| Outline of Final Research Achievements |
We analyzed the relation between phenotypic transition of tumor cells and ectodomain shedding activity of membrane-anchored growth factor proHB-EGF in breast tumor MCF-7 cells. We established two MCF-7 clones and further analyzed. One (clone #8) mostly generated epithelial-like colonies, while the other (clone #5) produced both epithelial- and fibroblast-like colonies. We demonstrated that proHB-EGF was more shed in breast tumor MCF-7 cells with epithelial-like morphology than those with fibroblast-like morphology. We speculate that ectodomain shedding of proHB-EGF could be associated with morphological phenotype transition of breast tumor cells.
