Project description:To identify biomarkers regulated by traditional Chinese medicine Astragalus membranaceus Fischer Bge. var. mongolicus Bge. Hsiao in colorectal cancer. We have identified several differentially expressed genes including microRNAs using Affymetrix HTA-2.0 array. In this dataset, we include the expression data obtained from colon cancer cell line HCT116 grafted into nude mice. The mice was treated either water or traditional Chinese medicine Astragalus membranaceus for 28 days. These data are used to obtain 1425 genes that are differentially expressed in response to Astragalus membranaceus treatment.

Project description:Astragali Radix (AR) is a commonly used herbal drug in Traditional Chinese Medicine, and widely used for the treatment of diabetes, cardiovascular diseases, nephropathy and neuropathy. The main source of AR is the dried root of Astragalus membranaceus var. mongholicus (Bge.) Hsiao in China, and both cultivated and wild ARs are used in the clinic. Systematic comparison of cultivated AR and wild AR should be performed to ensure the efficacy and safety in clinic. In this study, the chemical compositions of two different ARs, collected in Shanxi (wild) and Gansu (cultivated) Provinces, were compared by NMR based metabolic fingerprint coupled with multivariate analysis. Then SX-AR and GS-AR induced metabolic changes of endogenous metabolites in mice were also compared. The results showed that SX-AR and GS-AR differed significantly not only in the primary metabolites, but also the secondary metabolites. However, alterations of endogenous metabolites in serum, lung, liver and spleen were relatively small between them. This study provided a novel and valuable method for consistency and diversity evaluation of herbal drugs, and further studies should be conducted on the difference of polysaccharide as well as biological effect between the two kinds of ARs.

Project description:Plants are known to be responsive to volatiles, but knowledge about the molecular players involved in transducing their perception remain scarce. Here the response of Arabidopsis thaliana to E-2-hexenal, one of the green leaf volatiles that are produced upon wounding, herbivory or infection with pathogens is studied. We have taken a transcriptomics approach to identify genes that are induced by E-2-hexenal but not by defense hormones. In three independent biological experiments, Arabidopsis plants, ecotype Columbia (Col-0), were exposed either to 3 µM aerial E-2-hexenal or to the carrier MeOH for the mock treatment and rosette leaves were harvested after 1h, 3h and 24h.

Project description:Arctic alpine species experience extended periods of cold and unpredictable conditions during flowering. Thus, often, alpine plants use both sexual and asexual means of reproduction to maximise fitness and ensure reproductive success. We used the arctic alpine perennial Arabis alpina to explore the role of prolonged cold exposure on adventitious rooting. We exposed plants to 4 °C for different durations and scored the presence of adventitious roots on the main stem and axillary branches. Our physiological studies demonstrated the presence of adventitious roots after 21 weeks at 4 °C saturating the effect of cold on this process. Notably, adventitious roots on the main stem developingin specific internodes allowed us to identify the gene regulatory network involved in the formation of adventitious roots in cold using transcriptomics. These data and histological studies indicated that adventitious roots in A. alpina stems initiate during cold exposure and emerge after plants experience growth promoting conditions. While the initiation of adventitious root was not associated with changes of DR5 auxin response and free endogenous auxin level in the stems, the emergence of the adventitious root primordia was. Using the transcriptomic data, we discerned the sequential hormone responses occurring in various stages of adventitious root formation and identified supplementary pathways putatively involved in adventitious root emergence, such as glucosinolate metabolism. Together, our results highlight the role of low temperature during clonal growth in alpine plants and provide insights on the molecular mechanisms involved at distinct stages of adventitious rooting.
