PIM kinases facilitate lentiviral evasion from SAMHD1 restriction via Vpx phosphorylation

ABSTRACT: Proteomic analysis revealed potential phospho-acceptor sites within Vpx by PIM3. HEK293 cells were transfected with plasmid vector encoding Vpx together with either empty vector or PIM3. Immunoprecipitated Vpx was subjected to liquid chromatography tandem-mass spectrometry.

Lentiviruses have evolved to acquire an auxiliary protein Vpx to counteract the intrinsic host restriction factor SAMHD1. Although Vpx is phosphorylated, it remains unclear whether such phosphorylation indeed regulates its activity toward SAMHD1. Here we identify the PIM family of serine/threonine protein kinases as the factors responsible for the phosphorylation of Vpx and the promotion of Vpx-mediated SAMHD1 counteraction. Integrated proteomics and subsequent functional analysis reveal that PI ...[more]

iCLIP Analysis of WT, phospho-defective, and phospho-mimicking mutants of mouse Nucleolin in iKras PDAC cells

Project description:This experiment aimed to identify Nucleolin (Ncl) binding sites on a transcriptome-wide scale, by performing iCLIP in mouse iKras PDAC cells (Ying et al., 2012) transiently transfected with a mammalian expression construct encoding a wild-type (WT) myc-Ncl, a phospho-defective mutant in which S28, S34, S40, and S41 residues were mutated to A, or a phospho-mimicking mutant with these residues mutated to D. Cells transfected with an empty vector (myc-pRK5-DEST) were used as controls in the experiment.

The Wilms' tumour 1 transcription factor regulates epigenetic states via DNA methyltransferase 3A

Project description:The Wilms' tumour 1 transcription factor regulates epigenetic states via DNA methyltransferase 3A. The data consists of two Nimblegen promoter/CpG island microarrays hybridized with MCIP DNA immunoprecipitated from either a HEK293-derived cell line expressing a heterologous WT1 cDNA (W210) or a control cell line containing the expression vector (IP100), both hybridized against input DNA.

EWS-FLI1-transfection of HEK293

Project description:Response of HEK293-cells after transfection with EWS-FLI1. HEK293 cells were transfected with the expression vector pIRES2-EGFP containing type I EWS-FLI1 or empty control vector. For transient transfection standard DEAE dextran method was used and RNA was isolated 48h post transfection. For stable transfection cells were transfected using FuGENE 6 (Roche, Mannheim, Germany) and cells were selected with 400 ug/mL G418. DNA-microarray analysis was performed using Affymetrix HG-U133A microarrays.(see Staege et al. Cancer Res. 2004) Keywords = HEK293 Keywords = EWS-FLI1 Keywords = Ewing family tumors Keywords: other

HCaRG vs NEO

Project description:Summary: HEK293 cells were transfected with control plasmid (pcDNA1/Neo; Invitrogen) or with the plasmid encoding HCaRG by a standard calcium phosphate co-precipitation method. The clones expressing the highest levels of HCaRG, HCaRG clone 8 and 9 were used in this experiment, while clone transfected with vector alone, Neo clone, served as control. Stable transfectants were synchronized and grown in the presence of 10% FBS for 48 h. Total RNAs were purified with the mini RNeasy kit (Qiagen). Keywords: parallel sample

The target genes of transcript factor ZNF191

Project description:Transcriptional profiling of human embryo kidney cells comparing control HEK293 transfected with empty vectors cells with HEK293 cells transfected with pcDNA3-ZNF191 (or ZNF191 siRNA vector). We searched for early ZNF191 target genes by using a transient overexpression and knockdown strategy in the human embryo kidney (HEK293) cells. A table of gene targets of transcription factor ZNF191 commonly identified by both strategies is appended below as a supplementary file.

HEK293T cells were transfected with Flag-tagged NLRP3 treated with or without nigericin (10 μM, 1 h).

Project description:In order to identificate NLRP3 acetylation, we utilized an acetylproteomic approach to identify the acetylation sites within NLRP3. We first reconstituted the NLRP3 inflammasome in HEK293T cells by co-transfected with plasmids encoding NLRP3, ASC, Caspase-1 and Pro-IL-1β, then stimulated the genetically modified cells with nigericin.Flag-tagged NLRP3 was immunoprecipitated and analyzed by liquid chromatography-mass spectrometry.

Expression profile of HEK293 cells stably transfected with PRL-1 (PTP4A1) or empty pcDNA4 vector (control)

Project description:The multifunctional protein tyrosine phosphatase PRL-1 (Gene Symbol: PTP4A1) has been identified as an important oncogene with roles in promoting cell proliferation, survival, migration, invasion, and metastasis. However, little is currently known about the signaling pathways through which it mediates its effects. We used Affymetrix Human Genome U133 Plus 2.0 arrays to examine the global molecular changes of gene expression occurring in response to stable PRL-1 overexpression in human embryonic kidney 293 (HEK293) cells. Total RNA was extracted from triplicate cultures of HEK293 cells stably overexpressing PRL-1 (HEK293-PRL-1) and HEK293 cells stably transfected with empty pcDNA4 vector (HEK293-Vector). Samples were hybridized to Affymetrix HG U133 Plus 2.0 microarrays (1 array per sample for a total of 6 arrays). One of the arrays hybridized with a PRL-1 transfected sample was excluded after qRT-PCR demonstrated that this sample did not exhibit increased PRL-1 expression over the level of the empty vector controls. The remaining 2 HEK293-PRL-1 samples both expressed PRL-1 at least 2-fold higher than any of the 3 empty vector controls.
