Using chromatin dynamics to understand transcriptional regulation and genetic variance
Abstract/Contents
- Abstract
- The genome is the same in every cell of an organism, but complex organisms have multiple cell types. This is due to the epigenome specifying a cell's transcriptional state resulting in distinct cell identities. Despite 98.5% of the human genome is non-coding and the site of epigenomic activity, which specifies instructions for regulating transcription of the coding region, relatively little is known about its function. A major hurdle with studying non-coding regulatory elements is identifying their distal gene and regulatory targets. Here, I solve this issue by using the three-dimensional chromatin conformation to identify targets that are in close physical proximity of the regulatory element. By integrating data on the three-dimensional chromatin state with other epigenomic measures including the open chromatin regions, transcription factor binding sites, and histone modifications I provide genome-wide insight into how the epigenome establishes the transcriptional state of the cell. In addition, I have developed a new method for prioritizing non-coding genetic variants in complex phenotypes. I validated this method in the context of Type 1 Diabetes and craniofacial disorders. In this dissertation, I demonstrate how data integration of multiple measurements of the epigenome and transcriptome provides insight into methods of transcriptional regulation and how this regulation is influenced by genetic variance.
