Stochastic modelling of the MAPK signalling pathway

2006-06-01
The MAPK (mitogen-activated protein kinase) or its synonymous ERK (extracellular signal regulated kinase) pathway whose components are Ras, Raf, and MEK proteins with many biochemical links, is one of the major signalling systems involved in cellular growth control of eukaryotes including cell proliferation, transformation, differentiation, and apoptosis. Because of its diverse functionality, it is also activated in a variety of hormone activation and many illnesses, which have multi-complex gene structure like cancer and heart diseases. In this study we describe the MAPK/ERK pathway via (quasi) biochemical reactions and then implement the pathway by a stochastic Markov process. We use two techniques, Gillespie algorithm and diffusion approximation, to simulate reactions and we compare their results. A novelty of our approach is to use multiple parametrizations in order to deal with molecules for which localization in the cell is an intricate part of the dynamic process.

Bayesian inference for the MAPK/ERK pathway by considering the dependency of the kinetic parameters
Purutçuoğlu Gazi, Vilda (Institute of Mathematical Statistics, 2008-01-01)
The MAPK/ERK pathway is one of the major signal transduction systems which regulates the cellular growth control of all eukaryotes like the cell proliferation and the apoptosis. Because of its importance in cellular lifecycle, it has been studied intensively, resulting in a number of qualitative descriptions of this regulatory mechanism. In this study we describe the MAPK/ERK pathway as an explicit set of reactions by combining different sources. Our reaction set takes into account the localization and diff...
Automatic detection of mitochondria from electron microscope tomography images: a curve fitting approach
Tasel, Serdar F.; HASSANPOUR, REZA; Mumcuoğlu, Ünal Erkan; Perkins, Guy; Martone, Maryann (2014-02-18)
Mitochondria are sub-cellular components which are mainly responsible for synthesis of adenosine tri-phosphate (ATP) and involved in the regulation of several cellular activities such as apoptosis. The relation between some common diseases of aging and morphological structure of mitochondria is gaining strength by an increasing number of studies. Electron microscope tomography (EMT) provides high-resolution images of the 3D structure and internal arrangement of mitochondria. Studies that aim to reveal the c...
Inference of Gene Regulatory Networks Via Multiple Data Sources and a Recommendation Method
Ozsoy, Makbule Gulcin; Polat, Faruk; Alhajj, Reda (2015-11-12)
Gene regulatory networks (GRNs) are composed of biological components, including genes, proteins and metabolites, and their interactions. In general, computational methods are used to infer the connections among these components. However, computational methods should take into account the general features of the GRNs, which are sparseness, scale-free topology, modularity and structure of the inferred networks. In this work, observing the common aspects between recommendation systems and GRNs, we decided to ...
Simultaneous Reconstruction of Multiple Signaling Pathways via the Prize-Collecting Steiner Forest Problem
Tunçbağ, Nurcan; PAGNANI, Andrea; Huang, Shao-Shan Carol; CHAYES, Jennifer; BORGS, Christian; Zecchina, Riccardo; FRAENKEL, Ernest (2013-02-01)
Signaling and regulatory networks are essential for cells to control processes such as growth, differentiation, and response to stimuli. Although many "omic'' data sources are available to probe signaling pathways, these data are typically sparse and noisy. Thus, it has been difficult to use these data to discover the cause of the diseases and to propose new therapeutic strategies. We overcome these problems and use "omic'' data to reconstruct simultaneously multiple pathways that are altered in a particula...
