Epidermal growth factor (EGF) is a potent stimulus of migration in several breast cancer cell lines [19], however depletion of MYOF in MDA-MB-231 and MDA-MB-468 cells blocked EGF- stimulated migration and EMT and reduced tumor development in a chicken chorioallantoic membrane xenograft model of human breast cancer [8]. The gene discussed is MYOF; the disease is breast cancer.
