  • kallikrein-related peptidase 6
Serine protease M expressed on epithelial cell surface and released in ECM. Tumor cells treated with a neutralizing KLK6 antibody migrate less than control cells, suggesting a role in invasion and metastasis. Overexpressed in primary breast tumors but not expressed in metastatic tumors.

Organ-Specific Notes

Amplification of a chromosome 19q region with the entire kallikrein family associated with ovarian cancer.

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. KLK6 alone was not a strong predictor.

Supporting Study Data
Intergrated Systems Biology Approach for Ovarian Cancer Biomarker Discovery
Study phase on the ovary: 1

The overall objective is to validate serum protein markers for early diagnosis of ovarian cancer with the ultimate goal being to develop a multiparametric panel consisting of 2-4 novel markers with 10 known markers for phase 3 analysis. In phase 1, we will screen for markers able to pass a threshold of 98% specificity and 30% sensitivity in a cohort of 300 women. Markers that pass phase 1 validation will be investigated in a phase 2 PRoBE cohort with a 98% specificity and 70% sensitivity cut-off. Finally, markers that pass phase 2 validation will be evaluated in EDRN CVC laboratory specimens with a cut-off of > 98% specificity and 90% sensitivity.
