11 human cell lines - Comparative proteomic analysis of eleven common cell lines reveals ubiquitous but varying expression of most proteins
ABSTRACT: Re-submission of raw data from Geiger T et. al., Comparative proteomic analysis of eleven common cell lines reveals ubiquitous but varying expression of most proteins. Mol Cell Proteomics. 2012 Mar;11(3):M111.014050. doi: 10.1074/mcp.M111.014050. Epub 2012 Jan 25.
Deep proteomic analysis of mammalian cell lines would yield an inventory of the building blocks of the most commonly used systems in biological research. Mass spectrometry-based proteomics can identify and quantify proteins in a global and unbiased manner and can highlight the cellular processes that are altered between such systems. We analyzed 11 human cell lines using an LTQ-Orbitrap family mass spectrometer with a "high field" Orbitrap mass analyzer with improved resolution and sequencing sp ...[more]
Project description:A simple HEK293 lysate, with two files containing a putative mycoplasma contamination, and two negative control samples, taken from Geiger etc al. (Mol Cell Proteomics. 2012 Mar;11(3):M111.014050. doi: 10.1074/mcp.M111.014050. Epub 2012 Jan 25.) [PXD002395].
Project description:Frozen tissue specimens from primary breast tumors were collected and profiled using Affymetrix U133 plus 2 expression microarrays. A publication describing the generation of these data is not yet available. However, these data can be used alongside other Affymetrix breast tumour data sets to form large meta-cohorts for breast cancer research, as was done in Lasham et. al. J Natl Cancer Inst. 2012 Jan 18;104(2):133-146. Frozen tumor tissues comprising of >60% tumor cellularity were extracted for total RNA and hybridized on Affymetrix microarrays.
Project description:Genome wide DNA methylation profiling of RKO cells with combination treatments of non-target siRNA or SRCAP siRNA and PBS or 1uM 5-Aza-CdR treatment. The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across 27,578 CpGs in treated RKO cells. Samples included cells under 4 different treatments. The sample treated with non target siRNA and PBS serves as control sample. Bisulphite converted DNA from the 4 samples were hybridised to the Illumina Infinium 27k Human Methylation Beadchip v1.2
Project description:Comparative Dynamic Transcriptome Analysis (cDTA) enables global analysis of newly synthesized RNA as described in Sun et al. Genome Res. 2012 (DOI:10.1101/gr.130161.111) and reveals defects in transcription with much higher sensitivity than conventional steady-state methods. cDTA was carried out as described in Sun et al. Genome Res. 2012 (DOI:10.1101/gr.130161.111), using the S. cerevisiae heterozygous Med17/med17delta strain (Euroscarf) transfected with plasmids pRS315-SRB4 or pRS315-srb4-ts as described in Larivi̬re et al. Nature. 2012 (DOI:10.1038/nature11670), and Y40343-wildtype (Euroscarf) or Med18-FRB-KanMX6 (Euroscarf) strains. Heatshock of SRB4 and srb4-ts strains was applied for 18 or 60 minutes at 37C prior to RNA labeling as described in Sun et al. Genome Res. 2012 (DOI:10.1101/gr.130161.111). To deplete the Med18 subunit from the nucleus, anchor-away experiments were performed by rapamycin treatment (1 ug/ml in 200 mL YPD) for 18 or 60 minutes at 30C prior to RNA labeling as described in Sun et al. Mol. Cell. 2013 (DOI:10.1016/j.molcel.2013.09.010). Data analysis was as described in Sun et al. Genome Res. 2012 (DOI:10.1101/gr.130161.111).
