However, since these cell lines did not show a fully malignant phenotype, we concluded that, in addition to the degradation of extracellular matrix macromolecules, including basement membrane components by MMP-2, -3, and/or -9, some additional factors must be involved for the malignancy of fully transformed cells and that these immortalized human aortic SMC, which share many characteristics with normal SMC, will prove useful to study the role(s) of metalloproteinases in atherosclerosis.

Our study demonstrates that of all tested components of the matrix metalloproteinase system, only expression of activated MMP-2 correlates with increased malignancy in our melanoma xenograft model, corroborating an important role of MMP-2 in human melanoma invasion and metastasis.

A high level of the active form of MMP-2 in almost all of the carcinomas and the near lack of its activation in normal lung parenchyma shows that MMP-2 activation is associated with the malignant phenotype and may serve as a good marker of malignancy.

Ras expression has been suggested as a marker for tumor aggressiveness of breast cancer,including the degrees of invasion and tumor recurrence.We showed previously that H-ras, but not N-ras, up-regulates matrix metalloproteinase 2 expression and induces invasive phenotype in MCF10A human breast epithelial cells (A.Moon, et al.Int.J.Cancer, 85: 176-181, 2000).

The gene expression or activation of matrix metalloproteinase-2 (MMP-2), vascular endothelial growth factor (VEGF) and the p42/p44 mitogen-activated protein kinase (MAPK, ERK) that correlated with endothelial cells growth, migration and angiogenesis were also induced by saikosaponin C. From these results, we suggest that saikosaponin C may have the potential for therapeutic angiogenesis but is not suitable for cancer therapy.
