Selective blockade of IL-21 by myricetin impedes T follicular helper cell differentiation by negatively regulating the JAK/STAT/Bcl-6 pathway in a rheumatoid arthritis animal model. 3 Biotech 2024; 14:25. [PMID: 38164247 PMCID: PMC10757705 DOI: 10.1007/s13205-023-03880-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Accepted: 12/05/2023] [Indexed: 01/03/2024] Open
Abstract
Interleukin (IL)-21 is a major lineage-defining factor that promotes Tfh cell differentiation. The current study investigated the molecular basis of myricetin, a flavonoid that impedes IL-21-mediated differentiation of Tfh cells in RA. Through high-throughput virtual screening of natural compounds that inhibit IL-21, we found that myricetin binds to IL-21 and hampers its interaction with IL-21 receptor (IL-21R). Our in vivo studies demonstrated that myricetin treatment ameliorated the clinical manifestations in adjuvant-induced arthritis (AIA) mice by reducing paw thickness and cellular infiltration. In addition, myricetin inhibited splenic Tfh cell differentiation and IL-21 production in AIA mice. Myricetin negatively regulates JAK/STAT signaling and the downstream Bcl-6 transcription factor at the molecular level, which arrests Tfh cell differentiation. Our current research proposal to target IL-21 with myricetin inevitably represents a new molecular approach that expedites new alternative drugs for rheumatoid arthritis therapy.

In Vitro Cell Dev Biol Anim 2023; 59:811-820. [PMID: 38032403 DOI: 10.1007/s11626-023-00827-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 10/30/2023] [Indexed: 12/01/2023]
Abstract
The synovial intimal lining is mainly governed by fibroblast-like synoviocytes (FLS), which portray a transformed tumor-like phenotype in rheumatoid arthritis (RA). Among the diverse cytokines that engender FLS, interleukin-21 (IL-21) was reported to stimulate hyperproliferation and perpetuate inflammation. Recently, choline kinase (ChoKα) has been reported to be an essential enzyme aiding RA-FLS hyperproliferation by altering phosphatidylcholine biosynthesis. The current study aimed to elucidate the therapeutic efficacy of myricetin, a flavonoid, in abating the IL-21-induced tumor-like phenotype of adjuvant-induced arthritis (AIA)-FLS via the ChoKα signaling cascade. Our results showed that myricetin suppressed IL-21 receptor expression and activation of the ChoKα signaling cascade (N-Ras, Ral-GDS, and PI3K) in IL-21-induced AIA-FLS. Consequently, myricetin treatment decreased ChoKα and PLD2 enzymatic activity and inhibited the proliferative, migratory, and invasive properties of AIA-FLSs. Our results demonstrated that myricetin could be a promising anti-arthritic compound by abating IL-21-induced hyperproliferation, migration, and invasive behavior of AIA-FLS by downregulating the ChoKα signaling cascade.

Abstract
Background/purpose Cell pyroptosis and gingival inflammation have been implicated in periodontitis progression. Our previous study revealed that AR-A014418, a pharmacological inhibitor of glycogen synthase kinase-3β (GSK-3β), can enhance the migratory and osteogenic differentiation abilities of rat dental pulp stem cells (rDPSCs). The present study aimed to explore the effect of AR on the inflammation of rDPSCs. Materials and methods The primary rDPSCs were isolated and identified by flow cytometry, as well as Oil red O and Alizarin Red S staining. The rDPSCs were cultured and exposed to lipopolysaccharide (LPS) before treating them with different concentrations of AR-A014418. The cell viability was detected using the CCK-8 assay. The generation and secretion of pro-inflammatory cytokines (IL-18, TNF-α, L-1β, and IL-6) were examined by qPCR and ELISA, respectively. To investigate the activation of the NLRP3 inflammasome, the expression levels of pro-caspase 1, cleaved caspase 1, as well as NLRP3 were analyzed by western blotting and immunofluorescence, respectively. Results In the rDPSCs, LPS prohibited cell viability and enhanced the generation and secretion of pro-inflammatory cytokines. LPS upregulated NLRP3 and cleaved caspase-1 protein levels and promoted ASC speck formation in the rDPSCs. AR-A014418 administration effectively blocked the LPS-induced inflammation of the rDPSCs in a dose-dependent way. Mechanistically, AR-A014418 significantly restrained the up-regulation of NLRP3 and cleaved caspase-1 in LPS-treated rDPSCs. Conclusion Collectively, our findings suggest that AR-A014418 significantly mitigates LPS-induced inflammation of rDPSCs by blocking the activation of the NLRP3 inflammasome.

Abstract
Clinical prevention is of utmost importance for the management of periodontal diseases. Periodontal disease starts with an inflammatory response in the gingival tissue, and results in alveolar bone destruction and subsequent tooth loss. This study aimed to confirm the anti-periodontitis effects of MKE. To confirm this, we studied its mechanism of action using qPCR and WB in LPS-treated HGF-1 cells and RANKL-induced osteoclasts. We found that MKE suppressed proinflammatory cytokine protein expression by inhibiting the TLR4/NF-κB pathway in LPS-PG-induced HGF-1 cells and blocking ECM degradation by regulating the expression of TIMPs and MMPs. We also confirmed that TRAP activity and multinucleated cell formation were reduced in RANKL-stimulated osteoclasts after exposure to MKE. These results were confirmed by inhibiting TRAF6/MAPK expression, which led to the suppression of NFATc1, CTSK, TRAP, and MMP expression at the gene and protein levels. Our results confirmed that MKE is a promising candidate for the management of periodontal disease based on its anti-inflammatory effects and inhibition of ECM degradation and osteoclastogenesis.

Abstract
Vasohibin-1 (VASH1) is a key inhibitor of vascular endothelial growth factor-induced angiogenesis. Although the involvement of VASH1 in various pathological processes has been extensively studied, its role in periodontal disease (PD) remains unclear. We aimed to investigate the role of VASH1 in PD by focusing on osteoclastogenesis regulation. We investigated VASH1 expression in PD by analyzing data from the online Gene Expression Omnibus (GEO) database and using a mouse ligature-induced periodontitis model. The effects of VASH1 on osteoclast differentiation and osteoclastogenesis-supporting cells were assessed in mouse bone marrow-derived macrophages (BMMs) and human gingival fibroblasts (GFs). To identify the stimulant of VASH1, we used culture broth from Porphyromonas gingivalis (Pg), a periopathogen. The GEO database and mouse periodontitis model revealed that VASH1 expression was upregulated in periodontitis-affected gingival tissues, which was further supported by immunohistochemistry and qRT-PCR analyses. VASH1 expression was significantly stimulated in GFs after treatment with the Pg broth. Direct treatment with recombinant VASH1 protein did not stimulate osteoclast differentiation in BMMs but did contribute to osteoclast differentiation by inducing RANKL expression in GFs through a paracrine mechanism. Small interfering RNA-mediated silencing of VASH1 in GFs abrogated RANKL-mediated osteoclast differentiation in BMMs. Additionally, VASH1-activated RANKL expression in GFs was significantly suppressed by MK-2206, a selective inhibitor of AKT. These results suggest that Pg-induced VASH1 may be associated with RANKL expression in GFs in a paracrine manner, contributing to osteoclastogenesis via an AKT-dependent mechanism during PD progression.

Abstract
Periodontitis is a chronic inflammatory disease characterized by tooth loss due to inflammation and the loss of alveolar bone. Periodontitis is closely related to various systemic diseases and is emerging as a global health problem. In this study, we investigated the anti-inflammatory effect of lactic acid bacteria (LAB) in vitro on Porphyromonas gingivalis (P. gingivalis) LPS-activated RAW264.7 and human gingival fibroblasts-1 (HGF-1) cells and the anti-osteoclastogenic effect of LAB on RANKL-induced RAW264.7 cells. All LAB strains (Lacticaseibacillus rhamnosus MG4706, MG4709, and MG4711) inhibited nitric oxide (NO)/inducible nitric oxide synthase (iNOS) in P. gingivalis LPS-activated RAW264.7 cells and pro-inflammatory cytokines (IL-1β and IL-6) and matrix metalloproteinase (MMP-8 and MMP-9) in HGF-1 cells. In addition, LAB treatment inhibited osteoclastogenesis by reducing tartrate-resistant acid phosphatase (TRAP) activity and cathepsin K (CtsK) through the downregulation of nuclear factor of activated T cells cytoplasmic 1 (NFATc1) and c-fos gene expression in RANKL-induced RAW264.7 cells. Administration of MG4706 alleviated alveolar bone loss indices and reduced the gene expression of IL-1β, IL-6, MMP-8, MMP-9, and RANKL/OPG ratio in gingival tissue. In conclusion, L. rhamnosus MG4706 has the potential to alleviate periodontitis.

Abstract
Pathogenic variants of the gene Eda cause X-linked hypohidrotic ectodermal dysplasia (XLHED), which is characterized by structural abnormalities or lack of ectodermal appendages. Signs of dysplasia are not restricted to derivatives of the ectodermal layer, but mesodermal abnormalities, such as craniofacial dysmorphism, are also frequently observed, suggesting close reciprocal interactions between the ectoderm and mesoderm; however, a causal link has remained unsubstantiated. We investigated the functional impact of defective ectodysplasin A1 (Eda1) signaling on postnatal bone homeostasis in Eda1-deficient Tabby mice. Interestingly, Eda1 was detected in wild-type mouse calvariae throughout postnatal lifetime. In calvariae, bone-lining Osterix (Osx)+ osteoblasts stained positive for Eda1, and osteoclasts were revealed as Eda receptor (Edar)-positive. Moreover, adult Eda1-deficient calvarial bone showed osteopetrosis-like changes with significantly diminished marrow space, which was maintained during adulthood. Concomitantly with osteopetrosis-like changes, Tabby calvarial bone and Tabby bone marrow-derived osteoclasts had far less osteoclastic activity-associated co-enzymes including cathepsin K, Mmp9, Trap, and Tcirg1 (V-type proton ATPase a3 subunit) compared with wild-type calvariae in vivo or osteoclasts in vitro, indicating that Eda1 deficiency may affect the activity of osteoclasts. Finally, we confirmed that nuclear Nfatc1-positive osteoclasts were strongly diminished during mature osteoclastic differentiation under M-CSF and RANKL in the Tabby model, while Fc-EDA treatment of Tabby-derived osteoclasts significantly increased nuclear translocation of Nfatc1. Furthermore, we identified enhanced Nfatc1 and NF-κB transcriptional activity following Fc-EDA treatment in vitro using luciferase assays. Overall, the results indicate that diminished expressions of osteoclastic activity-associated co-enzymes may lead to disturbed bone homeostasis in Tabby calvariae postnatally.

Abstract
The gaps between the complex nature of cancer and therapeutics have been narrowed down due to extensive research in molecular oncology. Despite gathering massive insight into the mysteries of tumor heterogeneity and the molecular framework of tumor cells, therapy resistance and adverse side effects of current therapeutic remain the major challenge. This has shifted the attention towards therapeutics with less toxicity and high efficacy. Myricetin a natural flavonoid has been under the spotlight for its anti-cancer, anti-oxidant, and anti-inflammatory properties. The cutting-edge molecular techniques have shed light on the interplay between myricetin and dysregulated signaling cascades in cancer progression, invasion, and metastasis. However, there are limited data available regarding the nano-delivery platforms composed of myricetin in cancer. In this review, we have provided a comprehensive detail of myricetin-mediated regulation of different cellular pathways, its implications in cancer prevention, preclinical and clinical trials, and its current available nano-formulations for the treatment of various cancers.

Abstract
Bone-destructive diseases, caused by overdifferentiation of osteoclasts, reduce bone mass and quality, and disrupt bone microstructure, thereby causes osteoporosis, Paget's disease, osteolytic bone metastases, and rheumatoid arthritis. Osteoclasts, the only multinucleated cells with bone resorption function, are derived from haematopoietic progenitors of the monocyte/macrophage lineage. The regulation of osteoclast differentiation is considered an effective target for the treatment of bone-destructive diseases. Natural plant-derived products have received increasing attention in recent years due to their good safety profile, the preference of natural compounds over synthetic drugs, and their potential therapeutic and preventive activity against osteoclast-mediated bone-destructive diseases. In this study, we reviewed the research progress of the potential antiosteoclast active compounds extracted from medicinal plants and their molecular mechanisms. Active compounds from natural plants that inhibit osteoclast differentiation and functions include flavonoids, terpenoids, quinones, glucosides, polyphenols, alkaloids, coumarins, lignans, and limonoids. They inhibit bone destruction by downregulating the expression of osteoclast-specific marker genes (CTSK, MMP-9, TRAP, OSCAR, DC-STAMP, V-ATPase d2, and integrin av3) and transcription factors (c-Fos, NFATc1, and c-Src), prevent the effects of local factors (ROS, LPS, and NO), and suppress the activation of various signalling pathways (MAPK, NF-κB, Akt, and Ca2+). Therefore, osteoclast-targeting natural products are of great value in the prevention and treatment of bone destructive diseases.

Abstract
Flavonoids are polyphenolic compounds spotted in various fruits, vegetables, barks, tea plants, and stems and many more natural commodities. They have a multitude of applications through their anti-inflammatory, anti-oxidative, anti-carcinogenic properties, along with the ability to assist in the stimulation of bone formation. Bone, a rigid connective body tissue made up of cells embedded in a mineralised matrix is maintained by an assemblage of pathways assisting osteoblastogenesis and osteoclastogenesis. These have a significant impact on a plethora of bone diseases. The homeostasis between osteoblast and osteoclast formation decides the integrity and structure of the bone. The flavonoids discussed here are quercetin, kaempferol, icariin, myricetin, naringin, daidzein, luteolin, genistein, hesperidin, apigenin and several other flavonoids. The effects these flavonoids have on the mitogen activated protein kinase (MAPK), nuclear factor kappa β (NF-kβ), Wnt/β-catenin and bone morphogenetic protein 2/SMAD (BMP2/SMAD) signalling pathways, and apoptotic pathways lead to impacts on bone remodelling. In addition, these polyphenols regulate angiogenesis, decrease the levels of inflammatory cytokines and play a crucial role in scavenging reactive oxygen species (ROS). Considering these important effects of flavonoids, they may be regarded as a promising agent in treating bone-related ailments in the future.

Abstract
The purpose of the present study was to investigate the pharmacological effect of Fisetin on experimental periodontitis in rats and explore its potential mechanism. The ligature/LPS method was used to induce periodontitis in rats. LPS was employed to cause inflammation in Human gingival fibroblasts (HGF). The transfections with FGFR1 SiRNA, NLRP3 SiRNA and the selective TLR4 inhibitor TAK242 were used to investigate the mechanism of Fisetin-mediated inflammatory reaction in LPS-induced HGF. As a result, Fisetin reduced the alveolar bone gap, reversed histopathological lesion and inhibited serum inflammatory cytokine concentration in periodontitis rats. Fisetin decreased the inflammatory cytokine contents in the supernatant of LPS-induced HGF. The inhibitory effect of Fisetin might be attributed to FGFR1/TLR4/NLRP3 inflammasome pathway both in vivo and in vitro. The suppressions of FGFR1, TLR4 and NLRP3 proved that FGFR1/TLR4/NLRP3 signaling was involved in the Fisetin-mediated inflammatory response. Fisetin also inhibited NLRP3 priming. The data demonstrated that Fisetin attenuated periodontitis by inhibiting inflammatory reaction via FGFR1/TLR4/NLRP3 inflammasome pathway.

Abstract
Background:
Matrix metalloproteinase-8 (MMP-8) participates in the degradation of different
types of collagens in the extracellular matrix and basement membrane. Up-regulation of the
MMP-8 has been demonstrated in many disorders including cancer development, tooth caries, periodontal/
peri-implant soft and hard tissue degeneration, and acute/chronic inflammation. Therefore,
MMP-8 has become an encouraging target for therapeutic procedures for scientists. We carried out a
molecular docking approach to study the binding affinity of 29 flavonoids, as drug candidates, with
the MMP-8. Pharmacokinetic and toxicological properties of the compounds were also studied.
Moreover, it was attempted to identify the most important amino acids participating in ligand binding
based on the degree of each of the amino acids in the ligand-amino acid interaction network for
MMP-8.
Methods:
Three-dimensional structure of the protein was gained from the RCSB database (PDB ID: 4QKZ).
AutoDock version 4.0 and Cytoscape 3.7.2 were used for molecular docking and network analysis,
respectively. Notably, the inhibitor of the protein in the crystalline structure of the 4QKZ was considered
as a control test. Pharmacokinetic and toxicological features of compounds were predicted
using bioinformatics web tools. Post-docking analyses were performed using BIOVIA Discovery
Studio Visualizer version 19.1.0.18287.
Results and Discussions:
According to results, 24 of the studied compounds were considered to be
top potential inhibitors for MMP-8 based on their salient estimated free energy of binding and inhibition
constant as compared with the control test: Apigenin-7-glucoside, nicotiflorin, luteolin,
glabridin, taxifolin, apigenin, licochalcone A, quercetin, isorhamnetin, myricetin, herbacetin,
kaemferol, epicatechin, chrysin, amentoflavone, rutin, orientin, epiafzelechin, quercetin-3-
rhamnoside, formononetin, isoliquiritigenin, vitexin, catechine, and isoquercitrin. Moreover, His-
197 was found to be the most important amino acid involved in the ligand binding for the enzyme.
Conclusion:
The results of the current study could be used in the prevention and therapeutic procedures
of a number of disorders such as cancer progression and invasion, oral diseases, and
acute/chronic inflammation. Although, in vitro and in vivo tests are inevitable in the future.

Abstract
The interaction between alveolar epithelial cells (EpCs) and macrophages (MPs) serves an important role in initiating and maintaining inflammation in chronic pulmonary diseases. The aim of the present study was to investigate the molecular mechanisms of the inflammatory response in co-cultured EpCs and MPs. Briefly, a co-culture system of A549 (EpCs) and THP-1 (monocyte/MPs) cells was established in a filter-separated Transwell plate to evaluate the inflammatory response. Following lipopolysaccharide (LPS) treatment, cytokine levels were measured using ELISAs, NF-κB transcription factor activity was detected using EMSA and protein expression levels were analyzed using Western blot assays subsequently in EpCs and MPs. Co-cultured EpCs/MPs were found to secrete increased levels of interleukin (IL)-6, IL-1β, IL-8 and tumor necrosis factor (TNF)-α following LPS exposure for 6, 12, 24 and 48 h compared with either EpC or MP monocultures. Concurrently, NF-κB was revealed to be activated in MPs at 6 and 12 h, and in EpCs at 24 h. NF-κB DNA binding, Toll-like receptor 4 expression levels and the p65 phosphorylation status were also increased, which may contribute to the inflammatory response in the EpC/MP co-cultures. Notably, cytokine levels decreased following the inhibition of NF-κB expression with pyrrolidinedithiocarbamate. In conclusion, the present study successfully established an EpC/MP co-culture system using LPS, which may be a useful model for studying chronic inflammation in vitro.

Abstract
The TCIRG1 gene encodes the a3 isoform of vacuolar H+-ATPase (V-ATPase), which forms a proton transport channel in osteoclasts. Defects in this gene lead to functional impairment of osteoclasts and increased bone mass; however, the molecular mechanisms of TCIRG1 loss have not been fully elucidated. In the current study, we transfected mouse bone marrow-derived monocytes with control or Tcirg1-knockdown lentiviruses to further investigate the mechanisms of TCIRG1. Our results demonstrate that knockdown of Tcirg1 inhibits large-osteoclast (>100 μm) generation by decreasing the expression of nuclear factor of activated T-cells 1 (NFATc1) and inositol-1,4,5-trisphosphate receptor 2 (IP3R2). The decreased IP3R2 reduces intracellular calcium levels, which limits the nuclear translocation of NFATc1 in RANKL-induced mouse bone marrow-derived monocytes. These findings provide a mechanism to explain the effects of TCIRG1 impairment, with potential implications for the development of therapies for osteopetrosis.

Abstract
Excessive numbers of osteoclasts are responsible for inflammation-induced osteolysis. Identification of osteoclast-targeting agents may facilitate the development of a novel therapeutic approach for the treatment of pathological bone loss. Seven-amino acid truncated (7ND) protein, a mutant form of monocyte chemoattractant protein-1 (MCP-1), functions as a competitive inhibitor of MCP-1. However, the effects of 7ND protein on osteoclast differentiation remain unknown. Therefore, in the present study, the effects of 7ND protein on osteoclast differentiation induced by tumour necrosis factor superfamily member 11 were investigated. In the present study, 7ND protein inhibited the osteoclast differentiation of peripheral blood mononuclear cells without influencing cell proliferation. Furthermore, to evaluate the effects of 7ND protein in vivo, a lipopolysaccharide (LPS)-induced calvarial bone erosion animal model was established. The 7ND protein remarkably attenuated LPS-induced bone resorption, as assessed by micro-computed tomography and histological analysis. Taken together, the present results suggested the feasibility of local delivery of 7ND protein to mitigate osteoclast differentiation and LPS-induced osteolysis, which may represent a potential approach to treat inflammatory bone destruction.

Abstract
BACKGROUND Heat stroke-induced mortality is rising across the globe. So, the design of prophylactic and/or therapeutic modalities for heat stroke is pressing need. The common plant derived flavonoid exhibits strong anti-oxidant and anti-inflammatory activities; however, its effects in heat stroke remain unknown. The study aimed to investigate the cardioprotective effects of myricetin on heat stroke induced acute myocardial injury as well as lethality in rats and to explore the underlying mechanisms. METHODS Myocardial injury was induced by subjecting the anesthetized rats to a high ambient temperature of 43 °C for 70 min. An intragastrical dose of myricetin (5-25 mg/kg body weight) was given to rats once per day for one week prior to the start of heat stress. Heat shock protein 72 antibodies was given intraperitoneally to rats 24 h before the start of heat stress. Myocardial injury severity was estimated by determing myocardial damage scores, myocardial injury indicators, myocardial oxidative and inflammatory factors. Western blot analysis was used for cardiac expression of heat shock protein (HSP)72. RESULTS Significant (P < 0.05) up-regulation of HSP-72 after chronic administration of myricetin coincided with significant (P < 0.05) reduction in hyperthermia, hypotension, cardiac inflammatory and oxidative damage and lethality. Inhibition of HSP-72 showed a significant (P < 0.05) reversal in the cardiaprotection as well as survival. CONCLUSIONS Our results indicate that myricetin diminishes myocardial injury as well as lethality in heat stroke by up-regulating HSP-72 and show promise as a novel prevention therapeutic for heat stroke.

Abstract
Despite the response to the receptor activator of nuclear factor κ-Β ligand (RANKL), a study has reported that lipopolysaccharide (LPS) could induce RAW264.7 linage osteoclastic differentiation. However, on the contrary, another study recently showed that the LPS-induced multinuclear cells from RAW264.7 did not express osteoclastic functions. Interestingly, in our previous study, we found that RAW264.7 cells pretreated with 10 ng LPS plus macrophage-colony stimulating factor did not show any effects for enhancing RANKL-induced osteoclastic cell differentiation. Therefore, in our current study, we aim to investigate the oteoclastogesis induction ability and efficacy of LPS in the RAW264.7 cell line and relevant molecular signaling. The osteoclastogenic activity of LPS-treated RAW264.7 linage was studied by bone resorption pits and fibrous actin study. Besides that, through polymerase chain reaction and western blot, we showed that the transcriptional factor c-Fos and Nfatc1 might be associated with LPS-induced osteoclastogenesis. Overall, the results of our current study showed positive proof for osteoclast generation from LPS-independent treatment, as well as established an optimal and efficient method for this process.

Abstract
1. This study determined the effects of (E)-3-(2-(4-(3-(2,4-dimethoxyphenyl)acryloyl)phenoxy)ethoxy)-5,7-dimethoxy-2-(3,4,5-trimethoxyphenyl)-4H-chromen-4-one (EDACO) on the differentiation of Gaoyou duck embryonic osteoclasts cultured in vitro. 2. Bone marrow mononuclear cells (BM-MNC) were collected from 23-d-old Gaoyou duck embryos and induced by macrophage colony-stimulating factor and receptor activator of nuclear factor κB ligand in the presence of EDACO at different concentrations (i.e. 10, 20, 40, 80 and 160 µM). Tartrate-resistant acid phosphatase (TRAP) staining and resorption ability determination were conducted. 3. Results suggested that EDACO suppressed the shaping of positive multinucleated cells and the number of TRAP-positive cells in the 20, 40, 80 and 160 μM EDACO groups was significantly decreased (P < 0.05 or P < 0.01). Besides, the absorption activity of differentiated duck embryonic osteoclasts was significantly inhibited (P < 0.05) in both 80 and 160 μM EDACO groups. 4. Overall, EDACO can inhibit the differentiation of BM-MNC into mature osteoclasts in duck embryos.1.

Abstract
A number of polyphenolic compounds present in fruits and vegetables have the capacity to modulate immune responses; however, the impact of the common plant-derived flavonoid myricetin on T lymphocyte function has not been investigated. We show that myricetin inhibited mouse T lymphocyte activation by bead-immobilized anti-CD3 and anti-CD28 monoclonal antibodies, as indicated by a dose-dependent reduction in cell proliferation and decreased synthesis of interferon-γ, interleukin (IL)-2, IL-4, and IL-17 associated with different T helper cell subsets. This effect was attributed to myricetin-induced reactive oxygen species (ROS) since myricetin caused hydrogen peroxide (H2 O2 ) to accumulate in cell-free culture medium and H2 O2 inhibited T cell proliferation and cytokine synthesis. In addition, the antioxidant N-acetyl cysteine restored the ability of myricetin-treated T lymphocytes to proliferate in response to a mitogenic stimulus. The presence of dendritic cells or bone marrow-derived macrophages negated the inhibitory effect of myricetin on T cell activation, and H2 O2 in T cell cultures that were treated with exogenous H2 O2 was reduced when antigen-presenting cells were also present. These findings suggest that antioxidant molecules produced by dendritic cells and macrophages protected T cells from myricetin-induced oxidative stress, and underscore the importance of considering immune cell interactions when evaluating the immunomodulatory activity of ROS-generating phytochemicals.

Abstract
Tumour metastasis is the major cause of breast cancer mortality. Myricetin, a natural polyphenol, is found in teas, wines, and berries. The pharmacodynamic action and molecular mechanism of myricetin on breast cancer metastasis remain unknown. Here, we investigated the effect of myricetin on MDA-Mb-231Br cell viability, migration, invasion, and 4T1 mouse lung metastasis mouse models. MMP-2/9 protein expression and ST6GALNAC5 expression were analysed using western blot assays and quantitative real-time polymerase chain reaction, respectively. Cell migration and invasion were detected by wound-healing and Boyden transwell assays. The antimetastatic effect in vivo was evaluated by lung metastasis model. Myricetin significantly decreased the activities of MMP-2/9 and mRNA levels of ST6GALNAC5. In addition, the migration, invasion, and adhesion were effectively inhibited in a concentration-dependent manner. On the other hand, mice treated with myricetin exhibited smaller tumour nodules compared with the vehicle mice, with only 17.78 ± 15.41% after treatment with 50 mg/kg myricetin. In conclusion, myricetin could significantly block invasion of MDA-Mb-231Br cells through suppressing the protein expression of MMP-2/9 and the expression of ST6GALNAC5, as well as lung metastasis in a mouse model, which suggests that myricetin should be developed as a potential therapeutic candidate for breast cancer.

Abstract
OBJECTIVES Hypoxia-inducible factor-1α (HIF-1α) has been implicated in periodontal tissue inflammation and possibly in osteoclast differentiation, while polyphenols are known to be anti-inflammatory natural compounds that are capable of regulating the NF-κB protein complex pathway. The objective of this study was to investigate cytotoxicity and HIF-1α expression through the NF-κB pathway by polyphenol velutin (Euterpe oleracea Mart.), found in the pulp of acai fruit, during inflammatory RAW 264.7 differentiation. DESIGN RAW 264.7 mouse monocyte macrophage cells were stimulated with RANKL (30ng/mL) and Porphyromonas gingivalis lipopolysaccharide (1μg/mL). Cells were treated with various concentrations of velutin (0.5-2μM) to check for viability, morphology, osteoclast differentiation, and HIF-1α expression (Western blot). RESULTS Alamar blue cell viability assay showed no toxicity to RAW cells with the use of velutin in all concentrations tested (p>0.05). Velutin did not induce cell apoptosis based on caspase 3/7 assay (p>0.05). Fluorescence images stained by DAPI showed no alteration in the morphology of RAW cell nuclei (p>0.05) treated with velutin. TRAP assays demonstrated a dose-dependent reduction in osteoclast formation by velutin when compared with control (p<0.05). Velutin showed a reduction in HIF-1α expression related to IκB phosphorylation when compared with control (p<0.001). CONCLUSIONS At the tested concentrations, velutin was not cytotoxic to RAW 264.7 and differentiated cells. Velutin reduced osteoclast differentiation and downregulated HIF-1α through the NF-κB pathway.

Abstract
For millennia, in the different cultures all over the world, plants have been extensively used as a source of therapeutic agents with wide-ranging medicinal applications, thus becoming part of a rational clinical and pharmacological investigation over the years. As bioactive molecules, plant-derived polyphenols have been demonstrated to exert many effects on human health by acting on different biological systems, thus their therapeutic potential would represent a novel approach on which natural product-based drug discovery and development could be based in the future. Many reports have provided evidence for the benefits derived from the dietary supplementation of polyphenols in the prevention and treatment of osteoporosis. Polyphenols are able to protect the bone, thanks to their antioxidant properties, as well as their anti-inflammatory actions by involving diverse signaling pathways, thus leading to bone anabolic effects and decreased bone resorption. This review is meant to summarize the research works performed so far, by elucidating the molecular mechanisms of action of polyphenols in a bone regeneration context, aiming at a better understanding of a possible application in the development of medical devices for bone tissue regeneration.

Abstract
BACKGROUND Sepsis-induced cardiomyopathy is a well-known cause of mortality. Recent evidence has highlighted the important role of myricetin in anti-inflammation and anti-oxidative stress. However, little is known about its effect on endotoxin-induced cardiomyopathy. We examined the effect of myricetin on lipopolysaccharide (LPS)-induced cardiomyocyte injury and the underlying mechanisms in vitro. METHODS mRNA expression of interleukin (IL)-1beta, IL-6, and tumor necrosis factor (TNF)-alpha was examined via reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Protein expression levels of NF-κB/p65, IκB, IL-1beta, IL-6, and TNF-alpha were assesses via Western blotting. Immunofluorescence (IF) was used to determine the nuclear translocation of p65. Commercial kits were employed to detect the level of oxidative markers and to quantify NF-κB/p65 both in the cytoplasm and the nucleus. Finally, terminal deoxy-nucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) was performed to evaluate the apoptosis of H9c2 cardiomyocytes. RESULTS The results showed that myricetin blunted the overexpression of IL-1beta, IL-6, and TNF-alpha markedly by inhibiting the NF-κB/P65 signaling pathway. Furthermore, myricetin treatment led to the downregulation of reactive oxygen species (ROS) accompanied by increased expression of superoxide dismutase and glutathione peroxidase. TUNEL-positive nuclei were rarely detected following myricetin treatment. CONCLUSION Our findings suggest that myricetin is a valuable protective agent against endotoxin-induced early inflammatory responses in H9c2 cardiomyocytes, which involves regulation of ROS and the IκB/NF-κb signaling pathway.

Abstract
Epigenetic modulation of gene expression has drawn enormous attention among researchers globally in the present scenario. Since their discovery, Jmj-C histone demethylases were identified as useful markers in understanding the role of epigenetics in inflammatory conditions and in cancer as well. This has created arousal of interest in search of suitable candidates. Potential inhibitors from various other scaffolds such as hydroxyquinolines, hydroxamic acids and triazolopyridines have already been identified and reported. In this direction, our present study attempts to target one of the important members of the family- namely JMJD3 (also known as KDM6B), that plays a pivotal role in inflammatory and immune reactions. Using molecular modeling approaches, myricetin analogues were identified as promising inhibitors of JMJD3. Extensive literature review showed myricetin as the most promising flavonol inhibitor for this enzyme. It served as a prototype for our study and modification of it's scaffold led to generation of analogues. The ZINC database was used as a repository for natural compounds and their analogues. Using similarity search options, 65 analogues of myricetin were identified and screened against JMJD3 (PDB ID: 4ASK), using the high throughput virtual screening and ligand docking tools in Maestro Molecular Modeling platform (version 10.5) from Schrödinger, LLC. 8 analogues out of 65 were identified as the most appropriate candidates which gave the best pose in ligand docking. Their binding mode and energy calculations were analysed using induced fit docking (IFD) and prime-MMGBSA tool, respectively. Thus, our findings highlight the most promising analogues of myricetin with comparable binding affinity as well as binding energy than their counterparts that could be taken for further optimisation as inhibitors of JMJD3 in both in vitro and in vivo screening studies.

Abstract
Matrix metalloproteinases (MMPs) are endopeptidases responsible for the hydrolysis of various components of extracellular matrix. MMPs, namely gelatinases MMP-2 and MMP-9, contribute to the progression of chronic and degenerative diseases. Since gelatinases' activity and expression are regulated by oxidative stress, we sought to evaluate whether supplementation with polyphenol-rich red grape skin extracts modulated the matrix-degrading capacity in cell models of vascular inflammation. Human endothelial and monocytic cells were incubated with increasing concentrations (0.5-25 μg/mL) of Negroamaro and Primitivo red grape skin polyphenolic extracts (NSPE and PSPE, respectively) or their specific components (0.5-25 μmol/L), before stimulation with inflammatory challenge. NSPE and PSPE inhibited, in a concentration-dependent manner, endothelial invasion as well as the MMP-9 and MMP-2 release in stimulated endothelial cells, and MMP-9 production in inflamed monocytes, without affecting tissue inhibitor of metalloproteinases (TIMP)-1 and TIMP-2. The matrix degrading inhibitory capacity was the same for both NSPE and PSPE, despite their different polyphenolic profiles. Among the main polyphenols of grape skin extracts, trans-resveratrol, trans-piceid, kaempferol and quercetin exhibited the most significant inhibitory effects on matrix-degrading enzyme activities. Our findings appreciate the grape skins as rich source of polyphenols able to prevent the dysregulation of vascular remodelling affecting degenerative and inflammatory diseases.

Abstract
Excessive bone resorption plays a central role on the development of bone erosive diseases, including osteoporosis, rheumatoid arthritis, and periodontitis. Osteoclasts, bone-resorbing multinucleated cells, are differentiated from hemopoietic progenitors of the monocyte/macrophage lineage. Regulation of osteoclast differentiation is considered an effective therapeutic target to the treatment of pathological bone loss. Natural plant-derived products, with potential therapeutic and preventive activities against bone-lytic diseases, have received increasing attention in recent years because of their whole regulative effects and specific pharmacological activities, which are more suitable for long-term use than chemically synthesized medicines. In this review, we summarized the detailed research progress on the active compounds derived from medical plants with potential anti-resorptive effects and their molecular mechanisms on inhibiting osteoclast formation and function. The active ingredients derived from natural plants that are efficacious in suppressing osteoclastogenesis and bone resorption include flavonoids, terpenoids (sesquiterpenoids, diterpenoids, triterpenoids), glycosides, lignans, coumarins, alkaloids, polyphenols, limonoids, quinones and others (steroid, oxoxishhone, fatty acid). Studies have shown that above natural products exert the inhibitory effects via regulating many factors involved in the process of osteoclast differentiation and bone resorption, including the essential cytokines (RANKL, M-CSF), transcription factors (NFATc1, c-Fos), signaling pathways (NF-κB, MAPKs, Src/PI3K/Akt, the calcium ion signaling), osteoclast-specific genes (TRAP, CTSK, MMP-9, integrin β3, OSCAR, DC-STAMP, Atp6v0d2) and local factors (ROS, LPS, NO). The development of osteoclast-targeting natural products is of great value for the prevention or treatment of bone diseases and for bone regenerative medicine.

Huang J, Wu C, Tian B, Zhou X, Ma N, Qian Y. Myricetin Prevents Alveolar Bone Loss in an Experimental Ovariectomized Mouse Model of Periodontitis. Int J Mol Sci 2016; 17:422. [PMID: 27011174 PMCID: PMC4813273 DOI: 10.3390/ijms17030422] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2016] [Revised: 03/10/2016] [Accepted: 03/15/2016] [Indexed: 12/11/2022] Open
Abstract
Periodontitis is a common chronic inflammatory disease, which leads to alveolar bone resorption. Healthy and functional alveolar bone, which can support the teeth and enable their movement, is very important for orthodontic treatment. Myricetin inhibited osteoclastogenesis by suppressing the expression of some genes, signaling pathways, and cytokines. This study aimed to investigate the effects of myricetin on alveolar bone loss in an ovariectomized (OVX) mouse model of periodontitis as well as in vitro osteoclast formation and bone resorption. Twenty-four healthy eight-week-old C57BL/J6 female mice were assigned randomly to four groups: phosphate-buffered saline (PBS) control (sham) OVX + ligature + PBS (vehicle), and OVX + ligature + low or high (2 or 5 mg∙kg−1∙day−1, respectively) doses of myricetin. Myricetin or PBS was injected intraperitoneally (i.p.) every other day for 30 days. The maxillae were collected and subjected to further examination, including micro-computed tomography (micro-CT), hematoxylin and eosin (H&E) staining, and tartrate-resistant acid phosphatase (TRAP) staining; a resorption pit assay was also performed in vitro to evaluate the effects of myricetin on receptor activator of nuclear factor κ-B ligand (RANKL)-induced osteoclastogenesis. Myricetin, at both high and low doses, prevented alveolar bone resorption and increased alveolar crest height in the mouse model and inhibited osteoclast formation and bone resorption in vitro. However, myricetin was more effective at high dose than at low dose. Our study demonstrated that myricetin had a positive effect on alveolar bone resorption in an OVX mouse model of periodontitis and, therefore, may be a potential agent for the treatment of periodontitis and osteoporosis.

Abstract
Myricetin is a common plant-derived flavonoid and is well recognised for its nutraceuticals value. It is one of the key ingredients of various foods and beverages. The compound exhibits a wide range of activities that include strong anti-oxidant, anticancer, antidiabetic and anti-inflammatory activities. It displays several activities that are related to the central nervous system and numerous studies have suggested that the compound may be beneficial to protect against diseases such as Parkinson's and Alzheimer's. The use of myricetin as a preserving agent to extend the shelf life of foods containing oils and fats is attributed to the compound's ability to protect lipids against oxidation. A detailed search of existing literature revealed that there is currently no comprehensive review available on this important molecule. Hence, the present work includes the history, synthesis, pharmaceutical applications and toxicity studies of myricetin. This report also highlights structure-activity relationships and mechanisms of action for various biological activities.

Abstract
Allium cepa L. is known to possess numerous pharmacological properties. Our aim was to examine the in vitro effects of Allium cepa L. extract (AcE) on Porphyromonas gingivalis LPS and Escherichia coli LPS-stimulated osteoclast precursor cells to determine cell viability to other future cell-based assays. Osteoclast precursor cells (RAW 264.7) were stimulated by Pg LPS (1 μg/mL) and E. coli LPS (1 μg/mL) in the presence or absence of different concentrations of AcE (10-1000 μg/mL) for 5 days at 37°C/5% CO2. Resazurin reduction and total protein content assays were used to detect cell viability. AcE did not affect cell viability. Resazurin reduction assay showed that AcE, at up to 1000 μg/mL, did not significantly affect cell viability and cellular protein levels. Additionally a caspase 3/7 luminescence assay was used to disclose apoptosis and there was no difference in apoptotic activity between tested groups and control group. Fluorescence images stained by DAPI showed no alteration on the morphology and cell counts of LPS-stimulated osteoclast precursor cells with the use of AcE in all tested concentrations when compared to control. These findings suggest that Allium cepa L. extract could be used for in vitro studies on Porphyromonas gingivalis LPS and Escherichia coli LPS-stimulated osteoclast precursor cells.

Abstract
BACKGROUND/OBJECTIVES Obesity-associated insulin resistance is a strong risk factor for type 2 diabetes mellitus. The aim of this study was to investigate the effect of myricetin on adiposity, insulin resistance, and inflammatory markers in mice with diet-induced insulin resistance. MATERIALS/METHODS Five-week-old male C57BL/6J mice were fed a basal diet, a high-fat, high-sucrose (HFHS) diet, or the HFHS diet containing 0.06% myricetin or 0.12% myricetin for 12 weeks after a 1-week adaptation, and body weight and food intake were monitored. After sacrifice, serum lipid profiles, glucose, insulin, adipocyte-derived hormones, and proinflammatory cytokines were measured. The homeostasis model assessment for insulin resistance (HOMA-IR) was determined. RESULTS Myricetin given at 0.12% of the total diet significantly reduced body weight, weight gain, and epidydimal white adipose tissue weight, and improved hypertriglyceridemia and hypercholesterolemia without a significant influence on food intake in mice fed the HFHS diet. Serum glucose and insulin levels, as well as HOMA-IR values, decreased significantly by 0.12% myricetin supplementation in mice fed the HFHS diet. Myricetin given at 0.12% of the total diet significantly reduced serum levels of leptin, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in mice fed the HFHS diet. CONCLUSIONS These findings suggest that myricetin may have a protective effect against diet-induced obesity and insulin resistance in mice fed HFHS diet, and that alleviation of insulin resistance could partly occur by improving obesity and reducing serum proinflammatory cytokine levels.

Abstract
Syzygium tetragonum Wall is a Chinese folk medicine for the treatment of rheumatism, joint swelling and pain. By High Content Screening (HCS), 8 compounds (1-8) from Syzygium tetragonum Wall were evaluated for their inhibitory activity on the nuclear translocation of NFATc1 in EGFP-NFATc1 U2OS cells. Among them, 6-[10'(Z)-heptadecenyl] salicylic acid (8) exhibited a significant inhibitory activity. In RAW 264.7 cells, it could dose-dependently prevent nuclear NFATc1 translocation induced by receptor activator of nuclear factor κB ligand (RANKL). The differentiation of osteoclasts from bone marrow derived macrophages (BMMs) was significantly inhibited by 8 in a dose-dependent manner. The mRNA expression of TRAP, CtsK, and MMP9, key enzymes for the bone resorption secreted by osteoclasts, were also significantly down-regulated; and MMP9 activity was also obviously decreased. More importantly, the bone resorption activity of osteoclasts was dose-dependently suppressed by compound 8. Our results suggest that compound 8 can effectively inhibit osteoclastogenesis and bone erosion via preventing NFATc1 nuclear translocation and might be a promising drug candidate for relevant diseases.
