Breast cancer, with an alarming incidence rate throughout the globe, has attracted significant investigations to identify disease specific biomarkers. Among these, oestrogen receptor (ER) occupies a central role where overexpression is a prognostic indication for breast cancer. The cross-talk between the responsible contenders of ER-associated genes potentially play an important role in the disease aetiology. Investigation of such cross talk is the focus of this thesis.

In order to understand biochemical networks we need to know not only how their parts work but also how they interact with each other. The goal of systems biology is to look at biological systems as a whole to understand how interactions of the parts can give rise to complex dynamics. In order to do this efficiently, new techniques have to be developed. This work shows how tools from mathematics are suitable to study problems in systems biology such as modeling, dynamics prediction, reverse engineering and many others.

Abstract:
The field of Synthetic Biology seeks to develop engineering principles for biological systems. Modular biological parts are repurposed and recombined to develop new synthetic biological devices with novel functions. The proper functioning of these devices is dependent on the cellular context provided by the host organism, and the interaction of these devices with host systems. The field of Systems Biology seeks to measure and model the properties of biological phenomena at the network scale. We present the application of systems biology approaches to synthetic biology, with particular emphasis

Abstract:
Systems biology is a comprehensive quantitative analysis of the manner in which all the components of a biological system interact functionally along with time. Mathematical modeling and computational methods are indispensable in such kind of studies, especially for interpreting and predicting the complex interactions among all the components so as to obtain some desirable system properties. System dynamics, system robustness and control method are three crucial properties in systems biology. In this thesis, the above properties are studied in four different biological systems. The ou

Abstract:
The evolution of a genome is shaped by spatial interactions at multiple scales. At the angstrom level, structural constraints on both RNA molecules and proteins contribute to the evolution of a gene sequence. Such optimized genes are weaved together in a particular order, out of a near-infinite number of combinations, to result in a genome. The fate of a genome is intricately linked to the evolutionary fate of its host organism; in turn, the fate of an organism is governed by where it resides in space. In this dissertation, I investigate how structure shapes the evolution of a gene, genome con

Abstract:
This dissertation develops algebraic theory for discrete models in systems biology. Many discrete model types can be translated into the framework of polynomial dynamical systems (PDS), that is, time- and state-discrete dynamical systems over a finite field where the transition function for each variable is given as a polynomial. This allows for using a range of theoretical and computational tools from computer algebra, which results in a powerful computational engine for model construction, parameter estimation, and analysis methods. Formal definitions and theorems for PDS and the concept of

Abstract:
Temperature is arguably the leading factor that drives adaptation of organisms and ecosystems. Remarkably, many sister species share the same habitat because of their different temporal or micro-spatial thermal adaptation. In this PhD, the underlying molecular mechanisms of the adaptation of closely related species to different temperatures are sought. A thermodynamic analysis was applied to a genome-scale metabolic model of S. cerevisiae at warm and cold temperatures to identify thermo-dependent reactions. Gene Ontology (GO) analysis of predicted cold-dependent reactions found that redox reac

Abstract:
A fundamental property of living cells is the ability to sense and respond appropriately to changing environmental conditions. In budding yeast (Sacharomyces cerevisiae), changes in extracellular osmotic conditions are sensed by the HOG SAPK pathway, which orchestrates the cell adaptation program required to maximize cell survival upon stress. Although most of the HOG pathway components have been described, little was known about the dynamics of the response. The aim of this thesis was to analyze the dynamic behavior of the HOG pathway.
