Yeast epigenetics: the inheritance of histone modification states

Epigenetics, histone H3 variants, and the inheritance of chromatin states.

Histone variants and epigenetics.

Histones package and compact DNA by assembling into nucleosome core particles. Most histones are synthesized at S phase for rapid deposition behind replication forks. In addition, the replacement of histones deposited during S phase by variants that can be deposited independently of replication provide the most fundamental level of chromatin differentiation. Alternative mechanisms for depositin...

Semiconductor-based DNA sequencing of histone modification states

The recent development of a semiconductor-based, non-optical DNA sequencing technology promises scalable, low-cost and rapid sequence data production. The technology has previously been applied mainly to genomic sequencing and targeted re-sequencing. Here we demonstrate the utility of Ion Torrent semiconductor-based sequencing for sensitive, efficient and rapid chromatin immunoprecipitation fol...

Germline histone dynamics and epigenetics.

Germ cells have the same DNA sequence as somatic cells, but the processes that act on their chromatin are different. Germline chromatin undergoes a series of dramatic remodeling events during the life cycle of an organism. Different aspects of germline chromatin have been dissected in recent years, such as differences between the sex chromosomes and autosomes in histone variants and modificatio...
