Epigenetic Profiling Of Mammalian Retrotransposons, Arundhati Bakshi

LSU Doctoral Dissertations

Over evolutionary time, mammalian genomes have accumulated a large number of retrotransposons, making up about half of the genome in any given species. These retrotransposons are typically repressed by epigenetic mechanisms, one of the main ones being DNA methylation. It is well known that improper DNA methylation of retrotransposons can have unwanted consequences on nearby gene expression, and hypomethylation of retrotransposons has been frequently observed in various cancers. Nevertheless, it has been notoriously difficult to study retrotransposon loci individually due to the highly repetitive nature of their sequences. To address this issue, we have developed a novel protocol termed HT-TREBS …
