Circulating cell-free DNA is poised to transform cancer diagnosis and care; however, it carries technical challenges such as low abundance, fragmentation and sensitivity to biospecimen handling. Development of clinically useful assays hinges on understanding the unique technical aspects of working with cell-free DNA as a substrate. This book provides an in-depth summary of the technical issues impacting cell-free DNA purification from blood plasma and analysis in a cancer context, including design of PCR assays, sequencing library preparation and methylation analysis. Emerging fields such as extracellular vesicles and blood nucleases are also covered, as well as basic biology and considerations pertinent to biobanking.

One of the world's leading experts on genetics unravels one of the most important breakthroughs in modern science and medicine. IIf our genes are, to a great extent, our destiny, then what would happen if mankind could engineer and alter the very essence of our DNA coding? Millions might be spared the devastating effects of hereditary disease or the challenges of disability, whether it was the pain of sickle-cell anemia to the ravages of Huntington's disease. But this power to “play God” also raises major ethical questions and poses threats for potential misuse. For decades, these questions have lived exclusively in the realm of science fiction, but as Kevin Davies powerfully reveals in his new book, this is all about to change. Engrossing and page-turning, Editing Humanity takes readers inside the fascinating world of a new gene editing technology called CRISPR, a high-powered genetic toolkit that enables scientists to not only engineer but to edit the DNA of any organism down to the individual building blocks of the genetic code. Davies introduces readers to arguably the most profound scientific breakthrough of our time. He tracks the scientists on the front lines of its research to the patients whose powerful stories bring the narrative movingly to human scale. Though the birth of the “CRISPR babies” in China made international news, there is much more to the story of CRISPR than headlines seemingly ripped from science fiction. In Editing Humanity, Davies sheds light on the implications that this new technology can have on our everyday lives and in the lives of generations to come.

This is the first book portraying to a wide readership many fields of DNA in the world of materials altogether in a single volume. The book provides underlying concepts and state-of-art developments in the emerging fields of DNA electronics, structural DNA nanotechnology, DNA computing and DNA data storage, DNA machines and nanorobots. Future possibilities of innovative DNA-based technologies, such as DNA cryptography, DNA identity tags, DNA nanostructures in biosensing and nanomedicine, as well as DNA-based nanoelectronics are all covered, too. This book is valuable for university students studying engineering and technology; biotech, nanotech, and medical device R&D managers, practitioners and investors; and IP analysts who would like to extend their background in advanced DNA technologies. It is nicely illustrated, which makes it very readable, and it conveys science and principles in a lively language to appeal to a broad audience, from professionals and academics to students and lay readers. Advance Praise for DNA Beyond Genes:“Most students of DNA, and lay readers as well, are interested in the absolutely essential role it plays in biology. However, the properties which make DNA the carrier of genetic information also make it an extraordinary material that can be used as the backbone for a wide variety of nanoengineering applications – these range from information storage and computation to molecular machines and devices to artfully designed logos and symbols. The perfect self-recognition of DNA sequences makes it an ideal building block to synthesize more and more elaborate constructions and imaginative scientists have probably only just scratched the surface of what can eventually be created. Here for the first time in this wonderful book Vadim Demidov explores the full range of the non-biological applications of DNA.”Charles R.

Storing Digital Binary Data into Cellular DNA demonstrates how current digital information storage systems have short longevity and limited capacity, also pointing out that their production and consumption of data exceeds supply. Author Rocky Termanini explains the DNA system and how it encodes vast amounts of data, then presents information on the emergence of DNA as a storage technology for the ever-growing stream of data being produced and consumed. The book will be of interest to a range of readers looking to understand this game-changing technology, including researchers in computer science, biomedical engineers, geneticists, physicians, clinicians, law enforcement and cybersecurity experts. Presents a comprehensive reference on the fascinating and emerging technology of DNA storage Helps readers understand key concepts on how DNA works as an information storage system Provides readers with key information on the technologies used to work with DNA data encoding, such as CRISPR Covers emerging areas of application and ethical concern, such as Smart Cities, cybercrime and cyberwarfare Includes coverage of synthesizing DNA-encoded data, sequencing DNA-encoded data, and fusing DNA with Digital Immunity Ecosystems (DIE)

In this book, the molecular recognition of DNA using small molecules is discussed, with a study of the photochemistry of BrU-labeled DNA. The purposes of the study were to develop small molecules for regenerative medicine, to develop a method to detect the recognition site of small molecules, and to detect the most important biological phenomena using the photochemistry of BrU-labeled DNA. The study began with the design and development of small molecules that can induce pluripotency genes. To deal with the important issue of cell permeability of the original compound, a new analogue of the original with improved gene expression was designed and synthesized. Using the photochemistry of BrU-labeled DNA, crucial biological phenomena such as cooperativity between transcription factors were detected. For the first time, the cooperativity was examined by excess electron transfer assay. DNA was also studied very carefully in order to understandthe mechanism of the double-strand break in the UVA micro-irradiation technique. The mechanism of the double strand remained untouched. Nevertheless, the double-strand break mechanism was clearly demonstrated by Hoechst dye, as shown in this book.

The aim of molecular diagnostics is preferentially to detect a developing disease before any symptoms appear. There has been a significant increase, fueled by technologies from the human genome project, in the availability of nucleic acid sequence information for all living organisms including bacteria and viruses. When combined with a different type of instrumentation applied, the resulting diagnostics is specific and sensitive. Nucleic acid-based medical diagnosis detects specific DNAs or RNAs from the infecting organism or virus and a specific gene or the expression of a gene associated with a disease. Nucleic acid approaches also stimulate a basic science by opening lines of inquiry that will lead to greater understanding of the molecules at the center of life. One can follow Richard Feynman's famous statement “What I cannot create, I do not understand.”

For decades after the identification of the structure of DNA, scientists focused only on genes, the regions of the genome that contain codes for the production of proteins. Other regions that make up 98 percent of the human genome were dismissed as'junk,'sequences that serve no purpose. But researchers have recently discovered variations and modulations in this junk DNA that are involved with a number of intractable diseases. Our increasing knowledge of junk DNA has led to innovative research and treatment approaches that may finally ameliorate some of these conditions.Junk DNA can play vital and unanticipated roles in the control of gene expression, from fine-tuning individual genes to switching off entire chromosomes. These functions have forced scientists to revisit the very meaning of the word'gene'and have engendered a spirited scientific battle over whether or not this genomic'nonsense'is the source of human biological complexity. Drawing on her experience with leading scientific investigators in Europe and North America, Nessa Carey provides a clear and compelling introduction to junk DNA and its critical involvement in phenomena as diverse as genetic diseases, viral infections, sex determination in mammals, and evolution. We are only now unlocking the secrets of junk DNA, and Nessa Carey's book is an essential resource for navigating the history and controversies of this fast-growing, hotly disputed field.
