Download or read book Mathematical Modeling of NF B and p53 Signaling in the DNA Damage Response written by Fabian Konrath and published by Logos Verlag Berlin GmbH. This book was released on 2020-07-24 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cells are permanently challenged by DNA damage which can be induced by environmental factors such as UV irradiation or intracellular factors like reactive oxygen species. As damaged DNA can lead to malignant transformations, a complex signaling network termed DNA damage response is activated upon detection of DNA lesions and allows to maintain genomic integrity. The two transcription factors NF-κB and p53 regulate cell fate decisions upon genotoxic stress and therefore play crucial roles in the DNA damage response. To investigate the regulation of NF-κB activity, a mathematical model of coupled ordinary differential equations was developed and analyzed. The model describes DNA damage-induced activation of NF-$&appa;B and quantitatively reproduces multiple experimental data sets. Analyzing the time-resolved regulation of NF-κB revealed regulatory mechanisms of DNA damage-dependent NF-κB signaling and allowed the evaluation of drug targets inhibiting NF-κB activity. Further, the interplay of NF-κB and p53 signaling was investigated by developing a mathematical modeling framework to systematically identify interfaces between the NF-κB and p53 network. NF-κB signaling was perturbed and the resulting changes in single cell dynamics of p53 upon genotoxic stress were captured. By fitting a pool of subpopulation-specific ordinary differential equation models to the single cell data, one of the first quantitative p53 models reproducing the heterogeneous dynamics of p53 was developed. Based on the observed changes in p53 dynamics, the results of the modeling framework indicate that NF-κB signaling interferes with the activation and degradation of p53 as well as the degradation of its inhibitor Mdm2. Taken together, the results in this work give new insights into the regulation of genotoxic NF-κB and p53 signaling and highlight the complexity of their crosstalk.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
Download or read book The Regulation of Cellular Systems written by Reinhart Heinrich and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is no doubt that nowadays, biology benefits greatly from mathematics. In particular, cellular biology is, besides population dynamics, a field where tech niques of mathematical modeling are widely used. This is reflected by the large number of journal articles and congress proceedings published every year on the dynamics of complex cellular processes. This applies, among others, to metabolic control analysis, where the number of articles on theoretical fundamentals and experimental applications has increased for about 15 years. Surprisingly, mono graphs and textbooks dealing with the modeling of metabolic systems are still exceptionally rare. We think that now time is ripe to fill this gap. This monograph covers various aspects of the mathematical description of enzymatic systems, such as stoichiometric analysis, enzyme kinetics, dynamical simulation, metabolic control analysis, and evolutionary optimization. We believe that, at present, these are the main approaches by which metabolic systems can be analyzed in mathematical terms. Although stoichiometric analysis and enzyme kinetics are classical fields tracing back to the beginning of our century, there are intriguing recent developments such as detection of elementary biochemical syn thesis routes and rate laws for the situation of metabolic channeling, which we have considered worth being included. Evolutionary optimization of metabolic systems is a rather new field with promising prospects. Its goal is to elucidate the structure and functions of these systems from an evolutionary viewpoint.

Download or read book The DNA Damage Response Implications on Cancer Formation and Treatment written by Kum Kum Khanna and published by Springer Science & Business Media. This book was released on 2009-09-18 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ?eld of cellular responses to DNA damage has attained widespread recognition and interest in recent years commensurate with its fundamental role in the ma- tenance of genomic stability. These responses, which are essential to preventing cellular death or malignant transformation, are organized into a sophisticated s- tem designated the “DNA damage response”. This system operates in all living organisms to maintain genomic stability in the face of constant attacks on the DNA from a variety of endogenous by-products of normal metabolism, as well as exogenous agents such as radiation and toxic chemicals in the environment. The response repairs DNA damage via an intricate cellular signal transduction network that coordinates with various processes such as regulation of DNA replication, tr- scriptional responses, and temporary cell cycle arrest to allow the repair to take place. Defects in this system result in severe genetic disorders involving tissue degeneration, sensitivity to speci?c damaging agents, immunode?ciency, genomic instability, cancer predisposition and premature aging. The ?nding that many of the crucial players involved in DNA damage response are structurally and functionally conserved in different species spurred discoveries of new players through similar analyses in yeast and mammals. We now understand the chain of events that leads to instantaneous activation of the massive cellular responses to DNA lesions. This book summarizes several new concepts in this rapidly evolving ?eld, and the advances in our understanding of the complex network of processes that respond to DNA damage.

Download or read book The Circadian Clock written by Urs Albrecht and published by Springer Science & Business Media. This book was released on 2010-01-23 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the invitation to edit this volume, I wanted to take the opportunity to assemble reviews on different aspects of circadian clocks and rhythms. Although most c- tributions in this volume focus on mammalian circadian clocks, the historical int- duction and comparative clocks section illustrate the importance of various other organisms in deciphering the mechanisms and principles of circadian biology. Circadian rhythms have been studied for centuries, but only recently, a mole- lar understanding of this process has emerged. This has taken research on circadian clocks from mystic phenomenology to a mechanistic level; chains of molecular events can describe phenomena with remarkable accuracy. Nevertheless, current models of the functioning of circadian clocks are still rudimentary. This is not due to the faultiness of discovered mechanisms, but due to the lack of undiscovered processes involved in contributing to circadian rhythmicity. We know for example, that the general circadian mechanism is not regulated equally in all tissues of m- mals. Hence, a lot still needs to be discovered to get a full understanding of cir- dian rhythms at the systems level. In this respect, technology has advanced at high speed in the last years and provided us with data illustrating the sheer complexity of regulation of physiological processes in organisms. To handle this information, computer aided integration of the results is of utmost importance in order to d- cover novel concepts that ultimately need to be tested experimentally.

Download or read book Stress Response and Immunity Links and Trade Offs written by Nadia Danilova and published by Bentham Science Publishers. This book was released on 2020-02-04 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: When environmental conditions deviate from the optimal range, stress ensues. Stress response is a set of reactions that allow the organism to adjust and survive adverse conditions. Stress can be physical, such as extreme temperature, radiation, injury, or psychological, caused by perceived danger or deprivation. Every living cell has biochemical mechanisms to cope with physical stress. These mechanisms show a degree of similarity among several types of living organisms. Stress Response and Immunity: Links and Trade Offs explores the functional and evolutionary connections between stress response and immunity. The book introduces the reader to the concept of stress and subsequently examines the connection between stress response and immunity at various evolutionary stages of living organisms - from bacteria to humans. The book also features chapters dedicated to the role of tumor suppressor genes and the immune system of the brain. The information presented in this reference demonstrates the profound effects of physical and psychological stress on human health. Readers with basic knowledge of molecular biology will learn about the interesting facets of stress responses and the evolutionary trade offs observed in different life forms.

Available in PDF, EPUB and Kindle. Book excerpt: 1 The Third International OPAALS Conference was an opportunity to explore and discuss digital ecosystem research issues as well as emerging and future trends in the field. The conference was organized by IPTI – Instituto de Pesquisas em Tecnologia e Inovação (www. ipti. org. br). IPTI is a member of the OPAALS Framework P- gramme 7 Network of Excellence, which is led by the London School of Economics and Political Science. OPAALS is a multi-disciplinary research network of excellence for developing the science and technology behind digital ecosystems. The conference was held within the scope of a broader EU–Brazil bilateral workshop hosted by IPTI in cooperation with the Brazilian government and the European Commission and designed to foster EU support of information and communications technologies (ICT) enablement and socio-economic development in Brazil. The event was held in the city of Aracajú, Sergipe, in the northeast of Brazil, during March 22–23, 2010. Aracajú is the capital of the state of Sergipe and is located on the coast, a tropical region with lush vegetation, rivers and mangroves and an e- nomic landscape dominated by fisheries, tourism and the challenges associated with fostering local economic development in the presence of low ICT penetration. Digital ecosystems (DEs) in some ways represent the next generation of ICT and Internet usage. Applicable to many contexts, they will perhaps have the greatest effect in enabling small and medium-sized enterprises (SMEs) to compete on the global stage.
