“…5). In addition, PSA-activated prodrugs have been designed for treatment of prostate cancer based on the fact that serum PSA is mostly enzymatically inactive, whereas in the prostate gland, it is found in its active form (6). Notably, administration of recombinant KLK6 to mice with EAE resulted in the production of anti-KLK6 antibodies that inhibited its enzymatic activity, attenuated the severity of symptoms, and delayed the course of disease progression (7).…”
Kallikrein-related peptidases constitute a single family of 15 (chymo)trypsin-like proteases (KLK1-15) with pleiotropic physiological roles. Aberrant regulation of KLKs has been associated with diverse diseases such as hypertension, renal dysfunction, skin disorders, inflammation, neurodegeneration, and cancer. Recent studies suggested that coordinated activation and regulation of KLK activity are achieved via a complex network of interactions referred to as the "KLK activome." However, it remains to be validated whether these hypothetical KLK activation cascade pathways are operative in vivo. In addition, KLKs have emerged as versatile signaling molecules. In summary, KLKs represent attractive biomarkers for clinical applications and potential therapeutic targets for common human pathologies.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
