Genomic imprinting is an epigenetic process by which certain genes are expressed in a parent-of-origin-specific manner.

The activity of specific piRNAs in the epigenetic process also requires interactions between piwi proteins and HP1a, as well as other factors.

The caste differentiation occurs through an epigenetic process; non-heritable factors contributing to gene expression.

This volume represents a compilation of our current understanding about the key aspects of epigenetic processes in the brain and their role in behavior.

As it turns out, epigenetic processes play a crucial role in regulating the decision to adopt a stem, progenitor, or mature cell fate.

The first question that can be asked is the extent and complexity of the role of epigenetic processes in the determination of cell fate.

A final question to ask concerns the role of cell signaling in influencing the epigenetic processes governing differentiation.

DNA methylation and histone modification are among the best characterized epigenetic processes (Russell 2010 p. 475).

As the parent ages, more and more errors may occur in the epigenetic process.

Gene silencing is a general term describing epigenetic processes of gene regulation.
