Histone H2A C-terminus regulates chromatin dynamics, remodeling, and histone H1 binding
Donaldson, Maria Christine. Epigenetics plays an important role in cancer development and progression. Cancer cells hijack the epigenome by modifying the histone protein units responsible for packaging DNA, or by modifying the DNA itself, resulting in changes to chromatin topology and transcriptional programming within the cell. In this thesis, I report our investigation to uncover the mechanisms of epigenetic regulation and how epigenetic control of transcriptional programming goes awry in cancer. We investigate these processes in two separate contexts. In our first study, we investigate the mechanisms by which EZH2 oncogenic mutations alter structure and function of topologically associating domains in non-Hodgkin lymphoma. The process of chromatin folding leads to a systematic arrangement of hierarchical structural and regulatory elements found within the nucleus.

Genetics is a branch of biology concerned with the study of genes , genetic variation , and heredity in organisms. Though heredity had been observed for millennia, Gregor Mendel , Moravian scientist and Augustinian friar working in the 19th century in Brno , was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring. He observed that organisms pea plants inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded beyond inheritance to studying the function and behavior of genes.
