Description générale
Research area: Cell Signaling
Cathepsin D is a soluble endosomal-lysosomal aspartic protease and is synthesized in the rough endoplasmic reticulum as preprocathepsin D. It is encoded by the CTSD gene located in the 11p15.5 region.

Application
Cathepsin D from bovine spleen has been used:
- in in vitro dose-dependent fluorometric activity assays.
- in in vitro myelin oligodendrocyte glycoprotein (MOG) digestion to study the uptake of malondialdehyde (MDA)-modified MOG and its implications in central nervous system autoimmunity.
- for enzymatic digestion of the proteoglycan moiety of the articular cartilage in order to determine its dynamic elastic modulus at two different levels of tissue organization.
- in cathepsin D activity assay.
Actions biochimiques/physiologiques
Cathepsin D is an endosomal-lysosomal aspartic protease implicated in breast cancer metastasis and Alzheimer′s disease. Lysosomal release of cathepsin D has been found to precede cytochrome c release and loss of membrane potential in apoptotic human foreskin fibroblasts. Cathepsin D levels in PC12 cells increase 12 to 24 hours after apoptosis is induced.

The small molecule b-AP15 is a novel inhibitor of proteasome deubiquitination. Recent studies have shown that b-AP15 displays antitumor activity in several preclinical, solid tumor models. In this study, we show that b-AP15 triggers time- and dose-dependent apoptosis of the

The proinflammatory cytokine IL-1β is a key mediator of inflammatory responses that contribute to and exacerbate brain injury. IL-1β is synthesized by microglia in the brain as an inactive precursor (pro-IL-1β). Cleavage of pro-IL-1β to a mature form is stimulated

Lysosomal enzymes function optimally in acidic environments, and elevation of lysosomal pH can impede their ability to degrade material delivered to lysosomes through autophagy or phagocytosis. We hypothesize that abnormal lysosomal pH is a key aspect in diseases of accumulation
