Transgenerational Epigenetic Inheritance 1. Parental allele-specific imprinting There are a small subset of genes called imprint genes. Normally, we have two 2. The agouti mouse Examples of transgenerational epigenetic inheritance within endogenous genes, other than imprinted 3. Environmental Long before the terms “transgenerational” and “epigenetic” were in widespread use , the first examples of epigenetic inheritance were described in plants. Following her discovery of transposable elements, Barbara McClintock recognized that Activator and Suppressor Mutator transposons in maize cycled between active and silent phases and that these phases could be inherited across generations ( In the ensuing decades it has been shown that epigenetic transgenerational inheritance of disease and phenotypic variation is relatively common in plants, where mitotically stable epigenetic changes can be transmitted through the germline to alter genome activity independently of DNA gene sequences in the offspring (Schmitz and Ecker, 2012; Weigel and Colot, 2012).

that underlie epigenetic inheritance. We present a comprehensive review of transgenerational cellular epigenetic inheritance among different taxa in the form of a table, and discuss the data contained therein. The analysis of these data shows that epigenetic inheritance is ubiquitous and suggests lines

First, because transgenerational epigenetic inheritance has to be maintained for several generations, longitudinal multigenerational studies are required … 2013-12-01 Transgenerational epigenetic inheritance provides a mechanism by which environmental exposures and lifestyle decisions can affect the offspring directly through the gamete. It is this pattern of inheritance that has shed light on the fact that preconception lifestyle decisions that a father makes are significant because they can significantly impact the offspring.

In principle, epigenetic inheritance and germline reprogram-ming are two sides of the same coin. Germline reprogramming facilitates totipotency of the zygote, a cornerstone of develop-mental biology since the concept of ‘‘epigenesis’’ was ﬁrst pro- 2018-09-01 · Several approaches have been undertaken to explore transgenerational epigenetic inheritance in multigenerational human studies, including recruiting the offspring of birth cohort participants who are now reaching reproductive age, recruiting offspring/grandoffspring of adult cohorts, and using offspring recall and/or registry data to determine phenotype and/or exposures in parental generations. While a “bird’s-eye view” of a topic can often provide colossal insight, the opposite perspective can sometimes be just as useful! Recently, two fascinating studies of transgenerational epigenetic inheritance have taken a “worm’s-eye view” of this research area to deepen our understanding of this complex mechanism in the model nematode worm C. elegans.

Transgenerational epigenetic inheritance in mice Although epigenetic states, once established, are main-tained for the life of the organism, it is rare for these states to be passed to the next generation. Between generations, the epigenetic state of the genome undergoes two dynamic reprogramming events, ﬁrst in the gametes of the parent Epigenetic Transgenerational Inheritance The definition of epigenetic transgenerational inheritance is ‘germline-mediated inheritance of epigenetic information be-tween generations in the absence of continued direct environ-mental influences that leads to phenotypic variation’ [3, 31] (Table 1). 2015-01-22 · Transgenerational epigenetic inheritance has gained increased attention due to the possibility that exposure to environmental contaminants induce diseases that propagate across generations through epigenomic alterations in gametes.
