Imprinting gene regulation: Importance of a long non-coding RNA and of DNA methylation levels at an essential CTCF binding site
The Dlk1-Meg3-Dio3 domain is imprinted. Scientists at the IGMM and the I2BC have determined that Meg3 long non-coding RNA, as well as DNA methylation levels at an essential CTCF binding site in the domain, control Dlk1 imprinting in cis.

Epigenetics: combining flexible and rigid regions into a single structure to ensure genome replication and stability
The AMIG team at I2BC, in collaboration with teams from the Institut Curie and the Synchrotron Soleil, shows that the CAF-1 protein combines in its spatial organization flexible regions and rigid modules to deposit histones on DNA and effectively couple this process to DNA synthesis.

A Fatty Acid Anabolic Pathway in Specialized-Cells Sustains a Remote Signal that Controls Egg Activation in Drosophila
While egg activation, i.e. oocyte to embryo transition, was not known to depend on physiological non-genital signal, this study shows that in Drosophila it depends on a very-long-chain-fatty-acid produced in the oenocytes (lipid metabolism specialized cells).
