(An example of this is X-inactivation, when one of the two X chromosomes in the cell of a female animal is inactivated.) One way to appreciate the importance of these epigenetic mechanisms is to ask ...

Epigenetics involves genetic control by factors ... Inhibitors of DNA methylation can reactivate genes that have been silenced. Two examples of these types of drugs are 5-azacytidine and 5-aza ...

In this article, I give examples of how epigenetic phenomena are studied and interpreted, and I propose a revised definition that embodies contemporary usage of the word. Figure 1: Frontal view of ...

The integration of genetic and epigenetic studies can reinforce the strengths of both (Figure 2C). For example, changes in DNA methylation might occur at a DMR that is in turn regulated by genetic ...

Animal studies have established that harmful epigenetic changes can be caused by chemicals in cigarettes or pesticides, for example, and other studies now abound pointing to environmental stresses as ...

In studies that document parent-to-child epigenetic inheritance, it's not clear what's being passed on, and understanding it molecularly is very complicated. We have a specific example of ...

According to Dr. Horvath, the UCLA research points to an epigenetic explanation for Latinos' longer life spans. For example, the biological clock measured Latino women's age as 2.4 years younger ...

The mice are Agouti Viable Yellow, naturally occurring mutants, which, though genetically identical, have coats that vary in color—a phenomenon that researchers have long studied as an example of ...

Research into the most prevalent tumors in developing countries significantly lags behind research into those cancers that ...
