Microbial cellular and community networks; influence of environmental change on the evolution of molecular processes; systems biology; bioinformatics We use systems-level approaches to understand bacterial stress response networks related to host-pathogen interactions and the influence of global climate change on populations of marine cyanobacteria and communities of bacteria. Our research program is characterized by a synergistic integration of computation, experiment and theory and we welcome new people from different academic disciplines. There are three fundamental aspects of our research; (1) Effectively utilize genomic data from different sources to discover functions for genes and proteins. (2) Uncover rules governing and constraining biological systems. (3) Enable predictive models of biological systems that incorporate biochemical and genetic data. Here are some of our project areas for systems research.
The effects of global climate change on populations of marine cyanobacteria
Global climate change is an international problem that already is impacting the evolutionary trajectory of our planet's biota. In spite of the widely appreciated magnitude of this problem, we still have a limited ability to estimate current and long-term biological effects. As the most numerically dominant species in the ocean, Prochlorococcus has become a central object of study for understanding carbon fixation by photosynthetic organisms. Prochlorococcus is very unusual for a free living organism in that it show signs of reductive genome evolution that are typically found in organelles, endosymbionts and pathogens (see Blanchard et al. 2000) and now has a minimal transcriptional regulator network for sensing environmental change. The long-term goal of our research is to integrate large-scale “genomic” data sets into probabilistic models that allow inferences and decisions regarding the trajectory of photosynthetic organisms in a changing global climate. Towards this goal we are working on;
• Integrating genome sequence and expression microarray data into models that allow us to identify process and subnetworks subject to different selective pressures related to changes in ocean chemistry. • Developing and applying statistical methods to identify regulatory motifs and their relative binding strength in sequence data using a combination of microarray and sequence data (In collaboration with Erin Conlon).
Stress response networks in enteric bacteria (In collaboration with Pablo Pomposiello)
Signals initiated by diverse factors involved in host pathogen interactions, including antibiotics and nitric oxide, are funneled by three dissimilar sensor transcriptional regulators (SoxR, MarR and RamR) to three homologous transcriptional activators (SoxS, MarA and RamA) to regulate a similar but not completely overlapping set of genes coding for key metabolic control points and defense mechanisms. This unusual regulatory circuit design was assembled fairly recently in the ancestor of Escherichia, Salmonella and Klebsiella and soxS, marA and ramA are derived from duplications events that occurred around this time. Because, these transcriptional activators historically bound the same set of genes we are using comparative experimental and computational approaches for determining the regulatory network structure and creating models that describe the response of the bacteria to host and other environmental factors.
Microbial environmental and community genomics
Most microbes are currently impossible to grow in the laboratory. New approaches are being developed to sequence genomes of microbes straight from environmental samples obviating the need to first culture microbes. One spectacular application of this evolving technology was to a microbial community in the Sargasso Sea (Venter et al. 2004). The published data set included at least 1800 bacterial species many which have not been previously described. Fortunately for us there is also a lot of sequence data on marine cyanobacteria, particularly Prochlorococcus marinus. We have developed a new method for separating genomes from cocultures of bacteria (in collaboration with Derek Lovely) and are applying the methods to the Sargasso Sea and other environmental sequencing data sets. We are also interested in developing methods that utilize variation in DNA sequences to understand microbial population dynamics and methods for building a conceptual model of the interactions among various members of these communities.

NCGR :: About NCGR
"We are what we repeatedly do. Excellence, then, is not an act, but a habit. " -- Aristotle
STRATEGIC INTENT
NCGR is a nonprofit life sciences research institute.
Our mission is to translate research at intersections between bioscience, computing and mathematics into improvements in infectious disease, global health, and nutrition.
Our objectives are improved diagnosis, control and cure of infectious disease, and better nutrition and food safety.
Our approach is the development of innovative computational solutions using: Integrated informatics, Inferential statistics, and Complex Networks Analysis.
RESEARCH TOPICS
Through our research programs, NCGR develops technologies that help scientists comprehend biological data. People around the world can benefit from our research programs through improved food crops, a cleaner environment, and better medical treatments.
Scientists who use our programs or collaborate with us choose NCGR because we provide unique opportunities for understanding data.
GENETIC VARIABILITY
The Center's research programs focus on understanding the dynamics of infectious diseases and genetic variability on human health by using our expertise in biological research and information technologies. NCGR's core interests include expertise in simulation modeling, population genetics, quantitative genetics, biological networks, and information systems integration.
BIOINFORMATICS
The Bioinformatics Program at NCGR is devoted to the development of computer software products that provide scientists with resources for addressing issues of biological importance. Some of the projects currently under development within the Bioinformatics Program include The Arabidopsis Information Resource (TAIR) and the Model Plants Initiative (MPI).
COMPUTATIONAL SYSTEMS BIOLOGY
Computational Systems Biology focuses on the bioinformatic application and development of computational techniques from a systems biology perspective. This paradigm involves the use of computers and associated databases and algorithms to build explanatory and predictive models for biological systems from the molecular to the ecosystem level.
BIOLOGICAL PATHWAY RECONSTRUCTION
In living cells, biological pathways are integrated to form intricate regulatory networks that respond and adapt to changing environments. We have learned basic statistical properties that explain the robustness and resistance to random perturbation of individual components of networks, but the underlying principles of network evolution and extensibility have not been revealed.
With the accelerated accumulation of various molecular data, we can start to address these questions. One particular example of a regulatory network is the apoptotic machinery that is fundamental to the development, maintenance, and survival of multi-cellular organisms. We are dissecting the building blocks of this regulatory network from genomics to proteomics to further understand its cellular regulation.
GENE EXPRESSION INTERPRETATION
A cell has thousands of genes. At any instance, some of these genes are used to produce proteins while others lie quiescent. As a cell grows, metabolizes, or responds to stimuli, different genes are used to make proteins in different proportions. By studying the process of cell growth scientists observe the conditions that foster the selection of genes.
Data generated from gene expression arrays allow scientists to measure gene regulation. Research at NCGR on gene expression focuses on many areas: developing a gene expression data management system with the incorporation, compatibility, exchangeability, and comparability of expression data from many different technologies into an integrated database; understanding the functions of hypothetical proteins; analyzing gene expression data using heterogeneous, synthesized, and distributed biological databases and resources; finding gene regulatory networks based on knowledge discovery and multistage optimization; and using molecular expression to diagnose diseases.
FROM GENOTYPE TO PHENOTYPE
To enable predictive system level models we need to better understand phenomenon related to cellular interactions including robustness, buffering, canalization and epistasis. The focus of NCGR's research is the "middle layer" of cellular networks that influences the translation of genotypes with relevant environmental parameters into phenotypes. Our goal is to encapsulate data related to the fundamental cellular building blocks of genes, proteins and metabolites into models that predict change in phenotypic tratis in response to environmental and genetic changes.
EVOLUTION OF RECOMBINATION
Virtually all organisms exchange their DNA with other organisms. This process, broadly known as recombination, occurs during the production of gametes, in a process known as meiosis, in plants and animals. This is of particular interest to scientists since uncontrolled cellular replication is the hallmark of cancer. NCGR research focuses on a bioinformatic reconstruction of the biochemical pathways involved in yeast DNA repair, meiosis, and replication, and links them to a theoretical population genetic understanding of the evolution of recombination and meiosis. By understanding how these pathways evolved and how they function, we are better able to understand the genes that are responsible for the body's response to DNA damage and its natural suppression of cancer. Conversely, the elucidation of these pathways yields answers on the evolution of the process of meiosis itself.
DATA INTEGRATION
NCGR'S Integrated System, ISYS™, is the result of our research into data and system integration. It is a software platform allowing integration of many tools that manage and analyze biological data. It provides an intuitive environment for investigators to explore data and detect relationships that they might not otherwise see. ISYS's strength is that it provides a way for tools that may have been developed completely separately from each other or ISYS to share data and operate interactively.
