Mechanisms of epigenetic inheritance.
The mechanisms by which stable gene expression patterns are inherited during cell division are not well understood. Chromatin is subject to a number of covalent modifications and it is generally believed that the transfer of these modifications between cell generations plays a critical role in inheritance, though how this occurs is a matter of debate. In one proposed model, replication of chrom...
متن کاملTransgenerational Epigenetic Inheritance
Recent fi ndings in the emerging fi eld of transgenerational epigenetic inheritance suggest that the lifestyle choices and experiences of an individual have biological implications for offspring not yet conceived. Studies show that diet, drugs, and even social experiences can lead to life-long changes in gene expression. Some changes in gene expression are passed down to future generations. The...

متن کاملEpigenetic inheritance of centromeres.
Centromeres of higher eukaryotes are epigenetically maintained; however, the mechanism that underlies centromere inheritance is unknown. Centromere identity and inheritance require the assembly of nucleosomes containing the CenH3 histone variant in place of canonical H3. Work from our laboratory has led to the proposal that epigenetic inheritance of centromeres evolved as adaptations of CenH3 a...
متن کاملInheritance of epigenetic chromatin silencing.
Maintenance of alternative chromatin states through cell divisions pose some fundamental constraints on the dynamics of histone modifications. In this paper, we study the systems biology of epigenetic inheritance by defining and analyzing general classes of mathematical models. We discuss how the number of modification states involved plays an essential role in the stability of epigenetic state...
