PEDF (Serpin F1)

Biological or Clinical Significance:

Pigment epithelium-derived factor (PEDF) also known as serpin F1 (SERPINF1), is a multifunctional secreted protein that has anti-angiogenic, anti-tumorigenic, and neurotrophic functions. Found in vertebrates, this 50 kDa protein is being researched as a therapeutic candidate for treatment of such conditions as choroidal neovascularization, heart disease, and cancer. In humans, pigment epithelium-derived factor is encoded by the SERPINF1 gene.

PEDF, a protein with many functions, has been suggested to play a clinical role in choroidal neovascularization, cardiovascular disease, diabetes, diabetic macular edema, osteogenesis imperfecta and cancer. As an antiangiogenic protein, PEDF may help suppress unwanted neovascularization of the eye. Molecules that shift the balance towards PEDF and away from VEGF may prove useful tools in both choroidal neovascularization and preventing cancer metastasis formation.
