Research Abstract

We aimed to elucidate molecular mechanisms of epithelial cell invasiveness and differentiation underlying epithelial cell morphogenesis. Our results are as follows.
1) Mammary epithelial cell replication is not influenced by polyploidy.
2) Activation of MMP-2 by MT1-MMP is required for 3-D invasiveness. Cell surface localization of MT1-MMP was depend on 3-D. MMP-2 expression was strongly correlated to invasiveness and regulated by epigenetics. We identified epigenetic factors and these target genes possibly involved in cancer malignancy.
3) Cell surface Met was heterogeneously expressed in mammary epithelial cells and malignant melanomas. This might reflect invasive and malignant cell phenotypes.
