Project description:Pien Tze Huang (PZH) is herbal traditional Chinese medicine which was widely utilized in Asia for hepatic diseases. We constructed two groups hepatic fibrosis mice model using CCl4, one group using PZH treatment and another group replacing PZH with double distilled water. All 12 mice were fed for 8 weeks and then killed to have their liver tissue taken out. Small RNA-seq were used to identify miRNAs of PZH medicine effect for hepatic fibrosis. We found the expression of these miRNAs (mmu-miR-205-5p, mmu-miR-3064-5p, mmu-miR-205-5p, mmu-miR-370-3p, mmu-miR-665-3p) were changed in PZH medicine treatment for hepatic fibrosis study. Furthermore, Hmga2 and Fgf9, miRNAs corresponding target genes (Sp4, Slc2a6, Tln2, Hmga2, Ank3, Pax9, Fgf9), have been reported association with hepatic fibrosis.
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:Potentilla indica and Melastoma dodecandrum lour are medicinal herbs used in traditional Chinese medicine. We sampled the plants from Nanyang Technological University's herb garden for transcriptomics analysis.
Project description:Capsicum frutescens is one of the chilli varieties, with erect, highly pungent fruits. This variety is used to prepare hot sauces, chilli concentrates, and oleoresin. Its fruits are also used in traditional Indian medicine to treat arthritis and zoster related pain management. Infection by Polyphagotarsonemus latus commonly called as the Broad mite in chilli, make the leaves turn coppery and dark, show symptoms of leaf curl and stunted growth that eventually results in low yield and economic loss. We carried out gel-free, labelled mass spectrometry-based quantitative proteomic analysis of leaves and apical meristems of healthy and infected plants. We identified a total of 5799 proteins, of which total of which, 1677 proteins found to dysregulated in infested plants.
Project description:Phytophthora cinnamomi Rands is a cosmopolite and phyllophagous pathogen of woody plants which during the last couple of centuries has spread all over the world from its center of origin in Southeast Asia. Despite Chinese cork tree (Quercus variabilis Blume) forests native to Asia being generally healthy, the populations of cork trees (Quercus suber L.) in Europe have been decimated by P. cinnamomi. The present study tries to identify the differences in the early proteomic and metabolomic response of these two tree species that lead to their contrasting susceptibility to P. cinnamomi attack. By using micropropagated clonal plants, we tried to minimize the plant-to-plant differences in the defense response that is maximized by the high intraspecific genetic variability inherent to the Quercus genus. The evolution on the content of Phytophthora proteins in the roots during the first 36 hours after inoculation suggest a slower infection process in Q. variabilis plants. These plants displayed a significant decrease in sugars in the roots, together with a downregulation of proteins related to carbon metabolism. In the leaves, the biggest changes in proteomic profiling were observed 16 hours after inoculation. and included increased abundance of peroxidases, superoxidedismutases and gluthatione S-transferases in Q. variabilis plants, which probably aided its resistance against P. cinnamomi attack.
