Investigation Of Avaren-Fc's Therapeutic Potential Against Ovarian Cancer., Katarina Lee Mayer May 2024

Investigation Of Avaren-Fc's Therapeutic Potential Against Ovarian Cancer., Katarina Lee Mayer

Electronic Theses and Dissertations

This thesis describes the investigation of Avaren-Fc (AvFc), a novel lectin-based therapeutic fusion protein consisting of the recombinant Avaren lectin and the Fc region of human IgG1, against ovarian cancer. AvFc possesses selectivity toward tumor associated N-linked high-mannose-type glycans. The present study demonstrates AvFc’s in vitro activity against OVCA cell lines via antibody-dependent cell-mediated cytotoxicity and its ability to extend the survival of mice challenged with murine ID8 OVCA cells after repeated systemic administration. Furthermore, AvFc treatment in this model was found to increase the presence of peritoneal leukocytes, suggesting a shift toward an improved antitumor immune response. Another key …


Development Of A Lectin-Fc Fusion Protein With Antiviral And Anti-Cancer Activity., Matthew William Dent May 2019

Development Of A Lectin-Fc Fusion Protein With Antiviral And Anti-Cancer Activity., Matthew William Dent

Electronic Theses and Dissertations

This thesis describes the development of a novel lectin-Fc fusion protein and its antiviral and anti-cancer activity. The molecule, Avaren-Fc (AvFc), is a fusion of a variant of the actinomycete lectin actinohivin (Avaren) and the Fc region of human IgG1, and is selective for the terminal α1,2-mannose residues found at the ends of high-mannose-type glycans that can be found on the surface of certain heavily glycosylated viruses and cancer cells. Here, AvFc was found to be able to neutralize simian immunodeficiency virus as well as Hepatitis C virus with nanomolar IC50 values. Furthermore, AvFc recognizes a number of cell …
