This book was released on 2008 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: DNA methylation is a key event regulating gene expression. DNA methylation analysis plays a pivotal role in unlocking association of epigenetic events with cancer. However, simultaneous evaluation of the methylation status of multiple genes is still a technical challenge. Microarray is a promising approach for high-throughput analysis of the methylation status at numerous CpG sites within multiple genes of interest. In this dissertation study, we conducted a systematic study to examine the use of microarray methods for methylation analysis. First, a robust universal microarray was established with more flexible in design and content, and potential cost saving over commercial arrays. In order to produce high quality microarray data, we optimized the attachment chemistry for the modified oligonucleotides, searched for the good combination of fluorescent dyes, and hybridization conditions. To improve the specificity of the microarray, we conducted a study to experimentally search for a set of highly discriminative tag Sequences. Second, SBE-TAGs microarray was successfully adapted from the SNP detection for methylation analysis of multiple genes. SBE-TAGs microarray performed quite well in multiplex methylation analysis of cell lines if a standard calibration curve method was used. 10 CpG sites of 9 tumor suppressor genes (MGMT, GATA4, HLTF, SOCS1, p16, RASSF2, CHFR, TPEF, and Reprimo) were selected for this study. Third, a novel method called CHZMA (Competing-Hybridization- Zipcode-MicroArray) was developed for methylation analysis of tumor tissue samples, which is based on two steps of hybridization to achieve the specific detection of methylation on microarray. On the basis of analysis of seven genes (MGMT, GATA4, HLTF, SOCS1, RASSF2, ER, 3-OST-2), we found that the CHZMA assay can robustly detect methylation of multiple genes in the samples containing as low as 10% of methylated DNA. With the strict control group test and statistical analysis, CHZMA can be a good high-throughput method in place of MSP for methylation analysis of tumor tissue samples. These studies provide reliable and robust tools for methylation analysis, and could be used for cancer prognosis and diagnosis in the future.

This book was released on 2009 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epigenetic studies hold the promise of addressing some of the fundamental questions of human biology including development, cell differentiation, and the aetiological mechanisms of complex disease. Over the last years, several new large scale high throughput technologies have been developed to allow genome wide profiling of epigenetic signals such as DNA methylation and histone modifications. Two of such technologies were developed in our laboratory enabling a genome wide microarray based profiling of DNA methylation signatures and a high throughput method for the site specific interrogation of the density of methylated cytosine. Using these techniques, we identified a DNA methylation difference in the 3'UTR of the DLX1 gene with potentially functional implications to discordance in risk taking behavior in a single pair of MZ twins. We modeled a power analysis on the effect size of the detected difference and determined that approximately 6∼25 discordant twin pairs will be adequate to yield 80% power across the entire 12 K CpG island microarray platform using our epigenomic microarray profiling technique. We performed a DNA methylome analysis of MZ twins in white blood cells (WBC), buccal epithelial cells, and gut (rectum) biopsies (N=57 pairs in total) using 12K CpG island microarrays providing the basis for the first annotation of epigenetic metastability of ∼6,000 unique genomic regions in MZ twins. We performed a classical twin study on DNA methylation differences in WBC and buccal epithelial cells from 39 pairs of MZ twins to 40 pairs of DZ twins. DZ co-twins exhibited significantly higher epigenetic difference compared to the MZ co-twins in buccal cells (p=1.2x10-294). While such higher epigenetic discordance in DZ twins can result from DNA sequence differences, our in silico SNP analyses and comparison of methylomes in inbred vs. outbred mice favour the hypothesis that this is due to epigenomic differences in the zygotes. This study suggests that molecular mechanisms of heritability may not be limited to DNA sequence differences.

Download or read book Evolution of Translational Omics written by Institute of Medicine and published by National Academies Press. This book was released on 2012-09-13 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technologies collectively called omics enable simultaneous measurement of an enormous number of biomolecules; for example, genomics investigates thousands of DNA sequences, and proteomics examines large numbers of proteins. Scientists are using these technologies to develop innovative tests to detect disease and to predict a patient's likelihood of responding to specific drugs. Following a recent case involving premature use of omics-based tests in cancer clinical trials at Duke University, the NCI requested that the IOM establish a committee to recommend ways to strengthen omics-based test development and evaluation. This report identifies best practices to enhance development, evaluation, and translation of omics-based tests while simultaneously reinforcing steps to ensure that these tests are appropriately assessed for scientific validity before they are used to guide patient treatment in clinical trials.

Download or read book Handbook of Nutrition Diet and Epigenetics written by Vinood B. Patel and published by Springer. This book was released on 2019-02-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multivolume reference work addresses the fact that the well being of humankind is predicated not only on individuals receiving adequate nutrition but also on their genetic makeup. The work includes more than 100 chapters organized in the following major sections: Introduction and Overview; Epigenetics of Organs and Diseases in Relation to Diet and Nutrition; Detailed Processes in Epigenetics of Diet and Nutrition; Modulating Epigenetics with Diet and Nutrition; and Practical Techniques. While it is well known that genes may encode proteins responsible for structural and dynamic components, there is an increasing body of evidence to suggest that nutrition itself may alter the way in which genes are expressed via the process of epigenetics. This is where chemically imposed alteration in the DNA sequence occurs or where the functional expression of DNA is modulated. This may include changes in DNA methylation, non-coding RNA, chromatin, histone acetylation or methylation, and genomic imprinting. Knowledge regarding the number of dietary components that impact on epigenetic processes is increasing almost daily. Marshalling all the information on the complex relationships between diet, nutrition, and epigenetic processes is somewhat difficult due to the wide myriad of material. It is for this reason that the present work has been compiled.

Download or read book Epigenetics Protocols written by Trygve O. Tollefsbol and published by Humana Press. This book was released on 2004-07-23 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of epigenetics has grown exponentially in the past decade, and a steady flow of exciting discoveries in this area has served to move it to the forefront of molecular biology. Although epigenetics may previously have been considered a peripheral science, recent advances have shown considerable progress in unraveling the many mysteries of nontraditional genetic processes. Given the fast pace of epigenetic discoveries and the groundbreaking nature of these developments, a thorough treatment of the methods in the area seems timely and appropriate and is the goal of Epigenetics Protocols. The scope of epigenetics is vast, and an exhaustive analysis of all of the techniques employed by investigators would be unrealistic. However, this TM volume of Methods in Molecular Biology covers three main areas that should be of greatest interest to epigenetics investigators: (1) techniques related to analysis of chromatin remodeling, such as histone acetylation and methylation; (2) methods in newly developed and especially promising areas of epigenetics such as telomere position effects, quantitative epigenetics, and ADP ribosylation; and (3) an updated analysis of techniques involving DNA methylation and its role in the modification, as well as the maintenance, of chromatin structure.
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.
