Characterizing Epigenetic Regulation In The Developing Chicken Retina, Bejan Abbas Rasoul
Characterizing Epigenetic Regulation In The Developing Chicken Retina, Bejan Abbas Rasoul
Masters Theses, 2010-2019
The retina, the sensory neuronal tissue within the eye, is composed of three layers of neuronal cells connected by two synaptic layers lining the inside of the anterior portion of the eye. Multipotent retinal precursor cells are genetically homogeneous and differentiate into mature retinal neurons due to differential gene expression. Differences in gene expression have been correlated with epigenetic modifications such as DNA methylation. DNA methylation of upstream regulatory elements is associated with transcriptional silencing of gene expression. Years of research in retinal development has identified the numerous genes expressed during the main steps of retinal development, however, it is …
Structural And Functional Characterization Of The Mbd2-Nurd Co-Repressor Complex, Megha Desai
Structural And Functional Characterization Of The Mbd2-Nurd Co-Repressor Complex, Megha Desai
Theses and Dissertations
The MBD2-NuRD co-repressor complex is an epigenetic regulator of the developmental silencing of embryonic and fetal β-type globin genes in adult erythroid cells as well as aberrant methylation-dependent silencing of tumor suppressor genes in neoplastic diseases. Biochemical characterization of the MBD2-NuRD complex in chicken erythroid cells identified RbAp46/48, HDAC1/2, MTA1/2/3, p66α/β, Mi2α/β and MBD2 to comprise this multi-protein complex.
In the work presented in Chapter 2, we have pursued biophysical and molecular studies to describe a previously uncharacterized domain of human MBD2 (MBD2IDR). Biophysical analyses show that MBD2IDR is an intrinsically disordered region (IDR). Despite this inherent …
