| Outline of Final Research Achievements |
We explored the mechanisms of resistance to anti-VEGF therapy in ovarian cancer. In mouse models, anti-VEGF-antibody-resistant tumor showed larger hypoxic area and higher expression levels of GM-CSF. GM-CSF enhanced the production and immune-suppressive property of Myeloid Derived Suppressor Cells (MDSC) from myeloid cells. Our data indicated that targeting the hypoxia-induced cytokine, GM-CSF, may overcome the resistance to antiangiogenic therapy in ovarian cancer.
