ProteoRed main objectives are the standardization and quality control of the services offered by their members and thus is a quality label for the users.

To reach these aims seven working groups have been created, including one devoted to the “Standardization of protocols and technologies”.

ProteoRed activities started on September 2005.

A real compromise:Standarization initiatives and ProteoRed

Standards Within ProteoRed Consortium

– Experiment reporting and reproducibility: automatic generation of MIAPE documents (WG3+4)

– Experiment data exchange: PRIDE incorporation into daily pipeline (WG3)

• Proteored contribution to ABRF PRG 2010 study: Determining sample composition and identifying unforeseen problems in otherwise ‘straight-forward’ proteomics analyses (4th quarter of 2009)

WG 1.- Technological development and standardization of protocols

• These contests have been useful to evaluate the performance of the Spanish Proteomics labs and to know if they reached international standards.

• Several different experimental methodologies have been evaluated along these years, including protein identification, phosphoprotein analysis and qualitative proteomics.

• Some of the contests served to incorporate previously unattended methodologies, e.g., phosphoprotein analysis.

• The contests were useful to evaluate new software platforms purchased by ProteoRed, e.g., Phenyx and Peaks Search Engines.

2006: 1) 2DE Standard: testing each lab 2DE Protocols

2)PMF Protein Identification capabilities 2007:

2DE Multicentric assay to study reproducibility of different 2DE procedures (Silver, SYPRO, DIGE)

2008:Multicentric study: Reproducibility of a 2D Differential

Proteomic Experiment

2009-2010: PME-5: ProteoRed Quantitative Proteomics Study.

WG 2.- Samples collection and handling

MIAPE GE, GI, MS and MSI compliant documents, generated by ProteoRed, have been used to report and compare results

+100 MIAPE reports from ProteoRed multicenter experiments (2007-2010) are publicly available through web application (http://www.proteored.org)

1) - Evaluate robustness of a 2D-DIGE workflow on a differential proteomic analysis.

2) - Strict 2DE conditions to allow for Inter-Lab comparison

3) - Comparison of Image Analysis tools

4) – Performance of MS Protein Id.

5) – Comparison with other LC-MS analysis strategies 

6) – Continue to test MIAPE doc. generator through web site

Multi-laboratory assay 2008 : Reproducibility of a Differential Proteomic Experiment

Summary

• Good reproducibility within and across lab• Good reproducibility of differentially expressed proteins

across labs• Supports the ability to validate each others “discoveries”• Demonstrates that across lab quality control schemes are

feasible within routine 2D proteomic facilities• Highlights some areas to emphasise adherence to or

requirement of further protocol definitions

– Experiment reporting and reproducibility: automatic generation of MIAPE documents (WG3+4)

– Experiment data exchange: PRIDE incorporation into daily pipeline (WG3)

• ProteoRed is assuming HUPO STANDARDS.

– Provide to our costumers a MIAPE compliant report attached to the results as a new service quality label

WG3 (bioinformatics support working group) has developed a web system that helps to create MIAPE documents: MIAPE generator tool

Provide a unique standard compliant report

Standard reporting in ProteoRed

First step:

MIAPE generator tool

MIAPE generator tool

MIAPE comparator

• Compare several MIAPE documents (from different experiments), showing previously selected sections.

• Allows to identify differential results caused by a particular protocol step, technology used, db search parameter…

MIAPE repository• You can share your MIAPE reports with other users or get them available for the whole scientific community

• It can help in the reviewing phase of a journal publication process

1. Authors can report their proteomics experiment following MIAPE guidelines using the tool

2. Authors submit it to the journal

a) as part of the Material and Methods section or as Supplementary Information or…

b) …share the report with journal reviewers

3. Journal reviewers easily verify MIAPE-compliance of the experiment by logging in the web tool

Bioinformatics tools

– Virtual2D (http://proteo.cnb.csic.es:8080/virtual2d/): This tool shows a set of proteins according to a 2d gel.

• ProteoRed CNB bioinformatics team (A. Medina, S. Martínez-de-Bartolomé, E. Salazar and M.A. López-García) has developed bioinformatics tools in compliance with PRIDE standard:

. – Protein Information and Knowledge Extractor (PIKE:http://proteo.cnb.csic.es:8080/pike): This tool retrieves from the Internet, biological information regarding to a set of proteins. It can create a new PRIDE file from Protein ids.

– PRIDE viewer (http://proteo.cnb.csic.es:8080/prideviewer) represents the information from a PRIDE file in a friendly-user manner

WG 3.-Bioinformatics support

– MIAPE-PRIDE API: Automatic generation of MIAPE-MS and MSI reports from PRIDE documents and vice-versa (in development).

– MIAPE to GelML translator: Automatics generation of HUPO-PSI GelML docuemnts from MIAPE-GE reports. Part of GelML specification article (Jones et al. Submitted)
