Project description:At present, with the accelerating pace of life, increase in work pressure, lack of exercise, irregularity of diet and rest, and problems of environmental pollution, people with immunodeficiency are gradually increasing in the modern population. Some Chinese herbal medicines can improve the immunity of the human body, and have less and mild side or toxic effects, so that the study on this kind of traditional Chinese medicines and its mechanism has become an urgent problem to be solved. In recent years, studies have shown that Shcisandrol A (Sch A) can regulate immune function and inhibit the inflammation of nervous system. In this study, mRNA expression profile chip was used to screen the differentially expressed genes related to the effect of Sch A on immunodepressed mice induced by cyclophosphamide (Cy), and the differentially expressed gene-telated pathways were analyzed by gene ontology function cluster analysis, and finally qPCR was applied to verify the 5 genes that might be related to the regulation of Sch A on the mice’s immune functions, to provide a theoretical basis for screening the drug targets on which Sch A could act to regulate the mice’s immune functions.

Project description:Herbal compatibility is the knowledge of which herbs to combine in traditional Chinese medicine (TCM) formulations. The lack of understanding of herbal compatibility is one of the key problems for the application and popularization of TCM in western society. Because of the chemical complexity of herbal medicines, it is simpler to begin to conduct compatibility research based on herbs rather than component plant secondary metabolites. We have used transcriptome analysis to explore the effects and interactions of two plant extracts (Kushen and Baituling) combined in Compound Kushen Injection (CKI). Based on shared chemical compounds and in vitro cytotoxicity comparisons, we found that both the major compounds in CKI, and the cytotoxicity effects of CKI were mainly derived from the extract of Kushen (Sophorae flavescentis). We generated and analyzed transcriptome data from MDA-MB-231 cells treated with single-herb extracts or CKI and results showed that Kushen contributed to the perturbation of the majority of cytotoxicity/cancer related pathways in CKI such as cell cycle and DNA replication. We also found that Baituling (Heterosmilax yunnanensis Gagnep) could not only enhance the cytotoxic effects of Kushen in CKI, but also activate immune-related pathways. Our analyses predicted that IL-1[beta] gene expression was upregulated by Baituling in CKI and we confirmed that IL-1[beta] protein expression was increased using an ELISA assay. Altogether, these findings help to explain the rationale for combining Kushen and Baituling in CKI, and show that transcriptome analysis using single herb extracts is an effective method for understanding herbal compatibility in TCM.

Project description:Asterids is one of the major plant clades comprising of many commercially important medicinal species. One of the major concerns in medicinal plant industry is adulteration/contamination resulting from misidentification of herbal plants. This study reports the construction and validation of a microarray capable of fingerprinting medicinally important species from the Asterids clade.

Project description:The immune system is our body’s defense mechanism, which helps us to resist foreign pathogens and cancer cells in the body. However, if the immune system is too weak, too strong, or unbalanced, it will be susceptible to get bacterial and viral infections, unable to fight cancer, or cause allergies, autoimmune and rheumatic diseases. At present, there is no good western medicine to strengthen immunity when the body is insufficient immunity. However, strong immunity causes autoimmune diseases and need to be treated by steroids and immunosuppressive agents. These drugs have limited efficacy and often have many side effects. In the clinical practice of traditional Chinese medicine, tonify qi, supplement blood and nourish yin are often used to enhance immunity. However, there is no clinical test to demonstrate the modulation of immune response after traditional Chinese medicine treatment.
In our preliminary study, the investigators identified that the basic immune response of cancer patients is weaker than healthy people by testing the level of IFN-r (promoting T cell activity, anti-tumor, anti-viral), TNF-a (promoting B cell proliferation, producing antibodies, anti-tumor, anti-viral) and IL-2 (regulate the proliferation and differentiation). Besides, some Chinese herbal extracts can significantly stimulate the immune response higher than the general average basic immunity of cancer patients. Further, we will use the stimulatory Chinese medicine extract to administer to cancer patients and examine the immune response of cancer patients after taking them. Therefore, this test can provide actual data on the basic immunity of healthy people or cancer patients and the modulation of immune response by traditional Chinese medicine treatment. This analysis platform provides patients to select the medicines that can enhance the immune response for individuals and analyze the changes of the immune response after conditioning with the candidate Chinese medicines. Therefore, this test could be applied clinically to validate the immunological regulation of Chinese herbal medicine as well as analyze the immunological modulation against different cancer by various Chinese herbal medicine.

Project description:Dehydroeffusol (DHE) is a rare compound of phenanthrene class isolated from Medulla Junci used in Traditional Chinese herbal medicines. Initial biological evaluation of this compound reveals in vitro and in vivo anticancer ac-tivities. We performed a shotgun proteomic analysis using Orbitrap liquid chromatography-tandem mass spectrometry to investigate the changes in the protein profiles in cancer cells upon DHE treatment. DHE affected cancer-associated signaling pathways, including NF-B, β-catenin and endoplasmic reticulum stress. Through quantitative pathway and key-node analysis of the proteomics data, activating transcription factor 2 (ATF-2) and c-Jun kinase (JNK) were found to be the key components in DHE’s modulated biological pathways. Furthermore, based on the pathway analysis as well as chemical similarity, DHE is predicted to be a phytoestrogen. Our predictions derived from proteomic, bio-informatic and chemoinformatic analyses were validated with individual cell-based experiments. In addition to elucidating the major mechanisms of action of DHE, our study demonstrates an effective workflow for identifying the mechanisms of action of bioactive compounds through shotgun proteomic analysis.

Project description:Echinacea, native to the Canadian prairies and the prairie states of the United States, has a long tradition as a folk medicine for the Native Americans. Currently, Echinacea are among the top 10 selling herbal medicines in the U.S. and Europe, due to increasing popularity for the treatment of common cold and ability to stimulate the immune system. However, the genetic relationships within the species of this genus are unclear, which makes difficult the authentication of the species used for the medicinal industry. We report the construction of a novel Subtracted Diversity Array (SDA) for Echinacea species and demonstrate the potential of this array for isolating highly polymorphic sequences.
