The Role Of Kinases Signaling In Organogenesis, Fatemeh Nasehi

All Dissertations

Kinases are crucial regulators of organ development and differentiation. This thesis investi- gates the roles of TAK1, TGFbeta-Activate Kinase 1 (TAK1/Map3K7), and Akt3 kinases in skeletal, cardiac muscle, and cartilage. TAK1 is pivotal for the differentiation of various organ systems, including sinoatrial node and cartilage, and is responsible for phosphorylat- ing a diverse array of downstream kinases. We identified several novel proteins, including phospho-Akts, that are upregulated in response to TAK1 activation. We discovered severe Dilated Cardiomyopathy (DCM) and cartilage defects in Akt3 mutant mice. Although this mouse mutant has been studied for over two decades, we are the first …

Novel Peptide Biomaterials For Enhanced Delivery Of Sirna Cargo For Treatment Of Ovarian Cancer, Timothy Samec

All Dissertations

Ovarian cancer is the 7^th leading cause of cancer related death and the 5^th most commonly diagnosed cancer among women. Primarily diagnosed in stage III or stage IV, aggressive treatment is necessary and involves surgical debulking and administration of systemic chemotherapeutics. Unfortunately, these strategies fall short in effectively treating ovarian cancer and many patients experience local disease recurrence, development of multidrug resistant tumors, regional or distant metastatic events, or a combination of the three. As such, there is a significant need for additional treatment options and methods of delivery to improve therapeutic efficacy and disease survivability.
