DESCRIPTION (provided by applicant): Recently, genomes have been recognized to adopt preferred physical architectures that are evolutionarily conserved and cell type specific. We developed a method for characterizing long-range inter- and intra- chromosomal interactions on a genome-wide scale. Our method is based on chromatin conformation capture (3C) but unlike 3C (or other derivative technologies), makes no a priori assumptions regarding interacting genetic elements. Due to the large size of mammalian genomes we initially validated our approach in haploid Saccharomyces cerevisiae. In this application we propose to use this method to understand the relationship between genome architecture and allele specific expression in mammalian development.

描述（由申请人提供）：最近，已经认识到基因组采用进化保守和细胞类型特异性的优选物理结构。我们开发了一种在全基因组范围内表征染色体间和染色体内长期相互作用的方法。我们的方法是基于染色质构象捕获（3C），但与3C（或其他衍生技术）不同，没有关于相互作用的遗传元件的先验假设。由于哺乳动物基因组的大尺寸，我们最初在单倍体酿酒酵母中验证了我们的方法。在本申请中，我们建议使用这种方法来了解哺乳动物发育中基因组结构和等位基因特异性表达之间的关系。
