Prions and Prion-like Phenomena in Epigenetic Inheritance
While epigenetic inheritance of chromatin components is, in theory, accepted as the driver of such phenomena, chromatin state inheritance per se has only been demonstrated for a few specific cases.
This NoE identified 4 areas aiming at: 1) characterizing the molecular dynamics of epigenetic systems at the single molecule and cell level, 2) linking genotypes to epigenotypes, 3) investigating how environmental, developmental and metabolic signals act upon the epigenome, and 4) understanding epigenetic inheritance through replication, mitosis and meiosis.
It marks the first time researchers have shown that a number of different classes of environmental toxicants can promote the epigenetic inheritance of ovarian disease across multiple generations.
The Drosophila Fab-7 chromosomal element conveys epigenetic inheritance during mitosis and meiosis.
In both plants and animals, epigenetic inheritance occurs across mitotic cell divisions and, at least in plants, it also occurs across meiotic divisions and fertilization.
Objective: A PubMed search for epigenetic identifies nearly 35,000 entries, yet the molecular mechanisms by which chromatin modification and gene expression patterns are actually inherited during chromosome replication mechanisms which lie at the heart of epigenetic inheritance of gene expression are still largely uncharacterised.
