Appropriate Preconditioning Of The Uterine Endoplasmic Reticulum Stress Response Inhibits Preterm Labor, Judith Ann Ingles
Appropriate Preconditioning Of The Uterine Endoplasmic Reticulum Stress Response Inhibits Preterm Labor, Judith Ann Ingles
Wayne State University Dissertations
Introduction: In this study, we are testing the overarching hypothesis that preconditioning the myometrial UPR allows for the maintenance of non-apoptotic CASP3 activity and thus sustains uterine quiescence. We have previously demonstrated that the pregnant uterus facilitates uterine quiescence through UPR mediated activation of non-apoptotic CASP3, yet the mechanism in which CASP3 utilizes to avoid its apoptotic cell fate is unresolved. There is a growing body of evidence including our own that demonstrates remote and direct preconditioning with minor stresses propagates cytoprotective mechanisms that allow for the avoidance of apoptotic cell death upon exposure to a subsequent more damaging stress, …
Identifying The Role Of The Type-Ii Transmembrane Serine Protease Tmprss13 In Breast Cancer, Andrew Stevan Murray
Identifying The Role Of The Type-Ii Transmembrane Serine Protease Tmprss13 In Breast Cancer, Andrew Stevan Murray
Wayne State University Dissertations
Breast cancer is the most frequently diagnosed cancer and the second leading cause of cancer death in women in the United States. Breast cancer progression is accompanied by increased expression of extracellular and cell surface proteases that are capable of degrading the extracellular matrix as well as cleaving and activating downstream targets. These proteolytic processes are critically involved in modifying the tissue microenvironment of the breast, which is necessary for cancer cell invasion and eventual dissemination of cancer cells to other organs. Therefore, identifying novel proteases that promote tumor progression is critical to create new approaches for developing improved breast …

Metabolic reprogramming and redox control of cancer cells is vital for their proliferation, but also provides selective strategies for treating cancer. Increased generation of reactive oxygen species (ROS) and an intricate control of redox status in cancer cells relative to normal cells provide a basis for designing ROS-inducing anticancer agents. In my work, I designed, synthesized and evaluated carbohydrate-based small molecules for ROS-generation, cytotoxicity and redox signaling and stress response. Our data …
The Mechanism Responsible For Mechanically Enhanced Cancer Cell Invasion, Alexander Nicholas Gasparski
The Mechanism Responsible For Mechanically Enhanced Cancer Cell Invasion, Alexander Nicholas Gasparski
Wayne State University Dissertations
Cell invasion is an important process utilized by cancer cells to progress through the metastatic cascade to form deadly secondary tumors. This process can be influenced by the wide array of biomechanical forces that cancer cells within and around a tumor face in their microenvironment. It is not completely clear how these forces, either alone or simultaneously combined with other forces, can impact the metastatic capacity of cancer cells. To address this, we have utilized an in vitro mechano-invasion assay to mimic a transient tugging force that exists within the tumor microenvironment caused by the remodeling of the extracellular matrix …
