Anti-Cancer Activity Of Marine-Derived Fucosylated Chondroitin Sulfates In Ovarian Cancer Cell Spheroid Formation And Notch Signaling Inhibition, Daniella Beiner

Honors Theses

Ovarian cancer is the deadliest gynecological malignancy, with high recurrence rates driven by chemotherapy-resistant cancer stem cells (CSCs). Current therapeutics targeting Notch signaling to inhibit CSC formation have yet to demonstrate clinical benefit and pose risk of gastrointestinal toxicities. Here, we report that treatment with fucosylated chondroitin sulfates (FucCS) inhibited Notch signaling activation and spheroid formation in OVCAR3 ovarian cancer cells. Sulfation and fucosylation were shown to be key structural requirements of this anti-cancer activity. Moreover, this inhibition was synergistic with suppression of Notch glycosylation by Radical Fringe knockout. Preliminary experiments to conjugate FucCS to a maleimide linker in preparation …
