Abstract:
Integrin alpha v-beta 3 is involved in tumor angiogenesis while the clinical significance of beta 3 integrin expression in colorectal cancer and lung metastases. Analysis was performed on 51 colorectal cancer patients (22 with subsequent lung metastasis and 29 without lung metastasis). Fifty-one primary tumors and 22 lung metastases were examined for immunohistochemical detection of integrin beta 3. We found that the antibody VNR 5 to integrin beta 3 prefentially stains the blood vessels of small caliber. Indeed, vascular integrin beta 3 index was significantly higher in tumors of patients with lung metastasis than in those without lung metastasis. In the patients with lung metastases, vascular integrin beta 3 index was significantly lower in lung metastases than in primary tumors. It was immunohistochemically proved that integrin beta 3 is an important vascular endothelial cell market for lung metastasis.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Integrins
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...
Activation of Integrins
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding events provide an effective stimulus.
