View in BioMuta


ST14 protein is an epithelial-derived, integral membrane serine protease and is found to be activated by sphingosine 1-phosphate. The expression of this protease has been associated with breast, colon, prostate, and ovarian tumors, which implicates its role in cancer invasion, and metastasis.

ST14 localized to vascular-like structures in ovarian cancer but not in normal ovaries.

Performance Comment

ST14 was one of 13 genes out of 50 selected for further validation in PMID:21617380. Average expression of ST14 was significantly higher in epithelial ovarian cancer tumors than any other normal tissue tested.
