Objective
In mammals, one of the two X chromosomes is inactivated in females to enable dosage compensation for X-linked gene products. In mice, the first changes associated with X-inactivation occur during early pre-implantation embryogenesis. At the morula-blastocyst transition, paternal and maternal X chromosomes are differentially reprogrammed in the three cell lineages constitutive of the late blastocyst. In order to characterise the factors and epigenetic marks involved in this reprogramming process, we propose to compare the X chromatin structures in model cell lines derived from blastocysts where the paternal and maternal X chromosomes can be distinguished. To do this, we will analyse chromatin modifications and chromatin compaction using a polymorphic tiling array covering 3,5Mb around the X-inactivation centre – a genomic region on the X chromosome controlling initiation of X-inactivation. We will also study the nuclear organisation of the two X chromosomes using three-dimensional Fluorescence In Situ Hybridisation (3D FISH) techniques. These experiments will be repeated in pre-implantation embryos per se. This project addresses important early developmental decisions in mammalian embryology and should help to characterise the molecular principles involved in epigenetic reprogramming and genome plasticity during early embryogenesis.
