9. Results show that lowering endogenous cathepsin D abundance induced senescence in HeLa cells, leading to reduced cell proliferation, impaired tumorigenesis in a mouse model, and increased permeability of lysosomal membrane and reactive oxygen species accumulation. These results suggest that CTSD is involved in cancer cells in maintaining lysosomal integrity, redox balance, and Nrf2 activity, thus promoting tumorigenesis.

10. Data suggest that, compared to control individuals, serum cathepsin-D levels are up-regulated in patients with T2DM-Y (young onset type 2 diabetes) with and without diabetic retinopathy. This study was conducted in India.

11. apoptosis is accompanied by degradation of the cysteine cathepsin inhibitor stefin B (StfB). CatD did not exhibit a crucial role in this step. However, this degradation was partially prevented through pre-incubation with the antioxidant N-acetyl cysteine

12. The lysosomal enzyme cathepsin D (CTSD) mediates the proteolytic cleavage of PSAP precursor into saposins A-D. Myc-CLN3 colocalized with CTSD and activity of CTSD decreased as myc-CLN3 expression increased, and clearly decreased under hyperosmotic conditions

13. Study demonstrate that PGRN interacts with the lysosomal protease CTSD and maintains its proper activity in vivo. Therefore, by regulating CTSD activity, PGRN may modulate protein homeostasis. This could potentially explain the TDP-43 aggregation observed in frontotemporal lobar degeneration with GRN mutations.

14. The S-nitrosation of a non-catalytic cysteine residue in the lysosomal aspartyl protease cathepsin D (CTSD) inhibited proteolytic activation.

15. Secreted PGRN is incorporated into cells via sortilin or cation-independent mannose 6-phosphate receptor, and facilitated the acidification of lysosomes and degradation of CTSDmat. Moreover, the change of PGRN levels led to a cell-type-specific increase of insoluble TDP-43. In the brain tissue of FTLD-TDP patients with PGRN deficiency, CTSD and phosphorylated TDP-43 accumulated in neurons

16. CTSD, in need of its catalytic activity, may promote proliferation in advanced glycation end products-treated human umbilical vein endothelial cells independent of the autophagy-lysosome pathway.

17. Cathepsin D facilitates the TRAIL-induced apoptosis of MDA-MB-231 breast cancer cells in enzymatic activity-dependent manner. Caspase-8 and Bid proteins are the CD targets. The modulatory role of CD in cell response to TRAIL was also confirmed in another breast cancer cell line SKBR3.

18. Gene expression level of CTSD is significantly higher in AD patients when compared to normal controls.

19. There was a significant difference between groups with and without endothelial dysfunction in terms of cathepsin D levels, and negative and significant correlations were found between brachial artery FMD% and cathepsin D levels. Cathepsin D, which is known to be associated with atherosclerosis, may play a role in the proce

20. Serum CTSB and CTSD concentrations were found to have a diagnostic value in NPC. However, the CTSB and CTSD serum levels had no prognostic role for the outcome in nasopharyngeal carcinoma patients.

Mouse (Murine) Cathepsin D (CTSD) interaction partners

1. Study shows that cathepsin D regulates lipid metabolism in murine steatohepatitis. These data demonstrate for the first time a key regulatory role for cathepsin D in lipid metabolism in the development of non-alcoholic steatohepatitis.

2. Acid ceramidase inhibitor LCL521 targets lysosomes to activate cathepsin B and cathepsin D, resulting in interrupted autophagy and ER stress that culminates in myeloid-suppressor cell death.

3. Study demonstrate that PGRN interacts with the lysosomal protease CTSD and maintains its proper activity in vivo. Therefore, by regulating CTSD activity, PGRN may modulate protein homeostasis. This could potentially explain the TDP-43 aggregation observed in frontotemporal lobar degeneration with GRN mutations.

4. These results suggested that Purkinje cells (PCs) were more vulnerable to CTSD deficiency in lysosomes than to autophagy impairment, and this vulnerability does not depend on the severity of axonal swelling.

5. Exposure of J774A.1 cells to HOCl or HOSCN resulted in a significant decrease in the activity of the Cys-dependent cathepsins B and L, but not the Asp-dependent cathepsin D.
