Cathepsin D is a lysosomal aspartic protease of the pepsin family (4). Mouse Cathepsin D is synthesized as a precursor protein, consisting of a signal peptide (residues 1‑20), a propeptide (residues 21‑64), and a mature chain (residues 65‑410) (1‑3). It is expressed in most cells and overexpressed in breast cancer cells (5). It is a major enzyme in protein degradation in lysosomes, and also involved in the presentation of antigenic peptides. Mice deficient in this enzyme showed a progressive atrophy of the intestinal mucosa, a massive destruction of lymphoid organs, and a profound neuronal ceroid lipofucinosis, indicating that Cathepsin D is essential for proteolysis of proteins regulating cell growth and tissue homeostasis (6). Cathepsin D secreted from human prostate carcinoma cells is responsible for the generation of angiostatin, a potent endogeneous inhibitor of angiogenesis (6).

Detection of Mouse Cathepsin D by Western Blot
VEGF replenishment reverses defective autophagy in NP–C mice.(a) Western blot analysis of LC3, beclin-1, p62 and cathepsin D in primary cultured PNs derived from WT, NP–C and VEGF/NP–C mice (WT, n=5; NP–C, n=6; and VEGF/NP–C, n=6). (b) Immunocytochemistry of LC3 in WT, NP–C and VEGF/NP–C PNs (n=6 per group; scale bar, 20 μm). (c) Cathepsin D activity in primary cultured PNs (WT, n=5; NP–C, n=6; and VEGF/NP–C, n=6). (d) Western blot analysis of LC3, beclin-1, p62 and cathepsin D in the cerebellums of 6-week-old WT, NP–C and VEGF/NP–C mice (WT, n=6; NP–C, n=7; and VEGF/NP–C, n=7). (e) Cathepsin D activity in the cerebellums of WT, NP–C and VEGF/NP–C mice (WT, n=5; NP–C, n=6; and VEGF/NP–C, n=6). (f) EM images and quantification data of the cerebellum (n=5 per group; low-magnification scale bar, 1 μm; high-magnification scale bar, 200 nm). Arrow indicates autophagic vacuole. (g) Western blot analysis of Rab5 and Rab7 levels in the cerebellum (n=6 per group). (h) Cerebellar sections were immunostained with anti-active caspase-3 and the number of active caspase-3-positive cells in PCL was quantified (n=5 per group; scale bar, 50 μm). a–g, one-way analysis of variance, Tukey’s post hoc test. h, Student’s t-test. *P<0.05, **P<0.01, ***P<0.005.
