TIMP1 and breast carcinoma: The antiapoptotic effect of TIMP-1 induced by various apoptotic agents has been demonstrated in several different cell types such as human breast epithelial cells (Li et al, 1999; Liu et al, 2003, 2005), human breast carcinoma cells (Lee et al, 2003), human endothelial cells (Boulday et al, 2004), hepatic stellate cells (Murphy et al, 2002, 2004) and Burkitt's lymphoma cells (Guedez et al, 1998).
