A novel inducible retroviral expression system for StrepHA-tandem affinity purification mass-spectrometry-based proteomics

ABSTRACT: Tandem-affinity purification mass spectrometry using the streptavidin-hemagglutinin (SH)-tag has been successfully employed to map signaling networks in several large-scale studies. However its application has so far been restricted to the small number of Flp/FRT-recombination competent cell lines. We present pRSHIC, a novel retroviral, doxycycline-inducible Tet-On vector system suitable for expression of SH-tagged target proteins in a wide range of human and mouse cell systems. The additional feature of concomitant reporter fluorophore expression makes pRSHIC a valuable tool for a diverse set of phenotypic analyses beyond TAP-MS experiments. The dataset demonstrates the application of pRSHIC for TAP-MS analysis of two showcase bait proteins involved in cancer cell proliferation as well as cell death induction and identified novel high- confidence interacting proteins with possible pharmacological intervention potential.

ChIP-seq analysis of human neuroblastoma cell lines

Project description:The aim of the experiment is to identify genome wide binding sites for the transcription factor MYCN in MYCN non-amplified and MYCN amplified human neuroblastoma cell lines. Datasets are presented for the ChIP-seq analysis in the tetracycline inducible cell line SH-SY5Y-MYCN (SH-SY5Y/6TR(EU)/pTrex-Dest-30/MYCN), derivative of the parental cell line SH-SY5Y; for noninduced cells and for 24 and 48 hours of Tet induction. Analysis for patinet matched MYCN amplified cell lines SMS-KCN and SMS-KCNR is also included.

Transcription profiling of mouse induced pluripotent stem cells

Project description:We have previously shown that pluripotent stem cells are induced from mouse fibroblasts by retroviral introduction of Oct3/4, Sox2, c-Myc and Klf4, and subsequent selection for Fbx15 expression. These iPS (induced pluripotent stem) cells are similar to embryonic stem (ES) cells in morphology, proliferation and teratoma formation. Fbx15-iPS cells, however, are different in gene expression and DNA methylation patterns and fail to produce adult chimeras. Here we show that selection for Nanog results in germ-line competent iPS cells, with more ES cell-like gene expression and DNA methylation patterns. The four transgenes were strongly silenced. We obtained adult chimeras from seven Nanog-iPS clones, with one clone transmitted through the germ-line to the next generation. Approximately 20% of the offspring developed tumors, where c-Myc transgene was reactivated. Thus iPS cells competent for germ-line chimeras can be obtained from fibroblasts, but retroviral introduction of c-Myc should be avoided for clinical application. Experiment Overall Design: Total RNA from Fbx15-null MEF (duplicate), Fbx15-null ES cells (duplicate), Fbx15-iPS cells (clone MEF4-7, duplicate), or Nanog-iPS cells (clones 20D -2, 16, 17, and 18) were labeled with Cy3. Samples were hybridized to a Mouse Oligo Microarray (Agilent) according to the manufacturerâs protocol. Arrays were scanned with a G2565BA Microarray Scanner System (Agilent). Data were analyzed using GeneSprings GX software (Agilent). We excluded genes whose value fluctuated more than 2-fold between duplicated analyses.

MicroRNA profiling by array of human MCF-7 breast cancer cells with ER-beta tagged at the C-terminal or N-terminal and treated with 17-beta-estradiol

Project description:Human estrogen-responsive breast cancer cell line MCF-7 TET Off (MCF-7 wt) were used to produce stable clones expressing ER-beta tagged with TAP-tag respectively at the C-term and at the N-term (C-TAP-ER-beta and N-TAP-ER-beta) or expressing ER-alpha tagged (C-TAP-ER-alpha) as previously described.(C-TAP-ER-beta, N-TAP-ER-beta, C-TAP-ER-alpha) were treated with 10nM of17-beta-estradiol, or vehicle (ETOH). miRNA expression was analyzed on total RNA extracted before or after 6, 12, 24, and 72 hours hormonal stimulation. Total RNA was fluorescently labelled, amplified in triplicate, to be, than, pooled for the Hybridization.Each pool, were hybridized for 18 hours on Illumina v2 MicroRNA Expression BeadChips, and after scanning, analysis was performed with GenomeStudio v.2010.1 software, for quality control and miRNA expression analysis.

Transcription profiling by array of human MCF-7 cells with ER-beta tagged with TAP-tag at the C-term or N-term or expressing ER-alpha tagged

Project description:MCF-7 TET Off cells (MCF-7 wt) were used to produce stable clones expressing ER-beta tagged with TAP-tag respectively at the C-term and at the N-term (C-TAP-ER-beta and N-TAP-ER-beta) or expressing ER-alpha tagged (C-TAP-ER-alpha). All were grown in Dulbecco's modified Eagle's medium (DMEM). Then cells were lysed and RNA extracted were pooled. For mRNA expression profiling, 500 ng total RNA were reverse transcribed and used for synthesis of cDNA and biotinylated cRNA. Finally cRNA were hybridized for 18 hours on Illumina HumanHT-12 v3.0 BeadChips and after scanning, data analysis was performed.
