Impact/Purpose:

In this chapter we will present key features of DNA methylation and histone protein modifications, including the enzymes involved and the effects of these modifications on gene transcription. We will discuss the interplay of these dynamic modifications and the emerging role of noncoding RNAs in epigenetic gene regulation.

Description:

Epigenetic programming is likely to be an important mechanism underlying the lasting influence of the developmental environment on lifelong health, a concept known as the Developmental Origins of Health and Disease (DOHaD). DNA methylation, posttranslational histone protei n modifications, noncoding RNAs and recruited protein complexes are elements of the epigenetic regulation of gene transcription. These heritable but reversible changes in gene function are dynamic and labile during specific stages of the reproductive cycle and development. Epigenetic marks may be maintained throughout an individual's lifespan and can alter the life-long risk of disease; the nature of these epigenetic marks and their potential alteration by environmental factors is an area of active research. This chapter provides an overview of epigenetic regulation, particularly as it occurs as an essential component of embryo-fetal development.
