Han Y, Fan LL, Xue Y. A sustainable balance between innovation and risk: How the "right to science" affects China's medical biotechnology regulatory policy. Comput Struct Biotechnol J 2024; 24:306-313. [PMID: 38681134 PMCID: PMC11052690 DOI: 10.1016/j.csbj.2024.04.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 04/10/2024] [Accepted: 04/10/2024] [Indexed: 05/01/2024] Open
Abstract
Medical biotechnology is at the forefront of scientific progress, with humanity facing a critical juncture during the pandemic. However, to maximize these benefits, governments face the complex challenge of reconciling innovation and risk. A sustainable balance is critical, as extreme measures such as blanket bans on biotechnology research could hamper progress, while unfettered research could pose an existential threat. The need for effective regulation has become apparent in the context of recent controversies surrounding pharmaceutical biotechnology. Governments face the challenge of reconciling precaution with innovation, necessitating a dual strategy fostering both principles. This paper explores the delicate dynamics of innovation and risk in pharmaceutical biotechnology, focusing on the evolving landscape in Europe, the U.S., and, notably, China. At the same time, we delve into the regulatory landscape and examine the role of the "right to science" in shaping Chinese policy. This paper further applies the right to science that has received the interests of medical biotechnology regulatory policymakers: understanding the role of scientific claims in regulating emerging technologies and analyzing the impact of major regulations on the ability to sustainably balance innovation and risk. We believe that a comprehensive global effort is needed to harmonize these two principles, highlighting the imperative of responsible governance in steering the trajectory of this powerful scientific frontier. The insights gained from the Chinese experience offer valuable implications for global policymakers facing similar challenges.

Abstract
Germline genome editing of IVF embryos is controversial because it is not directly health or lifesaving but is intended to prevent genetic diseases in yet-unborn future offspring. The following criteria are thus proposed for future clinical trials: (i) Due to medical risks, there should be cautious and judicious application while avoiding any non-essential usage, with rigorous patient counseling. (ii) Genome editing should only be performed on the entire batch of IVF embryos without initial PGT screening if all of them are expected to be affected by genetic disease. (iii) When there is a fair chance that some IVF embryos will not be affected by genetic diseases, initial PGT screening must be performed to identify unaffected embryos for transfer. (iv) IVF embryos with carrier status should not undergo germline genome editing. (v) If patients fail to conceive after the transfer of unaffected embryos, they should undergo another fresh IVF cycle rather than opt for genome editing of their remaining affected embryos. (vi) Only if the patient is unable to produce any more unaffected embryos in a fresh IVF cycle due to advanced maternal age or diminished ovarian reserves, can the genome editing of remaining affected embryos be permitted as a last resort.

Abstract
Zygotic Genome Activation (ZGA) is a crucial developmental milestone in early embryogenesis, marking the transition from maternal to embryonic control of development. This process, which varies in timing across species, involves the activation of the embryonic genome, paving the way for subsequent cell differentiation and organismal development. Recent advances in genomics and reproductive medicine have highlighted the potential of ZGA in the realm of genetic screening, providing a window into the genetic integrity of the developing embryo at its earliest stages. The intersection of ZGA and genetic screening primarily emerges in the context of preimplantation genetic diagnosis (PGD) and preimplantation genetic screening (PGS). These techniques, often employed during assisted reproductive technologies, aim to detect potential genetic abnormalities or chromosomal imbalances before embryo implantation. Given that ZGA represents the onset of embryonic gene expression, understanding its intricacies can significantly enhance the accuracy and predictive power of these screening processes. With the advent of next-generation sequencing and other high-throughput genomic techniques, detailed mapping of the transcriptomic changes during ZGA has become feasible. Such advancements have deepened our insights into the dynamics of early embryonic development and the onset of genetic disorders. As our knowledge in this realm expands, it promises to revolutionize our capabilities in detecting, understanding, and potentially rectifying genetic anomalies at the earliest stages of human life, thereby optimizing reproductive outcomes.

Abstract
As stewards of public money, government funding agencies have the obligation and responsibility to uphold the integrity of funded research. Despite an increasing amount of empirical studies examining research-related misconduct, a majority of these studies focus on retracted publications. How agencies spot funding-relevant wrongdoing and what sanctions the offenders face remain largely unexplored. This is particularly true for public funding agencies in emerging science powers. To amend this oversight, we retrieved and analyzed all publicized investigation results from China's largest basic research funding agency over the period from 2005 to 2021. Our findings reveal that both the "police patrol" and "fire alarm" approaches are used to identify misconduct and deter funding-related fraud in China. The principal triggers for investigations are journal article retractions, whistleblowing, and plagiarism detection software. Among the six funding-related misconduct types publicized and punished, the top three are: (1) fraudulent papers, (2) information fabrication and/or falsification in the research proposal, and (3) proposal plagiarism. The most common administrative sanctions are debarment and reclamation of grants. This article argues that more systematic research and cooperation among stakeholders is needed to cultivate research integrity in emerging science powers like China. Specific training and education should be provided for young scientists to help them avoid the pitfall of academic misconduct.

Abstract
As international academic exchanges and cooperation deepen, China has actively engaged in international biomedical research collaboration and achieved significant success. However, these accomplishments have been accompanied by ethical controversies and issues, with ethics dumping being a recurrently discussed focus among scholars. This paper reviews ethics dumping incidents in China's biomedical research field and analyzes the underlying causes to answer why China is often susceptible to ethics dumping. We argue that the primary reasons include weak ethical awareness among some researchers, an oversimplified research evaluation system, gaps in relevant ethics governance and oversight mechanisms, and limited capabilities of certain ethics committees. To address these issues, we propose five ethics governance recommendations: establishing refined ethics committees at various levels and types; advancing theoretical and practical research on science and technology ethics governance; strengthening legislation and regulation related to emerging science and technology; emphasizing self-regulation and capacity building of research institutions; and providing special protection and healthcare for victims of ethics dumping. The aim is to enhance China's research supervision system and prevent similar ethics dumping incidents from recurring.

Abstract
The CRISPR (clustered regularly interspaced short palindromic repeats)/Cas9 genome editing system has been a major technological breakthrough that has brought revolutionary changes to genome editing for therapeutic and diagnostic purposes and precision medicine. With the advent of the CRISPR/Cas9 system, one of the critical limiting factors has been the safe and efficient delivery of this system to cells or tissues of interest. Several approaches have been investigated to find delivery systems that can attain tissue-targeted delivery, lowering the chances of off-target editing. While viral vectors have shown promise for in vitro, in vivo and ex vivo delivery of CRISPR/Cas9, their further clinical applications have been restricted due to shortcomings including limited cargo packaging capacity, difficulties with large-scale production, immunogenicity and insertional mutagenesis. Rapid progress in nonviral delivery vectors, including the use of lipid, polymer, peptides, and inorganic nanoparticle-based delivery systems, has established nonviral delivery approaches as a viable alternative to viral vectors. This review will introduce the molecular mechanisms of the CRISPR/Cas9 gene editing system, current strategies for delivering CRISPR/Cas9-based tools, an overview of strategies for overcoming off-target genome editing, and approaches for improving genome targeting and tissue targeting. We will also highlight current developments and recent clinical trials for the delivery of CRISPR/Cas9. Finally, future directions for overcoming the limitations and adaptation of this technology for clinical trials will be discussed.

Abstract
BACKGROUND Genetic engineering has allowed a major development of research in this field, with specialists attempting to edit the human genome, after the successful editing of the genomes of plants and animals. However, human gene editing technologies are at the center of ethical debates around the world. AREAS OF UNCERTAINTY Ethical concerns about genetic editing of the human embryo raise several issues that can be viewed through the prism of optimism and reluctance leading to a number of recommendations regarding the acceptance of what may soon become a reality. DATA SOURCES A literature search was conducted through PubMed, MEDLINE, Plus, Scopus, and Web of Science (2015-2022) using combinations of keywords, including: human genome or gene editing plus ethics. ETHICS AND THERAPEUTIC ADVANCES Gene therapy is seen by researchers as a way to solve congenital diseases, multifactorial diseases in general or specific diseases such as cystic fibrosis, muscular dystrophy, or can increase resistance to HIV infection. Genome editing technologies, germline gene editing, clustered regularly interspaced short palindromic repeats gene editing technology, technologies such as zinc finger nucleases are not only advanced gene therapies that require solving technical problems, but also techniques that require complex and complete analysis of ethical problems. Genetic engineering raises many ethical concerns such as: safety concerns especially the risk of off-target effects; autonomy of the individual-with the limitation of the future generations to consent for an intervention over their genome; social justice-keeping in mind the costs of the procedures and their availability to the general population. Discussions can go further from questions such as "How can we do this?" to questions such as "Should we do this?" or "Is society ready to accept this technology and is it able to manage it rationally?" CONCLUSIONS The ethics of biomedical research should be based on global dialogue, on the involvement of experts and the public, to achieve a broad social consensus. The fundamental review of the ethics of genetics is a desire and an opportunity of the current period.

Abstract
The CRISPR/Cas9 system is a popular genome-editing tool with immense therapeutic potential. It is a simple two-component system (Cas9 protein and RNA) that recognizes the DNA sequence on the basis of RNA:DNA complementarity, and the Cas9 protein catalyzes the double-stranded break in the DNA. In the past decade, near-atomic resolution structures at various stages of the CRISPR/Cas9 DNA editing pathway have been reported along with numerous experimental and computational studies. Such studies have boosted knowledge of the genome-editing mechanism. Despite such advancements, the application of CRISPR/Cas9 in therapeutics is still limited, primarily due to off-target effects. Several studies aim at engineering high-fidelity Cas9 to minimize the off-target effects. Molecular Dynamics (MD) simulations have been an excellent complement to the experimental studies for investigating the mechanism of CRISPR/Cas9 editing in terms of structure, thermodynamics, and kinetics. MD-based studies have uncovered several important molecular aspects of Cas9, such as nucleotide binding, catalytic mechanism, and off-target effects. In this Review, the contribution of MD simulation to understand the CRISPR/Cas9 mechanism has been discussed, preceded by an overview of the history, mechanism, and structural aspects of the CRISPR/Cas9 system. These studies are important for the rational design of highly specific Cas9 and will also be extremely promising for achieving more accurate genome editing in the future.

Abstract
Ever since the publication of Derek Parfit's Reasons and Persons, bioethicists have tended to distinguish between two different ways in which reproductive technologies may have implications for the welfare of future persons. Some interventions harm or benefit particular individuals: they are "person affecting." Other interventions determine which individual, of a number of possible individuals, comes into existence: they are "identity affecting" and raise the famous "non-identity problem." For the past several decades, bioethical debate has, for the most part, proceeded on the assumption that direct genetic modification of human embryos would be person affecting. In this paper, I argue that that genome editing is highly unlikely to be person affecting for the foreseeable future and, as a result, will neither benefit nor harm edited individuals.

Abstract
In this paper, we systematically investigated and assessed China’s evolving medical biotechnology legislative and regulatory regime. 89 laws, rules, measures, guidelines, and views from 1985 to 2022 were systematically analogized and 28 were found to be involved in medical biotechnology legislation, including the recently passed Biosecurity Law. We classified the legislations and performed a comparative analysis for their legal binding based on the legal subject and extent of application, then further analyzes some of the legislative challenges in governing medical biotechnology risks in the context of China’s upgrading its regulatory and legal regime in the last 3 years. We concluded that policymakers in China have now incorporated medical biotechnology-related biosafety and biosecurity into the national strategic goals of a “People-Centered” approach to establish and foster an ecological civilization, particularly in the aftermath of the “He Jiankui affair.” Instead of relying on a patchwork of existing regulations and measures relating to the emerging field of medical biotechnology, China is attempting to integrate a patchwork of existing regulations and measures into a comprehensive legal framework, such as the constitution, National Security Law, Biosecurity Law, administrative regulations, departmental and local rules, and has begun to use the Civil Code and Criminal Law to explicitly identify actions relating to medical biotechnology. In general, China follows the “precautionary principle” as it thinks that uncertainty in science and technology should not be used to justify delaying the adoption of measures to prevent injuries or dangers, stating that whoever advances biotechnology must face the burden of proof of no harm. There would be a need to impose oversight for prevention and precaution if any biotechnology breakthrough that carries risks on which no scientific consensus has been reached. We argued that the “top-down” formulation of general objectives by the active political leadership and “bottom-up” innovation in the implementation are the keys to achieving these goals. Given the rapid advancements in medical biotechnology, countries all over the world must examine the governance landscape around biosafety and biosecurity and quickly consider options for their own comprehensive, credible, and long-lasting regulatory frameworks and experiences learned from China’s governance will help chart a scalable future roadmap.

Abstract
To date, the controversy surrounding the unknown risks and consequences of heritable genome editing has grown, with such work raising biosafety and ethical concerns for future generations. However, the current guideline of global governance is limited. In the context of the new framework for the governance of human genome editing developed by the World Health Organization (WHO) committee, this paper presents further analysis by highlighting predicaments of governance on germline engineering that merit the most attention: (1) building a scientific culture informed by a broader set of values and considerations in the internal scientific community at large, such as codes of ethics, and education, in addition to awareness-raising measures; and (2) reflecting on and institutionalizing policies in grassroots practice according to local conditions in external governance, such as the experimentalist governance, which is a multi-layered model of governance that establishes an open-ended framework from the top and offers stakeholders the freedom of discussion. The key to achieving these goals is more democratic deliberation between the public and the inclusive engagement of the global scientific community, which has been extensively used in the Biological and Toxin Weapons Convention (BTWC). On a global scale, we believe that practicing heritable human genome editing in accordance with the WHO and BTWC appears to be a good choice.

[PMID: 34394752 DOI: 10.1007/s41649-021-00167-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Revised: 02/01/2021] [Accepted: 02/02/2021] [Indexed: 01/05/2023] Open
Abstract
The discovery of clustered regularly interspaced short palindromic repeats (CRISPR) and the CRISPR-mediated protein 9 (CRISPR-Cas9) immediately revealed numerous potential therapeutic applications. Although CRISPR-Cas9 will most likely be useful for addressing issues such as genetic diseases and related medical issues, use of this modality for germline modification generates complex ethical questions regarding the safety and efficacy, human genetic enhancement, and "designer" babies. In this article, the case of the He Jiankui affair is used as an example of the potential for unregulated use of CRISPR-Cas9 technology. In 2018, Dr He Jiankui reported that he had successfully edited human embryos. This work clearly violates all international principles of bioethics. As such, the purpose of this paper is to explore the ethical challenges inherent in the use of CRISPR-Cas9 for human germline editing from the perspectives of the goals of Islamic law (Maqasid al Shari'a) and the major jurisprudential maxims (Qawaid Fiqhiyyah). We argue that from an Islamic standpoint, the therapeutic application of CRISPR-Cas9 for germline editing may be permissible if the safety and efficacy concerns are resolved and if the principles of Maqasid al-Shari'a are fulfilled.

Abstract
Human gene editing, particularly using the new CRISPR/Cas9 technology, will greatly increase the capability to make precise changes to human genomes. Human gene editing can be broken into four major categories: somatic therapy, heritable gene editing, genetic enhancement, and basic and applied research. Somatic therapy is generally well governed by national regulatory systems, so the need for global governance is less urgent. All nations are in agreement that heritable gene editing should not proceed at this time, but there is likely to be divergence if and when such procedures are shown to be safe and effective. Gene editing for enhancement purposes is not feasible today but is more controversial with the public, and many nations do not have well-developed regulatory systems for addressing genetic enhancement. Finally, different nations treat research with human embryos very differently based on deeply embedded social, cultural, ethical, and legal traditions. Several international governance mechanisms are currently in operation for human gene editing, and several other governance mechanisms have been proposed. It is unlikely that any single mechanism will alone be effective for governing human gene editing; rather, a polycentric or ecosystem approach that includes several overlapping and interacting components is likely to be necessary.

Abstract
In the event that human embryo genome editing is considered safe enough for the clinic, researchers will need to consider how to administer consent so that would-be recipients of edited embryos can make an informed decision. Informed consent will require truthfulness, sensitivity, regulatory compliance, and attention to the highest ethical standards.

Abstract
PURPOSE We have been inquiring into the diffusion process of reproductive genetic services (RGS) and the viability of geneticization in human reproduction. METHOD A 2-round modified-Delphi survey was applied amongst Israeli and Spanish experts to analyze regulatory attitudes and expectations about the future applications of RGS. We argue that an explanation of RGS diffusion based on a 'technology-push' impulse should be complemented by a 'demandpull' approach, which underscores the importance of regulatory frameworks and demand-inducing policies. The diffusion of RGS is advancing in a 'spiralshaped' process where technology acts as a cause and effect simultaneously, modulating social acceptance and redefining the notions of health and responsibility along the way. RESULTS We suggest that there is a 'grey-zone' of RGS regulations regarding four procedures: the use of germline genome modification (GGM) for severe monogenic disorders, preimplantation genetic testing (PGT) for detection of chromosomal abnormalities, PGT for multifactorial diseases, and PGT with whole-exome screening. CONCLUSIONS Although far from the geneticization of human reproduction, our findings suggest that, since techno-scientific imaginaries tend to shape regulations and thus favor the diffusion of RGS, policymakers should pay attention to those procedures by focusing on good practices and equity while providing sound information on potential risks and expected success rates. A broad and inclusive societal debate is critical for overcoming the difficulty of drawing a clear line between medical and non-medical uses of genetic selection and engineering while searching for the right balance between allowing reproductive autonomy and protecting the public interest.

Abstract
One heated argument in recent years concerns whether requiring real name supervision on social media will inhibit users’ participation in discoursing online speech. The current study explores the impact of identification, perceived anonymity, perceived risk, and information credibility on participating in discussions on moral/ethical violation events on social network sites (SNS) in China. In this study, we constructed a model based on the literature and tested it on a sample of 218 frequent SNS users. The results demonstrate the influence of identification and perception of anonymity: although the relationship between the two factors is negative, both are conducive to participation in discussion on moral/ethical violation topics, and information credibility also has a positive impact. The results confirmed the significance of risk perception on comments posted about moral/ethical violation. Our results have reference value for identity management and internet governance. Policies regarding users’ real names on the internet need to take into account the reliability of the identity authentication mechanism, as well as netizens’ perceptions of privacy about their identity and the necessity of guaranteeing content and information reliability online. We also offer some suggestions for future research, with a special emphasis on applicability to different cultures, contexts, and social networking sites.

Abstract
PURPOSE OF REVIEW Continued development of gene editing techniques has raised the real possibility of clinical application of germline gene editing. These results, as well as reports of an unethical experiment which resulted in the birth of at least two children from edited embryos in 2018, have highlighted the urgency and importance of ethical issues about translational pathways for editing of human germline cells. Charting responsible translational pathways for germline gene editing requires tackling some significant and complex ethical issues. RECENT FINDINGS A literature on development of clinical applications of germline gene editing is emerging, and several key ethical issues are coming into focus as major challenges for responsible translational pathways. SUMMARY Potential clinical utility, clinical justification, and human subjects research for germline gene editing raise outstanding ethical questions. Work on these questions will help provide guidance to researchers and clinicians and direct translational projects toward justifiable applications.

Abstract
Approximately 80% of rare and often incurable and serious conditions affect newborns and children, and roughly half of all rare diseases are considered to have an onset in childhood. Somatic gene therapies are already in clinical trials for spinal muscular atrophy, beta thalassemia, and macular degeneration. If proven to be safe and effective, could heritable genome editing be seen as a form of preventive personalized medicine and as fostering the right to health of the child? The latest calls for global moratoria on clinical applications of heritable genome editing are troubling in that they may create an illusion of control over rogue science and stifle the necessary international debate surrounding an ethically responsible translational path forward. Children are people with distinct rights and interests. An arbitrary moratorium neither fosters their best interests or health nor respects their right to benefit from the advancements of science.

Abstract
The case of twins born with genes modified by He Jiankui highlights the need for international governance of germline gene editing (GGE). This article proposes a global framework that utilizes "ordo-responsibilities." This is a pragmatic ethical approach open to pluralism and grounded in principles of human dignity and human rights. Ordo-responsibility is pragmatic in (1) accepting generally available values on a global level (e.g., human dignity, human rights) and (2) seeking achievable implementation. Genetic science is practiced globally in ways that transcend borders. As such, its practice must take account of the vast complexity of cultural, ethical, legal, and anthropological convictions. Here, we explain the basic structure of an appropriate rule-finding process, outline a possible pathway toward an international framework, and discuss minimal requirements that are needed in that endeavor. We thereby contribute to the debate on how to govern genome-editing technologies and GGE globally.

Abstract
The potential for using germline genome editing (GGE) in humans has garnered a lot of attention, both for its scientific possibilities as well as for the ethical, legal, and social challenges it ignites. The ethical debate has focused primarily on the suggestions of using GGE to establish a pregnancy (i.e., to offer it in a clinical setting), which is, to date, illegal in many jurisdictions. The use of GGE in research (where a pregnancy would not be established) has received much less attention, despite the fact that it raises serious ethical and social issues as well. Herein, we report on the analysis of informed consent forms for egg and sperm donation used in a widely publicized study where genome editing was used to correct a disease-causing genetic mutation in human embryos. Importantly, embryos were created using eggs and sperm obtained specifically for these experiments. The analysis indicates deficiencies in how the forms addressed various issues, including limited and potentially misleading information about the sensitive nature of the study, the lack of an explicit mention of genomic sequencing, as well as the poor readability of the forms. Furthermore, the arguably high compensation of U.S.$5,000 for egg donors raises questions about undue inducement to participate in research. Moreover, since the procurement of eggs involves serious health risks, it may be questioned whether research requiring such a procedure should be pursued. If such experiments are continued, donors should be informed about all relevant aspects in order to make informed decisions about participating.

Abstract
In November 2018, the announcement that genetically edited human embryos had been used for reproductive purposes caused international uproar; many observers argued that editing the human germline was unethical, particularly given the early stage of the science and the absence of appropriate oversight. We provide an overview of the implications of these events, focusing on the relevant ethical considerations for physicians addressing patient questions and concerns. The editing of the human germline for reproductive purposes should be understood against an historic backdrop of clinical research in assisted reproduction, as well as other exemplars of translational investigation. An important question raised by our growing capacity to genetically alter human embryos is how to understand the implicit social contract between science and society. To ensure that translational research continues to enjoy the historic trust placed in scientists and research organizations, it is critical that scientific and health care institutions proactively engage governments, patient advocacy organizations, and the general public in the formation of policies that guide gene editing.

Abstract
There is a continuous search for an HIV cure as the success of ART in blocking HIV replication and the role of CD4+ T cells in HIV pathogenesis and immunity do not entirely eradicate HIV. The Berlin patient, who is virus-free, serves as the best model for a 'sterilizing cure' and many experts are trying to mimic this approach in other patients. Although failures were reported among Boston and Essen patients, the setbacks have provided valuable lessons to strengthen cure strategies. Following the Berlin patient, two more patients known as London and Düsseldorf patients might be the second and third person to be cured of HIV. In all the cases, the patients underwent chemotherapy regimen due to malignancy and hematopoietic stem cell transplantation (HSCT) which required matching donors for CCR5Δ32 mutation - an approach that may not always be feasible. The emergence of newer technologies, such as long-acting slow-effective release ART (LASER ART) and CRISPR/Cas9 could potentially overcome the barriers due to HIV latency and persistency and eliminate the need for CCR5Δ32 mutation donor. Appreciating the failure and success stories learned from these HIV breakthroughs would provide some insight for future HIV eradication and cure strategies.

Abstract
A recent report from Dr He Jiankui concerning the birth of twin girls harbouring mutations engineered by CRISPR/Cas nucleases has been met with international condemnation. Beside the serious ethical concerns, there are known technical risks associated with CRISPR/Cas gene editing which further raise questions about how these events could have been allowed to occur. Numerous studies have reported unexpected genomic mutation and mosaicism following the use of CRISPR/Cas nucleases, and it is currently unclear how prevalent these disadvantageous events are and how robust and sensitive the strategies to detect these unwanted events may be. Although Dr Jiankui's study appears to have involved certain checks to ascertain these risks, the decision to implant the manipulated embryos, given these unknowns, must nonetheless be considered reckless. Here I review the technical concerns surrounding genome editing and consider the available data from Dr Jiankui in this context. Although the data remains unpublished, preventing a thorough assessment of what was performed, it seems clear that the rationale behind the undertaking was seriously flawed; the procedures involved substantial technical risks which, when added to the serious ethical concerns, fully justify the widespread criticism that the events have received.

Abstract
The HIV-1 virus (human immunodeficiency virus) affects 36.9 million people worldwide, with approximately 900000 deaths in 2017. The virus carrier can develop severe immunodeficiency since CD4+ T lymphocytes are the main target, leading to acquired immunodeficiency syndrome (AIDS). Despite advances in pharmacological treatment, it is still difficult to eliminate latent reservoirs, becoming one of the main obstacles for viral eradication. The CRISPR- (clustered regularly interspaced short palindromic repeat-) Cas system is a genome-editing method which uses a guide RNA, a complementary sequence to the interested site, recruiting a nuclease that can break the viral or the host cell genetic material. From this double-stranded break, cellular repair mechanisms are activated being able to generate deletions, insertions, or substitutions, in order to inactivate specific gene loci, leading to loss of function. The objective of this minireview is to synthesize the current knowledge on the application of CRISPR-Cas-based gene therapy for HIV-1. The strategies encompass all steps of the viral infection cycle, from inhibition of cell invasion, through viral replication and integration inhibition, to excision of the latent provirus. Off-target effects and ethical implications were also discussed to evaluate the safety of the approach and viability of its application in humans, respectively. Although preclinical and clinical tests are still needed, the recent results establish an exciting possibility of applying this technology for prophylaxis and treatment of HIV-1.

Abstract
In November 2018 a Chinese scientist claimed to have used CRISPR/Cas 9 technology to genetically modify two human embryos that were then gestated in one adult woman through an IVF pregnancy and brought to term. The twin girls are allegedly the first babies born with their prenatal genomes edited. Using both English language and Chinese supporting documents, this paper discusses the background of this human experiment, the social context of Chinese science, and the alleged ethical transgressions of its principal scientist.

Abstract
Canada's Assisted Human Reproduction Act is long overdue for Parliamentary review. We argue that the current regulation of research using human reproductive materials is not proportionate, not responsive to the uncertain threats posed to human and environmental health and safety, and is not considerate of diverse values in a democratic society. We propose tailored regulatory carve-outs for in vitro research for currently prohibited activities, such as gene editing, and for the exercise of Ministerial Discretion for access by Canadians to experimental in vivo interventions that are currently prohibited, such as mitochondrial replacement therapy. Our recommendations are bounded by constitutional constraints that recognize political and practical challenges in keeping oversight of this research under Federal jurisdiction, whether conducted in academic or private sectors. The proposed nuanced regulatory scheme should be overseen by a new national Agency, modeled on a blend of the Canadian Stem Cell Oversight Committee and Assisted Human Reproduction Canada.

Abstract
The announcement of the "CRISPR babies" reignited the debate surrounding the ethical, legal and social implications of germline gene editing. Despite having been conducted in the context of a clinical trial, Dr. Jiankui He's research appears to have violated both Chinese regulations and standard ethical procedures, as well as internationally accepted research and bioethical standards. It is within this context that our commentary surrounding the question of the enforceability of Chinese regulations in such a case. We argue that Chinese regulations do align with internationally accepted standards. Yet, the question remains, in what ways can China strengthen and update its regulatory framework to better address the benefits and challenges associated with emerging technologies, delineate clear enforcement mechanisms and specify criteria for ethics approval.

Abstract
The announcement of He Jiankui's germline editing of human embryos has been followed by a torrent of almost universal criticism of the claim on scientific and ethical grounds. That criticism is warranted. There is little room for anything other than vociferous condemnation of He's announcement. Presenting the results of groundbreaking work by press conference and YouTube is not science. The issue now is not whether the work supporting the claims reported from China was done in an ethical manner. It was not. What is required to move forward is a justification for doing germline editing in humans. Many think there is none, and prohibitions abound. If such work is justifiable, a serious, rigorous framework must be imposed that insures that such research is done following the highest ethical standards that both protect human subjects and insure public trust and support.
