Computational Proteomics: Management and Analysis of Proteomics Data

CALL FOR PAPERS
Proteomics is a fastly developing area of biochemical investigation. The basic
aim of proteomic analysis is the identification of specific protein patterns
from cells, tissues and biological fluids related to physiological or
pathological conditions. It provides a different view as compared to gene
expression profiling, which does not evaluate post-transcriptional,
post-translational modifications as well as protein compartimentalization and
half-life changes (for instance ubiquitination and proteasome-driven
degradation). All these characteristics make the protein profile much more
complex but more informative compared to gene expression profiling.
Several approaches have been used to perform proteomic analysis; among them,
technologies based on Mass Spectrometry (MS) have revolutionized proteomics
and are heavily used to make high-throughput measurements for identifying
macromolecules in a specific compound. Recently, Liottas group at the
National Institutes of Health, USA, using SELDI-TOF mass spectrometry, has
identified in the serum of patients with ovarian cancer a cluster pattern
that completely segregated cancer from non-cancer. These results,
characterized by a high degree of sensitivity and specificity, represent an
extraordinary step forward in the early detection and diagnosis of ovarian
cancer and justify a prospective population-based assessment of proteomic
pattern technology as a screening tool for all stages of ovarian cancer in
high-risk and general populations. Similar studies performed on different
types of neoplastic diseases have confirmed the importance of identification
of molecular profiles or signatures (either at RNA or protein level) as a
powerful tool for innovative diagnostic and therapeutic approaches.
This Special Track is designed to bring together computer scientists,
biologists and clinicians for exploring the current state-of-the-art research
taking place in all aspects of computational proteomics, from basic science
to clinical practice. The track intends to provide a forum for the
presentation of original research, valuable software tools (basic algorithms,
modelling, analysis, and visualization tools, databases), and clinical
fallouts, on topics of importance to computational proteomics, with special
emphasis on MS-based approaches.
Matrix-Assisted Laser Desorption/Ionisation Time Of Flight (MALDI-TOF),
Surface-Enhanced Laser Desorption/Ionization Time Of Flight (SELDI-TOF), and
Liquid Chromatography (LC-MS/MS) are the main techniques. They separate gas
phase ions according to their m/Z (mass to charge ratio) values producing
huge volumes of data. MS output is represented, as a (large) sequence of
value pairs, containing a measured intensity, which depends on the quantity
of the detected biomolecules and a mass to charge ratio m/Z, which depends on
the molecular mass of detected biomolecules. A MS experiment usually
generates one or more datasets, said spectra, that contains a huge quantity
of measurements (m/Z, intensity) said peaks.
MS-based proteomics requires bioinformatics methods that can make biological
inferences from both the raw experimental data sources (e.g., peptide
identifications and mass measurements) and the resulting identifications.
Prior to be analysed, spectra need to be cleaned, pre-processed, organized,
and stored in an efficient way. Moreover, standard formats enabling
laboratory interoperation and experiment replication are needed. The Human
Proteome Organization-Proteomic Standard Initiative (HUPO-PSI) is defining
novel standards for proteomics data and experiments such as mzData to store
spectra data as well as metadata information about proteomics experiments,
and mzIdent capturing parameters and results of search engines such as Mascot
and Sequest.
On the other hand, alone or in combination with MS, fluorescence-based
techniques are also used for proteomics analysis. Differential display
proteomics increases the information content and throughput of proteomics
studies through multiplexed analysis. Main approaches to differential display
proteomics such as Difference Gel Electrophoresis (DIGE), Multiplexed
Proteomics (MP), and Isotope-Coded Affinity Tagging (ICAT), greatly enhance
the applicability of the Two-Dimensional Gel Electrophoresis technique
(2D-Gel).
Representation, organization and analysis of fluorescence-based proteomics
data, such as 2D-Gel data, are also important topics.
Genomic and Proteomic data need to be analyzed in combination. The full
realization of the concept of genomic medicine, where genomics and proteomics
are used to improve healthcare, requires the integration of knowledge from
biology and medicine. To exploit the data available in research centres and
care facilities new frameworks integrating data, computational methods and
tools have to be provided, that bridge bioinformatics, biology and medicine.
The semantic integration and further analysis of genomic, proteomics and
clinical data is a first step toward the deployment of novel biomedical
applications involving research-oriented competence centres, specialized
proteomics facilities, and
health centres where clinical guidelines are applied.
Key issues to be faced when considering integrated management and analysis of
MS proteomics data are:
* spectra data models and databases;
* spectra pre-processing;
* spectra analysis (e.g. peptide identification, protein identification,
etc.);
* spectra visualization;
* integration and interaction with biological data banks (e.g. sequence,
structure, and peptide data banks);
* data models and databases for integrated genomics and proteomics data;
* integrated analysis of genomic and proteomic data with clinical/instrumental
findings;
* identification of new biomarkers for early diagnosis and tailored
therapeutics;
TOPICS OF INTEREST
Methods, algorithms and techniques for proteomics data organization, storage
and analysis, as well as the use of proteomics methods and techniques in
clinical practice are the key topics of this Special Track. Whatever
technique being used, proteomics data are huge, involve heterogeneous
platforms and require high performance computing, so presentation of high
performance and Grid-based computational methods, as well as semantic-rich
methods for in silico workflow composition are welcomed. Examples of areas of
interest include, but are not restricted to:
* Spectra data models and databases
* Spectra-related data banks (e.g. Mascot, Sequest)
* Spectra pre-processing algorithms
* Peptide/protein identification
* Protein-protein interactions
* Data Mining techniques for proteomics data
* Statistical analysis of proteomics data
* Image analysis and visualization of proteomics data
* 2-D Gel proteomics data and analysis
* Virtual Proteomics Laboratory
* Data integration and proteomics
* Technologies and models to store phenotype, genotype and proteotype data;
* Integration of proteomics and clinical data for diagnosis and treatment
* Application of proteomics methods in clinical practice
* Workflow of proteomics experiments
* Knowledge Management and ontologies in proteomics
* Parallel and Grid-based computational proteomics
* Standards in proteomics

PAPER SUBMISSION
Unlike workshops, where position papers and reports on initial and intended
work are appropriate, papers selected for a special track should report on
significant unpublished work suitable for publication as a conference paper.
Interested authors should submit a 3-6 pages manuscript (or approximately
1500-3000 words) clearly describing background, goals, methods, results and a
listing of primary references. Presented material should include sufficient
detail to enable the program committee in reviewing the article.
The article should be composed on US Letter page format and submitted as a PDF
or Microsoft Word document. The article review is double blind and as such
personally identifying information is discouraged. Author name and address
should be withheld from the article text for review purposes. Article text
should be in font size of at least 10 point. Authors should indicate the
Special Track title in their submissions. All submissions including special
track papers will be done electronically via the CBMS web submission system,
which will be open approximately one month before the deadline.
Please note that the format of IEEE CBMS 2006 proceedings will be the IEEE
