About the Lab

Tay Lab for Bioengineering and Systems Biology

We want to understand how cells process information, especially in the context of the immune response. NF-kappaB is a central innate immune pathway that responds to hundreds of signals including cytokines and pathogens, and controls the expression of thousands of genes. We previously investigated NF-kappaB dynamics at the single-cell level using high-throughput microfluidic microscopy and quantitative gene expression (Tay et al. Nature 466, 267). Contrary to what bulk assays show, we discovered that single-cell responses are highly heterogeneous, both in cell activation probability and dynamics of the NF-kappaB transcription factor, as well as downstream gene expression dynamics. The input signal intensity (i.e. cytokine concentration) determines the probability of activation, response time and the duration of NF-kappaB oscillations, but not the intensity of the response (i.e. nuclear translocation amplitude), therefore termed digital activation. We also showed that digital signaling propagates to downstream target genes, with early genes activating digitally and late genes activating in analog, concentration dependent fashion.

To understand the underlying mechanisms and to predict complex signaling scenarios, we developed a stochastic computer model of the NF-kappaB pathway based on our comprehensive single-cell data. This is the most broadly applicable and accurate model of the NF-kappaB pathway to date, reproducing great majority of the observed characteristics under all input signal levels. We are using this model as a test-bed for future experiments and discoveries.

Future directions in our lab include the investigation of the mechanisms behind stochastic and digital activation, and the emergent properties of this complex signaling scheme in pathogen-host interactions and tissue inflammation. For this effort, we combined probably the most powerful arsenal of single-cell analytical tools in the world, namely high-throughput automated microfluidic cell culture, automated live cell imaging and tracking, high-throughput single-cell gene expression (qPCR) and digital-PCR, and single-cell digital protein counting. This pipeline, applied to cells expressing fluorescent fusion proteins and reporters, can generate terabytes of dynamic single-cell data every week, with unprecedented degree of control, accuracy and reproducibility. Using these awesome tools, we are investigating the spatio-temporal emergent properties of digital cell activation. New technologies based on microfluidics and optogenetics will also be developed to simulate these scenarios. Our previous single-cell model will be expanded and used to guide further experimental studies.

About the Lab

My laboratory focuses on numerous key aspects of how bacteria assemble into distinct communities, the metabolic mechanisms that structure these assemblages, and whether these systems can be predictively modeled over time and space. We use next generation sequencing approaches to access phylogenetic and functional information embedded within the genes of bacteria that populate these communities.  Our goal is to use this information to reconstruct community interactions, and ultimately to build statistical models of the microbial ecosystem.  These models will help us visualize large-scale patterns, generate predictions of responses to changes in an environment, and to identify gaps in our sampling campaigns.

We are a very collaborative group. Currently, we are involved in the (1) Earth Microbiome Project, which is a systematic characterization of microbial life across the biomes of planet earth; (2) Home Microbiome Project, an ongoing study to determine the rate and direction of microbial interaction between people, their pets and their homes; (3) Chicago Waterways Metagenomic Initiative, which aims to map and model the dynamics of microbial metabolism in the Chicago River and surrounding canals; (4) The Gulf of Mexico Microbial Metabolic Modeling Initiative that will map and model the microbial dynamics of the Gulf of Mexico; (5) American Gut, which aims to characterize the microbial diversity of 20,000 humans over the next 2 years; (6) The Autism Microbiome Consortium, which is providing a nexus for research into the influence of microbial metabolism on the symptoms of Autism; (7) Microbial Assemblage Prediction, which involves developing microbial modeling tools capable of allowing global forecasting of microbial community structure and metabolic potential across planet earth.

Our group also leadS the Hospital Microbiome Project, which is characterizing the taxonomic composition of surface-, air-, water- and human associated microbial communities in the new Center for Care and Discovery hospital.  The aim is to determine the influence of human population demographics on the directionality in which the microbial communities evolve and the rate of colonization by potential pathogens.

In addition to these core projects, we also have over 35 ongoing collaborations with researchers from around the world and right here in Chicago.

Jack Gilbert weighs in on whether probiotics are truly good for you

Watch UChicago’s Jack Gilbert and Julie Bubeck Wardenburg weigh in on whether probiotics are truly good for you in the latest video from Argonne’s Microbiome Project series here.

Jack Gilbert named in Science Brilliant 10.

Every year, Popular Science honors the 10 brightest young minds that are reshaping science and the world.
IGSB’s Jack Gilbert was named in the top 10, highlighting his work profiling microbiomes, for his energy and enthusiasm as well as his love for Ice Cream. 

Jack Gilbert is the Field Museum’s newest Research Associate

IGSB’s Jack Gilbert is the Field Museum’s newest Research Associate. This appointment is the latest collaboration between the Field museum and IGSB. Over the past 4 years Jack has been developing research collaborations with scientists at the Field museum to study the microbiome of Ants and Birds.

Looking Closer at the Role of Microbiome

"...In fact, it’s beneficial. It helps train your immune system.” Your body wants it there, needs it there, has evolved to live with it. “It’s a natural part of your gut’s flora, your ecosystem.”

How Germs Might Shape the Future of Architecture

Do building materials affect how bacteria behave? That’s what Jack Gilbert, an environmental microbiologist at the University of Chicago, is investigating. He examines the metabolism of specific microbes under different indoor conditions. He’ll spray bacteria onto a variety of materials, such as steel, wood, and copper, looking for changes in their growth and proliferation, and he’ll adjust certain environmental variables, such as temperature and humidity—things humans like to control.

IGSB Core Member Recognized by Crain’s “40 Under 40”

IGSB Core Member Jack Gilbert was honored by Crain’s Chicago Business as a proven leader in his field. Previous winners before their 40th birthday include Barack Obama, Nate Silver, and Kevin White.

About the Lab

The overriding research interest of the lab is trying to disentangle the relationship between genotype and phenotype, and to understand the forces shaping functional genetic variation in humans. We use a combination of experimental and computational approaches: We employ high-throughput functional genomics and genome-wide association analysis (GWAS) to identify variable regions of the genome with functional effects on the transcriptome and proteome, and to investigate the context-specificity of these patterns. At the same time, we examine the levels and patterns of genetic variation within and between human populations, and between human and other species to identify regions of the genome with patterns of variation suggestive of natural selection.

Current projects in the lab investigate genetic effects on transcriptome regulation in disease contexts that include cancer, immune-mediated diseases, neuropsychiatric diseases, and pre-eclampsia. We also have a project examining the role of genetic regulation of the transcriptome in pharmacogenomics phenotypes. In parallel, as part of the ImmVar Consortium, we are studying immune cells of healthy cohorts to obtain a baseline against which to compare disease regulatory networks in immune-mediated diseases. We are active members of the Analysis Working Group of the Genotype-Tissue Expression (GTEx) Consortium, and have received funding to generate proteomic data and to perform analyses associating genetic variation data with proteomic expression data within and between tissues of the GTEx cohort. These approaches complement disease-mapping studies and provide hypotheses for the mechanism of action of specific variants in creating disease phenotypes.

We recently integrated GWAS results with protein-protein interaction networks and transcriptome data to examine the relationship between genome evolution and inflammatory disease (Raj et al, 2013).  We identified 21 genome regions with a ‘signature’ for both inflammatory disease susceptibility and natural selection. Our study suggests that genetic variants selected through human evolution based on their ability to function in pathogen-protection mechanisms can - in our modern, more pathogen-free, environment – predispose to autoimmune disease.

In Li et al (2014), we combined GWASs and data from The Cancer Genome Atlas (TCGA) to gain insight into the mechanisms by which cancer risk alleles predispose to disease.  We performed expression quantitative trait locus (eQTL) analyses for mRNA and miRNA expression levels in five tumor types (breast, colon, kidney, lung and prostate), thus identifying the germline genetic determinants of tumor gene expression and microRNA expression. We next tested 149 known cancer risk loci for eQTL effects, observing that nearly 30% were significantly associated with at least one transcript. For each of the risk loci, our study suggested 1 to 81 candidate causal variants that may be prioritized for downstream functional analysis. In summary, our study provided a comprehensive landscape of the genetic determinants of gene expression in different tumor types and ranked the genes and loci for further functional assessment of known cancer risk loci.

The lab is also interested in projects that are less disease centric and would be categorized as basic genome science.  We are interested in investigating:  1) the evolution of paralogs in the human genome; 2) the influence of genetic variation, ancestry, age, sex, cell-type, epigenome, and tissue-type on transcriptional networks; 3) genetic and epigenetic roles in gene splicing and 4) population genomics of regulatory regions and variants. We are constantly re-tooling and developing new analytic methods and tools to most effectively and efficiently make use of large-scale genomics data.

NIH Funding to Study the Effects of Gender on Complex Human Traits

IGSB core investigator <a href="/people/barbara-stranger">Barbara Stranger</a> received supplemental funding from NIH to explore the effects of gender on human traits. 

IGSB Core Member Co-Authors Paper

Barbara Stranger and her lab led analyses of data published in the journal, Science. The report, “Polarization of the Effects of Autoimmune and Neurodegenerative Risk Alleles in Leukocytes,” demonstrates how genetic variations among healthy, young individuals can influence immune cell function. Many of those variants are also genetic risk factors for Alzheimer’s disease, diabetes, and multiple sclerosis later in life, offering new insight into disease pathology.

Immunity, inflammation and natural selection

Barbara Stranger and colleagues take a systems approach, integrating GWAS, eQTL and protein interaction data, to demonstrate that loci associated with inflammatory disease susceptibility are enriched for genomic signatures of recent evolutionary selection.  Their analyses suggest that natural selection for pathogen-defense mechanisms through human evolution may underlie modern susceptibility to inflammatory diseases.

About the Lab

My lab is interested in understanding how the properties of living cells emerge from the stochastic reactions of molecular components. We use a mixture of biophysical, biochemical, genomic, mathematical modeling, and single-cell microscopy approaches to link the properties of molecules to the systems-level behavior of cells. Most of our attention is currently focused on an oscillatory protein network found in the cyanobacterium Synechococcus elongates that the organism uses to predict the time of day. Remarkably, the biological rhythms generated by this circadian clock can be reconstituted in a test tube using three purified protein components - KaiA, KaiB, KaiC - making this the best-defined biological oscillator currently known. It is possible to reconstitute metabolic input signaling to this minimal clock by varying ATP and ADP concentrations (Rust et al, 2011).  We are actively pursuing a quantitative understanding of the reactions that generate oscillations and the robustness properties of this minimal circadian clock. We are also working outward to expand the functions that can be studied in a purified context and include additional components from the in vivo clock system. We seek to tie the biochemical and biophysical properties of these components back to physiologically relevant conclusions for the organism by making quantitative measurements of growth rate and single-cell behavior, including experiments that are uniquely possible in microbial model systems.


We have recently shown that both robustness and adaptability of the clock are determined by the two enzymatic domains of KaiC (Phong et al, 2013).  One of the domains, CII, phosphorylates itself in response to input signals.  CI, a domain of previously unknown function, is insulated from input signals and sets a slow, constant timescale for the interaction between KaiC and the negative regulator KaiB. By building mathematical models of this system, we showed that this two-domain architecture is needed to get the combination of robust period and tunable phase in the circadian clock.  These models will help to illuminate the structures of the clock networks in humans and other organisms where input-sensitive and input-insensitive feedback loops may also be required for proper function.

Researchers Reset Bacteria’s Internal Clock by Rewiring Metabolism

The Rust Lab separated metabolism from light exposure by using a synthetic biology approach to make photosynthetic bacteria capable of living on sugar, rather than sunlight. “I was surprised that this actually worked—by genetically engineering just one sugar transporter, it was possible to give these bacteria a completely different lifestyle than the one they have had for hundreds of millions of years,” says Dr. Rust.

Protein Drives Timekeeping System

In a study soon to appear in print in the journal Science, IGSB faculty Mike Rust and his team show how the highly unusual movements of a single protein drives the shift from nighttime to daytime biological functions in cyanobacteria.
The circadian clock drives powerful rhythms of rest and activity with your internal clock synchronized with local time. At night, you feel tired and in the morning, you feel ready to take on the world. You get jet lag when your clock — and therefore physiology and metabolism — are out of sync with your environment.

IGSB Students Participate in iGEM Competition

IGSB students in Mike Rust's lab are collaborating on an International Genetically Engineered Machines (iGEM) project about synthetic biology. IGSB team members are using standardized biological parts provided by iGEM and molecular components they have devised to engineer E.coli mutator strains that can optimize the production of a desired metabolite using a novel technique in directed evolution. The team will go to the 2014 iGEM jamboree at MIT to present their research. Participating iGEM teams from around the world will also attend and demonstrate synthetic living systems with innovative functions and capabilities.

About the Lab

My laboratory specializes in microbial ecology and using metagenomic-enabled approaches to study communities of microorganisms in a variety of environments. We apply next-generation DNA sequencing technologies towards describing both the structure and function of microbial communities in these systems, taking advantage of the computational resources available at Argonne for handling the scale of data afforded by these technologies. I started my career as a microbiologist studying the cellulose-degrading capabilities of bacteria from production livestock, making extensive use of anaerobic cultivation buoyed by the then emerging area of comparative microbial genomics.  My interest in understanding mammalian gastrointestinal function has expanded to research in environmental systems (subsurface and topsoil systems) using metagenomics. Although the scales are vastly different between the two, similar approaches based in classical ecological theory can be used for both gastrointestinal and field research to circumnavigate the complex microbial communities underlying system function.

In collaboration with colleagues at the University of Chicago these approaches were used to understand the role that diet plays in promoting complex immune disorders such as inflammatory bowel diseases (IBD). This study, which appeared in the journal Nature, provides new insights into why some people are more likely than others to develop IBD (Devkota et al, 2012). Working with a mouse model, we traced both the shift in the microbial community structure and the corresponding host immune response to a diet high in saturated (milk-derived) fats. To dissolve such fats, the liver produces a form of bile rich in sulfur. When the bile reaches the intestines, a microbe called Bilophila wadsworthia – the name means “bile loving” – blooms. Such blooms can trigger the immune system in people with a genetic predisposition. Moreover, the byproducts of this microbe’s interaction with bile can amplify the effect, making the bowel more permeable and unleashing an unregulated immune response in individuals at high risk for diseases such as IBD.

About the Lab

Our group is engaged in a series of computational projects that involve mathematical modeling and analysis of disparate data sets, such as electronic medical records, scientific texts, and high-throughput experimental data.  The overarching goal of such analyses is formulating and testing hypotheses regarding interplay of genetic and environmental mechanisms of human disease.  Formulation and testing of models requires dynamic collaboration with a range of experts in disease phenotype, genetics, statistical modeling, epidemiology, and sociology of science.  We also closely collaborate with groups producing high-throughput data on data interrogation and experimental validation of computational predictions.

We are currently developing approaches for large-scale modeling and analyses of a time-series of phenotypic and environmental records, as represented in patient record databases.  In parallel, we are developing models to analyze gene association and genetic linkage data in a molecular network context, explicitly allowing for multigenic models.  We will implement joint probabilistic models of groups of disease phenotypes, accounting for their dependence on genetic variation, the proximity of genes in molecular networks, and environmental events.  Our aim is to integrate these multi-level models to jointly analyze genomic, clinical and textual data, so as to obtain insights into genetic and environmental factors that, in combination, determine disease phenotypes.

A big data look at improving scientific research: A Q&A with Andrey Rzhetsky

Of all the possible experiments available in biomedical research, only a small subset are ever tackled by scientists. This is in part due to institutional and cultural pressures that lead researchers to avoid risk-taking and choose inefficient research strategies, according to a new study based on a computational analysis of millions of patents and research articles. Despite increased opportunities for groundbreaking experiments, most scientists choose conservative research strategies to reduce personal risk, which makes collective discovery slower and more expensive, conclude Andrey Rzhetsky, PhD, professor of medicine and human genetics and director of the Conte Center for Computational Neuropsychiatric Genomics, and his colleagues.

Health ROI as a measure of misalignment of biomedical needs and resources

In a recently published letter to Nature Biotechnology, Lixia Yao, IGSB core faculty Andrey Rzhetsky and colleagues dissect the decisions made in funding choices. His team compares these choices by funding agencies to trades in a financial market. In this communication, they expand on the idea that there exists an imbalance between health needs and biomedical research investment.

New data-mining effort launched to study mental disorders

About the Lab

The White lab studies the coordinated action of networks of genes that control developmental, disease and evolutionary processes. We have particular focus on discovery of genetic factors that contribute to cancer development and progression, and on building genome-wide models of transcriptional networks. We use an integrated approach that makes use of genome and transcriptome sequencing, large-scale protein-protein and protein-DNA interaction analyses, measurement of chromatin state, systematic RNAi and CRISPR mutational analysis, and high throughput functional analyses of genomic regulatory elements. By applying our methods to both closely and distantly related species, we are investigating how conserved molecular networks control basic developmental processes and how variation in molecular networks translates into variation in organismal phenotypes. We are also particularly interested in the transcriptional networks controlled by nuclear receptor proteins in development and disease. For example, we have produced genome-wide maps of the entire repertoire of nuclear receptors expressed in breast cancer cells, and this has led to the discovery of previously untargeted nuclear receptors that are promising drug candidates. We then test such candidates in mouse models, and we are attempting to ‘reverse engineer’ the nuclear receptor regulatory networks in breast cancer using a combination of genome-scale data generation, computational techniques and genomic engineering of cell lines and mice. We also have recently built novel algorithms for discovering tumor drivers and tumor risk factors from large-scale sequencing data, such as those available from The Cancer Genome Atlas. In those projects we have identified significantly co-occurring mutations and tested for genetic interactions in cell lines and in patient survival data, we have identified dozens of novel fusion genes and then synthesized them for testing in cell and mouse models, and we have systematically identified germline variants that may contribute to cancer risk and tested their functional roles using CRISPR engineered cell models.  Another focus of the lab is studying genetic regulatory programs that are highly conserved between fly and human. This has led to discoveries such as a role for the protein SPOP in both Drosophila embryogenesis and human kidney cancer, and to the identification of conserved targets of natural selection during adaptation to hypoxia (low oxygen) in both flies and humans. Related to this comparative work is our lab’s contributions to the ENCODE and modENCODE projects, where we have been systematically comparing the binding patterns of transcription factors genome-wide in flies, worms and humans. Our lab also contributes to the NIH GTEx and psychENCODE projects through our investigations of the relationship between genomic variation and variation in transcript and protein expression. Finally, we have recently embarked on an ambitious project in pancreatic cancer to co-analyze large numbers of tumor genomes, tens of thousands of electronic medical records, and literature databases to build predictive models of which patients might respond to which treatments. This work is facilitated by the use of patient-derived xenograft models, as well as mouse models developed using the CRISPR Cas9 system. Our goal is to develop algorithmic approaches to rapidly assess a tumor’s genomic and physiological state, then test drugs in mouse models that ultimately can be moved into patients.
