Breast Ca stained with Anti-Cathepsin D
Cathepsin D is a ubiquitously expressed lysosomal protease that is involved in proteolytic degradation, cell invasion, and apoptosis. It is suspected to play important roles in protein catabolism, antigen processing, degenerative diseases, and cancer progression. Cathepsin D is present in many types of cancer cells. In breast cancer, it is induced by estrogens and its expression is correlated with a higher risk of metastasis and poor disease-free survival. Extensive studies have been also performed to evaluate the clinical and therapeutic implication of Cathepsin D expression in nongynecological solid tumors. Emerging evidence indicates Cathepsin D seems to facilitate early stages of tumor progression such as cell proliferation and local dissemination.
