The consideration of racial differences in the biology of disease and treatment options is a hallmark of modern medicine. However, this time-honored medical tradition has no scientific basis, and the premise itself, that is, the existence of biological differences between the commonly known races, is false inasmuch as races are only sociocultural constructions. It is time to rid medical research of the highly damaging exercise of searching for supposed racial differences in the biological manifestations of disease. The practice not only (...) condoned but required by the National Institutes of Health of utilizing racial identification as a demographic characteristic with assumed biological implications is at best badly flawed, and at worst unintentionally contributes to perpetuating the fallacy of natural differences between persons of different skin color, which has been used in the past to advance the cause of racial discrimination.

Recent findings in epigenetics have been attracting much attention from social scientists and bioethicists because they reveal the molecular mechanisms by which exposure to socioenvironmental factors, such as pollutants and social adversity, can influence the expression of genes throughout life. Most surprisingly, some epigenetic modifications may also be heritable via germ cells across generations. Epigenetics may be the missing molecular evidence of the importance of using preventive strategies at the policy level to reduce the incidence and prevalence of common diseases. (...) But while this “policy translation” of epigenetics introduces new arguments in favor of public health strategies and policy-making, a more “clinical translation” of epigenetics is also emerging. It focuses on the biochemical mechanisms and epigenetic variants at the origin of disease, leading to novel biomedical means of assessing epigenetic susceptibility and reversing detrimental epigenetic variants. In this paper, we argue that the impetus to create new biomedical interventions to manipulate and reverse epigenetic variants is likely to garner more attention than effective social and public health interventions and therefore also to garner a greater share of limited public resources. This is likely to happen because of the current biopolitical context in which scientific findings are translated. This contemporary neoliberal “regime of truth,” to use a term from Michel Foucault, greatly influences the ways in which knowledge is being interpreted and implemented. Building on sociologist Thomas Lemke's Foucauldian “analytics of biopolitics” and on literature from the field of science and technology studies, we present two sociological trends that may impede the policy translation of epigenetics: molecularization and biomedicalization. These trends, we argue, are likely to favor the clinical translation of epigenetics—in other words, the development of new clinical tools fostering what has been called “personalized” or “precision” medicine. In addition, we argue that an overemphasized clinical translation of epigenetics may further reinforce this biopolitical landscape through four processes closely related to neoliberal pathways of thinking: the internalization and isolation of socioenvironmental determinants of health and increased opportunities for commodification and technologicalization of health care interventions.

A rich literature in public health has demonstrated that health is strongly influenced by a host of environmental factors that can vary according to social, economic, geographic, cultural or physical contexts. Bioethicists should, we argue, recognize this and – where appropriate – work to integrate environmental concerns into their field of study and their ethical deliberations. In this article, we present an argument grounded in scientific research at the molecular level that will be familiar to – and so hopefully more (...) persuasive for – the biomedically-inclined in the bioethics community. Specifically, we argue that the relatively new field of molecular epigenetics provides novel information that should serve as additional justification for expanding the scope of bioethics to include environmental and public health concerns. We begin by presenting two distinct visions of bioethics: the individualistic and rights-oriented and the communitarian and responsibility-oriented. We follow with a description of biochemical characteristics distinguishing epigenetics from genetics, in order to emphasize the very close relationship that exists between the environment and gene expression. This then leads to a discussion of the importance of the environment in determining individual and population health, which, we argue, should shift bioethics towards a Potterian view that promotes a communitarian-based sense of responsibility for the environment, in order to fully account for justice considerations and improve public health.
