"Combining Synthetic Biology with Lessons from Big Data"

Understanding how gene expression is programmed into the DNA sequences in our genomes is a central objective in human genetics. While challenging, the task of unraveling a 3 billion base code is not completely unprecedented. Over the past decade, computer scientists working in natural language processing have made immense progress using algorithms that learn from enormous data sets. Inspired this success of “big data” in traditional machine learning areas, we have applied synthetic biology to generate massive datasets profiling the biological function of many different DNA sequences. As a proof of principle, we have measured the alternative RNA splicing patterns of over 250,000 fully synthetic sequences—an order of magnitude more than exists in the natural genome. From these data, we have built a predictive sequence model of alternative splicing that outperforms the state of the art algorithms.

Alex Rosenberg is a 5th year graduate student in Georg Seelig's lab. His research combines machine learning and the development of new high throughput methods to understand gene regulation.

"Modeling tuberculosis, from cells to populations"

abstract:
Tuberculosis continues to afflict millions of people and causes over a million deaths a year worldwide. Multi-drug resistance is also on the rise, causing concern among public-health experts. This talk will give an overview of my work on modeling tuberculosis at various scales. On the cellular side I will describe models of the metabolism of M. tuberculosis, where insights from duality led to a consistent analysis of existing models, a systematic method for reconciling discrepant models, and the identification of putative drug targets. On the population side I will describe models of strain evolution, where a new metric combined with an optimization-based approach resulted in an accurate classification of complex infections as originating from mutation or mixed infection, as well as the identification of the strains composing these complex infections.

Title: Patient Network Fusion: a fast and effective method to aggregate multiple data types

Abstract: Recent technological advances have made large-scale collection of genomic, transcriptomic and epigenetic data rapid, cost-effective and widely available. Combining these multiple data types in a way that maximizes our knowledge of the disease or biological process in question is currently a major bottleneck. In this talk I will discuss our new approach that integrates multiple types of patient data by building similarity networks for each available data type and then combining them into a single network using Patient Network Fusion (PNF). PNF takes advantage of complementary information in different types of data, does not require gene pre-selection, and is fast and robust to different types of noise. We apply our method to a variety of biological datasets derived from Glioblastoma Multiforme (GBM) patients and show that our method both recapitulates prior knowledge and produces new biological insights. I will illustrate PNF's superior performance as compared to single data type analysis and established integrative approaches with regards to survival subtype profiles and cluster coherence in a total of five cancers. If time permits, I will discuss the potential of this new technology for new applications and the impact on precision medicine.

"Bayesian Models for Genome-wide Analysis of Phylogenies and Populations"

Gene phylogenies provide a rich source of information about the way evolution shapes genomes, populations, and phenotypes.  In addition to substitutions, evolutionary events such as gene duplication and loss play a major role in gene evolution, and many phylogenetic models have been developed in order to reconstruct and study these events.
However, these models typically make the simplifying assumption that population-related effects such as incomplete lineage sorting (ILS) are negligible.  While this assumption may have been reasonable in some settings, it has become increasingly problematic as increased genome sequencing has led to denser phylogenies, where effects such as ILS are more prominent.  To address this challenge, we have developed a new probabilistic model, DLCoal, that defines gene duplication and loss in a population setting, such that coalescence and ILS can be directly addressed. Interestingly, this model implies that in addition to the usual gene tree and species tree there exists a third tree, the locus tree, which will likely have many applications.  Using this model, we have developed the first general reconciliation method that accurately infers gene duplications and losses in the presence of ILS, and we show its improved inference of orthologs, paralogs, duplications, and losses for a variety of clades, including flies, fungi, and primates.  Also, our simulations show that gene duplications increase the frequency of ILS, further illustrating the importance of a joint model.

We have also developed a new method for reconstructing the history of genomic regions across several individuals within a single species.
Such histories, called Ancestral Recombination Graphs (ARGs), if efficiently inferred can have many applications within population genetics, ranging from detecting selection to characterizing demography.  Although many methods exist for sampling ARGs, they are often computationally intensive.  Our approach is to build upon the Sequentially Markov Coalescent model to develop a new Gibbs sampling method that can work on genomic scales.  Our sampling method is based on the idea of sampling an ARG of n chromosomes (haplotypes) by conditioning on a given ARG of n-1 chromosomes.  We call this "threading" a chromosome into an ARG, and this new threading method will likely have many applications.

Excavating human nuclear mtDNAs

NUMTs (Nuclear mtDNA), are partial copies of the mitochondrial genome found in the nuclear genome.  They are sometimes referred to as molecular fossils, and, due to the higher mutation rate of mtDNA, can in some cases be more similar to parts of our ancestral mtDNA than our extent mtDNA genome is.

The existence of NUMTs has been known for decades and many informatics studies on NUMTs have attempted to elucidate the characteristics of their insertion sites.  By showing that NUMTs are typically very clean insertions with only minimal deletion or duplication of the surrounding nuclear DNA, these studies have lead to a consensus opinion that most NUMTs are likely inserted as filler DNA via NHEJ (Non-Homologous End Joining).

Previous informatics studies have not shed much light upon the preferred insertion sites of NUMTs.  Most of them conclude that NUMT insertion is random -- except for contradictory reports that NUMTs correlate positively, or negatively, with retrotransposons.
Fortunately, by employing more careful methodology, we were able to discover several as yet undiscovered aspects of this phenomenon.

We found that inferred NUMTs insertion sites strongly correlate with predicted physical properties of DNA (curvature and bendability) and
A+T rich oligomers.  Moreover, recently inserted NUMTs correlate
strongly with nucleosome free regions as measured by DNase-seq and FAIRE-seq.  We also firmly establishing that NUMTs do indeed tend to co-occur with retrotransposons.  As for the source mtDNA which is copied to create NUMTs, we find that part of the mtDNA D-loop region is very seldom copied.

Relating these facts to concrete hypotheses regarding the mechanism of NUMT insertion proved very challenging, but also fascinating, as it touched upon diverse topics in molecular biology: from retrotransposon activity and DNA repair to evolutionary conservation of chromatin structure and the packaging of mtDNA.

"Network-based Phenome-Genome Association Analysis"
12:00, Foege Auditorium

Abstract:
In the past decade, genome-wide studies of disease-gene associations enabled by the high-throughput genomic technologies revealed many disease causal genes. Driven by the determined associations, a promising next step is to perform large-scale association analysis between all genes and the complete collection of phenotypes (phenome). In this talk, I will introduce our research work on three aspects of phenome-genome association analysis, 1) disease gene prioritization which determines candidate disease genes for a single query disease phenotype; 2) phenome-genome association prediction which reconstructs the complete phenotype-gene associations; and 3) module-based phenome-genome analysis which co-clusters phenotypes and genes, and simultaneously identifies associations between the detected phenotype clusters and gene clusters. We designed subnetwork-based label propagation, bi-random walk and regularized non-negative matrix tri-factorization for the three problems, respectively. Promising results were observed in the cross-validation experiments on the disease phenotype-gene associations in OMIM. Examples of interesting findings in neurological, psychiatric and gastrointestinal disease phenotypes will also be discussed.

"The DNA programs controlling splicing"
Foege Auditorium

Abstract:
Viewing the genome as the software that controls the development of cells, tissues and organisms, my group uses high-throughput expression data and matched genome data to infer the genetic code that governs gene expression. We are currently focussing on alternative splicing, which cells use to dynamically modify over 90% of human genes, such as genes critical for synaptic plasticity. Unknowns such a trans-factor expression levels, protein binding sites, the effects of RNA secondary structures, and transcription rate-dependent effects are computationally inferred. We find that the resulting code can be used to reveal novel regulatory mechanisms, predict expression patterns under previously unexamined conditions, and simulate the effects of disease mutations with high accuracy.

"Identification of rare alleles and their carriers using compressed se(que)nsing"

Abstract: Identification of rare variants by resequencing is important both for detecting novel variations and for screening individuals for known disease alleles. New technologies enable low-cost resequencing of target regions, although it is still prohibitive to test more than a few individuals. We propose a novel pooling design that enables the recovery of novel or known rare alleles and their carriers in groups of individuals. The method is based on a Compressed Sensing (CS) approach, which is general, simple and efficient. CS allows the use of generic algorithmic tools for simultaneous identification of multiple variants and their carriers. We model the experimental procedure and show via computer simulations that it enables the recovery of rare alleles and their carriers in larger groups than were possible before. Our approach can also be combined with barcoding techniques to provide a feasible solution based on current resequencing costs. For example, when targeting a small enough genomic region (~100 bp) and using only ~10 sequencing lanes and ~10 distinct barcodes per lane, one recovers the identity of 4 rare allele carriers out of a population of over 4000 individuals. We demonstrate the performance of our approach over several publicly available experimental data sets, including the 1000 Genomes Pilot 3 study.
We believe our approach may significantly improve cost effectiveness in future Genome Wide Association Studies, and in screening large DNA cohorts for specific risk alleles.

“Whole Genome Expression Quantitative Trait Loci (eQTL) Analysis of Arabidopsis”
3:30, Foege Auditorium

Abstract:

There is increasing interest in understanding the molecular basis of complex traits. Initially, the genetic dissection of quantitative traits involved measurements of gross phenotypes.  Most recently, the underlying mechanisms of inheritance have been studied through various approaches that are supported by modern technological and methodological advances, namely quantitative trait locus/loci (QTL) analysis and mutant analysis in genetics; genome sequencing and gene expression analysis in genomics; and protein structure analysis and protein assay in proteomics. Since each technology and approach focuses on specific pieces of the larger, poorly understood systems biology, the challenge is to integrate these different types of information to elucidate the genetic architecture of complex traits.   To address one of these challenges we have combined QTL analysis with microarray analysis to characterize the genomic architecture that controls quantitative traits.  Using Affymetrix technology and 211 individuals from a segregating Arabidopsis population, the transcript variation (i.e., expression level polymorphisms, ELPs) of 22,810 genes, in both control and treatment conditions, provide data for mapping expression QTL (eQTL).  Results from our statistical analysis of the entire genome reveal both cis- and trans-eQTL under both control and treatment conditions.  The statistical methodology developed for this type of experiment will be presented for a directed analysis of SA-inducible secretory genes controlled by NPR1.

Abstract:
I will describe three recent comparative genomics projects, including two of mammals and one of plants. The first is a large-scale effort, carried out as part of the Mammalian Gene Collection (MGC) project, to identify human genes not yet in the gene catalogs. Our approach was to produce gene predictions by algorithms that rely on comparative sequence data but do not require direct cDNA evidence, then to test predicted novel genes by RT-PCR. This work led to the identification of more than 2000 novel exons corresponding to an estimated ~500 genes, including >160 that were completely absent from the gene catalogs. The second project is a comprehensive analysis of positively selected genes (PSGs) in mammals based on the six high-coverage eutherian mammalian genome assemblies now available. Compared with previous genome-wide scans for PSGs, the increased phylogenetic depth of this data set results in substantially improved statistical power, and permits several new lineage- and clade-specific tests to be applied. Several hundred apparent PSGs were identified, and a detailed analysis was performed of their selection histories (evolutionary patterns of selection and nonselection), the functional categories and pathways to which they belong, and their expression patterns. The third project is an attempt to apply tools and techniques developed for comparative genomics of mammals to a group of plants showing similar levels of genomic divergence. This project involved the generation and analysis of sequences for a ~100kb conserved syntenic segment (CSS) in the genomes of five members of the agriculturally important plant family Solanaceae. Our analysis suggests that, as in mammals, a large fraction of noncoding bases in these genes is under selection, and it sheds light on the dates of divergence if these species. Together, these three projects illustrate the power of comparative genomics in characterizing evolutionary dynamics, selection pressures, and genomic function.

“Abuse of the Mode and an Ensemble Alternative”

Abstract:
Advances in data collection technologies have rendered increasingly large data sets available for analysis.  While the emergence of such large data sets would seem to lead to increasingly more precise estimates of parameters, paradoxically just the opposite seems to becoming increasingly common. This paradoxical circumstance has emerged because these technologies have simultaneously opened opportunities to draw inferences on previously unanswerable high dimensional questions.  For decades optimization procedures such as maximum likelihood, minimum free energy, and MAP estimators, have been employed as the major tool of most inference procedures. It has been clearly recognized for some time now that the favorable properties of optimization based inferences rest on an asymptotic foundation that requires the data to grow in comparison with the number of unknowns. Nevertheless, optimization very often continues as the method of choice even when these supporting conditions are not present and even when the most probable solution has a probability of 10-10 or less. Genomics and computational molecular biology are among the more predominate fields experiencing the duality of the growth in data resources and inference expectations.  In fact, prediction and inference of high dimensional objects are now arguably the most important activities in these allied new biological fields, and the inspiration for this paper.  RNA secondary structure prediction offers a very special lens to examine the untoward consequences of the reliance on the mode in high dimensional inferences because polynomial time algorithms are available to comprehensively characterize the space of solutions, and a references set of structures is available for the comparison of alternative prediction methods.  Through this lens we will examine these untoward effects, consider their boarder implications, and present alternative "ensemble based" centroid estimators.  Using a model identical to the well know Mfold model, we find that centroid estimators both better represent the posterior space and improve positive predictive values of the reference set predictions by 30% while improving sensitivity by 3% compared to Mfold predictions that minimize free energy.

"Graphs, Colorings and Beyond in Comparative Genomics"

Abstract:
Comparative genomics seeks to explore characteristic patterns of a set of
organisms by comparing common features of the given organisms. Computational
methods are a significant part in this type of discipline. In this talk I will
describe the use of colored graphs to solve two problems in comparative
genomics:

1. Micro-indels are small insertion or deletion events (indels) that occur
during genome evolution. The study of micro-indels is important, both in order
to better understand the underlying biological mechanisms, and also for
improving the evolutionary models used in sequence alignment and phylogenetic
analysis. The inference of micro-indels poses a difficult computational
problem, and is far more complicated than the related task of inferring the
history of point mutations. We introduce the concept of indel history, a tree
alignment based approach that is suitable for working with multiple genomes,
which enables us to arrive at some interesting computational and biological
findings.

2. Horizontal gene transfer (HGT) is the transfer of genetic material from one
lineage to another. HGT plays a major role in bacteria's genome diversification
as well as their ability to develop resistance to antibiotics. This mechanism
cannot be represented by the traditional tree-like evolution rather as a
network. We show new results, both combinatorial and statistical, improving
significantly over current approaches and enable us to analyze real biological
data sets.

"Computational Biology, Molecular Architecture and Transcription"

Abstract:
Elucidating the underlying causes of sequence variability in proteins is an important goal in modern biology. Sophisticated statistical analyses geared toward partitioning sequence variation into its underlying causal components are difficult because of the so-called “sequence metric problem.” That is, biosequences are comprised of alphabetic codes that have no underlying natural metric. Recently, we offered a solution to this problem (PNAS 102:6395-6400, 2005) that permits these alphabetic codes to be transformed into highly interpretable numerical values. These new values were derived from multivariate statistical analysis of a large suite of amino acid physiochemical attributes. I will briefly describe this new approach and then introduce some applications using the basic helix-loop-helix (bHLH) proteins as exemplars. As time permits, I will discuss this approach and partitioning amino acid covariation, elucidating the molecular architecture of DNA binding and dimerization, and understanding those amino acids involved in enhanced binding specificity.

"Comparative mammalian genomics: models of evolution and detection of functional elements"

Abstract:
Having the complete genomes of multiple species is causing sweeping changes in biology. Comparative sequence analysis is leading to new insights about the evolutionary forces that have shaped present-day genomes and is enabling previously unknown functional sequences to be identified and characterized. Comparative methods hold particular promise for mammalian and other vertebrate genomes, which--because of their size and complexity, and because of other obstacles to experimental study--have been more difficult to approach experimentally than the genomes of simpler organisms such as flies and nematodes.

In this talk, I will discuss both recent methodological advances in comparative sequence analysis and scientific insights gained from genome-wide surveys conducted with these methods. The main theme of the talk will be using evolutionary models to help shed light on sequence function. Three particular problems will be discussed: the identification of evolutionarily conserved elements, modeling context- or neighbor-dependent substitution, and the identification of evolutionarily conserved protein-coding exons. These problems have been addressed using phylogenetic hidden Markov models (phylo-HMMs), statistical models that describe both the process of nucleotide substitution at individual sites in a genome and how this process changes from one site to the next.

Using a phylo-HMM-based program called phastCons, we have conducted a comprehensive search for conserved elements in vertebrate genomes. I will discuss the results of this search and of parallel searches in Drosophila, Caenorhabditis, and Saccharomyces genomes. Particular attention will devoted to the most highly conserved of the elements identified in vertebrates, which appear to be associated with both transcriptional and post-transcriptional regulation and which show significant statistical evidence of an enrichment for RNA secondary structure. In separate work, another phylo-HMM-based program called ExoniPhy has been used to predict about 170,000 protein-coding exons conserved in the human, mouse, and rat genomes, corresponding to an expected 20,400 genes. Of these, about 23,000 predicted exons (2,800 genes) are not represented in sets of known genes. Preliminary experimental (RT-PCR) results indicate that the false positive rate of these predictions is quite low (<30%).

"Deciphering rules governing enhancer functional evolution"

Abstract:
Lack of knowledge about how regulatory regions evolve in relation to their structure-function may limit the utility of comparative sequence analysis in deciphering cis-regulatory sequences. To address this we applied reverse genetics to carry out the first functional genetic complementation analysis of a eukaryotic cis-regulatory module - the even-skipped stripe 2 enhancer - from four Drosophila species. The functional evolution of this enhancer is non-clocklike: important functional differences have evolved between closely related species that are not found between distantly related species. We can attribute the functional conservation between distantly related species to evolutionary convergence rather than evolutionary stasis. Functional divergence of the stripe2 enhancer between closely related species is attributable to differences in activation levels rather than spatio-temporal control of gene expression. Our findings have implications for understanding enhancer structure-function, mechanisms of speciation, and computational identification of regulatory modules.

website

Abstract:
I will describe and demonstrate the course project tackled by undergraduate students in last spring's inaugural Computational Biology Capstone Course, CSE 490MT. The goal of the project was to write software that starts from a single microbial gene of interest, finds a large collection of orthologous genes from multiple microbes, and uses this collection to identify evolutionarily conserved motifs in their regulatory regions. These motifs are good candidates to be functional regulatory elements. Such a tool, if done well, could be very useful for working microbiologists.

"Anatomy, Biomedicine and Computing: the ABC's of Informatics in Cancer Treatment"

Abstract:
The explosive growth in the application of computing to medical and health care research and practice has been most visible in computerized medical record systems, web based medical knowledge resources and biomolecular data such as GENBANK. By contrast, the field of radiation therapy for cancer has had computing as an integral part of research and practice since the mid-1960's. Designing radiation treatments is typically done with an interactive graphic software system called a "radiation therapy planning", or RTP, system. The design of RTP systems requires solving difficult graphic visualization problems, careful attention to user interface design, efficient numerical computation, and advanced networking. In addition, as these systems can grow to large size (from 75,000 up to a million lines of code), they provide an industrial strength trial opportunity for new ideas in software engineering. Finally, the design process itself, largely done by human experts, may be automated by creating computational models of human anatomy, tumor biology and radiation machinery. The talk will include an interactive demonstration of the Prism RTP system developed at the University of Washington, and will conclude with a short summary of the UW Biomedical and Health Informatics program, a larger context for such biocomputing research.
