- Specialized
:
cathepsina
- Then the researchers developed a model that used patient-varying kinase signals collected from the macrophages or osteoclasts to predict patient-specific activity of four cathepsins: K, L, S, and V.
- cathepsin B
- enzyme called cathepsin
Examples
-
Predictability for all cathepsins ranged from 90 to 95 percent for both macrophages and osteoclasts, despite a range in the level of each cathepsin among the blood samples tested.

According to Platt, the next step will be to assess the model's ability to predict cathepsin activity using blood samples from individuals with the diseases of interest: atherosclerosis, osteoporosis, or cancer.

In a new study, researchers took another step toward that goal by developing a technique able to predict from a blood sample the amount of cathepsins—protein-degrading enzymes known to accelerate these diseases—that a specific person would produce.

The researchers discovered that cathepsin is an enzyme that helps break down proteins in animal cells.
-
In his experiment, he measured the levels of cathepsin to understand its role in protein degradation.
-
The presence of cathepsin in the sample indicated that the proteins were being effectively broken down.

Etymology
Cathepsin comes from a Greek root that means 'to digest'. These enzymes are like the cell's little 'stomach' helpers that break down proteins inside the cell, so the name fits their job.
