| epigenetics | <study> The study of mechanisms involved in the production of phenotypic complexity in morphogenesis. According to the epigenetic view of differentiation, the cell makes a series of choices (some of which may have no obvious phonotypic expression and are spoken of as determination events) that lead to the eventual differentiated state. Thus, selective gene repression or derepression at an early stage in differentiation will have a wide ranging consequence in restricting the possible fate of the cell. (07 May 1998) |

Any heritable influence (in the progeny of cells or of individuals) on gene activity, unaccompanied by a change in DNA sequence.

| epigenetics |
the study of changes in gene silencing that occur without changes in the genes themselves. Many genes in the body are permanently turned off as part of normal development. But sometimes that process goes awry, turning off genes that should otherwise remain active. This field of study and its associated therapies aims to switch these genes back on. It is a new approach to the treatment of aging, inherited diseases and cancer.
