  • Experimental Validation Results for Cathepsin D Antibody (YA6245)
    Immunohistochemical analysis of paraffin-embedded human liver tissue using Cathepsin D Antibody (HY-P86553, 1/800). The section was pretreated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked with quick block buffer for 0.5 hours at room temperature, washed with PBS and PBST, and then incubated with the primary antibody overnight at 4℃. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background

  • Function

    Cathepsin D is a lysosomal aspartic protease whose major described function is intracellular catabolism in lysosomal compartments, with additional roles in hormone processing and antigen processing[1]. Its function extends beyond nonspecific acidic bulk degradation, because cathepsin D-deficient mice maintain lysosomal bulk proteolysis but develop intestinal mucosal atrophy, lymphoid-cell destruction, and early death, indicating roles in limited proteolysis and tissue homeostasis[2]. Mechanistically, cathepsin D participates in endocytic and autophagic pathways where lysosomal proteases regulate substrate degradation and cellular remodeling[3]. In apoptosis-related models, mature lysosomal cathepsin D can translocate to the cytosol, and cathepsin D activity has been linked to induced apoptosis[4]. In breast cancer biology, cathepsin D is overexpressed and hypersecreted by epithelial breast cancer cells, correlates with clinical metastasis, and stimulates tumorigenicity, metastasis, cancer-cell proliferation, fibroblast outgrowth, and angiogenesis[4]. Compared with cathepsin E, cathepsin D showed distinct cytosolic activity after lysosomal permeabilization, because cathepsin D silencing prevented stefin B degradation whereas cathepsin E silencing did not[5]. For experimental applications, pepstatin A inhibited aspartic-protease-dependent stefin B degradation, and fluorogenic peptide probes detected cathepsin D activity in macrophages challenged with bacteria[5][6].
