ProteomicsThe value of subcellular fractionation for protein identification in a B-cell line (Ramos)
Integrated in the Chromosomic-centric Human Proteome Project (C-HPP), a lymphocytic B-cell line (Ramos) was selected as a model of B-cells. We performed a subfractionation strategy (in triplicate) for the extraction of proteins from 4 different fractions (cytoplasm, CYT; organella, ORG; membrane, MB...

ProteomicsQuantitative Proteomics Identifies Protein Tyrosine Phosphatase 1B as Modulator of B Cell Antigen Receptor Signaling
B cell antigen receptor (BCR) signaling is initiated by protein kinases and limited by counteracting phosphatases that currently are less well studied in their regulation of BCR signaling. We here used the B cell line Ramos to identify and quantify human B cell signaling components. Specifically, a ...

TranscriptomicsTranscriptional profiling of Ramos germinal center B cells
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, resul...

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

ProteomicsMHC Peptidomics: HLA-B*27 vs Mamu-B*08
Indian rhesus macaques are arguably the most reliable animal models in AIDS research. In this species the MHC class I allele Mamu-B*08, among others, is associated with elite control of SIV replication. A similar scenario is observed in humans where the expression of HLA-B*27 or HLA-B*57 has been li...

ProteomicsCyclosporine A Modulates LSP1 Protein Levels in Human B Cells to Attenuate B Cell Migration at Low O2 Levels
Coordinated migration of B cells within and between secondary lymphoid tissues is required for robust antibody responses to infection or vaccination. Secondary lymphoid tissues normally expose B cells to a low O2 (hypoxic) environment. Recently, we have shown that human B cell migration is modulated...

TranscriptomicsTranscription profiling of human B-cell lymphoma cell lines treated with motexafin gadolinium and zinc reveals induced oxidative stress responses and apoptosis
There is an emerging appreciation of the importance of zinc in regulating cancer cell growth and proliferation. Recently, we showed that the anticancer agent motexafin gadolinium (MGd) disrupted zinc metabolism in A549 lung cancer cells, leading, in the presence of exogenous zinc, to cell death. Her...
