TranscriptomicsTranscription profiling of human monocyte derived dendritic cells treated with DC-SIGN initiates an immature dendritic cell phenotype triggering Rho activation that is utilised by HIV-1
DC-SIGN is a C-type lectin expressed by dendritic cells (DCs) that binds HIV-1, sequestering it within multivesicular bodies to facilitate transmission to CD4+ T cells. Here we characterize the molecular basis of signalling through DC-SIGN by large-scale gene expression profiling and phosphoproteome...

ProteomicsPosttranslational modification of the RHO of plants protein RACB by phosphorylation and cross-kingdom conserved ubiquitination
Small RHO-type G-proteins act as signaling hubs and master regulators of polarity in eukaryotic cells. Their activity is tightly controlled, as defective RHO signaling leads to aberrant growth and developmental defects. Two major pathways regulate G-protein activity: canonical switching of the nucle...

TranscriptomicsRho and NusG suppress pervasive antisense transcription in Escherichia coli [ChIP-chip].
Despite the prevalence of antisense transcripts in bacterial transcriptomes, little is known about how their synthesis is controlled. We report that a major function of the Escherichia coli termination factor Rho and its co-factor NusG is suppression of ubiquitous antisense transcription genome-wide...

TranscriptomicsRho directs widespread termination of intragenic and stable RNA transcription
The transcription termination factor Rho is a global regulator of RNA polymerase (RNAP). Although individual Rho-dependent terminators have been studied extensively, less is known about the sites of RNAP regulation by Rho on a genome-wide scale. Using chromatin immunoprecipitation and microarrays (...

TranscriptomicsTranscription profiling of human normal and RhoA immortal cells
Rho family small GTPases serve as molecular switches in the regulation of diverse cellular functions including actin cytoskeleton remodeling, cell migration, gene transcription, and cell proliferation. Importantly, Rho overexpression is frequently seen in many carcinomas. However, published studies...

TranscriptomicsExpression values from wild-type retinas and retinas with a mutant Rhodopsin transgene (Tg(RHO P347S)) with and without Endothelin-2 (EDN2)
Expression of the Endothelin-2 (Edn2) mRNA is greatly increased in the photoreceptors (PRs) of mouse models of inherited PR degeneration. To identify retinasl gene whose expression is directly or indirectly regulated by EDN2 in the presence of the Tg(RHO P347S) mutant allele, we defined mRNAs that w...

TranscriptomicsTranscription profiling of human CD34+ cells and treatment with UTP and CXCL12
Homing and engraftment of hematopoietic stem cells (HSCs) to the bone marrow (BM) involve a complex interplay between chemokines, cytokines, and non-peptide molecules. Extracellular nucleotides and their cognate P2 receptors are emerging as key-factors of inflammation and related chemotactic respons...
