Abstract
Antioxidant vanillin (4-hydroxy-3-methoxybenzaldehyde) is used as a flavoring in foods, beverages, and pharmaceuticals. Vanillin possesses various biological effects, such as antioxidant, anti-inflammatory, antibacterial, and anticancer properties. This study aimed to investigate the biological activities of vanillin purified from Adenophora triphylla var. japonica Hara on bone-forming processes. Vanillin treatment induced mineralization as a marker for mature osteoblasts, after stimulating alkaline phosphatase (ALP) staining and activity. The bone-forming processes of vanillin are mainly mediated by the upregulation of the bone morphogenetic protein 2 (BMP2), phospho-Smad1/5/8, and runt-related transcription factor 2 (RUNX2) pathway during the differentiation of osteogenic cells. Moreover, vanillin promoted osteoblast-mediated bone-forming phenotypes by inducing migration and F-actin polymerization. Furthermore, we validated that vanillin-mediated bone-forming processes were attenuated by noggin and DKK1. Finally, we demonstrated that vanillin-mediated antioxidant effects prevent the death of osteoblasts during bone-forming processes. Overall, vanillin has bone-forming properties through the BMP2-mediated biological mechanism, indicating it as a bone-protective compound for bone health and bone diseases such as periodontitis and osteoporosis.

Abstract
Obesity, a chronic disorder caused by excessive energy intake leading to fat accumulation in adipose tissue, increases the risk of severe diseases. Brassica rapa L. is known as a traditional vegetable in the Nagano area of Japan. C57BL/6 mice were randomly assigned to three groups, with different diets as follows: a normal diet, a Western diet (WD), and a WD plus B. rapa L. powder (BP) in a 56-day experiment. Brassica rapa L. supplementation reduced the body weight gain and lipid accumulation of mice significantly. The BP group also had higher fecal bile acid, total cholesterol, and triglyceride excretion levels compared with those in the other groups. The antiobesity effects of B. rapa L. were due to its binding with cholesterol and fat, and possibly enhancing the bile acid excretion and modulating gut microbiota, suggesting that B. rapa L. could be a functional vegetable with potential uses in targeting obesity.

Abstract
The Bardet–Biedl Syndrome 7 (Bbs7) gene was identified as the most likely candidate gene causing juvenile obesity in the Berlin Fat Mouse Inbred (BFMI) line. Bbs7 expression is significantly lower in the brain, adipose tissue, and liver of BFMI mice compared to lean C57BL/6NCrl (B6N) mice. A DNA sequence comparison between BFMI and B6N revealed 16 sequence variants in the Bbs7 promoter region. Here, we tested if these mutations contribute to the observed differential expression of Bbs7. In a cell-based dual-luciferase assay, we compared the effects of the BFMI and the B6N haplotypes of different regions of the Bbs7 promotor on the reporter gene expression. A single-nucleotide polymorphism (SNP) was identified causing a significant reduction in the reporter gene expression. This SNP (rs29947545) is located in the 5′ UTR of Bbs7 at Chr3:36.613.350. The SNP is not unique to BFMI mice but also occurs in several other mouse strains, where the BFMI allele is not associated with lower Bbs7 transcript amounts. Thus, we suggest a compensatory mutation in the other mouse strains that keeps Bbs7 expression at the normal level. This compensatory mechanism is missing in BFMI mice and the cell lines tested.

Abstract
Chlorella has been identified as a rich source of unsaturated fatty acids. Since the antiobesity effects of unsaturated fatty acids have been well documented; therefore, we explored the antiobesity actions of chlorella unsaturated fatty acids (C.UFAs) in the current study. The obtained results demonstrated C.UFAs, which contain abundant linoleic acid, could retard body weight gain (reducing body weigh by 13.93% after 16 weeks of treatment), improve blood glucose (19.29% lower) and lipid profile (23.45% lower in TG, 8.76% lower in TC) compared to high-fat diet-fed C57BL/6J mice. The possible underlying mechanisms might involve reducing hepatic lipid accumulation via down-regulation of lipogenic genes (PPARγ, C/EBPα, LPL, aP2, FAS, and SREBP-1c) and up-regulation of lipolytic gene (adiponectin). We also demonstrate C.UFAs could reduce HFD-induced adipocyte hypertrophy via activation of AMPK signaling pathway in adipose tissue and liver. In summary, our study highlights the potential of C.UFAs as a functional food for obesity management. PRACTICAL APPLICATION: Chlorella has already been commercialized as a functional food antiobesity function. In the current study, the unsaturated fatty acids isolated from chlorella were found to exert beneficial effects on hyperglycemia, hyperlipidemia, hepatic steatosis, and adipocyte hypertrophy in high-fat diet-fed mice. This may provide theoretical foundation for developing novel chlorella-based functional foods.

Abstract
Since the potential of (3:1) mixtures of Atractylodes macrocephala and Amomum villosum extracts has been proposed in the management of obesity, the purpose of present study was to investigate the effects of AME:AVE (3:1) mixture on weight loss, obesity-related biochemical parameters, adipogenesis and lipogenesis related proteins in 3T3-L1 cells and HFD-induced obesity in a mouse model. Treatment with AME:AVE (3:1) mixture inhibited lipid accumulation. Furthermore, the treatment with 75 and 150 mg/kg of AME:AVE (3:1) significantly decreased the body weight gain, white adipose tissue (WAT) weight, and plasma glucose level in HFD-induced obese mice. Moreover, treatment with 75 and 150 mg/kg AME:AVE (3:1) also significantly lowered the size of adipocytes in adipose tissue and reduced the lipid accumulation in liver. AME:AVE (3:1) treatment significantly decreased the expression of proteins related to adipogenesis and lipogenesis in 3T3-L1 adipocytes and WAT of HFD-induced obese mice. These results suggest that the AME:AVE herbal mixture (3:1) has anti-obesity effects, which may be elicited by regulating the expression of adipogenesis and lipogenesis-related proteins in adipocytes and WAT in HFD-induced obesity in mice.

Abstract
Objectives It is reported that tumor-associated macrophages (TAMs) contribute to cancer progression by promoting tumor growth and metastasis. The purpose of this study is to investigate the effect of different fractions of Adenophora triphylla var. japonica (AT) on the polarization of macrophages into the M2 phenotype, a major phenotype of TAMs. Methods We isolated hexane, ethyl acetate, and butanol fractions from crude ethanol extract of AT. The cytotoxicity of AT in RAW264.7 cells was examined by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. RAW264.7 cells were polarized into the M2 phenotype by treatment with interleukin (IL)-4 and IL-13. The expression of M2 macrophage marker genes was detected by reverse transcription polymerase chain reaction (RT-PCR). The phosphorylation level of signal transducer and activator of transcription 6 (STAT6) was investigated by western blot analysis. The migration of Lewis lung carcinoma (LLC) cells was examined by transwell migration assay using conditioned media (CM) collected from RAW264.7 cells as a chemoattractant. Results Among various fractions of AT, the ethyl acetate fraction of AT (EAT) showed the most significant suppressive effect on the mRNA expression of M2 macrophage markers, including arginase-1, interleukin (IL)-10 and mannose receptor C type 1 (MRC-1), up-regulated by treatment of IL-4 and IL-13. In addition, EAT suppressed the phosphorylation of STAT6, a critical regulator of IL-4 and IL-13-induced M2 macrophage polarization. Finally, the increased migration of Lewis lung carcinoma (LLC) cells by CM from M2-polarized RAW264.7 cells was reduced by CM from RAW264.7 cells co-treated with EAT and M2 polarization inducers. Conclusion We demonstrated that EAT attenuated cancer cell migration through suppression of macrophage polarization toward the M2 phenotype. Additional preclinical or clinical researches are needed to evaluate its regulatory effects on macrophage polarization and anti-cancer activities.

Abstract
Inhalation of diesel exhaust particulate (DEP) causes oxidative stress-induced lung inflammation. This study investigated the protective effects of TF-343, an antioxidant and anti-inflammatory agent, in mouse and cellular models of DEP-induced lung inflammation as well as the underlying molecular mechanisms. Mice were intratracheally instilled with DEP or vehicle (0.05% Tween 80 in saline). TF-343 was orally administered for 3 weeks. Cell counts and histological analysis of lung tissue showed that DEP exposure increased the infiltration of neutrophils and macrophages in the peribronchial/perivascular/interstitial regions, with macrophages harboring black pigments observed in alveoli. TF-343 pretreatment reduced lung inflammation caused by DEP exposure. In an in vitro study using alveolar macrophages (AMs), DEP exposure reduced cell viability and increased the levels of intracellular reactive oxygen species and inflammatory genes (IL-1β, inhibitor of nuclear factor- (NF-) κB (IκB), and Toll-like receptor 4), effects that were reduced by TF-343. A western blot analysis showed that the IκB degradation-induced increase in NF-κB nuclear localization caused by DEP was reversed by TF-343. In conclusion, TF-343 reduces DEP-induced lung inflammation by suppressing NF-κB signaling and may protect against adverse respiratory effects caused by DEP exposure.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Adenophora triphylla var. japonica is frequently used as an oriental medicinal plant in Korea, China, and Japan for its anti-inflammatory, antitussive, and hepatoprotective effects. AIM OF THE STUDY In the present study, the antitussive, expectorant, and anti-inflammatory effects of AR powder were investigated using animal models to evaluate their potential to treat respiratory disorders. MATERIALS AND METHODS AR powder was administered orally to mice once daily for 11 days, at dose levels of 400, 200, and 100 mg/kg. Theobromine (TB), ambroxol (AM) and dexamethasone (DEXA) were used as standard drugs for antitussive effects, expectorant effects and anti-inflammatory effects, respectively. Evaluations of antitussive effects were based on changes in body weight, the number of cough responses and the histopathology of the lung and trachea. Expectorant effects were based on changes in the body weight, macroscopic observations of body surface redness, the mucous secretion of the trachea and histopathology of lung (secondary bronchus). Anti-inflammatory effects were based on changes in the body weight, macroscopic observations involving redness and edema of the treated ear, absolute and relative ear weights and histopathology of the treated ears. RESULTS Allergic acute inflammation and coughing induced by exposure to NH4OH and symptoms of xylene-induced contact dermatitis were significantly inhibited by treatment with AR powder in a dose-dependent manner. Histological analyses revealed that AR powder decreased the OD values in trachea lavage fluid, reduced body surface redness, thicknesses of intrapulmonary secondary bronchus mucosa, and the number of PAS-positive mucous producing cells. Overall, AR powder administered at 200 mg/kg displayed superior antitussive and expectorant effects as compared to TB (50 mg/kg), and AM (250 mg/kg). At the highest concentration (400 mg/kg) AR powder displayed only moderately improved anti-inflammatory activities as compared to DEXA (1 mg/kg). CONCLUSION The results obtained in this study suggest that AR powder exerts dose-dependent, favorable antitussive, expectorant, and anti-inflammatory activities achieved through modulation of the activity of mast cells and respiratory mucous production. Therefore, AR powder may serve as a therapeutic agent in various respiratory disorders, especially those that occur as a result of environmental toxicants.

Abstract
Cornus kousa the Korean dogwood has been traditionally used in East Asia as therapeutic traditional medicine however biological activities of Cornus kousa have not been investigated previously. The aim of the present study was to evaluate anti-obesity activities coupled with anti-angiogenic activities of anthocyanins rich fraction of ethanolic leaf extract of Cornus kousa (ELECk) in HUVECs and 3T3- L1 cells. Dried plants leaves were extracted with 70% ethanol and anthocyanin fraction (AnT Fr) was obtained by eluting the ethanolic extract through non-polar macroporous resin and further purification by HPLC. Antiangiogenic activities were determined by antiproliferative effect of AnT Fr on HUVECs. In the presence of various concentrations of AnT Fr, 3T3-L1 preadipocytes were induced to differentiate. Lipid accumulation in differentiated adipocytes were quantified by Oil-Red O staining. AnT Fr significantly suppressed angiogenesis by inhibiting proliferation and tube formation of HUVECs via downregulating VEGRF 2, PI3K, β-catenin, NF-kB, and Akt1 in a dose dependent manner. AnT Fr inhibited lipid accumulation by down-regulating adipogenesis and lipogenesis promoting signaling proteins, PPARγ, CCAAT, C/EBPα, aP2, FAS, and LPL, however enhanced AMPK activation to p-AMPK in 3T3 cells quantified and expressed by western blotting. AnT Fr inhibit lipid accumulation by regulating adipogenesis and lipogenesis related genes and signaling proteins. The anti-obesity activities exerted by Cornus kousa are associated with antiangiogenic activities of anthocyanins rich fraction of Cornus kousa. Hence the presence of bioactive anthocyanins, Cornus kosa, is a good candidate for nutraceutical and pharmaceutical formulation for treating or controlling obesity.

Abstract
CQR-300 inhibited lipid accumulation in 3T3-L1 adipocytes. CQR-300 inhibited the differentiation of adipocytes by regulating adipogenesis. CQR-300 reduced fatty acids and triglyceride accumulation via downregulating lipogenesis.
The objective of this study was to evaluate the anti-obesity activity and the action mechanism of Cissus quadrangularis extracts (CQR-300) in 3T3-L1 adipocytes. Cissus quadrangularis was extracted with hot water, resulting in CQR-300. The anti-obesity activity of CQR-300 in 3T3-L1 adipocytes was examined by Oil-red O staining. Possible mechanisms of CQR-300 in 3T3-L1 adipocytes were determined by real-time PCR and western blot. Treatment with CQR-300 inhibited lipid accumulation without showing cytotoxicity to 3T3-L1 adipocytes. Furthermore, CQR-300 decreased adipogenesis/lipogenesis-related mRNA expression levels of fatty acid binding protein (aP2), fatty acid synthase (FAS), lipoprotein lipase (LPL), stearoyl-CoA desaturase-1 (SCD-1), and acetyl-CoA carboxylase (ACC). CQR-300 also down-regulated expression levels of adipogenesis/lipogenesis-associated proteins, including peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer-binding protein α (C/EBPα), sterol regulatory element binding protein-1c (SREBP-1c), and FAS. It’s also up-regulated the expression level of phosphorylated-AMPK (p-AMPK). Collectively, these results suggested that CQR-300 might have an anti-obesity effect by its ability to decrease expression levels of adipogenesis/lipogenesis-related genes and proteins.

Abstract
Obesity, the excessive accumulation of lipids in the body, is closely associated with many prevalent human disorders. Continued efforts to identify plant extracts that exhibit anti-obesity effects have drawn much attention. This study investigated whether a Polygala tenuifolia extract (PTE) possesses anti-obesity activity and how PTE may affect liver gene expression and gut microbiota. We used 3T3-L1 adipocytes and a high-fat diet–induced obese mouse model to determine the effects of PTE on lipid accumulation. Next-generation sequencing analysis of liver gene expression and gut microbiota profiles following PTE treatment were conducted to elucidate possible mechanisms. We found that treatment of fully differentiated 3T3-L1 adipocytes with PTE inhibited lipid accumulation in the cells through reducing lipid formation and triglyceride content and by increasing lipase activity. No cytotoxicity was observed from the PTE treatment. After 5 weeks of treatment with PTE, the increased body weight, elevated serum triglyceride content, and liver steatosis in the high-fat diet–induced obese mice were each reduced. Liver transcriptomic analysis revealed that expression of genes involved in lipid and cholesterol metabolism was significantly altered. The low-grade chronic inflammation of obesity caused by a high-fat diet was also decreased after PTE treatment. In addition, treatment with PTE improved the relatively low Bacteroidetes/Firmicutes ratio in the gut of high-fat diet–fed mice through enrichment of the Proteobacteria population and reduction of the Deferribacteres population. In conclusion, treatment with PTE inhibited lipid accumulation by inducing the expression of the master transcription factor PPARα, attenuated the low-grade chronic inflammation of obesity, and also altered gut microbiota profiles. These results indicate that PTE has the potential to be developed into an anti-obesity food supplement and therapy.
