Epigenetics: Making a Mark

The Untapped Information of the Epigenome

The complexity of the epigenome suggests a wealth of untapped biological information and regulatory potential that could be game changing for cellular engineering and biomedical interventions.

Unlocking Access to DNA in Chromatin

Scientists must learn how to open and manipulate chromatin to gain complete access to eukaryotic DNA for genome engineering.

Single-Cell Epigenetic Technology and Applications

This article highlights developments in single-cell epigenomic monitoring and modulating tools, as well as advances in synthetic epigenetic circuits. These tools are used in important biomedical and industrial applications.

Influence of Epigenetics on Bioprocessing

Harnessing and applying epigenetics in bioprocessing systems may improve cell line development, productivity, and product quality.
