Project description:We found the bone marrow stromal-derived neural progenitor cells secretome have the neural protection effect. Proteomic analysis was performed nn order to analyze the protection factor in the secretome. Keywords: Neural protection, secretome
Project description:Study purpose: to explore the entire spectrum of proteomic and genomic changes (amongst others) involved in diseases and in healthy/control populations. The Study is designed to discover biomarkers, develop and validate diagnostic assays, instruments and therapeutics as well as other medical research. Specifically, researchers may analyze proteins, RNA, DNA copy number changes, including large and small (1,000-100,000 kb) scale rearrangements, transcription profiles, epigenetic modifications, sequence variation, and sequence in both diseased tissue and case-matched germline DNA from Subjects.
Project description:Desmoplastic small round cell tumor (DSRCT) is an aggressive malignancy that occurs predominantly in young adult males and is characterized by abdominopelvic sarcomatosis exhibiting multi-lineage cellular nests of epithelial, muscular, mesenchymal, and neural differentiation admixed with desmoplastic stroma. Prior to the recognition of the disease as a distinct clinical entity, DSRCT was invariably misclassified as poorly differentiated atypical cancer of the testes, ovary, mesentery, or gastrointestinal tract, and the chemotherapies used for those malignancies elicited poor clinical response. As previously reported, a tectonic shift in the treatment of these patients occurred after researchers made two astute observations: 1) DSRCT microscopically resembles other small round “blue cell” sarcoma subtypes (e.g., ES, rhabdomyosarcoma, synovial sarcoma), and 2) DSRCT and ES have the same N-terminal EWSR1 fusion partner. Proteomic analysis using a reverse-phase protein lysate array (RPPA) was used to elucidate biomarkers that distinguish DSRCT from adjacent normal tissue and Ewing sarcoma. This proteomic analysis revealed novel proteins, such as the androgen receptor and Syk, that may be susceptible to drug targeting, as well as oncogenic pathways like Akt-PI3K that are highly expressed in DSRCT.
