This book focuses on an “outside the box” notion by utilizing the powerful applications of next-generation sequencing (NGS) technologies in the interface of chemistry and biology. In personalized medicine, developing small molecules targeting a specific genomic sequence is an attractive goal. N-methylpyrrole (P)–N-methylimidazole (I) polyamides (PIPs) are a class of small molecule that can bind to the DNA minor groove. First, a cost-effective NGS (ion torrent platform)-based Bind-n-Seq was developed to identify the binding specificity of PIP conjugates in a randomized DNA library. Their biological influences rely primarily on selective DNA binding affinity, so it is important to analyze their genome-wide binding preferences. However, it is demanding to enrich specifically the small-molecule-bound DNA without chemical cross-linking or covalent binding in chromatinized genomes. Herein is described a method that was developed using high-throughput sequencing to map the differential binding sites and relative enriched regions of non-cross-linked SAHA-PIPs throughout the complex human genome. SAHA-PIPs binding motifs were identified and the genome-level mapping of SAHA-PIPs-enriched regions provided evidence for the differential activation of the gene network. A method using high-throughput sequencing to map the binding sites and relative enriched regions of alkylating PIP throughout the human genome was also developed. The genome-level mapping of alkylating the PIP-enriched region and the binding sites on the human genome identifies significant genomic targets of breast cancer. It is anticipated that this pioneering low-cost, high through-put investigation at the sequence-specific level will be helpful in understanding the binding specificity of various DNA-binding small molecules, which in turn will be beneficial for the development of small-molecule-based drugs targeting a genome-level sequence.

Synthetic Biology is a scientific discipline that has the potential to revolutionize the way we understand and manipulate life. Combining knowledge from biology, genetics, engineering and computing, Synthetic Biology opens up new possibilities for creating personalized biological systems, with applications ranging from regenerative medicine to the production of biofuels. In this book, we will explore the principles, techniques, and applications of synthetic biology, with the aim of providing a comprehensive and up-to-date overview of this ever-evolving field. Throughout the chapters, we will delve into the molecular foundations of Synthetic Biology, exploring the biological components and processes involved in building synthetic biological systems. We will present several applications of Synthetic Biology in different sectors, highlighting its role in the pharmaceutical industry, in the production of biofuels, in the development of personalized vaccines and in regenerative medicine. We will see how the manipulation of synthetic stem cells can revolutionize the area of tissue regeneration and how metabolic engineering allows us to design microorganisms capable of producing valuable compounds. Bioinformatics plays a crucial role in Synthetic Biology, and we will dedicate a chapter to exploring how the analysis of genomic data and the use of bioinformatics algorithms contribute to the advancement of this discipline. In addition, we will cover topics such as genome editing using CRISPR technology, synthetic protein engineering, and directed evolution in the laboratory. With the advancement of technology, it has become possible to manufacture living tissue in the laboratory, and we will discuss biofabrication and 3D printing of living tissue, as well as the use of microfluidics in the manipulation and analysis of synthetic biological systems on a microscopic scale. We will also address ethical and biosafety issues related to Synthetic Biology, recognizing the importance of a responsible approach in all its applications. This book is intended for students, researchers, and practitioners interested in exploring the frontiers of synthetic biology. We hope it will be an inspiring source of knowledge, awakening the curiosity and innovative spirit of all readers. We invite you to embark on this exciting journey through Synthetic Biology, in search of a deeper understanding of life and its transformative possibilities.

Whether or not the United States has safe and effective medical countermeasures-such as vaccines, drugs, and diagnostic tools-available for use during a disaster can mean the difference between life and death for many Americans. The Food and Drug Administration (FDA) and the scientific community at large could benefit from improved scientific tools and analytic techniques to undertake the complex scientific evaluation and decision making needed to make essential medical countermeasures available. At the request of FDA, the Institute of Medicine (IOM) held a workshop to examine methods to improve the development, evaluation, approval, and regulation of medical countermeasures. During public health emergencies such as influenza or chemical, biological, radiological/nuclear (CBRN) attacks, safe and effective vaccines, treatments, and other medical countermeasures are essential to protecting national security and the well being of the public. Advancing Regulatory Science for Medical Countermeasure Development examines current medical countermeasures, and investigates the future of research and development in this area. Convened on March 29-30, 2011, this workshop identified regulatory science tools and methods that are available or under development, as well as major gaps in currently available regulatory science tools. Advancing Regulatory Science for Medical Countermeasure Development is a valuable resource for federal agencies including the Food and Drug Administration (FDA), the Department of Health and Human Services (HHS), the Department of Defense (DoD), as well as health professionals, and public and private health organizations.
