👩‍🔬Intro to Biotechnology Unit 13 – Bioethics and Regulations in Biotech

Key Concepts and Principles

• Bioethics examines ethical issues arising from advances in biology, medicine, and biotechnology
• Focuses on the moral and societal implications of research, development, and applications in these fields
• Considers principles such as autonomy, beneficence, non-maleficence, and justice
  • Autonomy respects an individual's right to make informed decisions about their own body and health
  • Beneficence promotes actions that benefit others and minimize harm
  • Non-maleficence avoids actions that cause harm or injury to others
  • Justice ensures fair distribution of benefits and burdens across society
• Balances potential benefits of biotechnology against risks and unintended consequences
• Addresses issues related to human dignity, privacy, informed consent, and equitable access to technologies
• Promotes responsible conduct of research and innovation in biotechnology
• Engages diverse stakeholders, including scientists, policymakers, healthcare professionals, and the public, in ethical deliberations

Historical Context and Milestones

• Bioethics emerged as a distinct field in the 1960s and 1970s, coinciding with advances in medical technologies and research
• Key events and developments that shaped the field include:
  • The Nuremberg Code (1947) established principles for ethical human subjects research following Nazi atrocities during World War II
  • The Belmont Report (1979) outlined ethical principles and guidelines for protecting human subjects in biomedical research
  • The Human Genome Project (1990-2003) raised ethical questions about genetic information, privacy, and discrimination
• Early bioethical debates focused on issues such as organ transplantation, end-of-life care, and reproductive technologies
• The emergence of recombinant DNA technology in the 1970s sparked concerns about the safety and ethical implications of genetic engineering
• High-profile cases, such as the Tuskegee Syphilis Study and the case of Henrietta Lacks, highlighted issues of informed consent and exploitation in biomedical research
• The development of stem cell research and cloning technologies in the 1990s and 2000s generated intense ethical debates about the moral status of embryos and the permissibility of these practices

Ethical Frameworks in Biotechnology

• Utilitarianism evaluates the morality of actions based on their consequences, aiming to maximize overall utility or well-being for the greatest number of people
• Deontology emphasizes the inherent rightness or wrongness of actions based on moral rules or duties, such as respect for autonomy and the prohibition against using people merely as means to an end
• Virtue ethics focuses on the moral character of individuals and the cultivation of virtues such as compassion, integrity, and wisdom in decision-making
• Principlism, a common approach in bioethics, applies the four principles of autonomy, beneficence, non-maleficence, and justice to analyze and resolve ethical dilemmas
• Casuistry relies on case-based reasoning, drawing on paradigmatic cases and analogies to guide decision-making in novel situations
• Feminist bioethics attends to issues of gender, power, and marginalization in the context of biotechnology and healthcare
• Global bioethics considers the ethical implications of biotechnology in a global context, addressing issues of cultural diversity, social justice, and international governance

Major Bioethical Issues

• Genetic engineering and modification, including the use of CRISPR-Cas9 and other gene-editing technologies, raise questions about the permissibility of altering the human genome and the potential for unintended consequences
• Stem cell research, particularly the use of embryonic stem cells, generates debates about the moral status of embryos and the ethics of destroying them for research purposes
• Reproductive technologies, such as in vitro fertilization (IVF) and preimplantation genetic diagnosis (PGD), raise concerns about the selection and manipulation of embryos and the potential for genetic discrimination
• Cloning, both therapeutic and reproductive, sparks discussions about the ethics of creating genetically identical individuals and the implications for human identity and uniqueness
• Genetically modified organisms (GMOs) in agriculture and food production generate debates about the safety, environmental impact, and socioeconomic consequences of these technologies
• Biobanking and the collection, storage, and use of human biological materials for research purposes raise issues of informed consent, privacy, and ownership of genetic information
• Neuroethics examines the ethical implications of neuroscience research and interventions, such as brain-computer interfaces, cognitive enhancement, and the use of neurotechnologies for non-medical purposes

Regulatory Bodies and Guidelines

• National and international regulatory bodies play a crucial role in overseeing and governing biotechnology research and applications
• In the United States, key regulatory agencies include:
  • The Food and Drug Administration (FDA), which regulates the safety and efficacy of drugs, medical devices, and biological products
  • The National Institutes of Health (NIH), which provides guidelines for federally funded biomedical research, including stem cell research
  • The Environmental Protection Agency (EPA), which regulates the use and release of genetically modified organisms in the environment
• International organizations, such as the World Health Organization (WHO) and the United Nations Educational, Scientific, and Cultural Organization (UNESCO), develop global guidelines and declarations on bioethics and human rights
• Professional societies, such as the American Society for Bioethics and Humanities (ASBH) and the International Association of Bioethics (IAB), provide guidance and promote ethical standards in biotechnology research and practice
• Institutional Review Boards (IRBs) and Ethics Committees review and oversee research involving human subjects to ensure compliance with ethical guidelines and protect participant rights and welfare

Case Studies and Controversies

• The case of Jesse Gelsinger, who died during a gene therapy clinical trial in 1999, highlighted the risks and ethical challenges of early-stage gene therapy research
• The controversy surrounding the creation of the first genetically modified human embryos in China in 2018 sparked global debates about the ethics and governance of human germline editing
• The Havasupai Tribe's lawsuit against Arizona State University in 2004 for misuse of their genetic samples without informed consent raised issues of cultural sensitivity, trust, and exploitation in genetic research with indigenous communities
• The debate over the patenting of the BRCA1 and BRCA2 genes by Myriad Genetics in the 1990s and 2000s raised questions about the ownership and accessibility of genetic information and the implications for patient care and research
• The development of "three-parent babies" through mitochondrial replacement therapy in the UK in 2015 generated discussions about the ethics of modifying the human germline and the potential for creating children with three genetic parents
• The case of He Jiankui, a Chinese scientist who claimed to have created the world's first gene-edited babies in 2018, highlighted the need for international governance and oversight of human germline editing research

Current Challenges and Future Directions

• Ensuring equitable access to biotechnologies and their benefits, particularly for marginalized and underserved populations
• Addressing the potential for genetic discrimination and the misuse of genetic information in employment, insurance, and other contexts
• Navigating the ethical and social implications of emerging technologies, such as synthetic biology, gene drives, and human-animal chimeras
