Project description:Phosphopeptides were purified using Titansphere. Before MS analysis, phosphopeptides were desalted using StageTips with C18 Empore disk membranes. Phosphopeptides were analysed by Orbitrap MS.The obtained MS and MS/MS spectra data were searched against Kazusa DNA Research Institute published lotus EST database using the MASCOT program (FDR<1%).

Project description:Ginsenosides are a class of natural product triterpene saponins and almost exclusively in the plant genus Panax which has a long history of use as dietary supplements. Pharmacological research demonstrated that ginsenosides have multiple bioactivities. Ginsenoside is produced at high levels within Panax japonicus, and we have performed Lable-free quantitaion analysis of multiple tissues from this species in order to investigate the biosynthetic genes required for producing ginsenoside.
Project description:To test if scRNA-seq contains sufficient phylogenetic information to reconstruct a population history of cancer, immunosuppressed NU/J mice were injected with human cancer cells (MDA-MB-231-LM2). The tumors that develop are derived from the same population and thus share a common ancestor, but evolved independently in each mouse and should form separate clades on reconstructed phylogenetic trees when analysed together. We explore and compare results of phylogenetic analyses based on both expression levels and SNVs called from our scRNA-seq data. Both techniques are shown to be useful for reconstructing phylogenetic relationships between cells, refecting the clonal composition of a tumor. Without an explicit error model, standardized expression values appears to be more powerful and informative than the SNV values at a lower computational cost, due to being a by-product of standard expression analysis. Our results suggest that scRNA-seq can be a competitive alternative or useful addition to conventional scDNA-seq phylogenetic reconstruction. Our results open up a new direction of somatic phylogenetics based on scRNA-seq data. Further research is required to refne and improve these approaches to capture the full picture of somatic evolutionary dynamics in cancer.
