SERPINF1 and neoplasm: In this regard, the 34-mer and a shorter peptide within the 34-mer (an 18-mer, Asn60-Asn77) were investigated for the anti-angiogenic activity of PEDF, including induction of endothelial cell apoptosis, blockage of VEGF-induced neovessel formation, analyzed by a mouse corneal pocket assay, and reduction of vascular density in tumor tissues [4, 6].
