The Differential Expression Of Egfl7 Transcripts During Angiogenesis In Human Fibrosarcoma, Navid Baktash

Electronic Thesis and Dissertation Repository

The growth of a tumor depends on de novo angiogenesis, which involves multiple signaling cascades and is also a target for many anti-angiogenic therapies. Epidermal growth factor like (EGFL7), is a protein that is exclusively expressed by endothelial cells during angiogenesis and is necessary for the proper assembly of a sprout. However, EGFL7 is also upregulated in many tumors such as glioma and non-small cell lung cancer, associated with poor patient prognosis. We have previously shown that EGFL7 expression by tumor cells inhibits tumor angiogenesis, which is contrary to its requirement for angiogenesis when expressed by endothelial cells. As a …
