The Role Of Nitric Oxide Dysregulation In Tumor Maintenance, Christopher Rabender
The Role Of Nitric Oxide Dysregulation In Tumor Maintenance, Christopher Rabender
Theses and Dissertations
The inflammatory nature of the tumor microenvironment provides a cytokine and chemokine rich proliferative environment. Much of the responsibility of this environment is due to the production of Reactive Oxygen Species (ROS). These studies examined the proliferative rich tumor environment from a new perspective of Nitric Oxide Synthase (NOS) dysregulation. NOS’s have the ability to become uncoupled and generate superoxide in lieu of nitric oxide (NO). A requirement of NOS for the production of NO is the cofactor tetrahydrobiopterin (BH4) and when it is missing NOS becomes uncoupled and turns into a peroxynitrite synthase. Here I demonstrate that NOS is …
Use Of Biophotonic Models To Monitor Biological Compounds Via The Angiogenic System, Ramey C. Youngblood
Use Of Biophotonic Models To Monitor Biological Compounds Via The Angiogenic System, Ramey C. Youngblood
Theses and Dissertations
Angiogenesis is a central process to both physiological and pathological aspects of living organisms. Understanding the angiogenic system via the key mediator, vascular endothelial growth factor (VEGF), has led to the development of biophotonic models capable of monitoring how this process is programmed. The whole animal model tested here is based on the involvement of angiogenesis in a wound healing environment. This model proved to be functional as a system monitor but lacked the precision to yield significant results between the biological compounds tested (estrogen, methoxychlor, and relaxin). The in vitro model is based on angiogenesis in a cancer environment. …
The Role Of Family Organization In Family Health History Communication About Cancer, Vivian M. Rodríguez
The Role Of Family Organization In Family Health History Communication About Cancer, Vivian M. Rodríguez
Theses and Dissertations
Family health history (FHH) has been recognized as an important tool in cancer prevention and health promotion. To date, literature on FHH discussions about cancer have largely focused on patient-physician communication or the dissemination of cancer-specific genetic tests results within the family. Fewer studies have sought to identify family factors that may promote FHH discussions, yet this type of information could be used to identify families needing support in having these conversations. Thus, the present study examined relations between family organization (cohesion and flexibility), communication openness, and FHH communication about cancer within a diverse group of women recruited from an …
The Effect Of Thymidylate Synthase Inhibitors On Bone Marrow Derived Cells In The Intestinal Tumor Microenvironment, Grishma Acharya
The Effect Of Thymidylate Synthase Inhibitors On Bone Marrow Derived Cells In The Intestinal Tumor Microenvironment, Grishma Acharya
Theses and Dissertations
Tumors have come to be known as independently functioning complex organs consisting of cancer cells coexisting with a heterogeneous mixture of host-derived non-neoplastic cells that form the tumor stroma. Tumor survival, progression, and metastasis depend on multiple close interactions between the cancer cells and the tumor stromal cells. These tumor stromal cells are mainly bone marrow derived cells (BMDCs) that are recruited to the primary tumor and sites of metastasis by a variety of signals secreted by the cancer cells. Because of the close interaction between the tumor and the tumor stroma, we propose that tumor stromal cells play an …
