23224034 KLK7 and KLK14 gene expression can be regarded as markers of poor prognosis for colorectal cancer patients with discriminating power between CC and adenoma patients.
22505524 KLK8 and KLK14 can signal differentially via the PARs to affect tissue function
22505523 KLK14, acting via PAR-2, represents an autocrine/paracrine regulator of colon tumorigenesis
22505522 genetic variants in the KLK14 locus are associated with risk and/or aggressiveness of prostate cancer
21057706 KLK14 gene expression could be evaluated as a putative independent diagnostic biomarker in breast tumour biopsies.
20424135 Observational study of gene-disease association. (HuGE Navigator)
20155713 The differences in the levels of KLK14 suggest that KLKs may aid in the differential diagnosis of salivary gland tumors. The coexpression of KLKs suggests their possible involvement in an enzymatic pathway activated in salivary gland.
19558318 Combination of KLK2, 3, 13, and 14 and KLK1, 2, 5, 6, 7, 8, 10, 13, and 14 showed very strong discriminatory potential for semen liquefaction and viscosity, respectively.
19383315 synergistic effects between estrogens and androgens on estrogen-sensitive genes may have implications on the role of the kallikreins 10, 11, and 14 in associated risk of breast cancer and progression.
19147544 KLK4 is only expressed in breast and prostate cancers that express the progesterone receptor (PR) and androgen receptor (AR), respectively.
18627302 positive staining was significantly associated with NSCLC adenocarcinoma histotype (KLK13, p=0.014) and tumor size (KLK14, p=0.048)
18497543 Expression of the KLK14 protein correlated with the pathological tumor status in prostate cancer and was associated with disease progression defined by prostate-specific antigen relapse in univariate Kaplan-Meier analysis.
18482984 semenogelins I and II were directly cleaved by KLK14. Semenogelins were also able to reverse KLK14 inhibition by Zn2+, providing a novel regulatory mechanism for KLK14 activity.
18056261 KLK14 is a new activator component of the KLK proteolytic cascade with a possible role in seminal plasma and skin
17625593 KLK5 and KLK14, but neither KLK7 nor KLK8, induced PAR2 signalling.
17158887 KLK14 may participate in epidermal desquamation through cleavage of desmoglein 1 and regulation by lympho-epithelial Kazal-type-related inhibitor (LEKTI).
17110383 KLK14 may be implicated in several facets of tumor progression, including growth, invasion, and angiogenesis, as well as in arthritic disease via deterioration of cartilage
16800737 The majority of KLK14 in the plantar stratum corneum is present in its catalytically active form. KLK14 could be immunohistochemically detected in sweat ducts, preferentially in the intraepidermal parts (the acrosyringium), and in sweat glands.
16434994 KLK14 is clearly overexpressed in breast cancer in comparison to normal breast tissues and is positively associated with conventional parameters of tumour aggressiveness
15843175 hK14 has dual activity, trypsin- and chymotrypsin-like, with a preference for cleavage after arginine residues
15654974 may be part of a protease cascade in the stratum corneum, and that the observed pH effects may have physiological relevance.
12858357 KLK14 expression upregulated in advanced and more aggressive prostate tumors; may play role in tumor spread and may be new marker for prostate cancer diagnosis and prognosis
12439719 KLK14 overexpression was found to be a significant predictor of decreased disease-free survival and overall survival in breast cancer patients
