Project description:This SuperSeries is composed of the following subset Series: GSE23169: Transcriptional profiling of Ramos germinal center B cells GSE23170: ChIP-on-chip experiment from Ramos cells to analyze genome-wide CRTC2 binding sites in germinal center B cells Refer to individual Series
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:ChIP-on-chip experiment from Ramos cells to analyze genome-wide CRTC2 binding sites in germinal center B cells. The goal was to combine information from our ChIP-on-chip and expression array analyses to compile a list of CRTC2 target genes.
Project description:ChIP-on-chip experiment from Ramos cells to analyze genome-wide CRTC2 binding sites in germinal center B cells. The goal was to combine information from our ChIP-on-chip and expression array analyses to compile a list of CRTC2 target genes. CRTC2 was immunoprecipitated from sheared chromatin isolated from untreated Ramos cells using 2 antibodies which recognize distinct epitopes on the CRTC2 protein. Immunoprecipitates were compared to total input chromatin. 2 biological replicates were performed for each antibody.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression. Two-condition experiment, Normoxic MSCs vs. Hypoxic MSCs.
Project description:Transcriptional profiling of Ramos germinal center B cells, comparing untreated cells to cells treated with etoposide, and untreated cells to cells treated with anti-IgM. Both treatments, engagement of the B-cell receptor with anti-IgM and induction of DNA double-strand breaks with etoposide, result in phosphorylation and cytoplasmic sequestration of CRTC2, and cause downregulation of known CRTC2 target gene TCL1. The goal of these experiments was to determine what other genes are downregulated by both of these CRTC2-inactivating treatments, and to compare this list to the list of genes whose promoters were occupied by CRTC2 in our ChIP-on-chip assay.

Untreated samples vs. etoposide-treated samples, untreated samples vs. anti-IgM-treated samples. Each comparison was done in biological triplicate plus dye swap.
