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

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.

Click here to queue conversion of this dataset's submitted spectrum files to open formats (e.g. mzML). This process may take some time.

When complete, the converted files will be available in the "ccms_peak" subdirectory of the dataset's FTP space (accessible via the "FTP Download" link to the right).
Number of distinct conditions across all analyses (original submission and reanalyses) associated with this dataset.

Distinct condition labels are counted across all files submitted in the "Metadata" category having a "Condition" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct biological replicates across all analyses (original submission and reanalyses) associated with this dataset.

Distinct replicate labels are counted across all files submitted in the "Metadata" category having a "BioReplicate" or "Replicate" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct technical replicates across all analyses (original submission and reanalyses) associated with this dataset.

The technical replicate count is defined as the maximum number of times any one distinct combination of condition and biological replicate was analyzed across all files submitted in the "Metadata" category. In the case of fractionated experiments, only the first fraction is considered.

"N/A" means no results of this type were submitted.
Originally identified proteins that were automatically remapped by MassIVE to proteins in the SwissProt human reference database.

"N/A" means no results of this type were submitted.
Number of distinct protein accessions reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct unmodified peptide sequences reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct peptide sequences (including modified variants or peptidoforms) reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Total number of peptide-spectrum matches (i.e. spectrum identifications) reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct proteins quantified across all analyses (original submission and reanalyses) associated with this dataset.

Distinct protein accessions are counted across all files submitted in the "Statistical Analysis of Quantified Analytes" category having a "Protein" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct proteins found to be differentially abundant in at least one comparison across all analyses (original submission and reanalyses) associated with this dataset.

A protein is differentially abundant if its change in abundance across conditions is found to be statistically significant with an adjusted p-value <= 0.05 and lists no issues associated with statistical tests for differential abundance.

Distinct protein accessions are counted across all files submitted in the "Statistical Analysis of Quantified Analytes" category having a "Protein" column in this dataset.

"N/A" means no results of this type were submitted.
This dataset may not contain all raw spectra data as originally deposited in PRIDE. It has been imported to MassIVE for reanalysis purposes, so its spectra data here may consist solely of processed peak lists suitable for reanalysis with most software.
