Characterization Of Higher Order Chromatin Structures And Chromatin States In Cell Models Of Human Herpesvirus Infection, Michael Mariani
Characterization Of Higher Order Chromatin Structures And Chromatin States In Cell Models Of Human Herpesvirus Infection, Michael Mariani
Graduate College Dissertations and Theses
Human herpesviruses are ubiquitous pathogens worldwide with 90% of the global population infected with one or more Human herpesviruses (HHV’s) by adulthood. All herpesviruses have three unique life cycle stages. Upon resolution of a primary acute stage infection, they can establish a latent stage infection within the host cell nucleus. This stage is characterized primarily by transcriptional quiescence of the viral genome. Specific physiological conditions (e.g., cell stress) can cause the latent virus to enter the reactivation stage, often many years after resolution of the acute infection, in which the virus becomes replicationally active again. HHV’s are known to cause …
Transcriptional Programming By Thyroid Hormone Receptor Beta Maintains Normal Cell Identity And Suppresses Tumor Growth, Noelle Elizabeth Gillis
Transcriptional Programming By Thyroid Hormone Receptor Beta Maintains Normal Cell Identity And Suppresses Tumor Growth, Noelle Elizabeth Gillis
Graduate College Dissertations and Theses
The overall incidence of thyroid cancer has more than tripled over the past several decades, as has aggressive disease and mortality. The direct relationship between thyroid disease, thyroid hormone levels, and development of thyroid cancer is incomplete. Recent meta-analyses have indicated a higher risk of thyroid cancer for patients with thyroid diseases that reflect an altered thyroid-pituitary signaling axis, which can have profound impacts on the physiology of the thyroid gland. These largely unanswered questions regarding altered thyroid hormone signaling and its consequences for thyroid tumor growth present a significant clinical challenge. This dilemma may come from a lack of …
