Transcriptional profiling of Ramos germinal center B cells

ABSTRACT: 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.

ChIP-on-chip experiment from Ramos cells to analyze genome-wide CRTC2 binding sites in germinal center B cells

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.

Effect of expression of ZEBRA on gene expression during Ramos cells

Project description:EBV immediate early protein ZEBRA was corroborated to interact with Pax5 which controls the fate of B cells. Ramos cells were infected with ZEBRA-expression lentivirus and positively infected cells were sorted, which were named Ramos-Lv-ZEBRA.

Effect of hypoxia and treatment with cyclosporine A on chemotaxis of RAMOS B cells

Project description:To investigate the effect of changes in oxygen tension and treatment with cyclosporine A on the chemotactic migration of B cells, we grew RAMOS B cells at 19% and 1% oxygen levels, and at 19% and 1% oxygen levels after treatment with cyclosporine A. We then performed RNA-seq on these RAMOS B cells and subequently gene expression profiling analysis on this RNA-seq data.
