Cathepsins are key enzymes in mediating turnover of cytosolic proteins. In the context of cancer progression, those most actively studied include cathepsins D and B which have been implicated in processes such as growth and metastasis of many types of cancer. For more than 10 years, their roles as tumor marker and prognostic indicators have been studied, especially in breast cancer. Most of the studies...
Hemoglobin (Hb) was entrapped in a titania sol-gel matrix and used as a mimetic peroxidase to construct a novel amperometric biosensor for hydrogen peroxide. The Hb entrapped titania sol-gel film was obtained with a vapor deposition method, which simplified the traditional sol-gel process for protein immobilization. The morphologies of both titania sol-gel and the Hb films were characterized using...
