Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

This important study advances a new computational approach to measure and visualize gene expression specificity across different tissues and cell types. The framework is potentially helpful for ...

Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

Essentially all cells in an organism's body have the same genetic blueprint, or genome, but the set of genes that are actively expressed at any given time in a cell determines what type of cell it ...

A patient walks into a thoracic surgery consultation with a small lung tumor, stage I on every scan, and every conventional ...
