Aim of the study
The root of Panax notoginseng (PN) is commonly used to treat chronic liver disease with its therapeutic abilities to stop haemorrhage in the circulation, while the PN flower (PN-F) is largely unknown in the biological activities on inflammation and mechanisms of its actions. In this study, the pharmacologic effects of PN-F methanol extract on inflammation were investigated to address potential therapeutic or toxic effects in LPS-stimulated mouse macrophage cells, RAW264.7 cells.Materials and methods
Production of NO, PGE2 and pro-inflammatory cytokines (TNF-α and IL-1β) in supernatant, the expression of iNOS, COX-2 and cytokines, the phosphorylation of MAPK moleduces (ERK1/2, JNK and p38 MAPK), and the activation of NF-κB in PN-F extract were assayed in LPS-stimulated RAW264.7 cells.Results
PN-F extract significantly inhibited the productions of NO, PGE2, TNF-α and IL-1β on the LPS-stimulated RAW264.7 cells. In addition, PN-F extract suppressed the mRNA and protein expressions of iNOS, COX-2, TNF-α and IL-1β in LPS-stimulated RAW264.7 cells. The molecular mechanism of PN-F extract-mediated attenuation in RAW264.7 cells has close a relationship to suppressing the phosphorylation of MAPK molecules such as ERK1/2, JNK and p38 MAPK, and the translocation of NF-κB p65 subunit into nuclear.Conclusion
These results indicate that PN-F extract inhibits LPS-induced inflammatory response via the blocking of NF-κB signaling pathway in macrophages, and demonstrated that PN-F extract possesses anti-inflammatory properties in vitro. 相似文献2.

Aim of the study
Lilium lancifolium is commonly used to treat bronchitis, pneumonia, etc. In this study, we investigated the anti-inflammatory effects of methanol extracts of the root of Lilium lancifolium (LL extracts) in LPS-stimulated Raw264.7 cells.Material and methods
Levels of NO, PGE2 and pro-inflammatory cytokines (IL-6 and TNF-α) in the supernatant fraction were determined using sandwich ELISA. Expression of COX-2 and iNOS, phosphorylation of MAPK subgroups (ERK and JNK), and NF-κB activation in extracts were detected via Western blot and immunocytochemistry assays.Results
The LL extract significantly inhibited NO, PGE2, IL-6 and TNF-α production in LPS-stimulated cells, and suppressed iNOS and COX-2 expression. A mechanism-based study showed that phosphorylation of ERK1/2 and JNK and translocation of the NF-κB p65 subunit into nuclei were inhibited by the LL extract. Furthermore, interleukin-4 and interleukin-13 production in Con A-induced splenocytes was suppressed.Conclusion
These results indicate that anti-inflammatory effects of methanol extracts from Lilium lancifolium are due to downregulation of iNOS and COX-2 via suppression of NF-κB activation and nuclear translocation as well as blocking of ERK and JNK signaling in LPS-stimulated Raw264.7 cells. 相似文献3.

Aims of study
Although the flowers of Chrysanthemum indicum Linné (Asteraceae) have long been used in traditional Korean and Chinese medicine to treat inflammatory diseases, the underlying mechanism(s) by which these effects are induced remains to be defined. We investigated the effects of a 70% ethanolic extract of C. indicum (CIE) on the activities of cellular signaling molecules that mediate inflammatory responses.Materials and methods
Production of NO, PGE2, TNF-α, and IL-1β by ELISA, mRNA and protein expression of iNOS and COX-2, phosphorylation of MAPKs, and activation of NF-κB by RT-PCR and Western blotting were examined in LPS-induced RAW 264.7 macrophages.Results
The CIE strongly inhibited NO, PGE2, TNF-α, and IL-1β production, and also significantly inhibited mRNA and protein expression of iNOS and COX-2 in LPS-induced RAW 264.7 macrophages, in a dose-dependent manner. Furthermore, the CIE clearly suppressed nuclear translocation of NF-κB p65 subunits, which correlated with an inhibitory effect on IκBα phosphorylation. The CIE also attenuated the activation of ERK1/2 and JNK in a dose-dependent manner.Conclusion
Our results suggest that the anti-inflammatory properties of CIE might result from the inhibition of inflammatory mediators, such as NO, PGE2, TNF-α, and IL-1β, via suppression of MAPKs and NF-κB-dependent pathways. 相似文献4.

Aim of the study
The roots of Dichroa febrifuga Lour. have been used as a traditional antimalarial drug and also used in the treatment of productive cough and unstable fever caused by infection in China and Korea. In this study, we evaluated the anti-inflammatory effect and underlying molecular mechanism of aqueous extract of Dichroa febrifuga (AEDF) in C57BL/6 mouse peritoneal macrophages.Materials and methods
The effect of AEDF on proinflammatory cytokine (IL-1β and IL-6) production was analyzed by ELISA and real-time RT-PCR. The effects of AEDF on NF-κB/IκB-α/IKK were measured by reporter assay (in RAW 264.7 cells), EMSA, Western blotting and kinase assay. The effects of AEDF on Akt and MAPKs activity were assayed by Western blotting.Results
AEDF inhibited the production of IL-1β and IL-6, NF-κB activation, IκB-α degradation, and IKK, Akt, ERK1/2 and JNK activities in LPS-stimulated mouse peritoneal macrophages.Conclusions
These results suggest that AEDF inhibits proinflammatory cytokine (IL-1β and IL-6) production in LPS-stimulated mouse peritoneal macrophages, and that these effects are mediated by the inhibition of the activity of IKK/IκB/NF-κB and the phosphorylation of Akt, ERK1/2, and JNK. Our results provide a molecular basis for understanding the inhibitory effects of Dichroa febrifuga roots on endotoxin-mediated inflammation. 相似文献6.

Citrus Unshiu peel (CUP) has been traditionally used in East Asia as a drug for the treatment of vomiting and dyspepsia. However, its effects on inflammation remain unknown. In this study, we investigated the effects of CUP on the production of pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. The research focused on determining whether CUP could inhibit the expression of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 and the activation of nuclear factor (NF)-κB, mitogen-activated protein kinases (MAPKs), as well as the secretion of nitric oxide (NO), prostaglandin (PG) E(2), tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 in LPS-stimulated RAW 264.7 cells. We found that CUP represses LPS-induced iNOS and COX-2 gene expression as well as NO, PGE(2), TNF-α and IL-6 production. Additionally, CUP inhibited the LPS-induced phosphorylation of extracellular signal-regulated kinase (ERK), p38, and c-Jun NH(2)-terminal kinase (JNK) MAPK, and suppressed IκBα degradation and nuclear translocation of NF-κB. Collectively, our results indicate that CUP inhibits the production of various inflammatory mediators via blockade of MAPK phosphorylation pursuant to the inhibition of IκBα degradation and the nuclear translocation of NF-κB. These findings are the first to clarify the mechanism underlying the anti-inflammatory effect exerted by CUP in RAW 264.7 macrophage cells stimulated by inflammatory agents. 相似文献

Rheum rhabarbarum (rhubarb) has long been used for the treatment of inflammation in China and other Asian countries. However, the mechanism underlying the anti-inflammatory activity of this medicinal plant is not fully understood. The present study was designed to investigate the anti-inflammatory effects of anthraquinones, the major constituents in rhubarb, and the molecular mechanism involved in their anti-inflammatory effects.Materials and methods
RAW264.7 cells were stimulated by lipopolysaccharide (LPS) in the presence or absence of the compounds examined. The proliferation of RAW264.7 cells was assayed by the Alamar-Blue method. The quantity of nitric oxide (NO) was determined by Griess assay. The expression of pro-inflammatory cytokines was determined by enzyme-linked immunosorbent assay (ELISA) and quantitative real-time PCR. Inducible nitric oxide synthase (iNOS), inhibitor of nuclear factor κBα (IκBα), extracellular signal-regulated kinase (ERK), p38 mitogen-activated protein kinase (MAPK), c-Jun NH2-terminal kinase (JNK), and Akt/phosphoinositide 3-kinase (PI3K) protein expression levels were determined by Western blotting.Results
Aloe-emodin markedly suppressed the production of NO, interleukin-6 (IL-6), and interleukin-1β (IL-1β) in LPS-stimulated RAW264.7 cells with no apparent cytotoxicity. The mRNA expression levels of iNOS, IL-6, and IL-1β genes were also significantly inhibited by aloe-emodin. Western blot analysis showed that aloe-emodin suppressed LPS-induced iNOS protein expression, IκBα degradation, and the phosphorylation of ERK, p38, JNK, and Akt.Conclusions
These results demonstrate that aloe-emodin is the bioactive component of rhubarb that confers an anti-inflammatory effect through a likely mechanism involving a decrease in pro-inflammatory cytokine production in LPS-induced RAW264.7 macrophages via inhibition of NF-κB, MAPK, and PI3K pathways. 相似文献9.
Effects of taraxasterol on iNOS and COX-2 expression in LPS-induced RAW 264.7 macrophages 总被引:1,自引:0,他引:1
Ethnopharmacological relevance
Taraxasterol was isolated from the Chinese medicinal herb Taraxacum officinale which has been frequently used as a remedy for inflammatory diseases. Our previous study has shown that taraxasterol inhibited lipopolysaccharide (LPS)-induced nitric oxide (NO) and prostaglandin E2 (PGE2) production in RAW 264.7 macrophages. To elucidate the underlying mechanism responsible for these effects, in the present study, we investigated the effects of taraxasterol on inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression, and mitogen-activated protein kinases (MAPKs) signaling pathway in LPS-induced RAW 264.7 macrophages.Materials and methods
RAW 264.7 cells were pretreated with 2.5, 5 and 12.5 μg/ml of taraxasterol 1 h prior to treatment with 1 μg/ml of LPS. The mRNA expression levels of iNOS and COX-2 were examined by RT-PCR. The protein expression levels of iNOS and COX-2, and the phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2), p38 and c-Jun N-terminal kinase (JNK) MAPKs were measured by Western blot.Results
The mRNA and protein expression levels of iNOS and COX-2 were inhibited by taraxasterol in a concentration-dependent manner. Further studies revealed that taraxasterol suppressed the phosphorylation of ERK1/2 and p38 in LPS-induced RAW 264.7 macrophages.Conclusions
These results indicate that taraxasterol inhibits iNOS and COX-2 expression by blocking ERK1/2 and p38 MAPKs signaling pathway. 相似文献10.

Clematis mandshurica Ruprecht root is widely used in Asia as an analgesic and anti-inflammatory agent. This research investigated the anti-inflammatory effects of Clematis mandshurica Ruprecht root extract (CRE) using RAW 264.7 macrophage cells and carrageenan- (CA-) induced rat paw edema.Materials and methods
Production of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, nitric oxide (NO) and prostaglandin E2 (PGE2) in the culture supernatant, mRNA expression of TNF-α, IL-1β, IL-6, iNOS and COX-2, protein expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), nuclear factor-kappa B (NF-κB) and mitogen-activated protein kinases (MAPKs) in the extract were assayed. In addition, the effect of CRE on acute inflammation in vivo was observed using CA-induced rat hind paw edema assay. The changes on the histopathology and histomorphometry of hind paw skins—dorsum and ventrum pedis were observed using CA-treated rats.Results
Treatment with CRE (0.25, 0.5, and 1 mg/mL) resulted in inhibited levels of protein expression of lipopolysaccharide- (LPS-) induced iNOS, COX-2, NF-κB, and MAPKs (ERK, JNK, and p38) as well as production of TNF-α, IL-1β, IL-6, NO, and PGE2 induced by LPS. Consistent with these results, CRE reduced the LPS-induced expressions of these cytokines, iNOS and COX-2 at the mRNA levels in a dose-dependent manner. In particular, results of the CA-induced rat hind paw edema assay showed an anti-edema effect of CRE. In addition, treatment with CRE resulted in dose-dependent inhibition of CA-induced increases of skin thickness, mast cell degranulation, and infiltrated inflammatory, TNF-α, IL-1β, iNOS, and COX-2-positive cells in both dorsum and ventrum pedis skin, respectively.Conclusions
These results demonstrate that CRE exhibits anti-inflammatory activities via decreasing production of pro-inflammatory mediators through suppression of the pathways of NF-κB and MAPKs in LPS-induced macrophage cells. In addition, results of the CA-induced rat hind paw edema assay show an anti-edema effect of CRE. Our findings also support the traditional use of CRE in the inflammatory symptoms of rheumatic arthritis and acute icteric hepatitis. Thus, CRE may have therapeutic potential for a variety of inflammation-mediated diseases and may be developed into potent anti-inflammatory drugs. 相似文献12.

Wu Ling Shen, a folklore name for Xylaria nigripes (XN), is a high value medicinal fungus used in traditional Chinese medicine.Aim of study
The present study aimed to examine the immunomodulatory properties of aqueous (XN-H) and ethanol (XN-E) XN extracts in lipopolysaccharide (LPS)-induced peritoneal macrophage cells of Balb/c mice.Materials and methods
After treating the macrophage cells with LPS (1 μg/ml) and different XN extracts, the immunomodulatory properties were determined by the responses of inflammatory mediators, namely nitrite oxide (NO), prostaglandin E2 (PGE2) and cytokine (IL-1β, IL-6, TNF-α and IFN-γ) production, iNOS, COX-2 and IκB-α expression, and NF-κB activation.Results
Results showed that treatment of macrophages with 5-30 μg/ml of XN-H or XN-E plus 1 μg/ml LPS exhibited no cytotoxic effect on cell viability. At these concentrations, although both XN-H and XN-E showed a dose-dependent inhibitory effect on NO, PGE2, IL-1β, IL-6, TNF-α and IFN-γ production in LPS-stimulated macrophages, a greater potency was noted in the XN-H treated group. RT-PCR assay also showed that XN-H possessed a greater inhibition than XN-E on iNOS and COX-2 RNA expression. Furthermore, XN-H also showed a significant stronger suppression than XN-E on the LPS-induced IκB-α phosphorylation and NF-κB activation. XN-E showed a higher total flavonoid and phenol contents but a lower β-glucan content than XN-H.Conclusion
Taken together, these results conclude that XN-H possesses a stronger anti-inflammatory activity than XN-E, and its mechanism of action could be mediated by inhibiting iNOS and COX-2 expression via the NF-κB signaling pathway, and these activities could be contributed by the β-glucan content. 相似文献13.

Anacardium occidentale is used in traditional African medicine for the treatment of arthritis, fever, aches, pains, and inflammation of the extremities.Aim of the study
In this study, we investigated the molecular mechanisms responsible for anti-inflammatory effects of a stem bark extract of A. occidentale (ANE) in LPS-stimulated microglia.Materials and methods
Nitric oxide (NO), prostaglandin E2 and cytokine (TNFα and IL-6) production were evaluated in supernatants from LPS-stimulated BV-2 cells. Cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS) and microsomal prostaglandin E2 synthase (mPGES-1) protein expressions in rat primary microglia were measured using western blot. The effects of ANE on NF-κB activation and nuclear translocation were evaluated in the luciferase reporter gene assay and ELISA, while ability of ANE to influence IκB phosphorylation was determined using ELISA specific for phospho-IκB. The involvement of MAPK phosphorylation in the anti-inflammatory actions of ANE was evaluated using specific ELISA for phospho-p38, phospho-p42/44 and phospho-JNK. The MTT assay was used to determine the effect of ANE on BV-2 microglia viability.Results
ANE (25–100 μg/ml) produced significant (p<0.05) reduction in the production of NO, PGE2, TNFα and IL-6 in BV-2 microglia stimulated with LPS for 24 h. Pre-treatment with ANE caused a significant (p<0.05) inhibition of COX-2, iNOS and mPGES-1 protein expressions in the rat primary microglia. Further experiments showed that ANE inhibited COX-2 and iNOS protein expression via IκB-mediated nuclear translocation and transactivation of NF-κB. Our studies also revealed that ANE produced significant (p<0.05) and dose-dependent inhibition of p38, p42/44 and JNK MAPK phosphorylation in LPS-activated BV-2 microglia.Conclusions
We conclude that ANE has an anti-inflammatory property related to inhibition of inflammation-associated cytokine production as well as iNOS and COX-2 gene expression by blocking NF-κB and MAPK pathways in the microglia. It is also suggested that mPGES-1 inhibition contributes to the effect of ANE on PGE2 production in the microglia. 相似文献16.

The roots of Achyranthes japonica Nakai have been used in traditional herbal medicine for the treatment of edema and arthritis in Korea.Aim of the study
In this study, we investigated the molecular mechanism responsible for anti-inflammatory effects of the aqueous extract of A. japonica roots (AJ) in LPS-stimulated macrophages.Materials and methods
Nitric oxide (NO) production and as inducible nitric oxide synthase (iNOS) expression were examined in TG-elicited peritoneal macrophages and RAW 264.7 cells. Cell viability was monitored by MTT assay. Protein and mRNA expressions were determined by Western blotting and RT-PCR, respectively. The activity of NF-κB and Nrf2 were examined by EMSA, immunocytochemistry or reporter assay.Results
AJ inhibited LPS-induced NO secretion as well as iNOS expression, without affecting cell viability. Furthermore, AJ suppressed LPS-induced NF-κB activation, degradation of IκB-α, phosphorylation of extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK) and p38. Further study demonstrated that AJ induced heme oxygenase-1 (HO-1) gene expression via nuclear translocation and transactivation of Nrf2. In addition, the inhibitory effects of AJ on iNOS expression were abrogated by small interfering RNA-mediated knock-down of HO-1.Conclusions
These results suggest that AJ suppresses LPS-induced NO production and iNOS expression in macrophages through the inhibition of IκB/NF-κB and MAPK as well as the Nrf2-mediated HO-1 induction. These findings provide the scientific rationale for anti-inflammatory therapeutic use of A. japonica roots. 相似文献17.
Aim of the study
The present study was performed to investigate the underlying mechanisms of anti-inflammatory effects with the extract of Euonymus alatus (EEA), and specially focused on nuclear factor κB (NF-κB) signaling pathway by targeting the IκB kinase β (IKKβ).Materials and methods
The effect of EEA for IKKβ activity was analyzed using an immobilized metal affinity for phosphochemicals (IMAP)-based time-resolved fluorescence resonance energy transfer (TR-FRET) assay. The effect of EEA on lipopolysaccharide (LPS)-induced NF-κB activation in murine macrophage RAW 264.7 cells with western blotting and immunofluorescent staining was evaluated.Results
IKKβ studies based on IMAP-TR-FRET showed that EEA possesses a potent IKKβ inhibitory activity with IC50 value of 11.83 μg/ml. EEA (10, 30 μg/ml) also attenuated the LPS-induced IκBα phosphorylation/degradation, NF-κB translocation and subsequent NO synthesis in RAW 264.7 cells.Conclusions
These results suggest that EEA abrogates LPS-induced NF-κB signaling pathway by targeting the IKKβ in RAW 264.7 cells and these properties may provide a molecular basis for understanding the inhibitory effects of EEA on LPS-mediated inflammation. 相似文献18.

Aim of the study
This paper aimed to elucidate the anti-inflammatory effects of EtOAc fraction prepared from Melilotus suaveolens Ledeb ethanol extract with a cellular model of LPS-stimulated RAW 264.7 cell.Materials and methods
Some key pro-inflammatory cytokines and mediators including IL-1β, IL-6, NO, iNOS, COX-2 and TNF-α, two important anti-inflammatory cytokines and mediators IL-10 and HO-1, I-κB and NF-κB were studied by sandwich ELISA, real-time PCR, western blot analysis and immunocytochemistry. At last a HPLC fingerprint was taken to evaluate the fraction.Results
The EtOAc fraction could significantly inhibit the production of IL-1β, IL-6, NO, TNF-α, COX-2 in LPS-stimulated cell than that of single LPS-stimulated cell (p < 0.01 or p < 0.05), and the extract could increase the production of IL-10 and HO-1 than that of single LPS intervention cell (p < 0.01 or p < 0.05). Meanwhile, the extract also could inhibit the production of NF-κB compared to single LPS-stimulated cell. All the results showed that the extract had a good anti-inflammatory effect on LPS-stimulated RAW264.7 cell.Conclusions
Taken together, the anti-inflammatory actions of M. suaveolens Ledeb EtOAc fraction might be due to the down-regulation of IL-1β, IL-6, NO, TNF-α and COX-2 via the suppression of NF-κB activation, and another pathway was up regulating the production of IL-10 and HO-1. Meanwhile, the EtOAc fraction might be further studied to isolate the active anti-inflammatory ingredients besides coumarin. 相似文献19.
Fermentation improves anti-inflammatory effect of sipjeondaebotang on LPS-stimulated RAW 264.7 cells
Oh YC Cho WK Jeong YH Im GY Yang MC Ma JY 《The American journal of Chinese medicine》2012,40(4):813-831
Sipjeondaebotang (SJ) has been used as a traditional drug in east-Asian countries. In this study, to provide insight into the biological effects of SJ and SJ fermented by Lactobacillus, we investigated their effects on lipopolysaccharide (LPS)-mediated inflammation in macrophages. The investigation was focused on whether SJ and fermented SJ could inhibit the production of pro-inflammatory mediators such as prostaglandin (PG) E(2) and nitric oxide (NO) as well as the expressions of cyclooxygenase (COX)-2, inducible nitric oxide synthase (iNOS), tumor necrosis factor (TNF)-α, mitogen-activated protein kinases (MAPKs) and nuclear factor (NF)-κB in LPS-stimulated RAW 264.7 cells. We found that SJ modestly inhibited LPS-induced PGE(2), NO and TNF-α production as well as the expressions of COX-2 and iNOS. Interestingly, fermentation significantly increased its inhibitory effect on the expression of all pro-inflammatory mediators. Furthermore, fermented SJ exhibited increased inhibition of p38 MAPK and c-Jun NH(2)-terminal kinase (JNK) MAPK phosphorylation as well as NF-κB p65 translocation by reduced IκBα degradation compared with either untreated controls or unfermented SJ. High performance liquid chromatography (HPLC) analysis showed fermentation by Lactobacillus increases liquiritigenin and cinnamyl alcohol contained in SJ, which are known for their anti-inflammatory activities. Finally, SJ fermented by Lactobacillus exerted potent anti-inflammatory activity by inhibiting MAPK and NF-κB signaling in RAW 264.7 cells. 相似文献
