Chemical modifications such as DNA methylation control mammalian genes, serving as bookmarks for when a gene should be used — a phenomenon known as epigenetics.
Unravelling the epigenetic control of the lactase gene involved a collaborative effort of CAMH, University of Toronto, the Hospital for Sick Children, Vilnius University and the Lithuanian University of Health Sciences.
In light of this shortcoming, some investigators see room for an increased focus on an alternative explanation for heritable traits: epigenetics, the molecular processes that control a gene's potential to act.
The teams next looked for what might control the epigenetic changes.
One such surprise was the relative importance of two types of epigenetic control switches for retinal development.
The readability of genes is controlled by epigenetic factors, namely factors which do not influence the gene sequence directly, but rather cause certain genes and chromosomal segments to be packed in different densities — and thus make them accessible for reading.
The specific pattern of epigenetic marks in a cell type specifies identity and this epigenetic control is vital to what makes our cells different, for example a skin cell from a liver cell, when they all contain the same genetic instructions.
Joining forces with dermatologists and oncologists from the University Hospital in Zurich and backed by the University Research Priority Program «Translational Cancer Research,» Sommer's team was able to demonstrate that, in melanoma cells, the epigenetic factor EZH2 controls genes that govern tumor growth as well as genes that are important for the formation of metastases.
This is both a useful tool for giving us a better understanding of the genetic and epigenetic program controlling the self - renewal of stem cells, and on a practical side, it could allow us to inexpensively produce large numbers of immune cells, which could then be used for regenerative medicine or immune therapy.»
Recent studies have expanded the search for genetic links from identifying genes toward epigenetics, the study of factors that control gene expression and looks at chemical modifications of DNA and the proteins associated with it.
«Mom's in control, even before you're born: Egg's epigenetic «blueprint» important for placenta development in pregnancy.»
Understanding these pathways, and the identification of the key proteins that control the ability of cancer cells to reprogram their metabolism through biochemical, and epigenetic or genetic alterations that make them resistant to therapies, is of paramount importance for the design of more targeted and therefore less toxic therapies.
However, 15,627 CpG sites in / near ∼ 30 % of all genes exhibited differential methylation in adipose tissue from a case - control cohort of unrelated individuals, supporting a key role for epigenetic modifications in T2D patients.
