The pace of discovery in the field of human genetics has increased exponentially in the last 30 years. We have witnessed the completion of the Human Genome Project, the identification of hundreds of disease-causing genes, and the dawn of genomic medicine (clinical care based on genomic information). Reduction of DNA sequencing costs, thanks to the so-called "next generation sequencing" technologies, is driving a shift towards the era of "personal genomes", but scientific as well as ethical challenges ahead are countless. We provide an overview on the classification of genetic tests, on informed consent procedures in the context of genetic counseling, and on specific ethical issues raised by the implementation of new DNA sequencing technologies.

Genomic medicine is an emerging practice that followed the completion of the Human Genome Project and that considers genomic information about an individual in the provision of their clinical care. Large and start-up direct-to-consumer genetic testing companies like Ancestry, 23andMe, Luna DNA, and Nebula Genomics have capitalized on findings from the Human Genome Project by offering genetic health testing services to consumers without a clinical intermediary. Genomic medicine is thus further propelled by unprecedented supply and demand market forces driven by direct-to-consumer genetic testing companies. As government entities like the National Human Genome Research Institute question how genomics can be implemented into routine medical practice to prevent disease and improve the health of all members of a diverse community, we believe that stakeholders must first examine how and scenarios in which stakeholders can become motivated to share or receive genomic information. In this commentary, we discuss consumers three scenarios: satisfying personal curiosity, providing a social good, and receiving a financial return. We examine these motivations based on recent events and current avenues through which have engaged or can engage in genomic data sharing via private, secure (e.g. centralized genomic databases and de-centralized platforms like blockchain) and public, unsecure platforms (e.g. open platforms that are publicly available online). By examining these scenarios, we can likely determine how various stakeholders, such as consumers, might prefer to extract value from genomic information and how privacy preferences among those stakeholders might vary depending on how they seek to use or share genomic information. From there, one can recommend best practices to promote transparency and uphold privacy standards and expectations among stakeholders engaged in genomic medicine.

For all its biological importance, DNA is a fragile molecule so extracting it is a difficult process. ‘How to read the book of life’ explains the techniques required to sequence DNA. It begins by explaining the techniques developed for protein and RNA sequencing by Frederick Sanger, Robert Holley, and Carl Woese that were then developed further for DNA sequencing. Following the success of the Human Genome Project, the next generation of DNA sequencing was developed in the mid-2000s. Pyrosequencing was capable of generating orders of magnitude more data at a fraction of the cost, but was superceded within a decade by semiconductor sequencing, reversible chain-termination sequencing, and single-molecule sequencing.

In the last two decades, RNA post-transcriptional modifications, including RNA editing, have been the subject of increasing interest among the scientific community. The efforts of the Human Genome Project combined with the development of new sequencing technologies and dedicated bioinformatic approaches created to detect and profile RNA transcripts have served to further our understanding of RNA editing. Investigators have determined that non-coding RNA (ncRNA) A-to-I editing is often deregulated in cancer. This discovery has led to an increased number of published studies in the field. However, the eventual clinical application for these findings remains a work in progress. In this review, we provide an overview of the ncRNA editing phenomenon in cancer. We discuss the bioinformatic strategies for RNA editing detection as well as the potential roles for ncRNA A to I editing in tumor immunity and as clinical biomarkers.

At the beginning of this century, the Human Genome Project produced the first drafts of the human genome sequence. Following this, large-scale functional genomics studies were initiated to understand the molecular basis underlying the translation of the instructions encoded in the genome into the biological traits of organisms. Instrumental in the ensuing revolution in functional genomics were the rapid advances in massively parallel sequencing technologies as well as the development of a wide diversity of protocols that make use of these technologies to understand cellular behavior at the molecular level. Here, we review recent advances in functional genomic methods, discuss some of their current capabilities and limitations, and briefly sketch future directions within the field.

The 1953 discovery of the DNA double-helical structure by James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin, represented one of the most significant advances in the biomedical world (Watson and Crick 1953; Maddox 2003). Almost half a century after this landmark event, in February 2001, the initial draft sequences of the human genome were published (Lander et al., 2001; Venter et al., 2001) and, in April 2003, the International Human Genome Sequencing Consortium reported the completion of the Human Genome Project, a massive international collaborative endeavor that started in 1990 and is thought to represent the most ambitious undertaking in the history of biology (Collins et al., 2003; Thangadurai, 2004; National Human Genome Research Institute). The Human Genome Project provided a plethora of genetic and genomic information that significantly changed our perspectives on biomedical and social sciences. The sequencing of the first human genome was a 13-year, 2.7-billion-dollar effort that relied on the automated Sanger (dideoxy or chain termination) method, which was developed in 1977, around the same time as the Maxam-Gilbert (chemical) sequencing, and subsequently became the most frequently used approach for several decades (Sanger et al., 1975; Maxam & Gilbert, 1977; Sanger et al., 1977). The new generations of DNA sequencing technologies, known as next-generation (second generation) and next-next-generation (third generation) sequencing, which started to be commercialized in 2005, enabled the cost-effective sequencing of large chromosomal regions during progressively shorter time frames, and opened the possibility for new applications, such as the sequencing of single-cell genomes (Service, 2006; Blow, 2008; Morozova and Marra, 2008; Metzker, 2010).

Background: Ethical issues arise daily in the delivery of palliative care. Despite much (largely theoretical) literature, evidence from specialist palliative care practitioners about day-to-day ethical challenges has not previously been synthesised. This evidence is crucial to inform education and adequately support staff. Aim: To synthesise the evidence regarding the ethical challenges which specialist palliative care practitioners encounter during clinical practice. Design: Systematic review with narrative synthesis (PROSPERO registration CRD42018105365). Quality was dual-assessed using the Mixed-Methods Appraisal Tool. Tabulation, textural description, concept mapping and thematic synthesis were used to develop and present the narrative. Data sources: Seven databases (MEDLINE, Philosopher’s Index, EMBASE, PsycINFO, LILACS, Web of Science and CINAHL) were searched from inception to December 2019 without language limits. Eligible papers reported original research using inductive methods to describe practitioner-reported ethical challenges. Results: A total of 8074 records were screened. Thirteen studies from nine countries were included. Challenges were organised into six themes: application of ethical principles; delivering clinical care; working with families; engaging with institutional structures and values; navigating societal values and expectations; philosophy of palliative care. Challenges related to specific scenarios/contexts rather than the application of general ethical principles, and occurred at all levels (bedside, institution, society, policy). Conclusion: Palliative care practitioners encounter a broad range of contextual ethical challenges, many of which are not represented in palliative care ethics training resources, for example, navigating institutional policies, resource allocation and inter-professional conflict. Findings have implications for supporting ethical practice and training practitioners. The lack of low- and middle- income country data needs addressing.

Abstract DNA present in all our cells acts as a template by which cells are built. The human genome project, reading the code of the DNA within our cells, completed in 2003, is undoubtedly one of the great achievements of modern bioscience. Our ability to achieve this and to further understand and manipulate DNA has been tightly linked to our understanding of the bacterial and viral world. Outside of the science, the ability to understand and manipulate this code has far-reaching implications for society. In this article, we explore some of the basic techniques that enable us to read, copy and manipulate DNA sequences alongside a brief consideration of some of the implications for society.
