Use Of Knowledge

This chapter explores the fields of biotechnology and synthetic biology. The micro-scale of synthetic biology clearly indicates the use of knowledge drawn from biochemistry. But its philosophy is more closely aligned to the principles of engineering than those of pure science. The chapter then looks at some examples of synthetic biochemistry, and reflects on what this new field might herald. It studies the creation of synthetic organisms and genomes. The chapter also considers gene editing and the emergence of a powerful gene editing technique, known as CRISPR (from clustered, regularly interspaced, short palindromic repeats). Finally, it addresses ethical issues and the darker applications of these technologies.

Responsible Research

Synthetic biology is an emerging field at the interface between biology and engineering, which has generated many expectations for beneficial biomedical and biotechnological applications. At the same time, however, it has also raised concerns about risks or the aim of producing new forms of living organisms. Researchers from different disciplines as well as policymakers and the general public have expressed the need for a form of technology assessment that not only deals with technical aspects, but also includes societal and ethical issues. A recent and very influential model of technology assessment that tries to implement these aims is known as RRI (Responsible Research and Innovation). In this paper, we introduce this model and its historical precursor strategies. Based on the societal and ethical issues which are presented in the current literature, we discuss challenges and opportunities of applying the RRI model for the assessment of synthetic biology.

Given the speed of change in the development of new technologies mentioned in this book such as genome editing, optogenetics, stem cell organoids, and synthetic biology, it is hard to predict exactly how radically these technologies are likely to transform our lives in coming decades. What is clear is that as exciting as the new biotechnologies are in terms of their impact on medical research, medicine, and agriculture, they also raise a whole number of socio-political and ethical issues. These include concerns about whether monkeys engineered to have genetic similarities to humans might lead to a ‘Planet of the Apes’ scenario, and fears about ‘designer babies’ being produced in the future to have greater beauty, intelligence or sporting skill. Although one potentially positive new development is the rise of a ‘biohacker’ movement which seeks to make molecular biology more accessible to ordinary people, there are also fears that in the wrong hands genome editing might be used to create new types of biological weapons for terrorist organisations. While such fears should not be dismissed as just an overreaction, to some extent they rest on an underestimation of the complexity of the Iink between the human genome and looks, intelligence, and sporting ability, or of the difficulties involved in creating a deadly virus that is worse than naturally occurring ones. Ultimately, the best way to ensure that new technologies are used for human benefit, not harm, is to take part in an informed debate and use public lobbying to argue for them to be developed safely, ethically, and responsibly.

Design of clinical trials for germline gene editing stretches current accepted standards for human subjects research. Among the challenges involved is a set of issues concerning intergenerational monitoring—long-term follow-up study of subjects and their descendants. Because changes made at the germline would be heritable, germline gene editing could have adverse effects on individuals’ health that can be passed on to future generations. Determining whether germline gene editing is safe and effective for clinical use thus may require intergenerational monitoring. The aim of this paper is to identify and argue for the significance of a set of ethical issues raised by intergenerational monitoring in future clinical trials of germline gene editing. Though long-term, multigenerational follow-up study of this kind is not without precedent, intergenerational monitoring in this context raises unique ethical challenges, challenges that go beyond existing protocols and standards for human subjects research. These challenges will need to be addressed if clinical trials of germline gene editing are ever pursued.

Abstract:Gene editors such as CRISPR could be used to create stronger, faster, or more resilient nonhuman animals. This is of keen interest to people who breed, train, race, and profit off the millions of animals used in sport that contribute billions of dollars to legal and illegal economies across the globe. People have tried for millennia to perfect sport animals; CRISPR proposes to do in one generation what might have taken decades previously. Moreover, gene editing may facilitate enhancing animals’ capacities beyond their typical limits. This paper describes the state of animal use and engineering for sport, examines the moral status of animals, and analyzes current and future ethical issues at the intersection of animal use, gene editing, and sports. We argue that animal sport enthusiasts and animal welfarists alike should be concerned about the inevitable use of CRISPR in sport animals. Though in principle CRISPR could be used to improve sport animals’ well-being, we think it is unlikely in practice to do so.

CRISPR (clustered, regularly interspaced, short palindromic repeats)/Cas9 (CRISPR-associated protein 9) has become the tool of choice for generating gene knockouts across a variety of species. The ability for efficient gene editing in primary T cells not only represents a valuable research tool to study gene function but also holds great promise for T cell–based immunotherapies, such as next-generation chimeric antigen receptor (CAR) T cells. Previous attempts to apply CRIPSR/Cas9 for gene editing in primary T cells have resulted in highly variable knockout efficiency and required T cell receptor (TCR) stimulation, thus largely precluding the study of genes involved in T cell activation or differentiation. Here, we describe an optimized approach for Cas9/RNP transfection of primary mouse and human T cells without TCR stimulation that results in near complete loss of target gene expression at the population level, mitigating the need for selection. We believe that this method will greatly extend the feasibly of target gene discovery and validation in primary T cells and simplify the gene editing process for next-generation immunotherapies.
