In agreement with the aforementioned significance of KLK5 for the ovarian cancer patients' prognosis, higher KLK5 gene transcriptional levels were detected in patients with aggressive forms of epithelial ovarian tumors [16], while the differential profile of the expressed KLK5 mRNA transcript variants between normal and malignant ovarian cancer cells was uncovered [17]. The gene discussed is KLK5; the disease is ovarian carcinoma.
