦs). All animals were euthanized 2.5 weeks after tumor resection. OL suppressed HFD-induced increases in lymph node (LN) metastasis; expression of VEGF-A, VEGF-C, and VEGF-D in the LN; and M2-MΦs and the size of adipocytes in adipose tissues surrounding LNs. Co-culture results revealed that the crosstalk between B16F10s, M2-MΦs, and differentiated 3T3-L1 cells under hypoxic conditions increased the secretion of VEGF-A and -D, which stimulated tube formation and migration of endothelial cells (HUVECs) and lymphatic endothelial cells (LEC), respectively. Additionally, OL directly inhibited the differentiation of 3T3-L1 preadipocytes and tube formation by HUVECs and LECs. The overall results indicated that dietary OL inhibits lipid and M2-MΦ accumulation in HFD-fed mice, which contributes to decreases in VEGF secretion, thereby leading to inhibition of angiogenesis and lymphangiogenesis.

Abstract
Among many functional foods and their phytochemicals, ingestion of soybean (Glycine max) is highly correlated to reduced risk of cardiovascular diseases. Validation of potential health benefits of functional foods requires information about the bioavailability and metabolism of bioactive compounds. In this context, several phase I and II metabolites of isoflavones were target-analyzed in the plasma of rats acutely supplemented with soybean embryo extract. A daidzein metabolite, 7,8,4'-trihydroxyisoflavone (7,8,4'-THI), was found to have the highest average area under curve value (574.3±112.8). Therefore, its potential prevention effect on atherosclerosis was investigated using monocyte-endothelial cell adhesion assay. Different from its precursor daidzein or daidzin, 7,8,4'-THI attenuated adhesion of THP-1 monocytes to tumor necrosis factor-alpha (TNF-α) stimulated human umbilical vein endothelial cells (HUVECs). In addition, 7,8,4'-THI significantly downregulated TNF-α stimulated the expression of vascular cell adhesion molecule-1 and monocyte chemotactic protein-1 and phosphorylation of IκB kinase and IκBα involved in the initiation of atherosclerosis in HUVECs. Therefore, 7,8,4'-THI, a highly bioavailable hydroxylated isoflavone metabolite, has potential anti-atherosclerotic effect via inhibiting monocyte-endothelial adhesion.

Abstract
Yak-Kong (YK) (Glycine max), a small black soybean cultivar with a green embryo, was evaluated for functional constituents with a focus on atherosclerosis prevention. In comparison to common yellow and black soybean cultivars, YK contains significantly higher concentrations of antioxidants, particularly in its seed coat. A comprehensive phenolic composition analysis revealed that proanthocyanidins were the major phenolic group in YK. In contrast to other proanthocyanidin-rich foods, YK was rich in bioavailable proanthocyanidins (with a degree of polymerization ≤3) specifically with A-type dimers. Significant concentrations of phloridzin and coumestrol were also exclusively found in YK seed coat and the embryo, respectively. Extracts of both the proanthocyanidin-rich seed coat and isoflavonoid-rich embryo of YK attenuated adhesion of THP-1 to LPS-stimulated human umbilical vascular endothelial cells, suggesting that they are important sources of coronary heart disease-preventive phenolics. YK has promising potential for further development as a functional food source targeted at atherosclerosis prevention.

Abstract
During the early stages of atherosclerosis, monocytes bind and migrate into the endothelial layer, promoting inflammation within the aorta. In order to prevent the development of atherosclerosis, it is critical to inhibit such inflammation. The therapeutic effects of ginger have been investigated in several models of cardiovascular disease. However, although a number of previous studies have focused on specific compounds, the mechanisms of action responsible remain unclear. Here, we investigated five major compounds present in ginger, and observed that gingerenone A exhibited the strongest inhibitory effects against tumor necrosis factor (TNF)-α and lipopolysaccharide (LPS) induced monocyte-endothelial adhesion. Furthermore, gingerenone A significantly suppressed the expression of TNF-α and LPS-induced vascular cell adhesion molecule-1 (VCAM-1) and chemokine (C-C motif) ligand 2 (CCL2), key mediators of the interaction between monocytes, and endothelial cells. Transactivation of nuclear factor-κB (NF-κB), which is a key transcription factor of VCAM-1 and CCL2, was induced by TNF-α and LPS, and inhibited by treatment of gingerenone A. Gingerenone A also inhibited the phosphorylation of NF-κB inhibitor (IκB) α and IκB Kinase. Taken together, these results demonstrate that gingerenone A attenuates TNF-α and LPS-induced monocyte adhesion and the expression of adhesion factors in endothelial cells via the suppression of NF-κB signaling.

Abstract
SCOPE Ginger exerts protective effects on obesity and its complications. Our objectives here are to identify bioactive compounds that inhibit adipogenesis and lipid accumulation in vitro, elucidate the anti-obesity effect of gingerenone A (GA) in diet-induced obesity (DIO), and investigate whether GA affects adipose tissue inflammation (ATI). METHODS AND RESULTS Oil red O staining showed that GA had the most potent inhibitory effect on adipogenesis and lipid accumulation in 3T3-L1 cells among ginger components tested at a single concentration (40 μM). Consistent with in vitro data, GA attenuates DIO by reducing fat mass in mice. This was accompanied by a modulation of fatty acid metabolism via activation of AMP-activated protein kinase (AMPK) in vitro and in vivo. Additionally, GA suppressed ATI by inhibiting macrophage recruitment and downregulating pro-inflammatory cytokines. CONCLUSION These results suggest that GA may be used as a potential therapeutic candidate for the treatment of obesity and its complications by suppressing adipose expansion and inflammation.

Abstract
Ginsenosides are major pharmacologically active compounds present in ginseng (Panax ginseng). Among the ginsenosides, 20-O-β-D-glucopyranosyl-20(S)-protopanaxadiol (GPPD) and ginsenoside Rb1 (Rb1) have previously been reported to exhibit anti-wrinkle effects. In this study, 20(S)-protopanaxadiol (20(S)-PPD), an aglycone derivative of the Rb1 metabolite was investigated for its anti-wrinkle benefit and compared to GPPD and Rb1. The anti-wrinkle effect of 20(S)-PPD during solar UV light was investigated using a human skin equivalent model and human keratinocytes. 20(S)-PPD attenuated solar UV-induced matrix metalloproteinase (MMP)-1 expression to a greater extent than GPPD and Rb1. 20(S)-PPD treatment modulated MMP-1 mRNA expression and the transcriptional activity of activator protein (AP)-1, a major transcription factor of MMP-1. Two upstream signaling pathways for AP-1, the MEK1/2-ERK1/2-p90RSK and MEK3/6-p38 pathways, were also suppressed. Taken together, these findings highlight the potential of 20(S)-PPD for further development as a preventative agent for sunlight-induced skin wrinkle. J. Cell.

Abstract
Obesity-induced inflammation causes skeletal muscle atrophy accompanied by disruption of oxidative metabolism and is implicated in metabolic complications such as insulin resistance and type 2 diabetes. We previously reported that 4-1BB, a member of the tumor necrosis factor receptor superfamily, participated in obesity-induced skeletal muscle inflammation. Here, we show that the absence of 4-1BB in obese mice fed a high-fat diet led to a decrease in expression of atrophic factors (MuRF1 and Atrogin-1) with suppression of NF-κB activity, and that this was accompanied by increases in mitochondrial oxidative metabolic genes/proteins (e.g., PGC-1α, CPT1β, etc.) expression and oxidative muscle fibers marker genes/proteins in the skeletal muscle. These findings suggest that 4-1BB-mediated inflammatory signaling could be a potential target for combating obesity-related muscle atrophy and metabolic derangement in skeletal muscle.

Abstract
Soybean-derived isoflavones have been investigated for their preventative effects against UV-induced symptoms of skin damage including wrinkle formation and inflammation. Haematococcus pluvialis is a freshwater species of Chlorophyta that contains high concentrations of the natural carotenoid pigment astaxanthin. Astaxanthin is known to be involved in retinoic acid receptor (RAR) signaling and previously been associated with the inhibition of activator protein (AP)-1 dependent transcription. Based on previous studies, we hypothesized that a combination of soy extract (SE) and Haematococcus extract (HE) may prevent UVB-induced photoaging through specific signaling pathways, as measured by UVB-induced wrinkling on hairless mice skin and expression changes in human dermal fibroblasts (HDFs). The 1:2 ratio of SE and HE mixture (SHM) showed the optimal benefit in vivo. SHM was found to inhibit wrinkle formation via the downregulation of matrix metalloproteinase (MMP)-1 mRNA and protein expression. SHM also inhibited mitogen-activated protein kinase (MAPK) phosphorylation and the transactivation of AP-1 which plays an important role in regulating MMP expression. These results highlight the potential for SHM to be developed as a therapeutic agent to prevent UVB-induced skin wrinkling.

Abstract
SCOPE Brain-derived neurotrophic factor (BDNF) is a neurotrophin that supports the survival of existing neurons and encourages the growth and differentiation of new neurons and synapses. We investigated the effect of sulforaphane, a hydrolysis product of glucoraphanin present in Brassica vegetables, on neuronal BDNF expression and its synaptic signaling pathways. METHODS AND RESULTS Mouse primary cortical neurons and a triple-transgenic mouse model of Alzheimer's disease (3 × Tg-AD) were used to study the effect of sulforaphane. Sulforaphane enhanced neuronal BDNF expression and increased levels of neuronal and synaptic molecules such as MAP2, synaptophysin, and PSD-95 in primary cortical neurons and 3 × Tg-AD mice. Sulforaphane elevated levels of synaptic TrkB signaling pathway components, including CREB, CaMKII, ERK, and Akt in both primary cortical neurons and 3 × Tg-AD mice. Sulforaphane increased global acetylation of histone 3 (H3) and H4, inhibited HDAC activity, and decreased the level of HDAC2 in primary cortical neurons. Chromatin immunoprecipitation analysis revealed that sulforaphane increased acetylated H3 and H4 at BDNF promoters, suggesting that sulforaphane regulates BDNF expression via HDAC inhibition. CONCLUSION These findings suggest that sulforaphane has the potential to prevent neuronal disorders such as Alzheimer's disease by epigenetically enhancing neuronal BDNF expression and its TrkB signaling pathways.

Abstract
Nutrient deprivation strategies have been proposed as an adjuvant therapy for cancer cells due to their increased metabolic demand. We examined the specific inhibitory effects of amino acid deprivation on the metastatic phenotypes of the human triple-negative breast cancer (TNBC) cell lines MDA-MB-231 and Hs 578T, as well as the orthotopic 4T1 mouse TNBC tumor model. Among the 10 essential amino acids tested, methionine deprivation elicited the strongest inhibitory effects on the migration and invasion of these cancer cells. Methionine deprivation reduced the phosphorylation of focal adhesion kinase, as well as the activity and mRNA expression of matrix metalloproteinases MMP-2 and MMP-9, two major markers of metastasis, while increasing the mRNA expression of tissue inhibitor of metalloproteinase 1 in MDA-MB-231 cells. Furthermore, methionine restriction downregulated the metastasis-related factor urokinase plasminogen activatior and upregulated plasminogen activator inhibitor 1 mRNA expression. Animals on the methionine-deprived diet showed lower lung metastasis rates compared to mice on the control diet. Taken together, these results suggest that methionine restriction could provide a potential nutritional strategy for more effective cancer therapy.

Abstract
Licorice extracts containing glycyrrhizin exhibit anti-carcinogenic properties. Because glycyrrhizin induces severe hypokalemia and hypertension, we prepared a hexane/ethanol extract of Glycyrrhizauralensis (HEGU) that lacks glycyrrhizin, and showed that HEGU induces apoptosis and G1 cell cycle arrest and inhibits migration of DU145 human prostate cancer cells. Our previous in vitro studies identified two active components in HEGU: isoangustone A, which induces apoptosis and G1 cycle arrest, and licoricidin, which inhibits metastasis. This study examined whether HEGU and licoricidin inhibit metastasis using the 4T1 mammary cancer model. Both HEGU and licoricidin treatment reduced pulmonary metastasis and the expression of CD45, CD31, HIF-1α, iNOS, COX-2, and VEGF-A in tumor tissues. Additionally, a decrease in protein expression of VEGF-R2, VEGF-C, VEGF-R3, and LYVE-1 was noted in tumor tissues of licoricidin-treated mice. Furthermore, the blood concentrations of MMP-9, ICAM-1, VCAM-1, and VEGF-A were decreased in HEGU-treated mice. In vitro 4T1 cell culture results showed that both HEGU and licoricidin inhibited cell migration, MMP-9 secretion, and VCAM expression. The present study demonstrates that the licoricidin in HEGU inhibits lung metastasis of 4T1 mammary carcinoma cells, which may be mediated via inhibition of cancer cell migration, tumor angiogenesis, and lymphangiogenesis.

Abstract
Benzyl isothiocyanate (BITC) is a hydrolysis product of glucotropaeolin, a compound found in cruciferous vegetables, and has been shown to have anti-tumor properties. In the present study, we investigated whether BITC inhibits the development of prostate cancer in the transgenic adenocarcinoma mouse prostate (TRAMP) mice. Five-week old, male TRAMP mice and their nontransgenic littermates were gavage-fed with 0, 5, or 10 mg/kg of BITC every day for 19 weeks. The weight of the genitourinary tract increased markedly in TRAMP mice and this increase was suppressed significantly by BITC feeding. H and E staining of the dorsolateral lobes of the prostate demonstrated that well-differentiated carcinoma (WDC) was a predominant feature in the TRAMP mice. The number of lobes with WDC was reduced by BITC feeding while that of lobes with prostatic intraepithelial neoplasia was increased. BITC feeding reduced the number of cells expressing Ki67 (a proliferation marker), cyclin A, cyclin D1, and cyclin-dependent kinase (CDK)2 in the prostatic tissue. In vitro cell culture results revealed that BITC decreased DNA synthesis, as well as CDK2 and CDK4 activity in TRAMP-C2 mouse prostate cancer cells. These results indicate that inhibition of cell cycle progression contributes to the inhibition of prostate cancer development in TRAMP mice treated with BITC.

Abstract
A complicated interplay between resident mast cells and other recruited inflammatory cells contributes to the development and progression of allergic inflammation entailing the promotion of T helper 2 (Th2) cytokine responses. The current study examined whether resveratrol suppressed the production of inflammatory Th2 cytokines in cultured rat basophilic leukemia RBL-2H3 cells. Cells pre-treated with resveratrol nontoxic at 1–25[Formula: see text][Formula: see text]M were sensitized with anti-dinitrophenyl (anti-DNP), and subsequently stimulated by dinitrophenyl–human serum albumin (DNP–HSA) antigen. Resveratrol dose-dependently diminished the secretion of interleukin (IL)-3, IL-4, IL-13 as well as tumor necrosis factor (TNF)-[Formula: see text] by the antigen stimulation from sensitized cells. It was found that resveratrol mitigated the phosphorylation of p38 MAPK, ERK, and JNK elevated in mast cells exposed to Fc epsilon receptor I (Fc[Formula: see text]RI)-mediated immunoglobulin E (IgE)-antigen complex. The Fc[Formula: see text]RI aggregation was highly enhanced on the surface of mast cells following the HSA stimulation, which was retarded by treatment with 1–25[Formula: see text][Formula: see text]M resveratrol. The IgE-receptor engagement rapidly induced tyrosine phosphorylation of c-Src-related focal adhesion protein paxillin involved in the cytoskeleton rearrangement. The Fc[Formula: see text]RI-mediated rapid activation of c-Src and paxillin was attenuated in a dose-dependent manner. In addition, the paxillin activation entailed p38 MAPK and ERK-responsive signaling, but the JNK activation was less involved. Consistently, oral administration of resveratrol reduced the tissue level of phosphorylated paxillin in the dorsal skin of DNP–HSA-challenged mice. The other tyrosine kinase Tyk2-STAT1 signaling was activated in the dorsal epidermis of antigen-exposed mice, which was associated with allergic inflammation. These results showed that resveratrol inhibited Th2 cytokines- and paxillin-linked allergic responses dependent upon MAPK signaling. Therefore, resveratrol may possess the therapeutic potential of targeting mast cells in preventing the development of allergic inflammation.

Abstract
BACKGROUND/OBJECTIVES Obesity is a risk factor of breast cancer in postmenopausal women. Estrogen deprivation has been suggested to cause alteration of lipid metabolism thereby creating a cellular microenvironment favoring tumor growth. The aim of this study is to investigate the effects of estrogen depletion in combination with excess energy supply on breast tumor development. MATERIALS/METHODS Ovariectomized (OVX) or sham-operated C3H/HeN mice at 4 wks were provided with either a normal diet or a high-fat diet (HD) for 16 weeks. Breast tumors were induced by administration of 7,12-dimethylbenz(a)anthracene once a week for six consecutive weeks. RESULTS Study results showed higher serum concentrations of free fatty acids and insulin in the OVX+HD group compared to other groups. The average tumor volume was significantly larger in OVX+HD animals than in other groups. Expressions of mammary tumor insulin receptor and mammalian target of rapamycin proteins as well as the ratio of pAKT/AKT were significantly increased, while pAMPK/AMPK was decreased in OVX+HD animals compared to the sham-operated groups. Higher relative expression of liver fatty acid synthase mRNA was observed in OVX+HD mice compared with other groups. CONCLUSIONS These results suggest that excess energy supply affects the accelerated mammary tumor growth in estrogen deprived mice.

Abstract
Abstract
Epidemiological studies indicate that obesity-associated metabolic stress increases the risk of developing several cancers. We previously reported that a high-fat diet (HFD)-induced obesity stimulates tumor growth and metastasis of B16F10 melanoma cancer cells in C57BL/6 mice. OL, the most abundant phenolic compound in olives, was reported to exert several physiological activities, including antioxidative, anticancer, and antimicrobial activities. In the present study, we examined whether OL inhibits HFD-induced melanoma progression in the B16F10 allograft model. Four-week old, male C57BL/6N mice were fed a diet [control diet (10 kcal% fat), HFD (60 kcal% fat), HFD + 0.02% OL, or HFD + 0.04% OL]. Twelve weeks after the initiation of feeding, fasting blood glucose, plasma insulin, and HOMA-IR were increased in HFD-fed mice, which was suppressed by dietary OL. Dual-energy X-ray absorptiometry results revealed that the proportion of lean body mass was decreased, whereas that of fat mass was increased in HFD-fed mice, and these changes were suppressed by dietary OL. After 16 weeks of feeding, B16F10-luc cells were subcutaneously injected into the animals’ left flank; bioluminescence imaging was conducted; and the primary tumor was resected 3 weeks later. OL suppressed HFD-induced solid tumor growth; HFD-induced increases in the expression of Ki67, cyclin D1, VEGF-A, VEGF-C, VEGF-D, CD31 (platelet endothelial cell adhesion molecule-1) and LYVE (lymphatic vessel endothelial receptor)-1; and HFD-induced decreases in TUNEL-positive apoptotic cells and cleaved PARP levels in the tumor tissues. OL also suppressed HFD-induced changes in the levels of many cytokines/chemokines in tumor tissues. All animals were killed 3 weeks after the tumor resection. OL suppressed HFD-induced increases in the size of LN; LN metastasis; and expression of VEGF-A and VEGF-C in the LN. OL suppresses HFD-induced increases in the size of adipocytes and accumulation of F4/80+ macrophages in adipose tissues surrounding the LN. In vitro culture results revealed that OL inhibited lipid accumulation in 3T3-L1 preadipocytes and the migration and viability of B16F10 cells. The present results demonstrated that dietary OL suppresses tumor growth and LN metastasis in HFD-fed mice. These effects are probably mediated, at least in part, via the inhibition of lipid accumulation, thereby reducing obesity-associated metabolic stress. Additionally, in vitro results indicate that OL may directly inhibit melanoma cell growth and migration, which may be one of the mechanisms by which dietary OL suppress melanoma progression in these mice.

Abstract
We examined the modulatory activity of β-caryophyllene (CA) and gene expression in colitic colon tissues in a dextran sulfate sodium (DSS)-induced colitis model. Experimental colitis was induced by exposing male BALB/c mice to 5% DSS in drinking water for 7 days. CA (30 or 300 mg/kg) was administered orally once a day together with DSS. CA administration attenuated the increases in the disease activity index, colon weight/length ratio, inflammation score, and myeloperoxidase activity in DSS-treated mice. Microarray analysis showed that CA administration regulated the expression in colon tissue of inflammation-related genes including those for cytokines and chemokines (Ccl2, Ccl7, Ccl11, Ifitm3, IL-1β, IL-28, Tnfrsf1b, Tnfrsf12a); acute-phase proteins (S100a8, Saa3, Hp); adhesion molecules (Cd14, Cd55, Cd68, Mmp3, Mmp10, Sema6b, Sema7a, Anax13); and signal regulatory proteins induced by DSS. CA significantly suppressed NF-κB activity, which mediates the expression of a different set of genes. These results suggest that CA attenuates DSS-induced colitis, possibly by modulating the expression of genes associated mainly with colon inflammation through inhibition of DSS-induced NF-κB activity.

Abstract
We reported previously that high-fat diet (HFD) feeding stimulated solid tumor growth and lymph node (LN) metastasis in C57BL/6N mice injected with B16F10 melanoma cells. β-caryophyllene (BCP) is a natural bicyclic sesquiterpene found in many essential oils and has been shown to exert anti-inflammatory activities. To examine whether BCP inhibits HFD-induced melanoma progression, 4-weeks old, male C57BL/6N mice were fed a control diet (CD, 10 kcal% fat) or HFD (60 kcal% fat + 0, 0.15 or 0.3% BCP) for the entire experimental period. After 16 weeks of feeding, B16F10s were subcutaneously injected into mice. Three weeks later, tumors were resected, and mice were killed 2 weeks post-resection. Although HFD feeding increased body weight gain, fasting blood glucose levels, solid tumor growth, LN metastasis, tumor cell proliferation, angiogenesis and lymphangiogenesis, it decreased apoptotic cells, all of which were suppressed by dietary BCP. HFD feeding increased the number of lipid vacuoles and F4/80+ macrophage (MΦ) and macrophage mannose receptor (MMR)+ M2-MΦs in tumor tissues and adipose tissues surrounding the LN, which was suppressed by BCP. HFD feeding increased the levels of CCL19 and CCL21 in the LN and the expression of CCR7 in the tumor; these changes were blocked by dietary BCP. In vitro culture results revealed that BCP inhibited lipid accumulation in 3T3-L1 preadipocytes; monocyte migration and monocyte chemoattractant protein-1 secretion by B16F10s, adipocytes and M2-MΦs; angiogenesis and lymphangiogenesis. The suppression of adipocyte and M2-cell accumulation and the inhibition of CCL19/21-CCR7 axis may be a part of mechanisms for the BCP suppression of HFD-stimulated melanoma progression.

Abstract
Berteroin (5-methylthiopentyl isothiocyanate) is a sulforaphane analog present in cruciferous vegetables, including Chinese cabbage, rucola salad leaves, and mustard oil. We examined whether berteroin exerts anti-inflammatory activities using lipopolysaccharide (LPS)-stimulated Raw 264.7 macrophages and 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced mouse skin inflammation models. Berteroin decreased LPS-induced release of inflammatory mediators and pro-inflammatory cytokines in Raw 264.7 macrophages. Berteroin inhibited LPS-induced degradation of inhibitor of κBα (IκBα) and nuclear factor-κB p65 translocation to the nucleus and DNA binding activity. Furthermore, berteroin suppressed degradation of IL-1 receptor-associated kinase and phosphorylation of transforming growth factor β activated kinase-1. Berteroin also inhibited LPS-induced phosphorylation of p38 MAPK, ERK1/2, and AKT. In the mouse ear, berteroin effectively suppressed TPA-induced edema formation and down-regulated iNOS and COX-2 expression as well as phosphorylation of AKT and ERK1/2. These results demonstrate that berteroin exhibits potent anti-inflammatory properties and suggest that berteroin can be developed as a skin anti-inflammatory agent.

Abstract
Background: A greater intake of vegetables and fruits has been linked to a reduced incidence of colon cancer. Flavonoids are polyphenolic compounds which are broadly distributed in fruits and vegetables and display a remarkable spectrum of physiological activities, including anti-carcinogenic effects. The objective of this study was to determine the mechanisms by which kaempferol, a flavonol present in tea, apples, strawberries, and beans, inhibits the growth of HT-29 human colon cancer cells. Methods: To examine the effects of kaempferol on cell cycle progression in HT-29 cells, cells were treated with various concentrations (0–60 μmol/L) of kaempferol. Cell proliferation and DNA synthesis were evaluated by MTT assay and [3H]thymidine incorporation assay, respectively. Fluorescence-activated cell sorting analyses were conducted to calculate cell cycle phase distribution. Western blot analyses and in vitro kinase assays were used to estimate the expression of proteins involved in the regulation of cell cycle progression and the activity of cyclin-dependent kinase (CDK)s, respectively. Results: Kaempferol decreased viable cell numbers and [3H]thymidine incorporation into DNA of HT-29 cells in a dose-dependent manner. Kaempferol induced G1 cell cycle arrest within 6 h and G2/M arrest at 12 h. Kaempferol inhibited the activity of CDK2 and CDK4 as well as the protein expression of CDK2, CDK4, cyclins D1, cyclin E, and cyclin A, and suppressed the phosphorylation of retinoblastoma protein. Additionally, kaempferol decreased the levels of Cdc25C, Cdc2, and cyclin B1 proteins, as well as the activity of Cdc2. Conclusions: The present results indicate that kaempferol induces G1 and G2/M cell cycle arrest by inhibiting the activity of CDK2, CDK4, and Cdc2. The induction of cell cycle arrest may be one of the mechanisms by which kaempferol exerts anti-carcinogenic effects in colon cancer cells.

Abstract
BACKGROUND Novel dietary agents for colon cancer prevention and therapy are desired. Kaempferol, a flavonol, has been reported to possess anticancer activity. However, little is known about the molecular mechanisms of the anticancer effects of kaempferol. The aim of this study was to determine the inhibitory effect of kaempferol on growth factor-induced proliferation and to elucidate its underlying mechanisms in the HT-29 human colon cancer cell line. METHODS To assess the effects of kaempferol and/or growth factors [insulin-like growth factor (IGF)-I and heregulin (HRG)-β], cells were cultured with or without 60 μmol/L kaempferol and/or 10 nmol/L IGF-I or 20 μg/L HRG-β. Cell proliferation, DNA synthesis, and apoptosis were determined by a cell viability assay, a [(3)H]thymidine incorporation assay, and Annexin-V staining, respectively. Western blotting, immunoprecipitation, and an in vitro kinase assay were conducted to evaluate expression and activation of various signaling molecules involved in the IGF-I receptor (IGF-IR) and ErbB3 signaling pathways. RESULTS IGF-I and HRG-β stimulated HT-29 cell growth but did not abrogate kaempferol-induced growth inhibition and apoptosis. Kaempferol reduced IGF-II secretion, HRG expression and phosphorylation of Akt and extracellular signal-regulated kinase (ERK)-1/2. Kaempferol reduced IGF-I- and HRG-β-induced phosphorylation of the IGF-IR and ErbB3, their association with p85, and phosphatidylinositol 3-kinase (PI3K) activity. Additionally, kaempferol inhibited IGF-I- and HRG-β-induced phosphorylation of Akt and ERK-1/2. CONCLUSIONS The results demonstrate that kaempferol downregulates activation of PI3K/Akt and ERK-1/2 pathways by inhibiting IGF-IR and ErbB3 signaling in HT-29 cells. We suggest that kaempferol could be a useful chemopreventive agent against colon cancer.

Abstract
Abstract
Carnosic acid is a natural benzenediol abietane diterpene found in rosemary and common sage and reported to exhibit anti-inflammatory, antioxidant, and anticarcinogenic activities. The present study examined the effects of carnosic acid on the metastatic characteristics of B16F10 cells. Results from transwell migration assays revealed that carnosic acid inhibited B16F10 migration in a dose-dependent manner. Western blot analysis of cell conditioned media showed that carnosic acid significantly suppressed the secretion of MMP-9, TIMP-1, uPA, and VCAM-1. However, the secretion of TIMP-2 was significantly increased in cells treated with 10 μmol/L of carnosic acid. Moreover, carnosic acid suppressed the expression of mesenchymal markers such as snail, Slug, vimentin, and N-cadherine and increased that of E-cadherin, an epithelial marker. We previously noted that chronic consumption of a high-fat diet (HFD) increased solid tumor growth and lymph node (LN) metastasis in C57BL/6 mice injected with B16F10. To assess the effects of dietary carnosic acid on HFD-stimulated LN metastasis, male C57BL/6 mice were fed a control diet (CD, 10 kcal% fat) or a HFD (60 kcal% fat) containing 0, 0.02, or 0.04% of carnosic acid for 21 weeks. B16F10 was subcutaneously injected 16 weeks after the initiation of feeding. The body weight and solid tumor growth were significantly increased in the HFD group as compared to the CD group, and these increases were suppressed by dietary carnosic acid. Lean body mass and body fat mass were estimated by dual energy X-ray absorptiometry. The body fat mass was tremendously increased in HFD-fed mice, and this increase was substantially decreased in a carnosic acid-dose dependent manner. A small but significant increase in lean body mass was noted in HFD-fed mice, which was not altered by dietary carnosic acid. Fasting blood glucose was markedly increased in HFD-fed mice, which was suppressed by 0.04% dietary carnosic acid. The tumor was resected 3 weeks after the B16F10 injection. Immunohistochemical staining of tumor tissues revealed that the expression of Ki67, platelet endothelial cell adhesion molecule-1, lymphatic vessel endothelial hyaluronan receptor-1, phospho-tyrosine phosphatase (a leukocyte marker), and vimentin was markedly increased in the HFD group as compared to the CD group, and these increases were blocked by carnosic acid. Two weeks after the tumor resection, LN metastasis was increased in mice fed HFD, and this increase was markedly suppressed by carnosic acid. In the present study, we demonstrate that dietary carnosic acid potently inhibits HFD-induced solid tumor growth and LN metastasis of B16F10 as well as tumor angiogenesis and lymphangiogenesis. Carnosic acid effectively suppresses HFD-induced body fat gains and fasting hyperglycemia, which may be parts of the mechanisms by which carnosic acid suppresses HFD-stimulated tumor progression.

Abstract
Abstract
The tumor microenvironment consists of a number of distinct cell types including tumor cells, fibroblasts, endothelial cells, immune cells, and adipocytes, and produces a wide variety of factors, which contribute to tumor progression. We previously observed that high-fat diet (HFD) feeding stimulates solid tumor growth and lymph node (LN) metastasis in mice subcutaneously injected with B16F10 melanoma cells. We also observed that HFD feeding increases the number of lipid vacuoles and M2-macrophage (M2-Mϕ)s as well as the expression of various cytokines/growth factors in tumor tissues. In the present study, we noted that HFD increased the expression of CCR7 in the tumor. The concentrations of CCL19 and CCL21, the CCR7 ligands, were significantly higher in the LN than those in tumor, and HFD feeding increased the concentrations of these ligands in the LN with negligible changes in the tumor tissue creating higher concentration gradients of these two ligands between the LN and tumor. In order to explore the interactions between tumor cells, adipocytes, lymphatic endothelial cell (LEC)s, and/or M2-Mϕs, we established in vitro co-culture models involving 3 distinct cell types. The mRNA levels of cytokines and growth factors were increased in B16F10 cells and M2-Mϕs when B16F10 cells, M2-Mϕs, and/or mature adipocyte (MA)s were co-cultured in a transwell system. Among these cytokines/growth factors, the mRNA levels of MCP-1 were synergistically increased in B16F10 cells when co-cultured with M2-Mϕs and MAs. The migration of monocytes was tremendously elevated when media conditioned by B16F10 cells/M2-Mϕs/MAs co-cultures was used as a chemoattractant. Furthermore, MAs increased the expression of CCR7 mRNA in B16F10 cells and the expression of CCL19 and CCL21 mRNAs in LECs. These results indicate that in HFD-fed mice, adipocytes induce MCP-1 expression and monocyte infiltration which play important roles in solid tumor growth and LN metastasis. Additionally, adipocyte-stimulated activation of CCL19, CCL21/CCR7 axis in lymphatic endothelial cells and tumor cells helps tumor cells to enter the lymphatic vessels and increased ligand concentration gradients between the LN and tumor facilitate tumor cell migration to the LN.
