Insulin and insulin-like growth factors (IGIs) stimulate the growth of human breast cancer cells in vitro. The type I somatomedin receptor (SR) expressed in these cells may mediate the growth effects of these peptides. We have examined the role of this receptor on human breast cancer growth with a monoclonal antibody (alpha-IR-3) that blocks the receptor binding domain and inhibits IGF-I-induced growth. alpha-IR-3 inhibited clonal growth in vitro and blocked the mitogenic effect of exogenous… CONTINUE READING
