Developmental programming and epigenetics.
The ways in which epigenetic modifications fix the effects of early environmental events, ensuring sustained responses to transient stimuli that result in modified gene expression patterns and phenotypes later in life, are a topic of considerable interest. This article focuses on recently discovered mechanisms and calls into question prevailing views about the dynamics, positions, and functions...
متن کاملEpigenetics and Neural Developmental Disorders
Neural developmental disorders, such as autism, Rett Syndrome, Fragile X syndrome, and Angelman syndrome manifest during early postnatal neural development. Although the genes responsible for some of these disorders have been identified, how the mutations of these genes affect neural development is currently unclear. Emerging evidence suggest that these disorders share common underlying defects...
متن کاملOocyte developmental competence and embryo quality: distinction and new perspectives
In vitro embryo production is the cornerstone of infertility treatment in human and is increasingly used in cattle to propagate high genetic merit animals. To increase its efficiency, many different approaches have been tested all of which stem from the concepts of oocyte quality and developmental competence. Presented here are recently reported findings and perspectives related to bovine oocyt...
متن کاملEpigenetics and developmental plasticity across species.
Plasticity is a typical feature of development and can lead to divergent phenotypes. There is increasing evidence that epigenetic mechanisms, such as DNA methylation, are present across species, are modifiable by the environment, and are involved in developmental plasticity. Thus, in the context of the concept of developmental homology, epigenetic mechanisms may serve to create a process homolo...
متن کاملEpigenetics in Developmental Disorder: ADHD and Endophenotypes.
Heterogeneity in attention-deficit/hyperactivity disorder (ADHD), with complex interactive operations of genetic and environmental factors, is expressed in a variety of disorder manifestations: severity, co-morbidities of symptoms, and the effects of genes on phenotypes. Neurodevelopmental influences of genomic imprinting have set the stage for the structural-physiological variations that modul...
