WebFeb 26, 2024 · Specifically, epigenetic processes act “upon” the genome, which may open or close the chromatin to various degrees to govern access for reading DNA sequences (Figure 1). When the chromatin is opened, transcription and translation can take place; however, when the chromatin is closed, gene expression is silenced (Syzf et al., 2007). WebSeveral mechanisms are involved in epigenetic modifications to the genome that regulate gene expression, and epigenetic control of gene expression is important in development, cancer, and modulating the genomic response to environmental factors.

WebJul 14, 2024 · Therefore, during development female cells apply epigenetic changes to permanently close down all the genes on one X chromosome. This process is called ‘X-inactivation’. Our researchers are using X-inactivation as a model of epigenetic changes, to discover new ways that genes are switched on and off. Epigenetics and development WebMar 7, 2024 · While all cells have the same DNA, epigenetics determine how each cell will function, turning genes on and off so that the cells are appropriate for their role (e.g., liver, brain, heart, etc.).
