KLK-10 (also known as kallikrein-related peptidase 10) is primarily studied in the context of cancer diagnostics and biomarker research. It has shown potential as a biomarker for certain types of cancers, particularly ovarian, breast, and lung cancers, due to its elevated levels in patient serum or tissue samples. Its expression is often correlated with disease progression and prognosis, making it useful in clinical monitoring. Research is ongoing into its role in cell growth regulation and tissue remodeling, which may lead to targeted therapeutic applications. Additionally, KLK-10 is being explored for use in immunoassay development for early cancer detection.
