Smiglaside A ameliorates LPS-induced acute lung injury by modulating macrophage polarization via AMPK-PPAR γ pathway.
In this study, we evaluated the effects of the natural product smiglaside A, a phenylpropanoid glycoside isolated from the traditional Chinese medicinal herb Smilax riparia, on macrophage polarization and investigated the underlying mechanisms. We found that smiglaside A promoted M2 polarization and reduced M1 polarization in LPS-stimulated RAW264.7 cells and primary mouse peritoneal macrophages. Further mechanistic studies showed that the promoting effect of smiglaside A on M2 polarization was attenuated by pharmacological inhibition or gene silencing of AMP-activated protein kinase (AMPK) or peroxisome proliferator-activ...

Anti-inflammatory activity of the decoction of Forsythia suspensa (Thunb.) Vahl is related to Nrf2 and A20
ConclusionWFF activated Nrf2 and expressed A20. Given that Nrf2 suppresses inflammation and A20 broadly disrupts inflammatory signaling cascades, our results suggest that the anti-inflammatory activity of WFF is attributable to Nrf2 and A20.Graphical abstract

Ethanol Extract of Lycopus lucidus Turcz. ex Benth Inhibits Metastasis by Downregulation of Runx-2 in Mouse Colon Cancer Cells.
This study aims to elucidate the effects of ethanol extracts of LT (ELT) relative to the role of Runt-related transcription factor- (Runx-) 2 in the invasive and metastatic potentials of mouse colon cancer to determine the underlying mechanisms involved. ELT was evaluated for the antimetastasis activity using CT-26 colon cancer using wound healing, transwell matrigel, and western blot analysis. We used Runx-2-specific siRNA to further determine the relationship between Runx-2 and matrix metalloprotease- (MMP-) 9 in the migration and invasion of CT-26 cells. Runx-2 was first demonstrated to be a transcription factor that pl...

Contribution of human UDP-glucuronosyltransferases to the antioxidant effects of propolis, artichoke and silymarin
Conclusion: In conclusion, this study provides a possible molecular mechanism for protective antioxidant effects associated with the herbal drugs propolis, artichoke and silymarin. The herbal drug-mediated transcriptional upregulation of human detoxifying UGT1A enzymes via activation of AhR and Nrf2 leads to reduced hydrogen peroxide and oxidative stress. Because of UGT1A activation, the intake of these drugs could affect the therapeutic efficacy of other drugs when these also undergo metabolism by glucuronidation.Graphical abstract

Dendrobium moniliforme stem extract inhibits lipoteichoic acid-induced inflammatory responses by upregulation of heme oxygenase-1.
In this study, we investigated anti-inflammatory effects of the aqueous extract of D. moniliforme stems (DM) in response to lipoteichoic acid (LTA), a major constituent of the cell wall of Gram-positive bacteria. DM inhibited LTA-induced expression of a pro-inflammatory mediator inducible nitric oxide synthase (iNOS) in the murine macrophages. And DM induced expression of heme oxygenase-1 (HO-1) at the transcriptional level. Conversely, the knockdown of HO-1 expression by siRNA markedly reversed the inhibitory effects of DM on LTA-induced iNOS expression. We also demonstrated that nuclear translocation of Nrf2 was increase...

In vitro inhibitory properties of sesquiterpenes from Chloranthus serratus on cell motility via down-regulation of LIMK1 activation in human breast cancer
Conclusioncollectively, it was concluded that SERA exhibited significant inhibitory effects on breast cancer cells migration, and these effects of this sesquiterpene are due to its properties reducing the activation of LIM kinase 1.Graphical Abstract

Isoquercitrin promotes the osteogenic differentiation of osteoblasts and BMSCs via the RUNX2 or BMP-pathway.
Authors: Li M, Zhang C, Li X, Lv Z, Chen Y, Zhao J
Abstract
Isoquercitrin is widely present in fruits, vegetables and medicinal herbs. As a natural phytoestrogen, isoquercitrin has been considered a possible osteoporosis prevention option to avoid the risk of hormone therapy. In this work, we studied the effects of isoquercitrin on the cell proliferation and osteogenic differentiation of osteoblasts and bone mesenchymal stem cells (BMSCs), as well as the molecular mechanism of isoquercitrin action. The cell proliferation of osteoblasts and BMSCs was promoted by isoquercitrin at low concentrations. High concentratio...

Anti-inflammatory effect of the extracts from the branch of Taxillus yadoriki being parasitic in Neolitsea sericea in LPS-stimulated RAW264.7 cells
In this study, we evaluated the anti-inflammatory effect of extracts of branch from Taxillus yadoriki being parasitic in Neolitsea sericea (TY-NS-B) using in vitro model. TY-NS-B significantly inhibited LPS-induced secretion of NO and PGE2 in RAW264.7 cells. TY-NS-B was also observed to inhibit LPS-mediated iNOS COX-2 expression. In addition, TY-NS-B attenuated production of inflammatory cytokines such as TNF-α and IL-1β induced by LPS. TY-NS-B blocked LPS-mediated inhibitor of IκB-α, and inhibited p65 translocation to the nucleus and NF-κB activation. Furthermore, TY-NS-B reduced the phosphorylation of MAPKs such as ...

Cellular mechanism for herbal medicine Junchoto to facilitate intestinal Cl − /water secretion that involves cAMP-dependent activation of CFTR
AbstractConstipation is a common symptom frequently compromising the quality of daily life. Several mechanistically different drugs have been used to mitigate constipation, including Japanese herbal (Kampo) medicines. However, the mechanisms of their actions are often not well understood. Here we aimed to investigate the molecular mechanisms underlying the effects of Junchoto (JCT), a Kampo medicine empirically prescribed for chronic constipation. Cl− channel activity was measured by the patch-clamp method in human cystic fibrosis transmembrane conductance regulator (CFTR)-expressing HEK293T cells and human intestinal Ca...

Shikonin upregulates the expression of drug-metabolizing enzymes and drug transporters in primary rat hepatocytes
Conclusions Shikonin effectively upregulates the transcription of CYP isozymes, phase II detoxification enzymes, and phase III membrane transporters and this function is at least partially through activation of AhR and Nrf2. Moreover, Nrf2 activation is dependent on mitogen-activated protein kinases. Graphical abstract
