Angiogenesis is crucial for the growth and metastasis of solid tumors with sizes larger than a few cubic millimeter Canstatin, the non-collagenous 1 (NC1) domain of alpha2 chain of type IV collagen, was previously shown to inhibit proliferation of endothelial cells in vitro and suppress in vivo tumor growth. Our previous studies showed that canstatin-N, the(More)
Type IV collagen is one of the components of vascular basement involved in regulation of angiogenesis. Canstatin, the non-collagenous 1 (NC1) domain of alpha2 chain of type IV collagen, was identified as an inhibitor of angiogenesis and tumor growth by Kamphaus et al. Our previous studies showed that canstatin-N, the N-terminal 1-89 amino acid fragment of(More)
Human CC chemokine receptor (CCR) 5 is a G protein-coupled receptor involved in a broad range of human diseases that mediates HIV-1 viral entry into cells. Certain small molecule receptor antagonists to CCR5 have been useful in therapy for these diseases. In this study, CCR5-expressing CHO cells (CHO/CCR5 cells) were used to select CCR5-binding peptides(More)
Endostatin, a 20-kDa carboxyl-terminal fragment of collagen XVIII, is a potent inhibitor of endothelial cell proliferation and tumor angiogenesis. We have constructed replication-deficient recombinant adenovirus (Ad-rhE), which encoded secreted human endostatin, and our previous studies showed that Ad-rhE had a potent suppression of tumor growth in vivo. In(More)
Total RNA was extracted from placenta umbilical tissue. The canstatin cDNA was amplified from total RNA by net-RT-PCR technique and cloned into pSP72, and the resulted plasmid pSP72C was used as template to amplify its N-domain. The amplified 1-89 aa N-domain was then cloned into pET-3c. The resulted plasmid pET-CN was transformed into E. coli BL21(DE3).(More)
