HUPO World Congress Publication Committee Meeting August 2008, Amsterdam,The Netherlands

The plenary session of the Publications Committee of the Human Proteome Organisation at the 7^th annual HUPO world congress examined the relationship between journals, proteomics standardization initiatives, such as the work of the HUPO‐PSI, and the public domain data repositories. Delegates from industry, academia and the publishing houses discussed how best to bring these bodies closer to together and facilitate the publication process for the bench scientist.     

Proteomics for everyday use: activities of the HUPO Brain Proteome Project during the 5th HUPO World Congress

Long Beach hosted this year's annual congress of the Human Proteome Organisation (HUPO). In addition to the numerous sessions, talks and poster presentations organized by HUPO itself, several events were arranged by the HUPO initiatives. The Brain Proteome Project (HUPO BPP) was very active, initiating three pre-congress workshops: (i) the kick-off meeting of the EU-funded ProDaC consortium (Proteomics Data Collection) that is aiming at the bioinformatics Standardization in the proteomics field; (ii) the workshop "Standardization Issues in Proteomics: Perspectives from Vendors" giving an overview about the lessons learned by proteomics industrial partners; (iii) the 6th HUPO BPP Workshop "New Proteomics Approaches for further HUPO BPP Studies" offering new concepts for brain-related proteomics studies.     

A comparison of the HUPO Brain Proteome Project pilot with other proteomics studies

The pilot phase of the Brain Proteome Project (BPP), the Human Proteome Organization (HUPO) initiative that focuses on studies of the brain of both humans and mice, has now been completed. Participating laboratories studied the proteomes of two human samples derived from biopsy and autopsy as well as three mouse samples from various developmental stages. With the combined and centrally reprocessed data now available, a comparison in terms of protein identifications and project organization is made between the HUPO BPP pilot and three other proteomics studies: the HUPO Plasma Proteome Project (PPP) pilot, a proteome of human blood platelets and a recently published comprehensive mouse proteome. Finally, as any comparison between large-scale proteomics datasets is decidedly non-trivial, we also evaluate and discuss several ways to go about comparing such different result sets.     

The HUPO Plasma Proteome Project: a report from the Munich congress

The Human Proteome Organization has several major collaborative research initiatives, including the Plasma Proteome Project. A major feature of the HUPO World Congress in Munich in August 2005 was the release of the special issue of PROTEOMICS with 28 articles from the pilot phase of the Plasma Proteome Project. An open Workshop and a presentation in the closing plenary session of the congress focused on next phases for the Plasma Proteome Project.     

The HUPO Brain Proteome project wish list--summary of the 9(th) HUPO BPP Workshop 9-10 January 2008, Barbados

The Human Brain Proteome Project (HUPO BPP) aims at advancing knowledge and the understanding of neurodiseases and aging with the purpose of identifying prognostic and diagnostic biomarkers, as well as to push new diagnostic approaches and medications. The participating groups meet in semi-annual workshops to discuss the progress, as well as the needs, within the field of proteomics. The 9(th) HUPO BPP workshop took place in Barbados from 9-10 January, 2008. Discussing the future HUPO BPP Roadmap, the attendees drafted the so called HUPO BPP wish list containing timelines, suggestions and missions. This wish list will be updated regularly and will serve as a guideline for the next phase.     

The HUPO initiative on Model Organism Proteomes, iMOP

The community working on model organisms is growing steadily and the number of model organisms for which proteome data are being generated is continuously increasing. To standardize efforts and to make optimal use of proteomics data acquired from model organisms, a new Human Proteome Organisation (HUPO) initiative on model organism proteomes (iMOP) was approved at the HUPO Ninth Annual World Congress in Sydney, 2010. iMOP will seek to stimulate scientific exchange and disseminate HUPO best practices. The needs of model organism researchers for central databases will be better represented, catalyzing the integration of proteomics and organism-specific databases. Full details of iMOP activities, members, tools and resources can be found at our website http://www.imop.uzh.ch/ and new members are invited to join us.

A proteomic study of the HUPO Plasma Proteome Project's pilot samples using an accurate mass and time tag strategy

Characterization of the human blood plasma proteome is critical to the discovery of routinely useful clinical biomarkers. We used an accurate mass and time (AMT) tag strategy with high-resolution mass accuracy cLC-FT-ICR MS to perform a global proteomic analysis of pilot study samples as part of the HUPO Plasma Proteome Project. HUPO reference serum and citrated plasma samples from African Americans, Asian Americans, and Caucasian Americans were analyzed, in addition to a Pacific Northwest National Laboratory reference serum and plasma. The AMT tag strategy allowed us to leverage two previously published "shotgun" proteomics experiments to perform global analyses on these samples in triplicate in less than 4 days total analysis time. A total of 722 (22% with multiple peptide identifications) International Protein Index redundant proteins, or 377 protein families by ProteinProphet, were identified over the six individual HUPO serum and plasma samples. The samples yielded a similar number of identified redundant proteins in the plasma samples (average 446 +/- 23) as found in the serum samples (average 440 +/- 20). These proteins were identified by an average of 956 +/- 35 unique peptides in plasma and 930 +/- 11 unique peptides in serum. In addition to this high-throughput analysis, the AMT tag approach was used with a Z-score normalization to compare relative protein abundances. This analysis highlighted both known differences in serum and citrated plasma such as fibrinogens, and reproducible differences in peptide abundances from proteins such as soluble activin receptor-like kinase 7b and glycoprotein m6b. The AMT tag strategy not only improved our sample throughput but also provided a basis for estimated quantitation.     

HUPO Brain Proteome Project Pilot Studies: bioinformatics at work

The data acquisition phase of initial pilot studies (human and mouse brain samples) of the Human Proteome Organisation (HUPO) Brain Proteome Project (BPP) is now complete and the data generated by the participating laboratories has been submitted to the central Data Collection Center. The BPP Bioinformatics Group met on 8th April 2005 at the European Bioinformatics Institute (Hinxton, UK) to discuss strategies for the reanalysis of the pooled data from all the participating laboratories. A summary of the results of the data reprocessing will be presented at the 4th HUPO World Congress that will be held in August/September 2005.
