Extending pathways and processes using molecular interaction networks to analyse cancer genome data

This something really interesting to PPI, Systems biology  and molecular networks people, I just recently came across,
Cellular processes and pathways, whose deregulation may contribute to the development of cancers, are often represented as cascades of proteins transmitting a signal from the cell surface to the nucleus. However, recent functional genomic experiments have identified thousands of interactions for the signalling canonical proteins, challenging the traditional view of pathways as independent functional entities.
Combining information from pathway databases and interaction networks obtained from functional genomic experiments is therefore a promising strategy to obtain more robust pathway and process representations, facilitating the study of cancer-related pathways. 
Results: We present a methodology for extending pre-defined protein sets representing cellular pathways and processes by mapping them onto a protein-protein interaction network, and extending them to include densely interconnected interaction partners. The added proteins display distinctive network topological features and molecular function annotations, and can be proposed as putative new components, and/or as regulators of the communication between the different cellular processes.
Finally, these extended pathways and processes are used to analyse their enrichment in pancreatic mutated genes. Significant associations between mutated genes and certain processes are identified, enabling an analysis of the influence of previously non-annotated cancer mutated genes. 
Conclusions: The proposed method for extending cellular pathways helps to explain the functions of cancer mutated genes by exploiting the synergies of canonical knowledge and large-scale interaction data.

'Omics Projects Snag More than $625M Worth of NIH Stimulus Grants

The National Institutes of Health has awarded 970 stimulus grants worth more than $625 million — around 14 percent of total NIH stimulus grant funding to date — to projects that fall within the broad family of 'omics disciplines, according to a preliminary analysis of the NIH funding database conducted by GenomeWeb Daily News.

As of Sept. 30, the close of the fiscal year, the National Institutes of Health had awarded a total of $5 billion in stimulus funding — nearly half of the $10 billion appropriation that NIH will disburse over two years under the American Recovery and Reinvestment Act of 2009.

The $5 billion figure includes both grants and contracts, however. For grants alone, NIH had awarded approximately $4.4 billion via 12,789 ARRA grants as of Oct. 7, according to the database.

The 970 grants awarded to 'omics projects comprise 7.5 percent of the stimulus grants awarded so far, but the total funding awarded to these projects makes up 14 percent of NIH ARRA grant funding to date.

The largest share of grants — 194 — went to bioinformatics and computational biology projects, for a total of $92.4 million in funding.

Sequencing projects snagged the most amount of total funding, however, with 88 grants worth $129.8 million.

Those disciplines were followed by:

• projects and centers focused on translational research and systems biology, which garnered 148 grants totaling $100 million;
• proteomics projects — including instrumentation grants for mass spectrometers and nuclear magnetic resonance systems — which were awarded 141 grants totaling $57.2 million;
• projects that involved RNAi, microRNAs, and other non-coding RNAs, which snagged 93 awards worth a total of $29 million;
• pharmacogenomics and personalized medicine projects, which were granted 80 awards worth $45.2 million;
• biochips and microarrays — excluding genome-wide association studies — which netted 63 awards worth $33.3 million;
• GWAS studies, which were awarded 28 grants worth $42.8 million;
• epigenomics projects, which received 38 awards totaling $26.1 million;
• metabolomics studies, which garnered 11 grants worth a total of $5.5 million; and
• metagenomics efforts, which received 8 grants worth $6.9 million.

There were 134 grants, worth a total of $113.6 million, awarded to genomics projects that did not fall into any of the above categories (see below for a breakout of the number of grants and the funding amounts awarded to each discipline).

The research institutes that picked up the lion's share of the 970 'omics awards were the University of Washington, with 27 grants worth $24.3 million; Harvard/Harvard Medical School with 26 grants worth $19.8 million; and the University of Michigan at Ann Arbor and Stanford University with 22 grants each worth $18.7 million and $11.8 million, respectively.

The University of Pennsylvania, Johns Hopkins University, and Brigham and Women's hospital were each awarded 19 'omics grants, worth $22.1 million, $10.7 million, and $12.5 million respectively.

The Broad Institute, which was awarded 14 'omics stimulus grants, snagged the most total funding, with $33 million.

The largest single 'omics stimulus award, worth $12.2 million, went to Eric Boerwinkle at the University of Texas Health Sciences Center for a project entitled, "Building on GWAS for NHLBI-Diseases: The CHARGE Consortium."

Other 'omics awards in the double-digit million range went to Wash U, which received $10 million for "Center for Large-Scale Genome Sequencing and Analysis;" the Broad Institute, which received $10.2 million for "Comprehensive Sequencing and Analysis of Variation in NHLBI Cohorts;" and the University of Washington, which received $11 million for "Northwest Genomics Center."

The average amount for 'omics stimulus awards was $644,807, compared to an average of $340,524 for all NIH ARRA awards.

Systems Biology Can Uncover Signatures of Vaccination Immune Response

A team of American and French researchers used systems biology to identify gene signatures predicting human immune responses to the yellow fever vaccine, YF-17D. The work appeared in an advanced online publication in Nature Immunology yesterday.

Using high-throughput gene expression measurements, multiplex analysis of cytokines and chemokines, and multi-parameter flow cytometry, investigators tested samples taken from more than a dozen individuals in the days and weeks following their yellow fever vaccination. Computational modeling allowed them to come up with signatures predicting CD8+ T-cell and neutralizing antibody responses to YF-17D — insights into vaccine immunogenicity that may inform future vaccine research and development.
“The identification of gene signatures that correlate with, and are capable of predicting, the magnitudes of the antigen-specific CD8+ T-cell and neutralizing antibody responses provides the first methodological evidence that vaccine-induced immune responses can indeed be predicted,” senior author Bali Pulendran, an immunologist and virologist at the Emory Vaccine Center in Atlanta, and his colleagues wrote.
The yellow fever vaccine, which was developed in the 1930s, has been administered to more than 600 million people around the world. Because it is among the most effective vaccines to date — protecting 80 to 90 percent of the individuals who receive it — the researchers reasoned that YF-17D could serve as a good model for studying the early immune response to vaccination.

Sequence Analysis is still sexy:Dual Descriptor Method for Biological Sequence Analysis

The emergence of “Systems Biology” in recent years highlights the systematic viewpoint of bio-system modeling. Building on such a background, Dual Descriptor Method, a generic methodology for biological sequence analysis is proposed. From a systematic perspective, Dual Descriptor is defined as a two element set of Composition Weight Map and Position Weight Function which aim at reflecting the composition and permutation information of a sequence. An alternate training algorithm is provided to get an optimum description of the building patterns of the sequences.

In this paper, dual descriptor method has been applied to the analysis of two typical problems of molecular biology: gene identification and the prediction of protein function. Satisfactory and insightful results are achieved. Owing to the generality of this methodology, dual descriptor method has wide application perspective for many problems of pattern recognition, especially those involved in “Systems Biology”.

Enter Little b, a computational language that can penetrate the "mind" of a cell.

DNA is pretty straight forward. With its simple composition and linear structure, it easily lends itself to mathematical models. Not so with proteins. In fact, proteins are an order of magnitude more complex than DNA. It is proteins, not DNA, that carry out the cell's heavy lifting. However, with their intricately folded three-dimensional shapes determining a seemingly endless range of possible functions and their manifold interactions with other proteins and with DNA, the leg-work required to mathematically capture the protein universe seems absurd.

That is why a team of Harvard Medical School researchers have decided to attack this issue from an entirely new angle. Rather than build a mountain range of proteomic data one grain of dirt at a time, they have developed a computer program that can take on the responsibility of assembling such a gargantuan model.

"Through incorporating principles of engineering, we've developed a language that can describe biology in the same way a biologist would," says Jeremy Gunawardena, director of the Virtual Cell Program in Harvard Medical School's department of systems biology. "The potential here is enormous. This opens the door to actually performing discovery science, to look at things like drug interactions, right on the computer."

These findings will be published in the July 23 issue of Journal of the Royal Society Interface.

"Programming with models: modularity and abstraction provide powerful capabilities for systems biology"

Aneil Mallavarapu, Matthew Thomson, Benjamin Ullian, and Jeremy Gunawardena

Department of Systems Biology, Harvard Medical School, Boston MA

Mallavarapu used the programming language LISP, a language widely used in artificial intelligence research. LISP is famous among computer scientists due to its ability to write code that, in turn, can write code, enabling a programmer to derive new mini-languages.

"LISP isn't like typical programs, it's more like a conversation," says Gunawardena. "When we input data into Little b, Little b responds to it and reasons over the data."

For example, Gunawardena's lab works on kinases, a kind of protein that transfers phosphate chemicals to other proteins in order to regulate their activity. While this property is common to all kinases, there is a great deal of variety in how particular kinases carry this out. Little b, however, understands this basic property of kinases, this abstraction.

Here, the researchers demonstrated how they were able to interact with Little b to build complex models of kinase activity, using Little b as a kind of scientific collaborator, and not simply a passive tool.

"This language is stepping into an unknown universe, when your computer starts building things for you," says Gunawardena. "Your whole relationship with the computer becomes a different one. You've ceded some control to the machine. The machine is drawing inferences on your behalf and constructing things for you."

"The next step is to create an interface that's easy to use," says Gunarwardena. "Think of web page development. Lots of people are creating web pages with little or no knowledge of HTML. They use simple interfaces like Dreamweaver. Once we've developed the equivalent, scientists will be able to use our system without having to learn Little b."

VisANT: an integrative framework for networks in systems biology

Integrative Visual Analysis Tool for Biological Networks and Pathways

Already blogging on the topic Structured Digital Abstracts - Easier Literature Searching dicussing the inportance of networks in the form of interactions, and further in several others about visualization tools, here is one more.

The essence of a living cell is adaptation to a changing environment, and a central goal of modern cell biology is to understand adaptive change under normal and pathological conditions. Because the number of components is large, and processes and conditions are many, visual tools are useful in providing an overview of relations that would otherwise be far more difficult to assimilate. Historically, representations were static pictures, with genes and proteins represented as nodes, and known or inferred correlations between them (links) represented by various kinds of lines. The modern challenge is to capture functional hierarchies and adaptation to environmental change, and to discover pathways and processes embedded in known data, but not currently recognizable. Among the tools being developed to meet this challenge is VisANT (freely available at http://visant.bu.edu) which integrates, mines and displays hierarchical information. Challenges to integrating modeling (discrete or continuous) and simulation capabilities into such visual mining software are briefly discussed.
