Project description:The cell line "6780" derived from murine T-cell lymphoma was grown in RPMI medium 1640 with 10% FBS/1% penicillin/Streptomycin/1% l-glutamine/50 μM 2-mercaptoethanol. Vector constructs containing a dominant negative mutant of the human TGF-beta receptor type II (pMSCV-TGFBR-IRES-GFP) or an empty vector (pMSCV-IRES-GF) were kindly provided by Martin Eilers Group, IMT, Marburg, Germany. Cells were incubated with retroviruses containing supernatants for 12 h at 32°C in media containing 4 ?g/ml polybrene. Cells then were expanded at 37°C for an additional 48 h, and GFP-expressing cells were purified by flow cytometry on a FACS Vantage (Becton Dickinson).<br><br><br><br>All animal experiments were performed by following the guidelines from Administrative Panel on Laboratory Animal Care at Stanford University (protocol 8144). For transplantation experiment cells were washed once with PBS and 10x106 cells/site were injected subcutaneously (s.c.) into the flank of FVB/N syngeneic mice. Tumor growth was measured by using a caliper. To inactivate MYC expression and to assess for tumor regression, the drinking water was supplemented with 200 μg/ml doxycycline. Tumors were harvested untreated or after 1, 3 and 4 days upon doxycycline treatment, respectively. Total RNA was isolated from snap-frozen tumor tissue using the RNeasy Kit including DNase-I digest (Qiagen, Valencia, USA) following the manufacturer's protocol.
Project description:TÜAB zebrafish were maintained at 28.5 °C in in 1x Danieau solution (58 mM NaCl, 0.7 mM KCl, 0.4 mM MgSO4, 0.6 mM Ca (NO3)2, 5 mM HEPES, pH 7.6, 0.0001 % Methylene blue). Morpholinos (Gene Tools, Philomath, OR) were designed against Danio rerio lin-9 homolog (Genebank accession NM_001044946). The morpholino (MO) sequences were MO-E1 5´-GTTAGTTTTATTACTCACTCTCGTC-3´ and 5-base mismatch morpholino MO-E1mis 5´-GTTACTTTTAATACTGACTGTCCTC-3´. 7 ng of morpholinos were injected into one cell-stage embryos. 20 embryos per condition (MO E1; MO E1mis) were pooled for RNA purification 24 h post fertilization. Using the two color Quick-Amp Labeling Kit (Agilent; 5190-0444) 100 ng of total RNA were used for cDNA synthesis, mRNA amplification and labeling according to manufacturers instructions. Transcriptional profiling was done on a zebrafish oligo array (Agilent; G2519F AMADID 019161) in a 4 x 44K slide format and analyzed as described before.<br>
Project description:U2OS cells were stably transfected with an ecotropic receptor expression plasmid. These cells were infected with retroviruses expressing MIZ-1 or MYC and subsequently superinfected with retroviruses expressing p14ARF. Selection was carried out 48h following superinfection and selected cells were harvested within 1 - 2 passages. For each condition around 2.5x10<superscript6> cells were pooled.<br>Using the two color Quick-Amp labelling kit (Agilent, 5190-0444) 100ng of total RNA were used for cDNA synthesis, aRNA amplification and labelling according to manufacturer's instructions.<br>Transcriptional profiling was done on a whole human genome oligo microarray (Agilent, G4112F, 014850) in a 4x44k slide format.
Project description:U2OS cells were infected with shRNA vector targeting Ark5 or control vector, selected on puromycin for 48hrs, seeded on 5cm dishes at 20% confluency and harvested in triplicate 48hrs later

Project description:We used microarrays to analyze the role of Lin9 in gene expression. Experimental overall design: We prepared MEFs from embyos containing a conditional allele of Lin9 and a CreERT2 transgene. Transcriptional profiles of untreated and 4-OHT-treated MEFs were compared.

Project description:Mice: knock-out of the Miz1 POZ-domain in brain (Miz1DPOZNes) and control mice. The RNA expression in cerebella of of old Miz1 delta POZ mice (1.5 years), old control mice (1.5 years), young Miz1 delta POZ mice (5.5 weeks) and young control mice (5.5 weeks) was compared
