This book was released on 2011 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Replication errors that escape DNA polymerase proof-reading activity are efficientl y recognized and repaired by conserved DNA mismatch repair factors. The overall result is a drastic reduction in deletion mutations. The mechanistic details of how mismatch repair proteins execute mismatch removal have not been elucidated. The aim of my thesis is to better understand how mismatch repair factors interact with DNA in order to identify mismatch sites. My work reveals that the mismatch repair complex, MLH1-PMS1, has unique DNA diffusion characteristics facilitated by structural features of the two subunits. Through bulk assays and total internal reflectance fluorescence microscopy (TIRFM), I found that MLH1PMS1 could independently bind DNA and rapidly diffuse using the thermal energy of the system. Furthermore, MLH1-PMS1 was shown to be the first passively diffusing protein that could bypass stationary nucleosomes. In contrast, the DNA diffusion activity of the mismatch recognition complex MSH2-MSH6 was blocked by nucleosomes. The timing and nature of mismatch repair is linked with replication and is thus proposed that the differences seen for the two complexes have important implications for repair in the context of the chromatin state directly at the replication fork. Each subunit of the MLH1-PMS1 complex is composed of two defined globular domains connected by an unstructured linker arm. The linker arms of the complex are proposed to facilitate topological DNA binding and diffusion along DNA in a hopping/stepping mechanism. I found that TEV protease cleavage within the linker arms of MLH1-PMS1 disrupted DNA binding and mismatch repair in vitro and in vivo. Using a genetic mismatch repair assay I found that shortening of the linker arms in MLH1 had a drastic effect on function whereas similar changes in PMS1 had little or no effect. Purified truncated complexes were able to interact with DNA and form ternary complexes with MSH2-MSH6 at a mismatch. Future studies should focus on the diffusion characteristic for these complexes. Together, my work has important implications for understanding how mismatch repair proteins can rapidly identify their targets in a chromatin landscape.

Download or read book DNA Damage and Repair written by A. Castellani and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: The First International Congress on DNA Damage and Repair was held in Rome, Italy, July 12-17, 1987. It was organized by the Italian Com mission for Nuclear Alternative Energy Sources. The subject of DNA damage and repair involves almost all the fields ofbidogical sciences. Some of the more prominent ones include carcino genesis, photobiology, radiation biology, aging, enzymology, genetics, and molecular biology. These individual fields have their own interna tional meetings and although the meetings often have sessions devoted to DNA repair, they do not bring together a wide diversity of international workers in the field to exchange ideas. The purpose of the Congress was to facilitate such an exchange among scientists representing many fields of endeavor and many countries. The 37 manuscripts in this volume, presented by the invited spea kers during the four and half days of the Congress, encompass the field of DNA damage and repair. They cover biological systems ranging from mo lecules to humans and deal with damages and repair after treatment of cells with various types of radiations, chemicals, and exogenous and en dogenous oxidative damages. The Congress and its Proceedings are dedicated to two international leaders in the field of DNA damage and repair, Alexander Hollaender of the United States and Adriano Buzzati Traverso of Italy. Hollaender, who died in December 1986, was one of the first investigators to recognize the damage to DNA was important in cell killing and mutagenesis. His early work indicated that cells could recover from radiation injury.

Download or read book Dynamics of Cancer written by Steven A. Frank and published by Princeton University Press. This book was released on 2018-06-05 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: The onset of cancer presents one of the most fundamental problems in modern biology. In Dynamics of Cancer, Steven Frank produces the first comprehensive analysis of how particular genetic and environmental causes influence the age of onset. The book provides a unique conceptual and historical framework for understanding the causes of cancer and other diseases that increase with age. Using a novel quantitative framework of reliability and multistage breakdown, Frank unifies molecular, demographic, and evolutionary levels of analysis. He interprets a wide variety of observations on the age of cancer onset, the genetic and environmental causes of disease, and the organization of tissues with regard to stem cell biology and somatic mutation. Frank uses new quantitative methods to tackle some of the classic problems in cancer biology and aging: how the rate of increase in the incidence of lung cancer declines after individuals quit smoking, the distinction between the dosage of a chemical carcinogen and the time of exposure, and the role of inherited genetic variation in familial patterns of cancer. This is the only book that presents a full analysis of the age of cancer onset. It is a superb teaching tool and a rich source of ideas for new and experienced researchers. For cancer biologists, population geneticists, evolutionary biologists, and demographers interested in aging, this book provides new insight into disease progression, the inheritance of predisposition to disease, and the evolutionary processes that have shaped organismal design.
Download or read book DNA Replication Recombination and Repair written by Fumio Hanaoka and published by Springer. This book was released on 2016-01-22 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive review of the detailed molecular mechanisms of and functional crosstalk among the replication, recombination, and repair of DNA (collectively called the "3Rs") and the related processes, with special consciousness of their biological and clinical consequences. The 3Rs are fundamental molecular mechanisms for organisms to maintain and sometimes intentionally alter genetic information. DNA replication, recombination, and repair, individually, have been important subjects of molecular biology since its emergence, but we have recently become aware that the 3Rs are actually much more intimately related to one another than we used to realize. Furthermore, the 3R research fields have been growing even more interdisciplinary, with better understanding of molecular mechanisms underlying other important processes, such as chromosome structures and functions, cell cycle and checkpoints, transcriptional and epigenetic regulation, and so on. This book comprises 7 parts and 21 chapters: Part 1 (Chapters 1–3), DNA Replication; Part 2 (Chapters 4–6), DNA Recombination; Part 3 (Chapters 7–9), DNA Repair; Part 4 (Chapters 10–13), Genome Instability and Mutagenesis; Part 5 (Chapters 14–15), Chromosome Dynamics and Functions; Part 6 (Chapters 16–18), Cell Cycle and Checkpoints; Part 7 (Chapters 19–21), Interplay with Transcription and Epigenetic Regulation. This volume should attract the great interest of graduate students, postdoctoral fellows, and senior scientists in broad research fields of basic molecular biology, not only the core 3Rs, but also the various related fields (chromosome, cell cycle, transcription, epigenetics, and similar areas). Additionally, researchers in neurological sciences, developmental biology, immunology, evolutionary biology, and many other fields will find this book valuable.
