Comparing the transcriptome of SP cells with that of non-SP cells in rainbow trout

ABSTRACT: In rainbow trout, type A spermatogonia can be split into SP cells and non-SP cells by the ability to exclude Hoechst 33342 dye (H33342). The H33342 fluorescence of SP cells are lower than that of non-SP cells, after H33342 staining. To investigate whether SP cells were transcriptomically distinct from non-SP cells, we compared the transcriptome of these cells. We used fluorescence-activated cell sorting (FACS) to isolate SP cells and non-SP cells from the type A spermatogonia in rainbow trout.

Comparing the transcriptome of SP cells with that of non-SP cells in rainbow trout

Project description:In rainbow trout, type A spermatogonia can be split into SP cells and non-SP cells by the ability to exclude Hoechst 33342 dye (H33342). The H33342 fluorescence of SP cells are lower than that of non-SP cells, after H33342 staining. To investigate whether SP cells were transcriptomically distinct from non-SP cells, we compared the transcriptome of these cells. We used fluorescence-activated cell sorting (FACS) to isolate SP cells and non-SP cells from the type A spermatogonia in rainbow trout. To compensate unavailability of genetically uniform rainbow trout in independent sampling, SP cells and non-SP cells were collected at 3 times from 3 different parental fish groups. This experimental design allowed us to estimate effects specific to each parental fish genotype on mRNA expression in SP cells by a statistical modeling and to exclude the effects in subsequent analysis.

Expression data from SP and non-SP sorted anti-EpCAM treated A549 cells

Project description:Targeted therapies against cancer stem cells, which are enriched in side populations (SP), involves interruption of Wnt-signalling. Furthermore, EpCAM is a SP marker and modulator of Wnt-signalling. Therefore, the effects of an anti-EpCAM treatment on SP-cells and WNT/Î²-catenin signalling was studied. SP of the human lung adenocarcinoma cell line A549 was obtained by fluorescence activated cell sorting and whole genome scans helped to define their molecular phenotype after anti-EpCAM antibody treatment. Anti-EpCAM treated and untreated A549 cells were subjected to Hoechst 33342 dye exclusion assay and sorted to SP and non-SP fractions by FACS. Three biological replicates.

Expression data from SP and non-SP sorted anti-EpCAM treated A2C12 cells

Project description:Targeted therapies against cancer stem cells which are enriched in side populations (SP) involves interruption of Wnt-signalling. Furthermore, EpCAM is a SP marker and modulator of Wnt-signalling. Therefore, the effects of an anti-EpCAM treatment on SP-cells and WNT/M-NM-2-catenin signalling was studied. SP of the murine lung adenocarcinoma cell line A2C12 was obtained by fluorescence activated cell sorting and whole genome scans helped to define their molecular phenotype after anti-EpCAM antibody treatment. Anti-EpCAM treated and untreated A2C12 cells were subjected to Hoechst 33342 dye exclusion assay and sorted to SP and non-SP fractions by FACS. Three biological replicates.

Transcription profiling of zebrafish kidney side population (SP) cells

Project description:Side population (SP) cells are identified based on their capacity to efflux of the fluorescent dye Hoechst 33342, and are enriched for hematopoietic stem cells (HSCs) in mammalian bone marrow. We recently demonstrated that SP cells were present in the teleost kidney, the main hematopoietic organ in teleosts, and were enriched for HSCs. In this analysis, to identify the regulated genes in teleost HSCs, gene expression analysis of zebrafish kidney SP cells were performed using the GeneChip Zebrafish Genome Array. Experiment Overall Design: Based on their Hoechst fluorescence intensity, lymphoid cells (FS-low, SS-low) from zebrafish kidney were subdivided into SP and MP populations (referred to as âzSPâ and âzMPâ). To minimize the biological variability, 20 zebrafish were used for 3 independent cell sorting experiments and lysates from these 3 experiments were pooled by cell type. Each RNA sample was split into two aliquots and used for amplification, labeling, and hybridization to independent arrays.

Gene expression in IGROV1 SP and non-SP cells

Project description:Side populations have recently been identified in ovarian cancers and may play an important role in post treatment relapse and resistance to chemotherapeutic drugs. In this study, we aimed to identify the differential expression between IGROV1 SP and NSP on Affymetrix HG-U133plus2 microarrays. We found ovarian tumour SP cells frequently over-express the multi-drug resistance associated P-glycoprotein (ABCB1) by Rank Product (FDR<0.05), and by geneset enrichment analysis, embryonic stem cell-associated ‘NOS’ signature (Notch/Oct4/Sox2 regulated genes) and Polycomb Repressive Complex 2 (PRC2) genes were over-expressed, while PRC2-repressed target genes were significantly under-expressed in the SP from ovarian cell lines compared to non-SP (FDR<10-4). Cells were isolated using Hoechst 33342 cell sorting without other treatment. The experiment was carried out in triplicates: 3 SP samples and 3 non-SP samples

Identification of type A spermatogonia specific transcriptome in rainbow trout immature testis

Project description:To identify the transcripts preferentially expressed in type A spermatogonia in rainbow trout immature testis, we compared the transcriptome between type A spermatogonia and testicular somatic cells by microarry analysis. We used fluorescence-activated cell sorting (FACS) to isolate type A spermatogonia or testicular somatic cells from the fishes carrying the transgene, pvasa-GFP, which expresses GFP in spermatogonia.
