About Rosemary Braun  Lecture Tutorial

About Rosemary Braun 

Rosemary Braun is a computational biologist with an interest in the development of methods for integrative, systems-level analysis of high-dimensional ("big") *omic data. These methods incorporate bioinformatic information with experimental data to characterize the networks of interactions that lead to the emergence of complex phenotypes, particularly cancers.  Dr. Braun is an Assistant Professor of Biostatistics (Feinberg School of Medicine) and Engineering Sciences & Applied Mathematics at Northwestern University.


Title: Lively Networks

Many systems -- including living cells -- exhibit collective behaviors that emerge from complex networks of many interacting processes.  What can the "wiring diagram" of those interactions tell us about the dynamics of the system, and can we deduce the underlying network from the collective dynamics?  In this talk, I will discuss what we can learn about the dynamics of interacting systems from the topology of the underlying network of interactions.  I will introduce the formalisms of spectral graph theory and network filtration, and illustrate how these approaches can help us model how living systems respond and adapt to perturbations.


Title: Seeing the forest and the trees: multi-scale approaches for analyzing cancer omics data.

Advances in high-throughput "*omic" assays now make it possible to the molecular state of a sample in genome-wide detail, providing unprecedented opportunity to investigate disease mechanisms by simultaneously profiling thousands molecular markers per sample.  To date, however, most analyses of *omic data consider each marker independently and treat regulatory pathways as a "sum of their parts." By neglecting the network of interactions, such approaches can miss crucial multi--gene effects associated with disease.  This talk will present some recent techniques to incorporate pathway information into the analysis of high--dimensional *omic data.  By analyzing data at the systems level, the methods enable us to integrate disparate types of *omic data, make inferences about disease mechanisms, and distinguish sets of cumulatively deleterious alterations from those that compensate one-another to preserve the overall function of a pathway.  We will show how these analyses can overcome the high variability of *omics data to yield results that are more reproducible across studies, and demonstrate how these methods can be used to identify novel therapeutic and diagnostic targets.

About Tomasz Lipniacki

Dr. Tomasz Lipniacki is a professor and head of the department in the Institute of Fundamental Technological Research, Polish Academy of Sciences. He graduated from Department of Physics,  Warsaw University. Dr. Lipniacki works on cellular regulatory pathways governing responses to stress.  His lab combines stochastic modeling with single cell experiments aiming to elucidate cellular decision making in innate immune signaling. He analyzes how feedbacks and other nonlinear regulatory elements in noisy environments turn information into decision.


Lecture 1: Stochastic modeling of innate immune responses

I will start from deterministic and stochastic modeling of NF-κB pathway and proceed to our recent study in which we analyze cell fate decisions in intertwined NF-κB/IRF3 and STAT signaling pathways.

In first part I will show how noise and feedbacks lead to nearly all-or-nothing responses to small TNF doses that activate single or few receptors TNF receptors. Responses to such weak signals are enabled by the kinase cascade that works as nonlinear signal amplifier.

In the second part I will discuss cell fate decisions that arise in the crosstalk of three transcription factors and are coordinated by paracrine IFNβ signaling at the cell population level. In this example initial heterogeneities in expression of virus sensing proteins lead to formation of distinct subpopulations of cells.

Lecture 2: Cellular information processing for time-varying stimulation

Two important regulatory pathways of NF-κB and MAPK were found to transmit merely one bit of information about the level of constant stimulation with, respectively, TNF and EGF %((%1,2,3%))%. This somewhat surprising result may suggest that these pathways evolved to process analog inputs into physiologically interpretable binary outputs. Although being capable of transmitting a single bit about the stimulation dose, both NF-κB and MAPK pathways can respond in a pulsatory manner to the repeated pulses of the stimuli.

Based on computational model %((%4%))% we estimated MAPK channel information capacity (or simply bitrate), defined as maximal mutual information that can be transmitted over a sufficiently long time t, dived by t %((%5%))%. The MAPK pathway is capable of responding (by activation of kinase ERK) to short EGF pulses of period not shorter than T=60 minutes. As the response is nearly binary, one could expect that the information transmission rate is equal to the classical bandwidth, 1/T. We found however, that the upper bound on information transmission rate is substantially higher and can be achieved for sequences of EGF pulses with carrying frequency higher than 1/T. I will discuss this high-frequency coding/decoding for binary input sequences.

Nonlinear regulatory elements in signaling pathways

In the first part: In will discuss characteristic nonlinear regulatory elements that shape dynamic of regulatory pathways: stoichiometric saturation, negative and positive feedbacks, feedforwards, kinase cascades. We will analyze temporal dynamics associated with these elements, and learn how this dynamics can be predicted based on bifurcation diagrams. Next we consider three dynamically distinct combinations of positive and negative feedbacks.

In the second part we will look how these elements regulate behavior of regulatory pathways in the presence of noise, and in the case when the spatial aspects of the signaling are important. If time permits we will consider bistable, spatial stochastic systems.

Alexandra Jilkine is an Assistant Professor in the Department of Applied and Copmutational Mathematics and Statistics at the University of Notre Dame. Prof. Jilkine is a mathematical biologist, and her research interests include: mathematical modelling of cell lineages and optimal division patterns for delaying cancer, modeling feedbacks governing stem cell renewal and differentiation, and spatiotemporal behaviour of biochemical circuits.


Control of Cell Fraction and Population Recovery during Tissue Regeneration in Stem Cell Lineages

Multicellular tissues are continually turning over, and homeostasis is maintained through regulated proliferation and differentiation of stem cells and progenitors. Following tissue injury, a dramatic increase in cell proliferation is commonly observed, resulting in rapid restoration of tissue size. This regulation is thought to occur via multiple feedback loops acting on cell self-renewal or differentiation. Prior modeling studies of the cell lineage system have suggested that loss of homeostasis and initiation of tumorigenesis can be contributed to the loss of control of these processes, and the rate of symmetric versus asymmetric division of the stem cells may also be altered.

Here, we compare three variants of hierarchical stem cell lineage tissue models with different combinations of negative feedbacks and use sensitivity analysis to examine what are the possible strategies for the cells to achieve certain performance objectives. Our results suggest that multiple negative feedback loops must be present in the stem cell lineage the fractions of stem cells to differentiated cells in the total population as robust as possible to variations in cell division parameters, and to minimize the time for tissue recovery in a non-oscillatory manner. When one of these negative feedback loops on stem cell division been knocked out, most of the stem cell lineage population will be in the form of stem cells, suggestive of "precancerous" tissue. Furthermore, modeling suggests that positive feedback loops in stem cell homeostasis may also be required. We contrast and compare the differences between deterministic and stochastic versions of the models.

Tools for modeling optimal treatment schedules to delay cancer progression

Acquired drug resistance is an obstacle for the treatment of cancer. Throughout a tumor’s life, the possibility of genetic or epigenetic alterations may lead to a subclone resistant to the therapy provided. In some cases, additional therapies are possible to continue treatment. However, it’s been shown through modeling that resistance and tumor progression can be delayed by altering the schedule making use of pharmacokinetic parameters and tumor growth data to create an optimal dosing schedule where the drug concentrations may be under the maximum tolerated dose which is typically administered. We will explore the background tools used to create optimal dosing schedules which typically rely on time-inhomogeneous branching process models of growth and methods for elucidating data that can inform these models. An overview of topics will include the following for single drug and combination models:

  • Quick review of simulation of branching process models
  • Calculating the Probability of Resistance and Expected Number of Resistant Cells
  • Incorporating pharmacokinetic parameters into time-dependent branching process models
  • Choosing optimal schedules

The evolving landscape of genomic susceptibility to cancer

For many years the process of testing for genetic susceptibility to cancer was based on testing a limited number of patients for a limited number of genes. The limitations on patients was based on testing only those patients with a high likelihood of having genetic susceptibility to cancer (extensive family history, etc). The limitation on genes was imposed due to the cost of genetic testing and the uncertainty in evaluating genetic variants when found due to the lack of large population databases for comparisons. Over the last five years the cost of sequencing has plummeted and much larger databases of non-cancer patients who have undergone whole genome or whole exome sequencing (of all genes) are available. With these advances we are transitioning to doing comprehensive understanding of all cancer patients. These early studies have revealed surprising results including that approximately 10% of unselect adult or pediatric patients carry deleterious mutations in cancer susceptibility genes. We have also learned that our prior attempts to select which patients carry these mutations failed to identify about half of the patients with hereditary mutations. Thus, there is a significant need to adjust our approach and the way that we evaluate patients and the genomic data. We will discuss a number of these recent studies, some of the surprising results, e.g. adult breast cancer mutations in children with a variety of cancers and discuss the challenges interpreting many of these results.

Data Analysis for Biophysics: from writing down models to learning models from the data

Data analysis courses that go beyond teaching elementary topics such as fitting residuals are rarely offered to students in the physical sciences. Thus, dataanalysis, much like programming, is something often learned and improvised “on the job”. Yet, with an explosion of experimental methods generating large quantities of data, the community would benefit from a clear presentation of methods of data analysis many of which are straightforward to implement and would raise our community standard for how data is currently being treated. It is often not realistic to expect graduate or undergraduate students alike to take a course covering topics of statistics relevant to their discipline in the physical sciences without taking multiple prerequisites needed to follow the material presented in such courses. My goal here is therefore to provide an introduction to exciting new developments in data science, machine learning and statistics in a language accessible to physical scientists willing to learn the necessary programming and mathematics. In particular, we will discuss tools of maximum likelihood, Bayesian inference, computational statistics and Bayesian nonparametrics.


Novel Statistical Tools for Single Molecule Biophysics: A foray into Bayesian nonparametrics

One route to modeling biophysical dynamics involves the bottom-up, molecular simulation, approach. In this approach, approximate classical potentials are used to simulate short time local motions in order draw insight on dynamics at longer time and larger length scales. Here we take a different route. Instead we present a top-bottom approach to building models of single molecule conformational dynamics and diffusion. The approach we present exploits a novel branch of Statistics – called Bayesian nonparametrics (BNPs) – first proposed in 1973 and now widely used in data science as the important conceptual advances of BNPs have become computational feasible in the last decade. BNPs are new to the physical sciences. They use flexible (nonparametric) model structures to efficiently learn models from complex data sets. Here we will show how BNPs can be adapted to address important questions in biophysics directly from the data which is often limited by factors such as finite photon budgets as well as other fluorophore artifacts in addition to data collection artifacts (e.g. aliasing, drift). More specifically, we will show that BNPs hold promise by allowing complex spectroscopic time traces (e.g. smFRET, photon arrivals) or images (e.g. single particle tracking) to be analyzed and turned into principled models of single molecule motion – from diffusion to conformational dynamics and beyond.

A Novel Strategy to Accelerate the Modeling and Analysis of Complex Biological Systems

Although we have a well-defined concept of an organism’s genotype, its phenotypes – the biological functions implemented by its underlying biochemistry – are difficult to define and predict. We ultimately want to represent the phenotype by a mechanistic model that accurately describes the changes in the concentrations of the compounds under various conditions. The ‘architecture’ of a system can be inferred from high-throughput data, but numerous unknown kinetic parameters influence exactly how change in one concentration affects others. Often the phenotype becomes clear only when those parameters are known; even a simple model can exhibit many phenotypes given different parameter choices. Current approaches to determining phenotype thus focus first on finding parameter values for the underlying biochemistry, typically through a mixture of ad-hoc experimentation and computationally inefficient highdimensional numerical search. While these strategies have been used to fully characterize small systems in the pre-genomic era, a mechanistic understanding of systems, even of moderate size, derived from genotype data remains elusive. We propose a fundamental shift towards a post-genomic computational paradigm in which we first analytically determine the space of possible phenotypes for a given network architecture and then predict parameter values for their realization, predictions that can guide experimentation and further numerical analysis. This ‘phenotype-centric’ paradigm combines four innovations with the potential to accelerate our understanding of complex biological systems: (1) a rigorous mathematical definition of biochemical phenotypes, (2) a method for enumerating the phenotypic repertoire based on the biomolecular network architecture, (3) an integrated suite of computational algorithms for the efficient prediction of parameter values and analysis of the phenotypic repertoire, and (4) a userfocused environment for navigating the resulting space of phenotypes and identifying biologically relevant features. These innovations will facilitate deterministic and stochastic simulations that require parameter values, will accelerate both hypothesis discrimination in systems biology and the design cycle in synthetic biology, and will enable investigators to achieve predictive understanding of biomolecular phenotypes from genotype.

In the lecture, I will describe the underlying theory, review recent progress toward the realization of its potential, and outline some of the remaining challenges.

In the breakout session, I will work through a few specific applications, highlight areas of theory in need computer implementation, and explore connections to other modeling approaches and issues of scalability.
