  • It was the first angiogenic protein to be isolated from conditioned medium of human tumour cells, being characterised by its capacity to induce neovascularization [3]. (angiogenesis-blog.com)
  • The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth, and motility. (wikipedia.org)
  • As pancreatic ribonuclease is unable to induce angiogenesis, this structural similarity has served to study angiogenins structure/function relationships relative to bovine pancreatic ribonuclease (RNase A). An intact catalytic site and cell-binding domain are required for angiogenin to induce neovascularization ([10], for review). (angiogenesis-blog.com)
  • Antibody induced internalisation was reduced in C-terminal deletion mutants and abolished in G→A and Y→A mutants, showing the crucial role of these residues in internalisation. (wikipedia.org)

  • In this study, the relationship between the expression of PMN degranulation markers (CD63 and CD66b) and the release of degranulation products [myeloperoxidase (MPO) and lactoferrin (LF)] was investigated during clinical HD in order to evaluate cell surface markers as a useful index of PMN degranulation.
