Title: Diagnosis of Glioma Tumors Using Circulating Cell-Free DNA

Abstract: Gliomas are the most frequent brain tumors, making up about 30% of all brain and central nervous system tumors, and 80% of all malignant brain tumors. Diagnosis of different glioma tumor types and their tumor grade is an essential step to suggest a right treatment for the glioma patients. Existing standard diagnostic technique for glioma tumor includes tissue biopsy, which is a highly invasive and hence a risky technique for the patient’s survival. ‘Liquid biopsy’ is a new and recently developed non-invasive cancer diagnostic technique. This technique includes collection of blood or urine samples and diagnosis of cancer based on analyzing molecular bits or cancer cells that are released from tumor tissue into the blood or urine system. Circulating cell-free DNA (cfDNA) fragments is one those molecular bits that are released into the bloodstream after rapid apoptosis or necrosis of the tumor cells in the cancer patients. Our goal is to do comprehensive study between distinct types of glioma cancer tumors and cfDNA of the respective patients, to elucidate the scope of cfDNA in liquid biopsy technique for glioma diagnosis. We have successfully detected glioma specific mutations such as IDH1, IDH2, PDGFRA, NOTCH1, PIK3R1 and TP53, from cfDNA isolated from the plasma of glioma patients and could relate these mutations to the different tumor grades of glioma. Moreover, we have identified unique gene-gene fusions that provide a personalized drug response to glioma treatment. Our study may help in developing liquid biopsy technique for glioma tumor diagnosis and in its prognosis for monitoring the glioma treatment by non-invasive approach, and will eventually help physicians to decide on the right treatment while bypassing the existing ''wait-and-see' approach of treatment monitoring.

Title: The Metabolic Marketplace: How the cellular economy of supply and demand is regulated
Abstract: A central tenet of systems biology is that organisms, cells, genes and proteins are complex structures whose relationships and properties are largely determined by their functional organisation. In terms of functional organisation cellular metabolism can be regarded as a chain of coupled factories: a catabolic factory transforms nutrients into carbon skeletons and captures chemical energy and reducing power. These catabolic products serve as input to an anabolic factory that synthesizes the building blocks for macromolecular syntheses (amino acids, nucleotides, simple lipids, etc.). The factories for protein, polynucleotide, complex carbohydrate and lipid synthesis form the end of the chain and lead to growth. I show how this view of the functional organisation of the cell underlies a quantitative formalism and a general theory for understanding the cell as an integrated molecular economy of coupled supply and demand systems that have evolved regulatory mechanisms that enable them to fulfil specific functions such as control of flux or homeostatic maintenance of metabolite concentrations.
Jan-Hendrik (Jannie) Hofmeyr is Emeritus Professor of Biochemistry and has been a member of the Biochemistry Department at the Stellenbosch University since 1975. He obtained his Ph.D. in 1986 at the University of Stellenbosch. His research of the past 40 years has been in the fields of metabolic control analysis and computational systems biology where his main focus has been the understanding of the regulatory design of metabolism. He also co-directed the Centre for Complex Systems in Transition where an additional research focus was the functional organisation that underlies cellular self-fabrication. He is a Fellow and was President of the Royal Society of South Africa, and is a member of the Academy of Science of South Africa.

# Speaker: Prof. Olivier Gandrillon, Ecole Normale Superieure de Lyon at IST 13:00 Hour
Toward a dynamical network view on a differentiation process
A recent view emerged that stochastic dynamics governing the switching of cells from one differentiation state to another could be characterized by a peak in gene expression variability at the point of fate commitment. We have tested this hypothesis at the single-cell level by analyzing primary chicken erythroid progenitors through their differentiation process and measuring the expression of selected genes at six sequential time-points after induction of differentiation. In contrast to population-based expression data, single-cell gene expression data revealed a high cell-to-cell variability, which was masked by averaging. Shannon entropy was used as as a measure of the cell-to-cell variability in gene expression. Entropy values showed a significant increase, reaching a peak between 8 and 24 h, before decreasing to significantly lower values. We observed that the previous point of maximum entropy precedes an irreversible commitment to differentiation between 24 and 48 h. In conclusion, when analyzed at the single cell level, the differentiation process looks very different from its classical population average view. New observables (like entropy) can be computed, the behavior of which is fully compatible with the idea that differentiation is not a “simple” program that all cells execute identically but results from the dynamical behavior of the underlying molecular network.

Information Theoretic Multivariate Dependence Analysis of HLA Immune-gene Regulation
Cell surface expression of Human Leukocytic Antigen (HLA) plays a significant role in immune recognition. HLA molecules are classified into two – class I and class II. In different cancers including leukemia, HLA (both class I and II) down-regulation is frequently reported. Regarding its regulation, different transcription factors (TFs) are responsible for its constitutive expression; however, it is also regulated by several inducible TFs. Using 1st order information theory based analysis for HLA and its associated TFs (human) gene expression data reveals that RFXB, an inducible controlling TF plays a major role in both myeloid and lymphoid types of leukemia; however, in lymphoid leukemia CREB1, another inducible TF may play an important role. Application of MaxEnt based multivariate dependence information theory for higher order analysis confirm the same finding along with an indication of the regulatory role of another combination of two TFs namely CIITA and IRF1 for myeloid type leukmic cells. However through this analysis no alteration is noted for HLA class II gene regulation.
Bio-sketch: Dr. Bishwajit Das, is an Investigator of SSBTR. He received his Ph.D. degree in 2021 from West Bengal State University. The field of his research is to understand HLA gene regulation in different non-communicable complex diseases by using different quantitative and analytical methods.

Title :
Reconstructing cell phenotypic transition dynamics from single cell data
Abstract :
Recent advances in single-cell techniques catalyze an emerging field of studying how cells convert from one phenotype to another, i.e., cell phenotypic transitions (CPTs). Two grand technical challenges, however, impede further development of the field. Fixed cell-based approaches can provide snapshots of high-dimensional expression profiles but have fundamental limits on revealing temporal information, and fluorescence-based live cell imaging approaches provide temporal information but are technically challenging for multiplex long- term imaging. My lab is tackling these grand challenges from two directions, with the ultimate goal of integrating the two directions to reconstruct the spatial-temporal dynamics of CPTs. In one direction, we developed a live-cell imaging platform that tracks cellular status change in a composite multi-dimensional cell feature space that include cell morphological and texture features readily through fluorescent and transmission light imaging. We applied the framework to study human A549 cells undergoing TGF-β induced epithelial-to-mesenchymal transition (EMT). In another direction, we aim at reconstructing single cell dynamics and governing equations from single cell genomics data. We developed a procedure of learning the analytical form of the vector field F(x) and the equation dx/dt = F(x) in the Reproducing Kernel Hilbert Space. Further differential geometry analysis on the vector field reveals rich information on gene regulations and dynamics of various CPT processes.

After being a postdoc researcher in theoretical biophysics at UC Berkeley and an independent fellow at Lawrence Livermore National Laboratory, he assumed his first faculty position at Virginia Tech, then moved to University of Pittsburgh in 2015. Currently Dr Xing is an Associate Professor in the Computational and Systems Biology Department, School of Medicine, a founding member of Center for Systems Immunology, and an affiliated faculty member of Department of Physics, University of Pittsburgh. He is also an affiliated member of University of Pittsburgh Hillman Cancer Center. Dr Xing’s research uses statistical and chemical physics, dynamical systems theory, mathematical/computational modeling in combination with quantitative measurements to study the dynamics and mechanics of biological processes. Recently his lab focuses on reconstructing information of cell phenotypic transition dynamics from live cell time-lapse images and snapshot high-throughput single cell data. Another related direction is to study how three-dimensional chromosome structure and dynamics, epigenetic modification, and gene regulation are coupled.

Title :
Systems biology of cancer metastasis: how do cancer cells coordinate, communicate, and cooperate?

Abstract : Metastasis (the spread of cancer cells from one organ to another) and therapy resistance cause above 90% of all cancer-related deaths. Despite extensive ongoing efforts in cancer genomics, no unique genetic or mutational signature has emerged for metastasis. However, a hallmark that has been observed in metastasis is adaptability or phenotypic plasticity – the ability of a cell to reversibly switch among different phenotypes in response to various internal or external stimuli. Phenotypic plasticity has also been recently implicated in enabling the emergence of resistance for many cancers across multiple therapies. However, a mechanistic understanding of these processes from a dynamical systems perspective remains incomplete. This talk will describe how mechanism-based mathematical models for phenotypic plasticity can enable our improved understanding of cellular decision-making at individual and population levels from these perspectives: a) Multistability (how many cell states exist en route?), b) Reversibility (do cells come across a ‘tipping point’ at specific time and/or dose of inducers beyond which they do not revert?), and c) Cell-cell communication (how do cells affect tendency of their neighbors to exhibit plasticity?). Collectively, our work highlights how an iterative crosstalk between mathematical modeling and experiments can both generate novel insights into the emergent nonlinear dynamics of cellular transitions and uncover previously unknown accelerators of metastasis and therapy resistance.

# Speaker: Dr. Heiko Enderling, H. Lee Moffitt Cancer Centre & Research Institute, at IST 17:30 Hour

Title: Integrating Computer Modeling of Cancer into Patient-specific Clinical Decision Making
In close collaboration with experimentalists and clinicians, mathematical models that are parameterized with experimental and clinical data can help estimate patient-specific disease dynamics and treatment success. This positions us at the forefront of the advent of ‘virtual trials’ that predict personalized optimized treatment protocols. I will discuss a couple of different projects to demonstrate how to integrate calculus into clinical decision making. First, we show that a mathematical model can be calibrated from early treatment response dynamics in patients undergoing hormone therapy for prostate cancer. The learned model dynamics can then be used to forecast responses to subsequent treatment, and identify high risk patients who would benefit from concurrent therapies. In a second example, I will discuss how the pre-treatment tumor-immune ecosystem can be predictive of radiotherapy outcome, and how we can prospectively simulate treatment response dynamics to identify patient candidates for radiation dose escalation when needed, and treatment de-escalation without jeopardizing outcomes.

A System Biology Based Dynamic Model to Limit Uncertainty in Cancer Treatment
In present cancer treatment scenario different chemotherapeutic strategies like Maximum Tolerable Dosing (MTD), Metronomic Chemotherapy (MCT), Antiangiogenic (AAG) drug, Hematopoietic stem cell transplantation are available; however, the selection of the best therapeutic strategy for an individual patient at any particular stage of disease remains uncertain till now. Several analytical models are proposed for each of the chemotherapeutic strategies; however, no single analytical model is available that can make a comparative assessment of the long-term therapeutic efficacy among these strategies towards patient specific manner. To address this issue we developed a composite synergistic system (CSS) model. Here we have synergized the output of two models. One is based on fluid dynamics (FD) principle and another is based on vasculature growth (VG). In this developed model considered model variables are helpful for fitting of initial clinical data of individual clinical cases and successive model simulation runs may help in making therapeutic decision/prediction. Again tracking tumor growth at a regular interval of time is possible by matching the simulation output with available clinical techniques like MRI or simple blood testing. Such model may help the clinician to overcome the uncertainty in therapy design at an individual patient level.

# Speaker: Dr. Igor Balaz, University of Navi Sad at IST 15:00 Hour.
Artificial Intelligence and Multiscale Modeling of Tumor Treatments
From the perspective of systems biology tumor can be regarded as a complex adaptive system. It is a nonlinear system, composed of a number of dynamically interacting elements with complex feedbacks between them. To model such systems multiple scales should be taken into account. Molecular scale simulations can give us insight into structural, thermodynamic, kinetic and other properties of applied drugs and how those drugs interact with cell membrane and receptors. At the cellular scale, pharmacodynamics modeling simulates the efficacy and toxicity of drugs. At the tumor scale, we need to integrate findings from the molecular and cellular scale simulations with the heterogeneous and adaptable tumor structure. To model tumor adaptive dynamics and the resulting emergence of treatment resistance, we should incorporate individualized genotype and phenotype data. Finally, at the organism scale, we should use integrated PK/PD approaches to model bio-distribution and clearance of drugs, as well as whole-body physiologically based pharmacokinetic models (PBPK). The set of all possible configurations of such modeling effort is enormous. Computationally investigating all of them is not feasible approach. However, with Artificial Intelligence we can speed-up and automate the search for optimal treatment strategy. In this webinar we will discuss strategies for developing such multiscale modeling platform and how it can be integrated with artificial intelligence.
Dr. Igor Balaz is an Assistant Professor at the University of Novi Sad, Serbia. He runs a computational biophysics lab in targeting the systems biology of cancer. The work of his team blends nanomedicine, molecular modeling, mathematical modeling and artificial intelligence to search for novel drug delivery systems. He leads two multinational European projects on the use of nanomedicine in cancer treatment: EVO-NANO (Evolvable platform for programmable nanoparticle-based cancer therapies) and PACE (Platform for Rapid Development of Personalized Nanomedicine Drug Delivery Systems).

Title: Machine Learning for Designing Hard Tissue Prostheses
To improve the performance of the orthopedic and dental implants, i.e. to improve several properties simultaneously, the constituent biomaterials properties as well as implant structure needs to be designed judiciously. The choice of the parameters for achieving optimum performance of the systems is difficult to arrive experimentally, as the process becomes expensive and laborious. In silico approaches hold promise for searching the solutions for achieving the target performance. Among the many approaches of designing materials and structures for protheses computationally, machine learning attempts to map the hidden relationship between the variables of complex, nonlinear systems using available information of the system in a high-throughput, statistically robust, and yet physically meaningful manner. Machine learning tools, e.g. artificial neural network and neuro-fuzzy inference systems are increasingly used in the domain of informatics-based design of implants and biomaterials. In a prescriptive analytics approach for improving several properties together, many of them having conflicting objectives, the developed models are used as objective functions for optimization with genetic algorithm used in single as well as multi-objective mode.
