26231762 Data demonstrate that elevated levels of KLK6, KLK7 and KLK9 proteins are associated with poor glioblastoma patients survival.
26032414 Proteolytic cleavage of midkine, CYR61, and tenascin-C govern the pathophysiological roles of KLK7.
26022646 This report demonstrates that concurrent loss of KLK5 and KLK7 associates with a poor clinical outcome in Squamous-Cell Carcinoma and could therefore serve as prognostic marker in this disease.
25477184 KLK6 and KLK7 mRNA and protein overexpression is directly associated with early-stage ovarian tumors.
25448018 Daata indicate that the peptide Abz-NLY( downward arrow)RVE-Q-EDDnp is the best synthetic substrate for Kallikrein-related peptidase 7 (KLK7) [kcat/Km=455 (mMs)(-1)].
25182706 Our findings suggest that serum KLK7 may be a valuable diagnostic biomarker for cervical cancer, and may help to determine the individual prognosis of these patients.
25153388 These results demonstrate the aberrant expression of KLK7 in colon cancer cells and tissues and its involvement in cell proliferation in vitro and in vivo.
23495698 Prochemerin processing protease converts prochemerin into active chemerinF; the activating truncation by the protease may trigger a structural C-terminal rearrangement leading to increased affinity of chemerin to chemokine-like receptor (CMKLR)1.
23413953 Early-stage oral squamous cell carcinoma and high KLK7 mRNA levels were correlated with the rs10581213(wt/ins + ins/ins) genotypes
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.
