Characterization Of Methylated Histone Modifications During Simian Virus 40 Early Transcription, Jacob Otto Haugen

Theses and Dissertations

Modifications of histone proteins play an important role in transcription. These modifications regulate how chromatin is compacted by the histone proteins and either made available for transcription or prevents transcription machinery from proceeding. The modifications can be added or removed by histone acetyltransferases and histone methyltransferases for the former, and histone deacetylates and demethylases for the latter. To explore the dynamicity of these modifications we used the simple but effective Simian Virus 40 (SV40) model. SV40 continues to be an important tool in understanding eukaryotic transcription. It experiences similar processes as cellular chromatin, utilizing host proteins to propagate its own …

Chronic pain often includes periods of transient amelioration and even remission that alternate with severe relapsing pain. While most research on chronic pain has focused on pain development and maintenance, there is a critical unmet need to better understand the mechanisms that underlie pain remission and relapse. We found that interleukin (IL)-10, a pain resolving cytokine, is produced by resident macrophages in the spinal meninges during remission from pain and signaled to IL-10 receptor-expressing sensory neurons. Using unbiased RNA-sequencing, we identified that IL-10 upregulated expression and antinociceptive activity of δ-opioid receptor (δOR) in the dorsal root ganglion. Genetic or pharmacological …
