Stable isotope labeling with amino acids in mouse xenografts.

ABSTRACT: This dataset corresponds to a SILAC analysis in mouse xenografts and in cell culture. We analysed signalling in tumors by means of a method based on stable isotope labeling with amino acids of xenograft tumors by the addition of [(13)C(6)]-lysine into mouse food, and also using a typical SILAC analysis in cell culture. This dataset includes 2 groups of analysis: one, with maxquant file tagged SILAX, corresponding to the xenograft analysis, the other one to SILAC analysis in cell culture. Data were acquired on an LTQ-Orbitrap XL mass spectrometer coupled with an Ultimate 3000 HPLC. Analysis was performed using MaxQuant software (version 1.1.1.36). All MS/MS spectra were searched using Andromeda against a database consisting of a combination of Homo sapiens and Mus musculus CPS databases and 250 classical contaminants. Search was performed allowing the following variable modifications: Oxidation (M) and Phospho (STY). FDR was set at 0.01 for peptides and proteins, and the minimal peptide length was six. Quantification was also performed using standard parameters; we considered only proteins with at least two identified/quantified peptides.

Super-SILAC analysis of human lung primary tumor-derived xenografts LC-MS/MS

Project description:Non-small cell lung cancer (NSCLC) accounts for 85% of lung cancers, and is subdived into 2 major histological subtypes: adenocacinoma (ADC) and squamous cell carcinoma (SCC). Super-SILAC methodology was used to facilitate the quantitative comparisons of human primary tumor-derived xenograft proteomes by high resolution MS analysis. Xeno092 and Xeno441 were ADCs. Xeno 561 and Xeno691 were SCCs. Principal component analysis and supervised t-tests revealed differentially expressed proteins responsible for the classification of the samples according to their distinctive proteomes. These results confirm known differentiators between ADC and SCC subtypes of NSCLC (e.g. a keratin signature, cell adhesion molecules, and metabolism proteins), and reveal novel candidates that may be useful to classify and treat NSCLC tumors. The raw files were analyzed by MaxQuant (version 1.3.0.5). Peaks were searched against the UniProt human database (released Jul, 2012; http://www.uniprot.org) using the Andromeda search engine included in MaxQuant. Two miscleavages were allowed and at least six amino acids per identified peptide were required. The false discovery rate for peptides and proteins was set at 0.01. 'Match between runs' option was selected within a time window of 2 min. A minimum ratio count of 2 was used for quantification of SILAC pairs. Further data analysis was performed in Perseus.

Proteomic portrait of human breast cancer progression identifies novel prognostic markers

Project description:Triplicate analysis of eleven breast cancer cell lines, each separated to 12 offgel fractions. Proteomes were quantified relative to heavy SILAC-labeled MCF7 cells that served as a spike-in standard. In this study, we used system-wide analysis of breast cancer proteomes to identify proteins that are associated with the progression of ER(-) tumors. Our two-step approach included an initial deep analysis of cultured cells that were obtained from tumors of defined breast cancer stages, followed by a validation set using human breast tumors. Using high-resolution mass spectrometry and quantification by Stable Isotope Labeling with Amino Acids in Cell Culture (SILAC), we identified 8,750 proteins and quantified 7,800 of them. A stage-specific signature was extracted and validated by mass spectrometry and immunohistochemistry on tissue microarrays. Data analysis: Raw MS files from the LTQ-Orbitrap were analyzed by MaxQuant (version 1.1.1.9). MS/MS spectra were searched against the decoy IPI-human database version 3.68 containing both forward and reverse protein sequences by the Andromeda search engine. For identification, the false discovery rate (FDR) was set to 0.01 on the protein and on the peptide levels.

Quantitative proteomic analysis of Murine Norovirus infected BV-2 cells (v2)

Project description:SILAC-labelling analysis of murine BV-2 cells infected at high multiplicity of infection (10 TCID50/cell) and harvested at 4h or 9h post-infection. Represents the first quantitative proteomics analysis of norovirus-infected cells. A paired AP-MS dataset investigates the effects of MNV infection on eukaryotic initiation factor (eIF) complex formation with this dataset providing data on the overall abundance of eIF components in infected cells. This is a reanalysis of an earlier dataset (PXD004015) performed in Maxquant (v1.5.5.1).

Xenografted Tumor decellularization provides cell-specific in vitro 3D environment

Project description:In vitro cell culture studies are common in cancer research field, and reliable biomimetic 3D models are needed to ensure physiological relevance. In this manuscript, we hypothesized that decellularized xenograft tumors can serve as an optimal 3D substrate to generate a top-down approach for in vitro tumor modeling. Methods: Multiple tumor cell lines were xenografted and the formed solid tumors were recovered for their decellularization by several techniques and further characterization by histology and proteomics techniques. Selected decellularized tumor xenograft samples were seeded with human triple negative breast cancer (TNBC)c ells and cell behavior was compared among them and with other control 2D and 3D cell culture methods. Results: A soft treatment using Freeze-EDTA-DNAse allows proper decellularization of xenografted tumor samples. Interestingly, proteomic data show that samples decellularized from TMBC xenograft models had different extracellular matrix (ECM) composition compared to the rest of xenograft tumors tested. The in vitro re-cellularization of decellularized ECM (dECM) yields tumor-type specific cell-behavior in TNBC context. Conclusions: Data indicate that dECM derived from xenograft tumors is a feasible substrate for re-seeding purposes, thereby promoting tumor-type specific cell behavior. These data serve as a proof-of-concept for further potential generation of patient-specific in vitro research models.

Substrates of PRSS35 in PLC cells

Project description:Since PRSS35 only exhibited tumor suppressive effects in mice, but not in the cultured cells, we speculated that some factors in the microenvironment are affected by PRSS35. To explore this possibility, we performed SILAC proteomic analysis in conjunction with RNA sequencing to identify secreted proteins that decreased in accumulation, but not in transcription level, in the culture medium of PRSS35 overexpressing PLC cells.

Regulation of gene expression in ALK inhibitor CH5424802-treated NCI-H2228 xenograft tumors

Project description:To clarify the downstream signal pathway of EML4-ALK in NSCLC, we performed Affymetrix GeneChip analysis using ALK inhibitor CH5424802-treated NCI-H2228 xenograft tumors, and comprehensively characterized the gene expression regulated by inhibition of activated ALK. Mice bearing NCI-H2228 cells were orally administered at dose of 0 (vehicle), 4 or 20 mg/kg of CH5424802, and the tumors were collected and lysed at 6 hours post-dose. Total RNA were extracted from xenograft tumors.
