Scientific Data Images for Mouse Cathepsin B Antibody

Cathepsin B antibody in Mouse Thymus by Immunohistochemistry (IHC-Fr).

Cathepsin B in Mouse Thymus.

Cathepsin B was detected in perfusion fixed frozen sections of mouse thymus using 5 µg/mL Goat Anti-Mouse Cathepsin B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF965) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Mouse Cathepsin B by Immunocytochemistry/ Immunofluorescence

Detection of Mouse Cathepsin B by Immunocytochemistry/ Immunofluorescence

EMT in BSA-induced damaged tubule was associated with increased levels of DPP-4, integrin beta1 and CAV1; TENE treatment ameliorated these alterations. (a–e) Multiplex immunofluorescence microscopy analysis of the EMT program and association with CAV1. Formaldehyde-fixed, paraffin-embedded (FFPE) kidney samples were labeled with epithelial markers for E-cadherin, alphaSMA and CAV1. An immunofluorescence analysis was performed by confocal microscopy. (d) The enlarged image of the inset shown in (c). The alphaSMA-positive damaged tubular cells were surrounded by alphaSMA-positive interstitial cells (f–j). Multiplex immunofluorescence was performed to analyze the crosstalk among DPP-4, integrin beta1 and CAV1 in the BSA-injected diabetic mice. (i) The enlarged image of the inset shown in (h). DPP-4, integrin beta1, and CAV1 were localized at the same location (likely the luminal side of the proximal tubule). The crosstalk occurred more frequently in the damaged tubular cells. Representative images from n = 7 in each group are shown.

BSA-injected diabetic mice exhibited high tubular levels of DPP-4, CAV1 and EMT program; TENE treatment ameliorated these alterations. Immunohistochemical analysis of (a–d) DPP-4, (e–h) CAV1, (i–l) snail and (m–p) AQP-1 from the BSA-injected control or diabetic mice with or without the TENE treatment. Scale bar, 50 μm. Representative images from n = 7 in each group are shown. Each group was analyzed with an unpaired two-tailed t-test. *P < 0.05, **P < 0.01. Data are presented as mean ± s.e.m (q–t).

Background: Cathepsin B

Cathepsin B is the first described member of the family of lysosomal cysteine proteases (1). Cathepsin B possesses both endopeptidase and exopeptidase activities, in the latter case acting as a peptidyl-dipeptidase. It is known to process a number of proteins, including pro and active caspases, prorenin and secretory leucoprotease inhibitor (SLPI) (2‑4). Therefore, Cathepsin B may play a role in activation and inactivation of caspases, activation of renin and inactivation of SLPI, the key steps in apoptosis, angiotensin production, and progression of emphysema, respectively. Because of its increased levels and redistribution in human and animal tumors, Cathepsin B may also have a role in invasion and metastasis (5). In addition to the lysosome, Cathepsin B can be secreted or associated with plasma membrane, cytoplasm, and nucleus. It is synthesized as a preproenzyme. Following removal of the signal peptide, the inactive proenzyme undergoes further modifications including removal of the pro region to result in the active enzyme (5).
