To characterize human bone marrow plasma cells that express or lack CD19 on a molecular level, we compared the global gene expression of primary CD38high/CD138+ plasma cells with or without CD19 expression.
A unique population of IgG-expressing plasma cells lacking CD19 is enriched in human bone marrow.

View SamplesGlioblastomas (GBMs) are divided into CpG Island Methylator Phenotype (CIMP) and non-CIMP tumors. Non-CIMP GBMs derive from cells with non-disjunction of chromosome (chr7) and chromosome 10 (chr10), resulting in chr7 gain and chr10 loss, while CIMP GBMs have mutations in isocitrate dehydrogenase 1 or 2 (IDH1/2). Gain of chr7 is largely driven by PDGFA, but other genes on chr7 are likely to contribute to fitness gains and aggressiveness of these GBMs. We computationally investigated genes on chr7 whose gene expression correlated with survival, identifying HOXA5 as a potential driver of proneural gliomagenesis. Using a combination of human GBM cells and mouse PDGF-driven gliomas, we showed that HOXA5 drives increased proliferation and radiation resistance in culture and in vivo. These phenotypes appear to be in part due to effects on p53 and other apoptosis-related genes.
Increased <i>HOXA5</i> expression provides a selective advantage for gain of whole chromosome 7 in IDH wild-type glioblastoma.

View SamplesWe found that 5-Aza-dC/decitabine induces various prosurvival pathways (JAK-STAT-, NFkB-, MEK/ERK- and PI3K/AKTpathway) in cHL cell lines. Inhibition of these pathways with specific small molecular weight inhibitors potentiates the antitumor effect of 5-Aza-dC.

View SamplesInnate immune responses of plant cells confer the first line of defence against pathogens. Signals generated by activated receptors are integrated inside the cell and converge on transcriptional programmes in the nucleus. The Arabidopsis Toll-related intracellular receptor RPS4 operates inside nuclei to trigger resistance to Pseudomonas bacteria expressing AvrRps4 and defence gene reprogramming through the stress response regulator, EDS1.
Arabidopsis TNL-WRKY domain receptor RRS1 contributes to temperature-conditioned RPS4 auto-immunity.

View SamplesWe compared gene expression profiles of a human CD4+ T-cell line 24 h after infection with a cell line of the same origin permanently releasing SIVmac251/32H. A new knowledge-based-network approach (Inter-Chain-Finder) was used to identify subnetworks leading to resistance to SIV-induced cell death. Notably, the method can identify not only differentially-expressed key hub genes but also non-differentially expressed, critical, hidden regulators.
