Advancing Development of Synthetic Gene Regulators available in PDF, EPUB and Kindle. 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.

Many potential applications of synthetic and systems biology are relevant to the challenges associated with the detection, surveillance, and responses to emerging and re-emerging infectious diseases. On March 14 and 15, 2011, the Institute of Medicine's (IOM's) Forum on Microbial Threats convened a public workshop in Washington, DC, to explore the current state of the science of synthetic biology, including its dependency on systems biology; discussed the different approaches that scientists are taking to engineer, or reengineer, biological systems; and discussed how the tools and approaches of synthetic and systems biology were being applied to mitigate the risks associated with emerging infectious diseases. The Science and Applications of Synthetic and Systems Biology is organized into sections as a topic-by-topic distillation of the presentations and discussions that took place at the workshop. Its purpose is to present information from relevant experience, to delineate a range of pivotal issues and their respective challenges, and to offer differing perspectives on the topic as discussed and described by the workshop participants. This report also includes a collection of individually authored papers and commentary.

The main goal of synthetic biology is to harness the power of biological genetic expression in order to perform various tasks, which could often have an impact on many aspects of our lives ranging from healthcare, pharmaceutical, to renewable energy and environments. These tasks are often carried out through synthetic genetic circuits composed of genetic parts like promoters, RBS, terminators, and inducible gene regulators. Numerous studies have expanded the toolbox for synthetic circuitry and established the guideline of circuitry assembly in the past decade. As the field advances, regulatory sRNA is emerging as a powerful tool in synthetic biology. These regulatory sRNAs are versatile and designable, more importantly, they offer a fast dynamic in genetic circuitry due to the fast production rates and degradation rates of RNA molecules. However, little work has been done to create a theoretical foundation for RNA circuit design. With the ultimate goal of gaining full control of RNA circuitry dynamics, this work focuses on building the theoretical foundation to understand and guide the design of RNA synthetic circuitry. A prerequisite to building such a foundation is to create a modeling framework that accurately describes the dynamics of RNA circuits. In the first part of this work, we build an effective model composed of ordinary differential equations to describe transcriptional RNA genetic circuitry and validate the model using a three-level cascade as a test case. We develop a sensitivity analysis based parameterization procedure that requires only a handful of simple experiments that can be performed in parallel using rapid cell-free transcription-translation (TX-TL) reactions. This part of the work establishes a fundamental method to predict circuit dynamics, which allow us to build more complex systems. Next, we expand the repertoire of synthetic gene networks built from these regulators by constructing a transcriptional negative autoregulation (NAR) network out of small RNAs (sRNAs). Using parameter sensitivity analysis, we design a simple set of experiments that allow us to accurately predict the NAR circuit dynamic in TX-TL. We also transfer the successful network design into Escherichia coli and show that our sRNA transcriptional network is functional in vivo. In the third part of this work, we investigate into an interesting observation where the transfer functions of inducible systems are altered by small transcriptional activating RNAs (STARs). We combine theory, computational model and experimental results to uncover the underlying causes of this phenomenon. Based on which, we establish the design principle of transfer function manipulation and dynamic range amplification induced by STARs. Together the work presented here establishes a theoretical foundation of RNA circuitry design. We anticipate that this foundation would support the development of new mathematical and computational models that provide insights and guidance for RNA circuitry design -which ultimately contributes to the advancement of synthetic circuitry engineering.

Biodefense in the Age of Synthetic Biology available in PDF, EPUB and Kindle. Scientific advances over the past several decades have accelerated the ability to engineer existing organisms and to potentially create novel ones not found in nature. Synthetic biology, which collectively refers to concepts, approaches, and tools that enable the modification or creation of biological organisms, is being pursued overwhelmingly for beneficial purposes ranging from reducing the burden of disease to improving agricultural yields to remediating pollution. Although the contributions synthetic biology can make in these and other areas hold great promise, it is also possible to imagine malicious uses that could threaten U.S. citizens and military personnel. Making informed decisions about how to address such concerns requires a realistic assessment of the capabilities that could be misused. Biodefense in the Age of Synthetic Biology explores and envisions potential misuses of synthetic biology. This report develops a framework to guide an assessment of the security concerns related to advances in synthetic biology, assesses the levels of concern warranted for such advances, and identifies options that could help mitigate those concerns.
