FAN (Factor associated with neutral sphingomyelinase activation) is an adaptor protein that constitutively binds to TNF-R1. Microarray analysis was performed in fibroblasts derived from wild-type or FAN knockout mouse embryos to evaluate the role of FAN in TNF-induced gene expression.
FAN stimulates TNF(alpha)-induced gene expression, leukocyte recruitment, and humoral response.

View SamplesTranscriptome analysis comparing naive, protective and non-protective spleen memory CD8 T lymphocytes were conducted to identify key functions associated with memory CD8-mediated immune protection. Memory CD8 T cells generated in response to influenza or vaccinia infection (Flu-memory and VV-memory) were compared to inflammatory memory cells (TIM) that were generated by peptide in inflammatory context. Gene expression analysis was performed on quiescent and re-stimulated CD8 T cells.

View SamplesNotch3 is a transmembrane receptor which is critically important for the structure and myogenic response of distal arteries, particularly cerebral arteries. After activation of the receptor, the intracellular domain translocates in the nucleus to activate target genes transcription.
Transcriptome analysis for Notch3 target genes identifies Grip2 as a novel regulator of myogenic response in the cerebrovasculature.

View SamplesThe newly identified claudin-low subtype of cancer is believed to represent the most primitive breast malignancies, having arisen from transformation of an early epithelial precursor with inherent stemness properties and metaplastic features. Challenging this hypothesis, we show both in vitro and in vivo that transcription factors inducing epithelial-mesenchymal transition can drive the development of claudin-low tumors from differentiated mammary epithelial cells, by playing a dual role in cell transformation and dedifferentiation.

View SamplesIn response to inflammatory stimulation, dendritic cells (DCs) have a remarkable pattern of differentiation that exhibits specific mechanisms to control the immune response. Here we show that in response to polyriboinosinic:polyribocytidylic acid (poly I:C), DCs mount a specific transcription program during which the growth arrest and DNA damage-inducible protein 34 (GADD34/MyD116), a phosphatase 1 (PP1) cofactor, is expressed. Together with its constitutively active counterpart CReP, GADD34 promotes an extensive dephosphorylation of the translation initiation factor eIF2-alfa in activated DCs. In turn, dephosphorylation of eIF2-alfa prevents the translation inhibition normally associated with cellular stress or detection of cytoplasmic double-stranded RNA. These observations have important implications in linking pathogen detection with the integrated stress responses molecular machinery. The importance of this regulation for DC function is exemplified by the alteration of IFN-beta production or the induction of caspase-3 cleavage upon inhibition of PP1 activity.
