Calvarial Reconstruction With Autologous Sagittal Split Rib Bone Graft and Latissimus Dorsi Rib Myoosseocutaneous Free Flap.

OBJECTIVE: Cranioplasty is essential because cranial defects cause cosmetic and functional problems, and neurologic sequalae in patients. However, reconstruction options are limited in patients with unfavorable conditions. This study aimed to review our experience with skull defect reconstruction using autogenous bone with sagittal split rib bone grafts or latissimus dorsi rib myoosseocutaneous free flaps. METHODS: Patients who underwent autogenous bone graft for cranial defect coverage from December 2011 to November 2015 at our institution were reviewed. Rib bone graft or latissimus dorsi rib myoosseocutaneous free flaps were done to cover the defect. The patient follow-up period ranged from 3 months to 7 years. RESULTS: There were 6 patients, with 9 surgeries. Two cases of latissimus dorsi rib myoosseocutaneous free flap procedures were performed in 2 patients and 7 sagittal split rib bone grafts were performed in 6 patients. There were no postoperative infections in any patients, despite 4 patients had previous surgical site infection histories. Two patients with neurologic sequalae showed improvement after the surgeries. CONCLUSION: Sagittal split rib bone graft and latissimus dorsi rib myoosseocutaneous free flap procedures could be fine options for calvarial reconstruction of defects under the unfavorable conditions of bilateral cranial defects or previous infection history.

Effect of Angelica gigas Nakai Ethanol Extract and Decursin on Human Pancreatic Cancer Cells.

Pancreatic cancer (PC) is one of the most severe cancers, and its incidence and mortality rates have steadily increased in the past decade. In this study, we demonstrate the effect of Angelica gigas Nakai extract on pancreatic ductal adenocarcinoma cells. We prepared A. gigas Nakai ethanol extract (AGE) using roots of A. gigas Nakai and detected its active compound decursin from AGE by ultra-performance liquid chromatography analysis. AGE and decursin significantly decreased viability and colony formation of PANC-1 and MIA PaCa-2 cells. AGE and decursin induced G0/G1 phase arrest through downregulation of cyclin D1 and cyclin-dependent kinase 4 (CDK4). Caspase-3-dependent apoptosis of PANC-1 cells was promoted by AGE and decursin. Additionally, nontoxic concentrations of AGE and decursin treatment could suppress matrix metalloproteinase (MMP)-2 and MMP-9 expression and activity by inhibiting p38 phosphorylation. Taken together, this study demonstrates that AGE and decursin have potential properties to be considered in PC treatment.

Arctigenin Inhibits Adipogenesis by Inducing AMPK Activation and Reduces Weight Gain in High-Fat Diet-Induced Obese Mice.

Although arctigenin (ARC) has been reported to have some pharmacological effects such as anti-inflammation, anti-cancer, and antioxidant, there have been no reports on the anti-obesity effect of ARC. The aim of this study is to investigate whether ARC has an anti-obesity effect and mediates the AMP-activated protein kinase (AMPK) pathway. We investigated the anti-adipogenic effect of ARC using 3T3-L1 pre-adipocytes and human adipose tissue-derived mesenchymal stem cells (hAMSCs). In high-fat diet (HFD)-induced obese mice, whether ARC can inhibit weight gain was investigated. We found that ARC reduced weight gain, fat pad weight, and triglycerides in HFD-induced obese mice. ARC also inhibited the expression of peroxisome proliferator-activated receptor gamma (PPARγ) and CCAAT/enhancer-binding protein alpha (C/EBPα) in in vitro and in vivo. Furthermore, ARC induced the AMPK activation resulting in down-modulation of adipogenesis-related factors including PPARγ, C/EBPα, fatty acid synthase, adipocyte fatty acid-binding protein, and lipoprotein lipase. This study demonstrates that ARC can reduce key adipogenic factors by activating the AMPK in vitro and in vivo and suggests a therapeutic implication of ARC for obesity treatment. J. Cell.

Anti-adipogenic effect of Glycoside St-E2 and Glycoside St-C1 isolated from the leaves of Acanthopanax henryi (Oliv.) Harms in 3T3-L1 cells.

Acanthopanax henryi (Oliv.) Harms has been used in the treatment of arthritis, rheumatism, and abdominal pain. This study evaluated whether natural compounds isolated from the leaves of A. henryi (Oliv.) Harms could inhibit adipocyte differentiation by regulating transcriptional factors such as peroxisome proliferator-activated receptor γ (PPARγ) and CCAAT/enhancer-binding protein α (C/EBPα). AMP-activated protein kinase (AMPK) activity was also evaluated. Among the several compounds isolated from the leaves of A. henryi (Oliv.) Harms, Glycoside St-C1 and Glycoside St-E2 significantly decreased lipid accumulation and the expressions of PPARγ and C/EBPα. Glycoside St-C1 and Glycoside St-E2 were found to activate AMPK when they regulated PPARγ and C/EBPα. Results confirmed that Glycoside St-C1 and Glycoside St-E2 isolated from the leaves of A. henryi (Oliv.) Harms can inhibit adipogenesis through the AMPK-PPARγ-C/EBPα mechanism. Thus, this study suggests that Glycoside St-C1 and Glycoside St-E2 have a therapeutic effect due to activation of the AMPKα.

Arctigenin Inhibits Lung Metastasis of Colorectal Cancer by Regulating Cell Viability and Metastatic Phenotypes.

Arctigenin (ARC) has been shown to have an anti-cancer effect in various cell types and tissues. However, there have been no studies concerning metastatic colorectal cancer (CRC). In this study, we investigated the anti-metastatic properties of ARC on colorectal metastasis and present a potential candidate drug. ARC induced cell cycle arrest and apoptosis in CT26 cells through the intrinsic apoptotic pathway via MAPKs signaling. In several metastatic phenotypes, ARC controlled epithelial-mesenchymal transition (EMT) through increasing the expression of epithelial marker E-cadherin and decreasing the expressions of mesenchymal markers; N-cadherin, vimentin, ß-catenin, and Snail. Moreover, ARC inhibited migration and invasion through reducing of matrix metalloproteinase-2 (MMP-2) and MMP-9 expressions. In an experimental metastasis model, ARC significantly inhibited lung metastasis of CT26 cells. Taken together, our study demonstrates the inhibitory effects of ARC on colorectal metastasis.

Effects of Ixeris dentata water extract and caffeic acid on allergic inflammation in vivo and in vitro.

BACKGROUND: Ixeris dentata Nakai has been used for the treatment of mithridatism, calculous, indigestion, pneumonia, hepatitis, and tumors in Korea, China, and Japan. However, the effect of a water extract of Ixeris dentata (ID) and its molecular mechanism on allergic inflammation has not been elucidated. In this study, we attempted to evaluate the effects of ID and its major compound caffeic acid on allergic inflammation in vivo and in vitro. METHODS: ID was applied to 2, 4-dinitrofluorobenzene (DNFB)-induced atopic dermatitis (AD)-like skin lesion mice and immune cell infiltration, cytokine production, and the activation of mitogen-activated protein kinases (MAPKs) were investigated. Moreover, the effect of ID on compound 48/80-induced anaphylactic shock was investigated in a mouse model. The human keratinocyte cell line (HaCaT cells) and human mast cells (HMC-1) were treated with ID or caffeic acid to investigate the effects on the production of chemokines and proinflammatory cytokines and on the activation of MAPKs. RESULTS: ID inhibited the serum levels of IgE and interleukin (IL)-1ß in DNFB-induced AD-like skin lesion mouse models and suppressed anaphylactic shock in the mouse models. ID and caffeic acid inhibited the production of chemokines and adhesion molecules in HaCaT cells. In addition, ID reduced the release of tumor necrosis factor-α and IL-8 via the inhibition of MAPKs phosphorylation in HMC-1 cells. CONCLUSIONS: These results suggest that ID is a potential therapeutic agent for allergic inflammatory diseases, including dermatitis.

The antiinflammatory mechanism of Igongsan in mouse peritoneal macrophages via suppression of NF-κB/Caspase-1 activation.

UNLABELLED: Igongsan (IGS), which is an herbal prescription composed of five different herbs, Ginseng Radix (root of Panax ginseng, Araliaceae), Atractylodis Rhizoma Alba (rhizome of Atractylodes Macrocephala, Compositae), Poria Sclerotium (sclerotium of Poria cocos, Polyporaceae), Glycyrrhizae Radix et Rhizoma (root and rhizome of Glycyrrhiza uralensis, Leguminosae), and Citri Unshius Pericarpium (Peel of Citrus unshiu, Rutaceae), has been traditionally used in Korea to treat a variety of inflammatory diseases. In this study, we investigated to elucidate the mechanism responsible for IGS's antiinflammatory effect in mouse peritoneal macrophages. The findings demonstrate that IGS inhibited the production of inflammatory cytokine and prostaglandins E2 . IGS inhibited the enhanced levels of cyclooxygenase-2 and inducible NO synthase caused by lipopolysaccharide (LPS). Additionally, it was shown that the antiinflammatory effect of IGS is through regulating the activation of nuclear factor-kappa B and caspase-1 in LPS-stimulated mouse peritoneal macrophages. These results provide novel insights into the pharmacological actions of IGS as a potential candidate for development of new drugs to treat inflammatory diseases. DISCUSSION AND CONCLUSION: These results provide novel insights into the pharmacological actions of IGS as a potential candidate for development of new drugs to treat inflammatory diseases.

Activation of lipopolysaccharide-TLR4 signaling accelerates the ototoxic potential of cisplatin in mice.

Dysfunction in immune surveillance during anticancer chemotherapy of patients often causes weakness of the host defense system and a subsequent increase in microbial infections. However, the deterioration of organ-specific function related to microbial challenges in cisplatin-treated patients has not yet been elucidated. In this study, we investigated cisplatin-induced TLR4 expression and its binding to LPS in mouse cochlear tissues and the effect of this interaction on hearing function. Cisplatin increased the transcriptional and translational expression of TLR4 in the cochlear tissues, organ of Corti explants, and HEI-OC1 cells. Furthermore, cisplatin increased the interaction between TLR4 and its microbial ligand LPS, thereby upregulating the production of proinflammatory cytokines, such as TNF-α, IL-1ß, and IL-6, via NF-κB activation. In C57BL/6 mice, the combined injection of cisplatin and LPS caused severe hearing impairment compared with that in the control, cisplatin-alone, or LPS-alone groups, whereas this hearing dysfunction was completely suppressed in both TLR4 mutant and knockout mice. These results suggest that hearing function can be easily damaged by increased TLR expression and microbial infections due to the weakened host defense systems of cancer patients receiving therapy comprising three to six cycles of cisplatin alone or cisplatin combined with other chemotherapeutic agents. Moreover, such damage can occur even though patients may not experience ototoxic levels of cumulative cisplatin concentration.

Association between P478S polymorphism of the filaggrin gene & atopic dermatitis.

BACKGROUND & OBJECTIVES: Atopic diseases, including atopic dermatitis (AD), allergy and asthma, are complex diseases resulting from the effect of multiple genetic and interacting environmental factors on their pathophysiology. The genetic basis is incompletely understood; however, recent studies have shown an association between loss-of-function variants of the filaggrin gene (FLG) and atopic dermatitis. The aim of this study was to determine whether FLG variants can serve as a predictor for atopic diseases in Korean individuals. METHODS: A total of 648 subjects were genotyped for the FLG P478S (rs11584340, C/T base change) polymorphism (322 patients and 326 controls). Serum levels of free fatty acids (FFA) and IgE were later stratified to determine the effects of the FLG polymorphism on AD. RESULTS: A significant difference in genotype frequency was found between AD patients and controls in the FLG P478S polymorphism. The FLG P478S T allele carrier (TT+TC) was associated with AD risk (odds ratio = 1.877, 95% confidence interval 1.089 to 3.234). In addition, the P478S T allele was related to high levels of FFA in AD patients (471.79 ± 298.96 vs. 333.54 ± 175.82 µg eq/l, P <0.05). INTERPRETATION & CONCLUSIONS: The results of the present study suggest that the FLG P478S polymorphism alone and combined with other factors influences FFA levels and increases the susceptibility to AD.

Saengmaeksan inhibits inflammatory mediators by suppressing RIP-2/caspase-1 activation.

BACKGROUND AND OBJECTIVES: Saengmaeksan (SMS) is a Korean herbal prescription consisting of three different herbal drugs: Liriopis Tuber (tuber of Liriope platyphylla, Liliaceae), Ginseng Radix (root of Panax ginseng) and Schisandrae Fructus (fruit of Schisandra chinensis). SMS is commonly used in Korea to treat various diseases that involve the respiratory and cardiovascular systems. However, to date, the mechanism underlying the anti-inflammatory effects of SMS is not clearly understood. In this study, we attempt to determine the effects of SMS on lipopolysaccharide (LPS)-induced inflammatory responses in mouse peritoneal macrophages. METHODS: Cell viability was measured by using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, and nitric oxide (NO) levels were measured by using Griess reagent. The tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels secreted by the cells were measured using a modified enzyme-linked immunosorbent assay. Expression of cyclooxygenase (COX)-2 and nuclear factor-kappa B (NF-κB), respectively was investigated using a western blot analysis. A caspase colorimetric assay kit was used to assay enzymatic caspase-1 activity. RESULTS: The findings of this study showed that SMS reduced TNF-α and IL-6 production induced by LPS. During the inflammatory process, COX-2 and NO levels were increased in mouse peritoneal macrophages, but SMS decreased the enhanced levels of COX-2 and the production of NO. In addition, SMS suppressed the activation of NF-κB and receptor interacting protein-2/caspase-1. DISCUSSION AND CONCLUSION: Our results provide novel insights into the pharmacological actions of SMS, a molecule that can potentially be exploited in the treatment of inflammatory diseases.

Proinflammatory cytokine IL-1 ß polymorphisms in sudden sensorineural hearing loss.

The cause and pathogenesis of sudden sensorineural hearing loss (SSNHL) remain unknown. IL-1ß is one of the most powerful inflammatory cytokines. The aim of this study was to evaluate the relationships between interleukin-1 ß (IL-1ß) gene polymorphisms (-511 C/T and +3953 C/T) in patients with SSNHL. One hundred two patients affected by SSNHL and 595 controls were genotyped for IL-1ß gene polymorphisms. The polymorphisms were analyzed by polymerase chain reaction amplification and DNA fragment separation via electrophoresis. Compared to controls, the IL-1ß (+3953) T allele increased the relative risk of SSNHL in subjects with IL-1ß (-511) TT genotype (p = 0.022, OR = 9.111, 95% CI = 1.441-57.618). In this study, polymorphisms in the IL-1ß -511 and IL-1ß +3953 loci were assessed for evidence of association with SSNHL. From this assessment, a significant difference in carriage of both the IL-1ß -511 T allele and the IL-1ß +3953 T allele was observed between SSNHL and controls. This suggests that the IL-1ß -511 and +3953 loci may play an important role in the etiopathogenesis of SSNHL.

The ameliorative effect of sophoricoside on mast cell-mediated allergic inflammation in vivo and in vitro.

Sophoricoside exhibits numerous pharmacological effects, including anti- inflammatory and anti-cancer actions, yet the exact mechanism that accounts for the anti-allergic effects of sophoricoside is not completely understood. The aim of the present study was to elucidate whether and how sophoricoside modulates the mast cell-mediated allergic inflammation in vitro and in vivo. We investigated the pharmacological effects of sophoricoside on both compound 48/80 or histamine-induced scratching behaviors and 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis in mice. Additionally, to find a possible explanation for the anti-inflammatory effects of sophoricoside, we evaluated the effects of sophoricoside on the production of histamine and inflammatory cytokines and activation of nuclear factor-κB (NF-κB) and caspase-1 in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). The finding of this study demonstrated that sophoricoside reduced compound 48/80 or histamine-induced scratching behaviors and DNCB-induced atopic dermatitis in mice. Additionally, sophoricoside inhibited the production of inflammatory cytokines as well as the activation of NF-κB and caspase-1 in stimulated HMC-1. Collectively, the findings of this study provide us with novel insights into the pharmacological actions of sophoricoside as a potential molecule for use in the treatment of allergic inflammation diseases.

Association of interleukin-18 gene polymorphism with body mass index in women.

BACKGROUND: Interleukin (IL)-18 is an important regulator of innate and acquired immune responses and has multiple roles in chronic inflammation and autoimmune disorders. Obesity is characterized by low- grade chronic inflammation. IL-18 has been suggested as an adipogenic cytokine that is associated with excess adiposity. The purpose of this study is to evaluate the relationship between IL-18 gene polymorphisms (-137 G/C and -607 C/A) and obesity. METHODS: All 680 subjects were genotyped for the polymorphisms of IL-18 gene promoters (at positions -137 G/C and -607 C/A) using a polymerase chain reaction (271 cases with BMI ≥25 kg/m² and 409 controls with BMI <25 kg/m²). A chi-square test was used to compare the genotype and allele frequencies between the cases and control populations. RESULTS: Analyses of the genotype distributions revealed that IL-18 -607 C/A polymorphism was associated with an increase in body mass index in obese women in the Korean population (chi(2) = 12.301, df = 2, p = 0.015). CONCLUSION: Carriage of the A allele at position -607 in the promoter of the IL-18 gene may have a role in the development of obesity.

The therapeutic effect of chelidonic acid on ulcerative colitis.

Chelidonic acid (CA), a constituent of Chelidonium majus L., has many pharmacological effects, including mild analgesic and antimicrobial effects. However, the effects of CA on intestinal inflammation and the molecular mechanisms responsible are poorly understood. The aim of this study was to investigate the protective effects of CA against dextran sulfate sodium (DSS)-induced ulcerative colitis (UC). Mice treated with DSS displayed obvious clinic signs, such as, body weight loss and a shortening of colon length, but the administration of CA attenuated both of these signs. Additionally, CA was found to regulate levels of interleukin-6 and tumor necrosis factor-α in serum. In colonic tissues, prostaglandin E(2) (PGE(2)) production levels and cyclooxygenase-2 (COX-2) and hypoxia induced factor-1α (HIF-1α) expression levels were increased by DSS, but CA attenuated increases in COX-2 and HIF-1α levels. These results provide novel insights into the pharmacological actions of CA and its potential use for the treatment of intestinal inflammation.

Piperine inhibits lipopolysaccharide-induced maturation of bone-marrow-derived dendritic cells through inhibition of ERK and JNK activation.

Piperine, one of the main components of Piper longum Linn. and P. nigrum Linn., is a plant alkaloid with a long history of medicinal use. Piperine has been shown to modulate the immune response, but the mechanism underlying this modulation remains unknown. Here, we examined the effects of piperine on lipopolysaccharide (LPS)-induced inflammatory responses in bone-marrow-derived dendritic cells (BMDCs). Piperine significantly inhibited the expression of major histocompatibility complex class II, CD40 and CD86 in BMDCs in a dose-dependent manner. Furthermore, piperine treatment led to an increase in fluorescein-isothiocyanate-dextran uptake in LPS-treated dendritic cells and inhibited the production of tumour necrosis factor alpha and interleukin (IL)-12, but not IL-6. The inhibitory effects of piperine were mediated via suppression of extracellular signal-regulated kinases and c-Jun N-terminal kinases activation, but not p38 or nuclear factor-κB activation. These findings provide insight into the immunopharmacological role of piperine.

Dehydroevodiamine inhibits lung metastasis by suppressing survival and metastatic abilities of colorectal cancer cells.

BACKGROUND: Despite the rising 5-year survival rate of colorectal cancer (CRC) patients, the survival rate decreases as the stage progress, and a low survival rate is highly associated with metastasis. PURPOSE: The purpose of our study is to investigate the effect of dehydroevodiamine (DHE) on the lung metastasis of CRC and the proliferation of CRC cells. STUDY DESIGN: Cell death was confirmed after DHE treatment on several CRC cell lines. The mechanism of cell cytotoxicity was found using flow cytometry. After that, the expression of the proteins or mRNAs related to the cell cytotoxicity was confirmed. Also, anti-metastatic ability of DHE in CRC cells was measured by checking the expression of Epithelial to Mesenchymal Transition (EMT) markers. Lung metastasis mouse model was established, and DHE was administered orally for 14 days. RESULTS: DHE suppressed the viability of HCT116, CT26, SW480, and LoVo cells. DHE treatment led to G2/M arrest via a reduction of cyclin B1/CDK1 and caspase-dependent apoptosis. It also induced autophagy by regulating LC3-II and beclin-1 expression. Additionally, migration and invasion of CRC cells were decreased by DHE through regulation of the expression of EMT markers. Oral administration of DHE could inhibit the lung metastasis of CT26 cells in an in vivo model. CONCLUSION: Our study demonstrated that DHE has a potential therapeutic effect on colorectal cancer metastasis.

Vanillic acid inhibits inflammatory mediators by suppressing NF-κB in lipopolysaccharide-stimulated mouse peritoneal macrophages.

Vanillic acid is a benzoic acid derivative that is used as a flavoring agent. It is an oxidized form of vanillin. At present, the mechanisms by which vanillic acid exerts its anti-inflammatory effects are incompletely understood. In this study, we attempted to determine the effects of vanillic acid on lipopolysaccharide (LPS)-induced inflammatory responses in mouse peritoneal macrophages. Our findings indicate that vanillic acid inhibits LPS-induced production of tumor necrosis factor (TNF)-α and interleukin (IL)-6. During the inflammatory process, the levels of cyclooxygenase (COX)-2 and nitric oxide (NO) increased in mouse peritoneal macrophages, but vanillic acid suppressed both the enhanced levels of COX-2 and the production of prostaglandin E(2) and NO. Moreover, vanillic acid suppressed the activation of nuclear factor-kappa B (NF-κB) and caspase-1. These results provide novel insights into the pharmacological actions of vanillic acid and are indicative of the potential use of this molecule in the treatment of inflammatory diseases.

The regulatory mechanism of ß-eudesmol is through the suppression of caspase-1 activation in mast cell-mediated inflammatory response.

ß-Eudesmol is sesquiterpenoid alcohol which contains the rhizome of Atractylodes lancea. Although it has multiple pharmacological effects, the anti-inflammatory effect of ß-eudesmol and its molecular mechanisms are poorly elucidated. In this study, we investigated the regulatory mechanism of ß-eudesmol on mast cell-mediated inflammatory response. The results indicated that ß-eudesmol inhibited the production and expression of interleukin (IL)-6 on phorbol 12-myristate 13-acetate and calcium ionophore A23187-stimulated human mast cell (HMC). In activated HMC-1 cells, ß-eudesmol suppressed activation of p38 mitogen-activated protein kinase (MAPKs) and nuclear factor-κB. In addition, ß-eudesmol suppressed the activation of caspase-1 and expression of receptor-interacting protein-2. These results provide new insights into the pharmacological actions of ß-eudesmol as a potential molecule for use in therapy in mast cell-mediated inflammatory diseases.

Inhibitory effects of the transgenic Panax ginsengs on phorbol ester plus A23187-induced IL-6 production and cyclooxygenase-2 via suppression of NF-κB and MAPKs in HMC-1.

Our previous studies have that demonstrated the overexpression of the squalene synthase gene enhances the biosynthesis of triterpene and phytosterol in Panax ginseng. The total ginsenoside contents in adventitious roots of transgenic P. ginseng were about 1.6-3-fold higher than those in the wild-type. In the present work, we have evaluated the anti-inflammatory effects of two types of transgenic P. ginseng (BS and SS) and the wild-type P. ginseng (GS) in a stimulated human mast cell line 1 (HMC-1). GS, BS, and SS inhibited not only the production of interleukin 6 (IL-6), but also the expression of cyclooxygenase-2 in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (PMACI)-stimulated HMC-1. Additionally, GS, BS, and SS suppressed the expression of the nuclear transcription factor κB and mitogen-activated protein kinases induced by PMACI. The anti-inflammatory effects of BS and SS were higher than that of GS. These results provide new insights into the pharmacological actions of transgenic P. ginseng as a potential molecule for use in therapy in mast cell-mediated inflammatory diseases.

Gomisin A Alleviates Obesity by Regulating the Phenotypic Switch between White and Brown Adipocytes.

Although gomisin A (GA) alleviates cancer and inflammation, its anti-obesity effect and the underlying mechanism have not yet been elucidated. Therefore, in this study, we aimed to elucidate the anti-obesity effects of GA by investigating the phenotypic changes involved in the browning and whitening of adipocytes. Here, obesity was induced to C57BL/6J mice using a high-fat diet (HFD). We administrated GA and checked weight changes for 12 weeks. We found that GA decreased the weight of weight gain, epididymal white adipose tissue (eWAT), and liver in the mice. In addition, the administration of GA elevated the levels of high-density lipoprotein (HDL)-cholesterol in the mice serum. Moreover, even after 12 weeks of treatment with GA, it did not cause any hepatic and renal toxicity. However, we found that GA induced the browning of eWAT and inhibited the whitening of brown adipose tissue. We further confirmed the anti-obesity mechanism of GA using 3T3-L1 cells, the human adipose mesenchymal stem cells (hAMSCs), and primary brown adipocytes (BAs) in vitroexperiments. We found that GA suppressed adipogenesis via the activation of AMP-activated protein kinase (AMPK). Furthermore, GA-induced browning by increasing the expression levels of uncoupling protein 1 (UCP1) in hAMSCs. The results of our study indicate that GA can inhibit weight gain by regulating the phenotypic changes involved in the browning and whitening of adipose tissues, which makes it a potential therapeutic agent for the treatment of obesity.
