Epigenetics In Transgenerational Responses To Environmental Impacts: Facts And Gaps ebook.ecog-obesity.eu/chapter-biology/epigenetics-in-transgenerational-responses-to-environmental- impacts-facts-and-gaps

Environmental epigenetic transgenerational inheritance and somatic epigenetic mitotic stability.

The majority of environmental factors can not modify DNA sequence, but can influence the epigenome. The mitotic stability of the epigenome and ability of environmental epigenetics to influence phenotypic variation and disease, suggests environmental epigenetics will have a critical role in disease etiology and biological areas such as evolutionary biology. The current review presents the molecu...

Transgenerational Epigenetic Inheritance in Animals

with abiotic and biotic components of their surroundings. Whereas many and perhaps most of the encounters pass with transient changes at the molecular and metabolic levels, some have a profound impact on the phenotypic appearance of an organism and, more importantly, on the phenotypic appearance of their progeny. Since genetic changes are rare and random in nature, their influence on species or...

Environmentally induced epigenetic transgenerational inheritance of sperm epimutations promote genetic mutations

A variety of environmental factors have been shown to induce the epigenetic transgenerational inheritance of disease and phenotypic variation. This involves the germline transmission of epigenetic information between generations. Exposure specific transgenerational sperm epimutations have been previously observed. The current study was designed to investigate the potential role genetic mutation...
