Background

Maspin is a unique member of the serpin family that shares extensive homology with monocyte-neutrophil elastase inhibitor, PAI-2 and other serpins. Maspin has been shown to inhibit invasion and motility of mammary tumors. Tumor transfectants expressing maspin exhibit decreased growth and metastasis in nude mice. Maspin gene expression is not detected in most breast tumors and loss of its expression is correlated with tumor invasiveness. Maspin is also found to be a potent angiogenesis inhibitor. In human breast tissue, maspin seems to be present more in luminal than myoepithelial cells, and it has been suggested that those maspin-expressing myoepithelial cells form a defensive barrier for the progression from ductal carcinoma in situ to more invasive carcinomas. A dispute exists regarding whether maspin acts as a protease inhibitor among biochemists[1].
