چکیده

Epigenetic regulation modulates gene expression without altering the DNA sequence to facilitate rapid adjustments to dynamically changing environmental conditions. The formation of an epigenetic memory allows passing on this information to subsequent generations. Here we propose that epigenetic memories formed by adverse environmental conditions and stress represent a critical determinant of health and disease in the F3 generation and beyond. Transgenerational programming of epigenetic regulation may represent a key to understand adult-onset complex disease pathogenesis and cumulative effects of life span and familial disease etiology. Ultimately, the mechanisms of generating an epigenetic memory may become of potentially promising diagnostic and therapeutic relevance due to their reversible nature. Exploring the role of environmental factors, such as stress, in causing variations in epigenetic profiles may lead to new avenues of personalized, preventive medicine based on epigenetic signatures and interventions.

Manifest Destiny and American Identity in Cormac McCarthy’s Blood Meridian

McCarthy scholarship has predominantly tended to stress the writer’s revisionism with regard to his rendering of the myth of the American West in Blood Meridian (1985). McCarthy’s novel has beenmainlyhailed as a critique of the violence of manifest destiny. This study aims to delineate aspects of McCarthy’s narrative which resist the predominant view of him as a revisionist. In this re...

Importance of Genomic Imprinting in the Evolution and Development of the Maternal Brain

It was the French reproductive biologist, Alfred Jost (1970), who proposed that mammalian sexual differentiation is biased in a female direction and masculine characteristics are imposed on an essentially female life plan. The reproductive success of mammals places a considerable burden of time and energy on the matriline, with some 95 % of female adult life committed to pregnancy, lactation an...

Onm-19: Role of Epigenetic in Transgenerarional Disease

Epigenetic alterations have been related to many biological processes and disease; however, the global epigenetic status of most cell types has not been investigated yet in detail. The ability of environmental factors to promote a phenotype or disease state not only in the individual exposed but also in subsequent progeny for successive generations is termed transgenerational inheritance. The m...

Non-genomic transgenerational inheritance of disease risk.

That there is a heritable or familial component of susceptibility to chronic non-communicable diseases such as type 2 diabetes, obesity and cardiovascular disease is well established, but there is increasing evidence that some elements of such heritability are transmitted non-genomically and that the processes whereby environmental influences act during early development to shape disease risk i...

Developmental origins of epigenetic transgenerational inheritance

Environmental factors can induce epigenetic alterations in the germ cells that can potentially be transmitted transgenerationally. This non-genetic form of inheritance is termed epigenetic transgenerational inheritance and has been shown in a variety of species including plants, flies, worms, fish, rodents, pigs, and humans. This phenomenon operates during specific critical windows of exposure,...
