A new epigenetic editing tool is developed to activate silenced genes

Although all cells in an organism have the same genetic information, not all perform the same function, being as not all of them have the same active genes. Part of these differences in gene activity is due to DNA methylation, a process of silencing that labels genes in order to keep them "off" when they are not necessary. These labels are key epigenetic marks for the organism and are related to diseases such as cancer, since when they are uncontrolled, they can end up silencing important genes for normal cell activity.
