Selective Activation Of Thrombin Activatable Fibrinolysis Inhibitor (Tafi) Attenuates Metastatic And Angiogenic Capabilities Of Melanoma And Lung Carcinoma In Vitro, Jacklyn Krizsan

Electronic Thesis and Dissertation Repository

Metastasis and angiogenesis are hallmarks of aggressive cancers, both depending on degradation of extracellular matrix by proteases such as plasmin. Plasmin activation is inhibited by thrombin-activatable fibrinolysis inhibitor (TAFI)-mediated cleavage of terminal lysine residues on plasminogen receptors. Activation of TAFI is most effectively done in complex with thrombomodulin (TM). TM is known to have anti-cancer properties, but it is not known if this is due to TAFI activation or an alternative substrate protein C (PC). We hypothesize that specific promotion of TAFI activation with TM treatment will attenuate metastatic and angiogenic capabilities of tumour cells.

The Role Of Myocardin In The Progression Of Non-Small Cell Lung Cancer, Soromidayo Akinsiku

Biotechnology Theses

Lung cancer is the leading cause of cancer-related mortality in the world and NSCLC accounts for 85% of all lung cancer cases. The mainstay of treatment for patients with stage I, II and IIIA NSCLC is surgery, followed by post-operative cisplatin-based chemotherapy. Additional adjuvant therapy involving targeted tyrosine kinase inhibitors has been in use, however even for the targeted therapy, resistance eventually develops. Therefore, there is a need for identifying novel targets for this life-threatening disease. Given that preliminary studies in Ikebe lab revealed that myocardin knockdown significantly promoted caspase-3 degradation, in this study, using myocardin siRNA, we investigated the …
