Angiogenesis is of vital importance during the development and progression of solid tumors. To examine the role of vascular endothelial growth factor (VEGF) in hepatocarcinogenesis, we evaluated the expression of peptide in normal human liver (n = 6) and in 36 cases of hepatocellular carcinoma (HCC). Immunoreactivity for VEGF was present in the extracellular matrix of the portal tracts in the normal...
The interaction between tumor cells and laminin mediated by laminin-binding integrins is critical for tumor invasion and metastasis. The aim of this study was to clarify the altered expression of lamininbinding integrins with the change of laniinin deposition in hepatocellular carcinoma (HCC) in comparison with cirrhotic or normal liver by immunohistochemistry. In HCC, hepatoma cells and sinusoidal...
