Insulin-like growth factor binding proteins initiate cell death and extracellular matrix remodeling in the mammary gland [PDF]

open access: yes, 2005
We have demonstrated that insulin-like growth factor binding protein-5 (IGFBP-5) production by mammary epithelial cells increases dramatically during forced involution of the mammary gland in rats, mice and pigs.
