Epigenetics: Embedded bodies and the molecularisation of biography and milieu

Abstract

Abstract:The molecular biological field of epigenetics has recently attracted attention not only in biology, but also in the broader scientific community and the popular press. Commentators paint a very heterogeneous picture with some arguing that epigenetics is nothing but another aspect of gene regulation, and others enthusiastically proclaiming a paradigmatic shift in developmental biology. This article analyses a particular approach to environmental epigenetics -a subfield of epigenetics that is central to the recent excitement. The focus lies on an ethnographic analysis of research practices that enable a particular lab group to study the impact of different levels of context, for example, changes in the social and material environment, on epigenetic modification and thus phenotypic variation. The article argues that changes in the practice of doing epigenetic biology contribute to a molecularisation of biography and milieu, suggest the configuration of somatic sociality and produce a different concept of the body: the embedded body. This article concludes with a brief discussion of customary biology as a potential new research agenda at the interface of material and social inquiry.

Diverse bodies: the challenge of new theoretical approaches to medical anthropology

“…By committing to the idea of 'local biologies' talk of a stable single biological reality is challenged, not simply because it highlights variation but also constant change, as living things and their environments are continual in dialogue with each other (Brotherton and Nguyen 2013). More recently, such areas as social neuroscience and epigenetics have further supported the idea that the social and biological are constantly interacting with each other, leading to continual diversification and difference (Lock 2013;Niew€ ohner 2011).…”

The obliteration of life: depersonalization and disembodiment in the terabyte era

“…These contextually induced alterations of gene expression are semi-stable and may be transmitted across generations. For this reason, epigenomics aspires a broadening of the epistemic horizon, bringing the social and material environment (notably, early-life adversities) into molecular research (Niewöhner 2011(Niewöhner , 2015. Through epigenetics, the genome acquires a "life span" (Lappé and Landecker 2015).…”

Unreliable eating: Patterns of food adulteration in urban India

“…5 Here one can see the overlaps between food and drug, a topic that Ecks (2014) takes up in detail. 6 Plastic also informs the concept of 'plasticity', a term from the biosciences that refers to an organism's ability to vary according to its surrounding environments (see, for instance, Landecker, 2007;Niewöhner, 2011;Malabou, 2008;Papadopoulos, 2011;Rees, 2010).…”
