Expression data from J82 side population and non-side population cells

Project description:Subpopulations of highly tumorigenic, drug resistant cancer stem-like cells play a key role in cancer recurrence and progression. Surprisingly, these aggressive cells can arise repeatedly de novo from bulk tumor cells independently of mutational events. We investigated whether transition to and from a cancer stem-like state is associated with epigenetic alterations, such as DNA methylation and chromatin accessibility. By Hoechst dye staining and FACS analysis, side population (SP) and non-side population cells were sorted from J82 cells. AcceSssIble assay by Infinium EPIC BeadArray platform was used to identify potential epigenetic driver genes in the process of SP /NSP phenotype plasticity. Genes with differential accessible promoter regions were overlapped with genes differentially expressed by HuEx array analysis. Oncomine and Basespace were adopted to explore the clinical relevance of the target genes.

Single cell RNA sequencing data of Side Population and Non-Side Population tumor cells from a mouse model of undifferentiated pleomorphic sarcoma

Project description:We report the application of single-cell RNA sequencing data on Side Population (SP) cells and their Non-Side Population (NSP) counterparts in a mouse model of undifferentiated pleomorphic sarcoma (UPS). SP cells exhibit tumor propagting cell properties characterized by enhanced tumorigenicity and self-renewal potential. The purpose of this experiment is to investigate cellular heterogeneity at the gene expression level in UPS tumors and lineage relationships between different subpopulation of tumor cells. We generated the gene expression profiles of individual cells in the SP and NSP compartments of mouse UPS.

Expression data from HTR-8/Svneo side population (SP) and non-side population (NSP) cells

Project description:Immature cell populations, including stem cells and progenitor cells, can be found in M-bM-^@M-^\side-population (SP)M-bM-^@M-^] cells. Although SP cells isolated from some adult tissues have been reported elsewhere, isolation and characterization of human trophoblast SP cells remained to be reported. We used microarrays to detail the global program of gene expression underlying cell differentiation and identified up-regulated genes of SP HTR-8/SVneo SP cells or NSP cells were isolated using a FACS Vantage fluorescence-activated cell sorter (BD Bioscience, San Jose, California) using dual wavelength analysis (blue, 424 - 444nm; red 675 nm) after excitation with 350 nm UV light. PI-positive dead cells were excluded from the analysis. Sorted SP and NSP cells' RNA had been analyzed by microarray analysis.

Expression data from HTR-8/Svneo side population (SP) and non-side population (NSP) cells

Project description:Immature cell populations, including stem cells and progenitor cells, can be found in “side-population (SP)” cells. Although SP cells isolated from some adult tissues have been reported elsewhere, isolation and characterization of human trophoblast SP cells remained to be reported. We used microarrays to detail the global program of gene expression underlying cell differentiation and identified up-regulated genes of SP cells. HTR-8/SVneo SP cells or NSP cells were isolated using a cell sorter for RNA extraction and hybridization on Affymetrix microarrays. To obtain many SP or NSP cells, we cultured a large amount of HTR-8/SVneo cells (1×10^7 cells). The cells were labeled with 2.5µg/ml Hoechst 33342 dye (Molecular Probes, Eugene, OR) for 120 minutes at 37 ℃, either alone or in combination with 50 µmol/L verapamil (Sigma-Aldrich, ST Louis, MO). Finally, the cells were then passed through EPICS ALTRA HyPerSort (Beckman Coulter, Fullerton, CA) using dual wavelength analysis (blue, 424-444 nm; red, 675 nm) after excitation with 350 nm UV light.
