Protosappanin A exerts anti-neuroinflammatory effect by inhibiting JAK2-STAT3 pathway in lipopolysaccharide-induced BV2 microglia / 中国天然药物

Microglial activation and resultant neuroinflammatory response are implicated in various brain diseases including Alzheimer's disease and Parkinson's disease. Treatment with anti-neuroinflammatory agents could provide therapeutic benefits for such disorders. Protosappanin A (PTA) is a major bioactive ingredient isolated from Caesalpinia sappan L.. In this work, the anti-neuroinflammatory effects of PTA on LPS-stimulated BV2 cells were investigated and the underlying mechanisms were explored. Results showed that PTA significantly inhibited the production of TNF-α and IL-1β in LPS-activated BV2 microglia. Moreover, the mRNA expressions of IL-6, IL-1β, and MCP-1 were reduced by PTA in a dose-dependent manner. Furthermore, PTA suppressed JAK2/STAT3-dependent inflammation pathway through down-regulating the phosphorylation of JAK2 and STAT3, as well as STAT3 nuclear translocation against LPS treatment. These observations suggested a novel role for PTA in regulating LPS-induced neuroinflammatory injuries.

Identification and function analysis of target group for cardioprotection of Baoyuan decoction / 中国中药杂志

Baoyuan decoction (BYD) is a well-known traditional Chinese medicine formula for coronary heart disease with Qi deficiency. However, the detailed pharmacological mechanism of BYD is still unknown because of its complicated chemical compositions. In this study, we synthesized a kind of solid beads with benzophenone groups on its surface. Benzophenone can be activated and chemically cross-linked with the C-H bonds of the chemical compositions in BYD (BYD beads) under UV activation. We thus captured all the target proteins from mouse heart tissue lysates by using BYD beads. Based on proteomics analysis, we discovered totally 46 potential binding target proteins, most of which were located in mitochondria. KEGG analysis revealed that these target proteins were mainly associated with TCA cycle and amino acid metabolism signaling pathways, suggesting that the cardioprotection of BYD might be associated with regulating mitochondrial function and energy production. Moreover, JC-1 staining analysis also confirmed the protective effect of BYD on mitochondrial damage. In summary, our findings elucidated the potential mechanism of BYD on cardioprotection through "target fishing" strategy, and further explained its traditional efficacy in the molecular level. In addition, we also provide an approach for investigating the target group of complicated compositions in Chinese herbal formula. This novel method may provide a methodological reference for exploring the pharmacological mechanism of traditional Chinese formula in the future.

Identification and function analysis of neuroprotective targets group of modified Wuzi Yanzong pill / 中国中药杂志

Targets group identification in complex Chinese medicine system is a key step for revealing the potential mechanism of Chinese medicine. The solid beads with magnetic core and benzophenone-modified surface were made in our study, and then benzophenone was activated and cross-linked with the C-H bonds of chemical compositions in Chinese medicines under UV excitation. Thus the chemical compositions of modified Wuzi Yanzong pill(MWP) were linked to the solid bead surface, and enriched the neuroprotective targets group of MWP after being co-incubated with nerve cell lysate. We performed proteomics analysis on these targets and discovereda total of 32 potential binding targets. KEGG analysis revealed that these targets were mainly associated with Hippo and Cell cycle signaling pathways, suggesting that MWP might be involved in regulating the proliferation and differentiation of neural stem cells. Our findings elucidate the potential targets and mechanism of MWP on anti-dementia and neuroprotection, and further providean approach for investigating the targets group in complex Chinese medicine system. This novel method may provide methodological references for exploring the pharmacological mechanism of Chinese medicinal formulae in the future.

Hydrophidae identification through analysis on cytochrome c oxydase I（COI） and ribosome 16s rDNA gene barcode / 中国中药杂志

Hydrophidae, one of the precious traditional Chinese medicines, is generally drily preserved to prevent corruption, but it is hard to identify the species of Hydrophidae through the appearance because of the change due to the drying process. The identification through analysis on gene barcode, a new technique in species identification, can avoid this problem. The gene barcodes of the 5 species of Hydrophidae, Lapemis hardwickii, Hydrophis fasciatus, Aipysurus eydouxii, Hydrophis belcher and Hydrophis lamberti, were acquired through DNA extraction and gene sequencing. These barcodes were then in sequence alignment and test the identification efficiency by BLAST. Our results showed that the 16S rDNA sequences identified Hydrophidae briefly and the COI sequenceshad obvious difference between intra-and inter-species, indicating that DNA bar-coding was an efficiency method of Hydrophidae identification.

Inhibitory effects of acteoside on LPS-induced inflammatory response on BV-2 microglial cells / 中国中药杂志

To investigate the inhibitory effects of acteoside (ACT) on BV-2 microglial cells and the potential mechanism,LPS was used to treat BV-2 cells with or without ACT (12.5,25,50 μmol•L ⁻¹). Then, the expressions of inflammatory factors (NO,TNF-α,IL-6) and inflammation related proteins (iNOS,COX-2,p-IKKβ,IKKβ,p-ⅠκB,ⅠκB) were detected. In addition,the nuclear translocation of NF-κB was explored. The results showed that ACT could significantly suppress the inflammatory response against LPS stimulation by decreasing the expressions of NO,IL-6,TNF-α,iNOS,COX-2 and the phosphorylations of IKKβ and IκB. Moreover,the nuclear translocation of NF-κB p65 was inhibited by ACT. Taken together, ACT could significantly inhibit the inflammatory response of BV-2 microglial cells which were induced by LPS via inhibition of NF-κB signaling pathway.
