Project description:To assess whether genes associated with BH4Ds are more or less sensitive than genes associated with sharp H3K4me3 peaks to perturbation of H3K4me3 levels, we performed RNA-Seq experiment from Jurkat cells treated with DMSO or with 2-(4-methylphenyl)-1,2-benzisothiazol-3(2H)-one (PBIT), a specific inhibitor of JARID1 family of H3K4me3 demethylases, also known as KDM5 (Blair et al. 2011; Sayegh et al. 2013).

Project description:CHOPPER (Chemical enrichment of protease site with purchasable, elutable reagents, an N terminomics method) with DMSO-treated Jurkat cells
Project description:1.0 – 1.3 x 10e8 proliferating Jurkat cells at a density of about 1-1.5 x 10e6 cells/mL were employed per sample. Cells were incubated with 0.5mM DMOG (Cayman Chemical Company, 71210) or an equivalent volume of Dimethyl Sulfoxide (DMSO) (vehicle, Merck 1.02950.0500). The DMSO concentration in the medium was 0.023% v/v. Cells were irradiated or not with 254 nm UV light and subjected to eRIC or RIC to determine the RNA-bound proteome. Data correspond to two biologically independent experiments.
Project description:To determine changes of gene expression in human CD4+ T cells (Jurkat) infected with HIV-1 and treated with digoxin. Cells were infected (MOI 0.01) with a single cycle HIV-1 delta env expressing GFP and pseudotyoed with VSV-G in the presence of 400nM digoxin or DMSO. Cells were harvested 36 hours post-infection and processed for RNAseq
