Why do we grow up to have the traits we do? Most 20th century scientists answered this question by referring only to our genes and our environments. But recent discoveries in the emerging field of behavioral epigenetics have revealed factors at the interface between genes and environments that also play crucial roles in development.

AbstractRecent research has revealed clock‐like patterns of epigenetic change across the life span in humans. Models describing these epigenetic changes have been dubbed “epigenetic clocks,” and they can not only predict chronological age but also reveal biological age, which measures physiological homeostasis and deterioration over the life span ...

Asthma is the most common chronic disease of childhood, and a growing body of evidence indicates that epigenetic variations may mediate the effects of environmental exposures on the development and natural history of asthma. Epigenetics is the study of mitotically or meiotically heritable changes in gene expression that occur without directly altering ...

Some of the key epigenetic regulatory mechanisms appeared early during evolution, and the acquisition of novel epigenetic regulators apparently facilitated certain evolutionary transitions. In this short review we focus mainly on the major epigenetic mechanisms that control chromatin structure and accessibility in mammalian cells.

Epigenetics is a fast moving field and our understanding of epigenetic mechanisms has dramatically improved in recent decades. We present the role that epigenetics plays in genomic control in humans; the molecular basis of this control and the role that epigenetic aberrations play in the aetiology of human disease.

Biologists have assumed that heritable variation due to DNA sequence differences (i.e., genetic variation) allows populations of organisms to be both robust and adaptable to extreme environmental conditions. Natural selection acts on the variation among different genotypes and ultimately changes the genetic composition of the population. While there is

Profound changes in the epigenetic landscape of cancer cells underlie the development of human malignancies. These changes include large-scale DNA methylation changes throughout the genome as well as alterations in the compendium of post-translational chromatin modifications. Epigenetic aberrations impact multiple steps during tumorigenesis, ultimately

Current Opinion in Genetics & Development, 2008
Our knowledge of the mechanisms that specify and propagate epigenetic states of gene expression is expanding rapidly; however, the significance of variation in epigenetic states at the population level remains largely unexplored. Population epigenetics, emerging as an active subfield at the interface of molecular genetics, genomics, and population ...
