Project description:Several novel potential oncogenic and tumor suppressor miRNAs were identified by using the appropriate controls for stem cells. Expression profiles for human miRNAs in six samples were generated. The Agilent platform GPL7731 was used to analyze six RNA samples: CD133- human NPC, CD133+ human NPC, CD133- B4 glioma, CD133+ B4 Glioma, CD133+ NCH441 glioma, CD133+ NCH644 glioma

Project description:To identify the gene expression signature associated with CD133, the well-known stem cell markers, three gastric cancer cell lines were obtained (KATO-III, SNU201 and SNU601). Cultured gastric cancer celllines were sorted into CD133+ and CD133- population by FACS sorting and microarray-based gene expression profiling was performed.

Project description:Given the very substantial heterogeneity of most human cancers, it is likely that most cancer therapeutics will be active in only a small fraction of any population of patients. As such, the development of new therapeutics, coupled with methods to match a therapy with the individual patient, will be critical to achieving significant gains in disease outcome. One such opportunity is the use of expression signatures to identify key oncogenic phenotypes that can serve not only as biomarkers but also as a means of identifying therapeutic compounds that might specifically target these phenotypes. Given the potential importance of targeting tumors exhibiting a stem-like phenotype, we have developed an expression signature that reflects common biological aspects of various stem-like characteristics. The Consensus Stemness Ranking (CSR) signature is upregulated in cancer stem cell enriched samples, at advanced tumor stages and is associated with poor prognosis in multiple cancer types. Using two independent computational approaches we utilized the CSR signature to identify clinically useful compounds that could target the CSR phenotype. In vitro assays confirmed selectivity of several predicted compounds including topoisomerase inhibitors and resveratrol towards breast cancer cell lines that exhibit a high-CSR phenotype. Importantly, the CSR signature could predict clinical response of breast cancer patients to a neoadjuvant regimen that included a CSR-specific agent. Collectively, these results suggest therapeutic opportunities to target the CSR phenotype in a relevant cohort of cancer patients. CD133+ and CD133- cells were separated from two glioma xenograft tumors. Both CD133+ and CD133- glioma cells were cultured in serum-free media for 48 hours in the presence of absence of laminin.

Project description:MEFs were grown from WT and PDPN-deficient mouse embryos and gene expression was analyzed. The aim was to determine whether a lack of PDPN caused significant global changes in gene expression in primary fibroblasts. Here, we performed a microarray on WT and PDPN-deficient mouse embryonic fibroblasts to determine whether there were signficiant underlying changes in gene expression. Two replicates each of WT and PDPN KO MEFs from C57BL6/J mice

Project description:As many other tumors, a subset of gliobastoma is thought to be maintained by a restricted population of cancer cells, stem-like cells that express CD133 transmembrane protein. Expression levels of CD133 gene has been linked to a poor prognostic molecular subgroup and is not overexpressed by the PDGF-driven proneural group. Thus, the significance of CD133+ cells for gliomagenesis of the proneural group is undetermined. In addition, the role of the CD133 protein remains elusive and controversial, which results from the difficult isolation of CD133+ cells that has largely relied on the use of antibodies to ill-defined glycosylated epitopes of CD133. Here, we used a knockin lacZ reporter mouse, Prom1lacZ/+, to track Prom1+ cells in the brain and found that Prom1 (prominin1, murine CD133 homologue) is expressed by cells that co-express markers characteristic of neuronal, glial and vascular lineage phenotype. In proneural tumors derived from injection of RCAS-PDGF into the brain of tv-a;Ink4a-Arf-/- Prom1lacZ/+ mice, Prom1+ cells co-express markers for astrocytes and endothelial cells. Therefore, we characterize the tumor propagation in a murine model and found that the mice co-transplanted with Prom1 endothelium and proneural tumor spheres cells had significant tumor burden and vascular proliferation (angiogenesis). Specific genes in Prom1 endothelium are identified that code for endothelial signaling modulators that most likely support proneural tumor progression and can be potential targets for anti-angiogenic therapy. Cells were sorted via FACS to obtain a population of CD31+CD133- cells and a population of CD31+CD133+ cells. Total RNA was extracted from each population and gene expression was assayed on Affymetrix Mouse 430 2.0 arrays with one array per cell population.
