Description…

SLPI is a secreted inhibitor which protects epithelial tissues from serine proteases. It is found in various secretions including seminal plasma, cervical mucus, and bronchial secretions, and has affinity for trypsin, leukocyte elastase, and cathepsin G. Its inhibitory effect contributes to the immune response by protecting epithelial surfaces from attack by endogenous proteolytic enzymes; the protein is also thought to have broad-spectrum anti-biotic activity.

Organs

The following organs have data associated with this biomarker…

Ovary

Attributes

Phase: Three
QA State: Curated

Overview

Overexpression of SLPI has been measured in invasive and low malignant potential tumors compared with benign and normal tissues.

Performance Comment

Of the 28 ovarian cancer biomarkers tested in prediagnostic specimens, from the PLCO, CA125 remains the single best biomarker for ovarian cancer and has its strongest signal within six months of diagnosis. SLPI alone was not a strong predictor.

Prostate
