Yap1 Expression Predicts Sensitivity To Dual Akt/P70s6k Inhibition In Ovarian And Uterine Malignancies, Rebecca A. Previs

Dissertations & Theses (Open Access)

Purpose: The PI3K/AKT/P70S6K pathway is an attractive therapeutic target in ovarian and uterine malignancies due to its high rate of dysregulation and key roles in tumor growth. Here, we examined the biological effects of MSC2363318A, which is a novel inhibitor of AKT1, AKT3, and P70S6K.

Experimental Design: Orthotopic murine models of ovarian and uterine cancer were utilized to study the effect of MSC2363318A on survival and regression. Moreover, in vitro experiments (MTT, Western blot analysis, plasmid transfection, and reverse phase protein array [RPPA]) were carried out to characterize underlying mechanisms and potential biomarkers of response.

Results: MSC2363318A decreased tumor growth …

Src Homology 2 Domain-Containing 5’-Inositol Phosphatase-2 (Ship2) Is An Effector Of Lymphatic Dysfunction, Germaine D. Agollah

Dissertations & Theses (Open Access)

The lymphatic system is essential for the transport of excess fluid, protein, and foreign materials from interstitial tissues to lymph nodes; for immune surveillance, and to maintain fluid homeostasis. Dysregulated lymphatics can be attributed to pathological conditions including tumor metastasis, inflammation, chronic wounds, obesity, blood vascular disorders, and lymphedema. Of these, lymphedema is the most extreme of lymphatic disorders and is represented by a spectrum of symptoms ranging from mild, subtle presentation to severe, disfiguring, overt presentation. Lymphedema is more manageable in the early stages of disease but severely reduces quality of life with progression. Due to lack of molecular …
