Pharmacological Potential of Kaempferol, a Flavonoid in the Management of Pathogenesis via Modulation of Inflammation and Other Biological Activities. Molecules 2024; 29:2007. [PMID: 38731498 PMCID: PMC11085411 DOI: 10.3390/molecules29092007] [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: 03/11/2024] [Revised: 04/22/2024] [Accepted: 04/23/2024] [Indexed: 05/13/2024] Open
Abstract
Natural products and their bioactive compounds have been used for centuries to prevent and treat numerous diseases. Kaempferol, a flavonoid found in vegetables, fruits, and spices, is recognized for its various beneficial properties, including its antioxidant and anti-inflammatory potential. This molecule has been identified as a potential means of managing different pathogenesis due to its capability to manage various biological activities. Moreover, this compound has a wide range of health-promoting benefits, such as cardioprotective, neuroprotective, hepatoprotective, and anti-diabetic, and has a role in maintaining eye, skin, and respiratory system health. Furthermore, it can also inhibit tumor growth and modulate various cell-signaling pathways. In vivo and in vitro studies have demonstrated that this compound has been shown to increase efficacy when combined with other natural products or drugs. In addition, kaempferol-based nano-formulations are more effective than kaempferol treatment alone. This review aims to provide detailed information about the sources of this compound, its bioavailability, and its role in various pathogenesis. Although there is promising evidence for its ability to manage diseases, it is crucial to conduct further investigations to know its toxicity, safety aspects, and mechanism of action in health management.

Abstract
The aim of this study was to evaluate the effects of Coriandrum sativum L. (CSL) seed extract on gingival levels of antioxidant enzymes, pro-inflammatory cytokines and on alveolar bone and attachment levels after experimental periodontitis induction in rats and compare it with low-dose doxycycline (LDD). Forty adult male Wistar Albino rats were divided randomly into 5 groups as follows: 1 = periodontally healthy (control); 2 = periodontitis; 3 = periodontitis + CSL (32 mg/kg); 4 = periodontitis + CSL (200 mg/kg); and 5 = periodontitis + LDD (6 mg/kg). Gingival superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) levels were evaluated by enzyme-linked immunosorbent assay. The presence of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-1βeta (IL-1β) immunoreactivity was detected immunohistochemically. Alveolar bone area in the furcation space (ABA), alveolar bone loss (ABL), and attachment loss (AL) were evaluated histomorphometrically. The SOD level was lower in group 5 than in groups 2, 3, and 4. The IL-1β level was highest in group 4. The TNF-α level was statistically higher in groups 2 and 4 than in groups 1, 3, and 5. The IL-6 level was highest in group 4. Its level was higher in groups 2 and 3 than in group 5. ABA was less in groups 2, 3, and 4 compared to groups 1 and 5. ABL was less in group 5 than in groups 2, 3, and 4. AL was greater in group 4 than in group 5. The use of 200 mg/kg CSL showed a pro-inflammatory effect and IL-1β and TNF-α levels decreased after 32 mg/kg CSL application in the treatment of periodontitis.

Abstract
OBJECTIVES We investigated the association between dietary flavonoids intake and periodontitis. MATERIALS AND METHODS This cross-sectional study analyzed data from the US National Health and Nutrition Examination Survey 2009-2010 on 3025 participants aged between 30 and 80 years who had full-mouth periodontal examination and dietary flavonoids intake data. This study used periodontal pocket depth (PPD) and clinical attachment loss (CAL) as periodontitis markers. Data were analyzed using multivariate linear regression. RESULTS After adjusting confounders, the middle tertile of total dietary flavonoids was associated with decreased mean PPD (0.06 mm, P = 0.016) and mean CAL (0.13 mm, P = 0.001) and the top tertile of total dietary flavonoids was significantly associated with decreases in mean PPD (0.05 mm, P = 0.029) and mean CAL (0.11 mm, P = 0.010). Both the middle and top tertiles of total flavonoids intake were significantly related with decreased mean CAL in females, those flossing 0 days/week, overweight and non-diabetic population but not in males, smokers, those flossing 1-6 days/week and diabetic population. Higher anthocyanidins, flavones and flavonols intake was significantly associated with decreased mean PPD and mean CAL while higher flavanones intake was only significantly associated with decreased mean CAL. Higher anthocyanidins intake was particularly related with greatest decreases in mean CAL (top tertile: 0.22 mm, middle tertile: 0.17 mm, both P < 0.010). However, no significant associations were found between isoflavones and flavan_3_ols intake and mean CAL. CONCLUSIONS Higher dietary flavonoids intake may be beneficial for periodontal health. CLINICAL RELEVANCE Additional anthocyanidins, flavanones, flavones and flavonols intake was associated with improved periodontal health.

Abstract
Periodontal disease is a chronic disease with a high prevalence, and in order to secure natural materials to prevent oral diseases, new materials that protect periodontal tissue from inflammation are being sought. Genes were identified using real-time quantitative polymerase chain reaction (RT-qPCR), and proteins were confirmed using Western blot. Dichlorodihydrofluorescein diacetate (DCF-DA) analysis was used, and the antibacterial effects were confirmed through Minimum Inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC) analysis. To confirm this effect in vivo, Sprague-Dawley rats, in which periodontitis was induced using ligation or Lipopolysaccharide of Porphyromonas gingivalis (PG-LPS), were used. In vitro experiments using human periodontal ligament (HPDL) cells stimulated with PG-LPS showed that Ginsenoside Rg6 (G-Rg6) had anti-inflammatory, antibacterial, antioxidant, and osteoblast differentiation properties. In vivo, G-Rg6 was effective in Sprague-Dawley rats in which periodontitis was induced using ligation or PG-LPS. Therefore, Ginsenoside Rg6 shows potential effectiveness in alleviating periodontitis.

Abstract
(1) To examine the potential mechanism of the Asarum-Angelica drug pair against periodontitis and provide an experimental basis for the treatment of periodontitis with herbal medicine. (2) The core components and core targets of the Asarum-Angelica drug pair in the treatment of periodontitis were detected according to network pharmacology methods. Finally, the effect of the Asarum-Angelica drug pair on osteogenic differentiation was observed in mouse embryonic osteoblast precursor cells. (3) According to the results of network pharmacology, there are 10 potential active ingredients in the Asarum-Angelica drug pair, and 44 potential targets were obtained by mapping the targets with periodontitis treatment. Ten potential active ingredients, such as kaempferol and β-sitosterol, may play a role in treating periodontitis. Cell experiments showed that the Asarum-Angelica drug pair can effectively promote the expression of osteoblast markers alkaline phosphatase (ALP), Runt-related Transcription Factor 2 (RUNX2), and BCL2 mRNA and protein in an inflammatory environment (p < 0.05). (4) Network pharmacology effectively analyzed the molecular mechanism of Asarum-Angelica in the treatment of periodontitis, and the Asarum-Angelica drug pair can promote the differentiation of osteoblasts.

Abstract
Periodontitis, a disease caused by inflammation of oral bacteria, contributes to the loss of alveolar bone and destruction of connective tissues. Porphyromonas gingivalis, a Gram-negative bacterium, is known to possess important pathogenic factors for periodontal disease. In this study, we investigated the anti-periodontitis effects of Magnolia kobus extract (MKE) and magnolin as a component of Magnolia kobus (MK) in murine macrophage RAW 264.7 cells stimulated with Porphyromonas gingivalis lipopolysaccharide (LPS). Effects of MKE and magnolin on the mechanism of RAW 264.7 cellular inflammation were determined by analyzing nitric oxide (NO) production and Western blot protein expression (n = 3). MKE/magnolin inhibited NO production without affecting cell survival. MKE/magnolin treatment inhibited LPS-induced pro-inflammatory cytokines, expression levels of matrix metalloproteinases (MMPs such as MMP-1, 3, 8, 9, and 13), and protein levels of inflammatory mediators (such as TNF-α, IL-1β, and mPGES-1). MKE/magnolin also suppressed NF-κB activation by inhibiting the TLR4 signaling pathway. These findings suggest that MKE has a therapeutic effect on inflammatory periodontal disease caused by oral bacterium P. gingivalis and that magnolin is a major functional component in the anti-inflammatory effect of MKE.

Abstract
Periodontitis is a common oral disease mainly caused by bacterial infection and inflammation of the gingiva. In the prevention or treatment of periodontitis, anti-bacterial agents are used to inhibit pathogen growth, despite increasing levels of bacterial resistance. Sapindus mukorossi Gaertn (SM) seed oil has proven anti-bacterial and anti-inflammation properties. However, the possibility of using this plant to prevent or treat periodontitis has not been reported previously. The aim of this study was to evaluate the effects of SM oil on experimental periodontitis in rats by using micro-CT and microbiota analysis. The distance between cementoenamel junction (CEJ) and alveolar bone crest (ABC) on the sagittal micro-CT slide showed that total bone loss (TBL) was significantly lower in CEJ-ABC distances between SM oil and SM oil-free groups on Day 14. Histology data also showed less alveolar bone resorption, a result consistent result with micro-CT imaging. The microbiota analyzed at phylum and class levels were compared between the SM oil and SM oil-free groups on Day 7 and Day 14. At the phylum level, Proteobacteria, Firmicutes, Bacteroidetes, and Actinobacteria were the dominant bacterium. Firmicutes in box plot analysis was significantly less in the SM oil group than in the SM oil-free group on Day 7. At the class level, Bacteroidia, Gammaproteobacteria, Bacilli, Clostridia, and Erysipelotrichia were the dominant bacteria. The bacteria composition proportion of Bacilli, Clostridiay, and Erysipelotrichia could be seen in the SM oil group significantly less than in t SM oil-free group on Day 7. Overall, the present results show that topical application of SM oil can reduce bone resorption and change bacteria composition in the ligature-induced periodontitis model. According to these results, it is reasonable to suggest SM oil as a potential material for preventing oral disease.

Abstract
Context: Plumeria alba, commonly known as frangipani or West Indian jasmine, is a traditional and ancient folklore medicine known for its antimicrobial, anti-inflammatory, and antioxidant properties. The extracts from P. alba obtained from the leaves, bark, and flowers, are commonly used to manage bacterial, fungal, and viral infections such as herpes, scabies, and fungal infections. The constituents of the P. alba plant have shown promising antihelmintic, antipyretic, and antirheumatic properties. Although studies have confirmed that extracts from Plumeria species are effective against microbial infections and cancer, its role in managing oral diseases, particularly the chronic inflammatory disease of the gums (gingivitis and periodontitis), has never been explored. Therefore, the current study aimed to explore the antimicrobial and cytotoxic properties of the P. alba flower extract against oral and periodontal pathogens compared to chlorhexidine and doxycycline. Settings and Design: This was an in vitro study. Materials and Methods: The ethanolic extract was prepared from the freshly plucked P. alba flowers. The antimicrobial properties of the extract were evaluated by testing the minimal inhibitory concentration, minimal bactericidal concentration, and well-diffusion assay against Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Prevotella intermedia, Tannerella forsythia, Streptococcus mutans, Actinomyces viscosus, Streptococcus salivarius, and Candida albicans. The results were compared to chlorhexidine and doxycycline. The cytotoxicity was checked by the against human-derived gingival fibroblast and keratinocytes. Statistical Analysis Used: One-way ANOVA for the mean zones of inhibition against all the microorganisms was done. Results: P. alba extract inhibited the growth for all the tested oral and periodontal pathogens at 25 μg/ml. The well-diffusion assay of P. alba extract was comparable to chlorhexidine but was not statistically significant compared to doxycycline. Conclusion: P. alba can be used as a promising alternative to chlorhexidine for the management of oral and periodontal infections.

Abstract
BACKGROUND AND PURPOSE Salivary gland damage remains a problem despite advances in radiotherapy schedules for head and neck cancer. Kaempferol, a natural flavonoid, found in several fruits and vegetables, is a good antioxidant. This study was designed to evaluate the possible protective effects of kaempferol on submandibular glands (SMGs) of rats exposed to fractionated gamma irradiation. MATERIALS AND METHODS Twenty-four male adult Wistar albino rats were included in this study and assigned to three groups (n = 8). Rats in group K received kaempferol orally in five doses at a dose of 10 mg/kg/2 days for 10 days. Meanwhile, rats in group R were subjected to fractionated whole-body gamma irradiation at a dose of 2 Gy/5 days/week for 2 weeks (20 Gy), and the KR group received kaempferol as group K and then was subjected to a fractionated whole-body gamma irradiation as group R. SMG samples were collected on days 1 and 7 after the last radiation session; and processed for histopathological and immunohistochemical investigations. RESULTS The SMGs of group R showed focal atrophy and degeneration. Acini showed vacuolization and had pyknotic hyperchromatic nuclei. Striated ducts degenerated, shrunken, and were surrounded by empty spaces. The percentage of areas covered by cyclooxygenase-2 (COX-2) significantly increased, whereas the percentage of areas covered by proliferating cell nuclear antigen (PCNA) significantly decreased compared with those in group K. Cotreatment with kaempferol (group KR) partially preserved normal gland architecture where acinar vacuolation and degeneration were almost absent; however, some ducts degenerated. A significant decrease in the percentage of areas covered by COX-2 and a significant increase in the percentage of areas covered by PCNA were observed compared with those in group R. CONCLUSIONS Kaempferol has a possible radioprotective effect on the SMGs of rats exposed to fractionated gamma irradiation.

[PMID: 35163727 PMCID: PMC8837018 DOI: 10.3390/ijms23031806] [Citation(s) in RCA: 74] [Impact Index Per Article: 37.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Revised: 02/02/2022] [Accepted: 02/03/2022] [Indexed: 02/01/2023] Open
Abstract
Severe periodontitis, a destructive inflammatory disease of the supporting tissues of the teeth, ranks sixth in terms of global spread, affecting about 11% of the population. Metalloproteinases (MMPs) are extracellular matrix (ECM) macromolecules that are important in cellular development and morphogenesis, and they are capable of activating growth factors in their proximity, cell surface receptors, and adhesion molecules. MMPs are part of a major family of zinc-dependent endopeptidases, and their activity is modulated and regulated by certain inhibitors known as tissue metalloproteinase inhibitors (TIMPs). Because type I collagen is the major component of the periodontal extracellular matrix, special attention has been paid to the role of collagenases, especially MMP-8 and MMP-13 and gelatinases, MMP-2 and MMP-9, in periodontal diseases. In fact, MMP-8 (or collagenase 2) is currently one of the most promising biomarkers for periodontitis in oral fluids. Among them, salivary MMP-9 has been shown to be a more sensitive marker for periodontal inflammation during orthodontic treatment, which opens new perspectives in reducing periodontal hazards during such treatments. Both MMP-8 and MMP-9 are extremely valuable diagnostic tools in treating periodontitis, and future studies and healthcare policies should focus on implementing more accessible methods of chairside testing in order to reduce the prevalence of this disease.

Abstract
Bioactive plant derived compounds are important for a wide range of therapeutic applications, and some display promising anticancer properties. Further evidence suggests that phytochemicals modulate autophagy and apoptosis, the two crucial cellular pathways involved in the underlying pathobiology of cancer development and regulation. Pharmacological targeting of autophagy and apoptosis signaling using phytochemicals therefore offers a promising strategy that is complementary to conventional cancer chemotherapy. In this review, we sought to highlight the molecular basis of the autophagic-apoptotic pathway to understand its implication in the pathobiology of cancer, and explore this fundamental cellular process as a druggable anticancer target. We also aimed to present recent advances and address the limitations faced in the therapeutic development of phytochemical-based anticancer drugs.

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
Panax ginseng has a wide range of activities including a neuroprotective effect, skin protective effects, enhanced DNA repairing, anti-diabetic activity, and protective effects against vascular inflammation. In the present study, we sought to discover the inhibitory effects of a mixture of natural products containing Panax ginseng, Ziziphus jujube, Rubi fructus, Artemisiae asiaticae and Scutellaria baicalensis (PZRAS) on osteoclastogenesis and bone remodeling, as neither the effects of a mixture containing Panax ginseng extract, nor its molecular mechanism on bone inflammation, have been clarified yet. PZRAS upregulated the levels of catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GSH-R) and glutathione peroxidase (GSH-Px) and reduced malondialdehyde (MDA) in LPS-treated RAW264.7 cells. Moreover, treatment with PZRAS decreased the production of IL-1β and TNF-α. PZRAS also inhibited osteoclast differentiation through inhibiting osteoclastspecific genes like MMP-2, 9, cathepsin K, and TRAP in RANKL-treated RAW264.7 cells. Additionally, PZRAS has inhibitory functions on the RANKL-stimulated activation of ERK and JNK, which lead to a decrease in the expression of NFATc1 and c-Fos. In an in vivo study, bone resorption induced by LPS was recovered by treatment with PZRAS in bone volume per tissue volume (BV/TV) compared to control. Furthermore, the ratio of eroded bone surface of femurs was significantly increased in LPStreated mice compared to vehicle group, but this ratio was significantly reversed in PZRAS-treated mice. These results suggest that PZRAS could prevent or treat disorders with abnormal bone loss.

Abstract
The control of inflammation and infection is crucial for periodontal wound healing and regeneration. M101, an oxygen carrier derived from Arenicola marina, was tested for its anti-inflammatory and anti-infectious potential based on its anti-oxidative and tissue oxygenation properties. In vitro, no cytotoxicity was observed in oral epithelial cells (EC) treated with M101. M101 (1 g/L) reduced significantly the gene expression of pro-inflammatory markers such as TNF-α, NF-κΒ and RANKL in P. gingivalis-LPS stimulated and P. gingivalis-infected EC. The proteome array revealed significant down-regulation of pro-inflammatory cytokines (IL-1β and IL-8) and chemokine ligands (RANTES and IP-10), and upregulation of pro-healing mediators (PDGF-BB, TGF-β1, IL-10, IL-2, IL-4, IL-11 and IL-15) and, extracellular and immune modulators (TIMP-2, M-CSF and ICAM-1). M101 significantly increased the gene expression of Resolvin-E1 receptor. Furthermore, M101 treatment reduced P. gingivalis biofilm growth over glass surface, observed with live/dead analysis and by decreased P. gingivalis 16 s rRNA expression (51.7%) (p < 0.05). In mice, M101 reduced the clinical abscess size (50.2%) in P. gingivalis-induced calvarial lesion concomitant with a decreased inflammatory score evaluated through histomorphometric analysis, thus, improving soft tissue and bone healing response. Therefore, M101 may be a novel therapeutic agent that could be beneficial in the management of P. gingivalis associated diseases.

Abstract
Background: Vitamin C is an important water-soluble vitamin with antioxidant and immune-modulatory actions. The aim of this study was to investigate the effects of locally applied vitamin C on alveolar bone resorption in rats with experimental periodontitis.Methods: Twenty-one male Sprague-Dawley rats divided into three groups with seven animals in each group: (1) control, (2) experimental periodontitis and 3) experimental periodontitis-local vitamin C treatment group. After ligature was removed, 50 μL vitamin C was locally administered into the subperiosteum of the buccal gingiva of periodontitis vitamin C (PvitC) group rats for three times in intervals of 2 days. At the end of the study, the animals were scarified, and serum and gingival samples were collected for analysis of serum IL-1β, oxidative stress index (OSI), CTX and malondialdehyde (MDA) levels and gingival MMP-8 immunostaining. Alveolar bone loss and attachment loss were determined based on measurements on histological sections obtained from rat mandibles.Results: Serum MDA and OSI levels which are related to the oxidative stress were significantly lower in the PvitC group as compared with those in the P group (p < .05). Serum CTX levels which are related to the bone resorption were significantly lower in the PvitC group as compared with those in the P group (p < .05). The numeric density of MMP-8-positive cells was significantly lower in the PvitC group compared to P group (p < .05). Alveolar bone loss and attachment loss were significantly lower in the PvitC group compared to P group (p < .05)Conclusions: The local vitamin C administration provided protection against inflammation-induced alveolar bone resorption by decreasing oxidative stress and inflammation-induced tissue breakdown vitamin C may be a therapeutic agent that can be used in periodontitis treatment.

Abstract
Natural compounds are highly effective anticancer chemotherapeutic agents, and the targets of plant-derived anticancer agents have been widely reported. In this review, we focus on the main signaling pathways of apoptosis, proliferation, invasion, and metastasis that are regulated by polyphenols, alkaloids, saponins, and polysaccharides. Alkaloids primarily affect apoptosis-related pathways, while polysaccharides primarily target pathways related to proliferation, invasion, and metastasis. Other compounds, such as flavonoids and saponins, affect all of these aspects. The association between compound structures and signaling pathways may play a critical role in drug discovery.

Abstract
The purpose of this study was to evaluate the effects of administered Paeoniflorin (Pae) on periodontal tissues within an experimental periodontitis model. Forty male Wistar rats were used in this study and experimental periodontitis was created in all rats except in the control group (n = 10, first group). In the periodontitis group, experimental periodontitis was created but no other application was performed (n = 10, second group). In the other groups created experimental periodontitis, systemic Pae (n = 10, third group) or saline (n = 10, fourth group) was applied. A biochemical analysis of the gingival vascular endothelial growth factor (VEGF) levels and a histomorphometric analysis (measurements of the area of alveolar bone, alveolar bone resorption, and attachment loss) were performed. In the Pae group, the area of the alveolar bone was increased, while alveolar bone resorption and attachment loss decreased. Gingival VEGF levels increased in all groups that created experimental periodontitis and the greatest increase seen in the Pae group. Histomorphometric and biochemical analyses in this study suggest that Pae has a curative effect on periodontal tissues. However, additional studies are needed to confirm these results.

Abstract
Purpose The aim of this study is to evalute the anti-inflammatory effects of morus migra on experimentally-induced periodontitis in rats. Materials and methods Twenty-four Wistar-albino rats were randomly divided into three groups: control group (C, n=8), experimental periodontitis (PER, n=8), experimental periodontitis and treated with Morus nigra (MN+PER, n=8) (50 mg/kg per day for 21 days). After 21 days, the rats were sacrificed, and alveolar bones were evaluated histopathologically and histometrically analyzed to obtain level of alveolar bone loss. The detection of RANKL and OPG were immunohistochemically performed. Serum and tissue levels of MMP-8 and MMP-13 were also analyzed. Results Morus nigra treatment decreased tissue MMP-8 and MMP-13 levels and there were significant differences in the case of tissue levels of MMP-8 and MMP-13 between groups PER and MN+PER (p=0.035, p=0.041). There were no significant differences among all the groups serum levels of MMP-8 and MMP-13 (p=0.067, p=0.082). In the histometric evaluation, alveolar bone loss was greater in the PER group compared to C and MN groups (p=0.035). Immuno-histochemical staining of RANKL activities were found significantly lower (p=0.037) and OPG activities were found significantly higher in MN+PER group when compared to PER group (p=0.021). Conclusion The present study reveals that systemic administration of Morus nigra significantly inhibited the regional alveolar bone resorption and contributes to periodontal healing in the rat experimental-periodontitis models.

Abstract
OBJECTIVES Appraise the effect of systemic Paeoniflorin (Pae) application on the periodontium during and after induction of experimental periodontitis in the presence of ligature and after its removal. DESIGN Seventy male Wistar rats were separated into seven equal groups. The first group was reserved as healthy control group (Group 1: no periodontitis, no medication) and experimental periodontitis was induced with ligature in the remaining rats. In experimental periodontitis groups, Pae or saline was administered systemically in three differet periods; during the experimental periodontitis induction (period 1), after experimental periodontitis induction which ligature removed (period 2) or ligature kept in position (period 3). Only, one of the groups acted as the control periodontitis group and received no treatment. Experimental periodontitis groups were as follows; Group 2: medication in period 1, Group 3: periodontitis and no medication, Group 4: medication in period 2, Group 5: saline application in period 2, Group 6: medication in period 3, Group 7: saline application in period 3. Matrix metalloproteinases-9 (MMP-9) levels and interleukin-10 (IL-10) levels were detected biochemically and histomorphometric analyses were performed. These analyses included measurements of the area of alveolar bone, the level of alveolar bone, and attachment loss. RESULTS Area of alveolar bone and IL-10 levels were higher in the Pae-administered groups; level of alveolar bone, attachment loss, and MMP-9 levels were correspondingly lower (P < 0.05). The beneficial effects at histomorphometrical and biochemical levels of Pae were the strongest in the rats that were administered Pae after the removal of ligature. CONCLUSIONS Systemically administered Pae had a positive effect on the healing of periodontal tissues. Pae can be used as a new therapeutic agent for periodontal diseases, but microbiology-based studies and more extensive biochemistry-based experimental and clinical studies are needed to address this possibility.

Abstract
BACKGROUND Mastitis is inflammation of a breast (or udder). Angiopoietin-like protein 2 (ANGPTL2) has been found as a key inflammatory mediator in mastitis. Purpose of this research was to investigate the mechanisms about repressing effect of kaempferol on mastitis. METHODS Forty mice were randomly divided into 4 groups (n=10): C57BL/6J control mice, untreated murine mastitis, 10mg/kg kaempferol treated murine mastitis (ip), and 30mg/kg kaempferol treated murine mastitis (ip). Primary cultured mouse mammary epithelial cells (MMEC) were indiscriminately divided into seven groups including control group, 10mmol/L vehicle of kaempferol group, 10μmol/L kaempferol treated group, 20μg/mL LPS treated group, 1μmol/L kaempferol plus LPS treated group, 3μmol/L kaempferol plus LPS treated group, and 10μmol/L kaempferol plus LPS treated group. RESULTS In murine mastitis, kaempferol (10 or 30mg/kg) treatment prevented mastitis development, decreased myeloperoxidase (MPO) production, interleukin (IL)-6 level, tumour necrosis factor-α (TNF-α) concentration, and ANGPTL2 expression. In MMEC, kaempferol (1, 3 or 10μM) reduced MPO production, TNF-α concentration, IL-6 level, and ANGPTL2 expression. CONCLUSIONS The results in present study show that kaempferol modulates the expression of ANGPTL2 to lessen the mastitis in mice.

Abstract
Repair and regeneration of inflammation-induced bone loss remains a clinical challenge. LL37, an antimicrobial peptide, plays critical roles in cell migration, cytokine production, apoptosis, and angiogenesis. Migration of stem cells to the affected site and promotion of vascularization are essential for tissue engineering therapy, including bone regeneration. However, it is largely unknown whether LL37 affects mesenchymal stem cell (MSC) behavior and bone morphogenetic protein 2 (BMP2)-mediated bone repair during the bone pathologic remodeling process. By performing in vitro and in vivo studies with MSCs and a lipopolysaccharide (LPS)-induced mouse calvarial osteolytic bone defect model, we found that LL37 significantly promotes cell differentiation, migration, and proliferation in both unmodified MSCs and BMP2 gene-modified MSCs. Additionally, LL37 inhibited LPS-induced osteoclast formation and bacterial activity in vitro. Furthermore, the combination of LL37 and BMP2 markedly promoted MSC-mediated angiogenesis and bone repair and regeneration in LPS-induced osteolytic defects in mouse calvaria. These findings demonstrate for the first time that LL37 can be a potential candidate drug for promoting osteogenesis and for inhibiting bacterial growth and osteoclastogenesis, and that the combination of BMP2 and LL37 is ideal for MSC-mediated bone regeneration, especially for inflammation-induced bone loss.

Anti-inflammatory, anti-osteoclastic, and antioxidant activities of genistein protect against alveolar bone loss and periodontal tissue degradation in a mouse model of periodontitis.

Abstract
Genistein, a dietary polyphenol primarily found in soy products, has beneficial effects on bone. However, the effect of genistein on inflammatory periodontal destruction has not been investigated in detail. We explored whether genistein protects against lipopolysaccharide (LPS)/ligature-induced periodontitis in mice. We also examined the effect of genistein on LPS-stimulated inflammatory and oxidative stress using RAW 264.7 macrophages and human gingival fibroblasts (hGFs). The results from μCT and histological analyses revealed that intraperitoneal injection of genistein (20 mg/kg body weight) daily for three weeks inhibited LPS-mediated alveolar bone loss and periodontal tissue degradation. The administration of genistein also inhibited osteoclast formation and the expression of inflammation-related molecules in the inflamed region of mice with periodontitis. Treatment with 30-70 μM genistein significantly prevented osteoclast differentiation in receptor activator of nuclear factor κB ligand- or LPS-stimulated macrophages by suppressing the expression of osteoclast-specific molecules. The addition of genistein led to a dose-dependent inhibition of the expression of inflammation-related molecules both in LPS-stimulated macrophages and hGFs. In addition, genistein at 50 μM protected hGFs from LPS-mediated stresses such as mitochondrial impairment and cellular ROS accumulation. However, such protection was significantly diminished by combined treatment with 25 nM bafilomycin A1, a chemical autophagy inhibitor. Collectively, our results indicate that genistein protects against inflammatory periodontal damage by regulating autophagy induction and inhibiting osteoclast activation, the production of inflammation mediators, and mitochondrial oxidative damage. © 2017 Wiley Periodicals, Inc.

Root extractive from Daphne genkwa benefits in wound healing of anal fistula through up-regulation of collagen genes in human skin fibroblasts. Biosci Rep 2017; 37:BSR20170182. [PMID: 28396516 PMCID: PMC5408654 DOI: 10.1042/bsr20170182] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2017] [Revised: 04/10/2017] [Accepted: 04/10/2017] [Indexed: 12/12/2022] Open
Abstract
Wound healing is the main problem in the therapy of anal fistula (AF). Daphne genkwa root has been traditionally used as an agent to soak sutures in operation of AF patients, but its function in wound healing remains largely unclear. The aim of the present study was to illuminate mechanisms of D. genkwa root treatment on AF. In the present study, 60 AF patients after surgery were randomly divided into two groups, external applied with or without the D. genkwa extractive. Wound healing times were compared and granulation tissues were collected. In vitro, we constructed damaged human skin fibroblasts (HSFs) with the treatment of TNF-α (10 μg/ml). Cell Count Kit-8 (CCK-8) and flow cytometry analysis were used to determine the effects of D. genkwa root extractive on cell viability, cell cycle and apoptosis of damaged HSFs. Furthermore, protein levels of TGF-β, COL1A1, COL3A1, Timp-1, matrix metalloproteinase (MMP)-3 (MMP-3) and MEK/ERK signalling pathways were investigated both in vivo and in vitro Results showed that D. genkwa root extractive greatly shortens the wound healing time in AF patients. In granulation tissues and HSFs, treatment with the extractive significantly elevated the expressions of COL1A1, COL3A1, Timp-1, c-fos and Cyclin D1, while reduced the expression of MMP-3 Further detection presented that MEK/ERK signalling was activated after the stimulation of extractive in HSFs. Our study demonstrated that extractive from D. genkwa root could effectively improve wound healing in patients with AF via the up-regulation of fibroblast proliferation and expressions of COL1A1 and COL3A1.
