KLK7

KLK7

A gene on chromosome 19q13.3 that encodes a serine protease that catalyses the degradation of intercellular cohesive structures in the cornified layer of the skin during the normal shedding of cells from the skin surface. KLK7 may play a role in activating precursors of inflammatory cytokines.

The KLK8 mRNAs were considered alone or as a ratio with the KLK5, KLK6, KLK7, KLK10, KLK11, KLK13, or KLK14 mRNA in the same samples.
The highest concentrations of KLK7 were found in skin (adult and fetal).
KLK7 was found at highest concentrations in CVF, with lower concentrations in breast milk, seminal plasma, breast cancer cytosol, ascites, and saliva.
Three independent groups have found KLK7 mRNA to be significantly up-regulated in ovarian cancer (14, 20, 21).
Prognostic value of quantitatively assessed KLK7 expression in ovarian cancer.
Recent reports have linked high KLK7 [8] expression to a significantly poorer prognosis in ovarian and breast cancer, indicating that KLK7 may be a potent prognostic marker for ovarian and breast cancer (12-14).
Because the HSCCE gene (a) is located next to other members in the human kallikrein family, (b) has the same genomic organization and intron phase as other members of this family and (c) has significant homology to other members of the family in both the DNA and amino acid sequences (7), HSCCE is now considered to be a member of the human kallikrein family and has been given a new name, KLK7 for the gene and human kallikrein 7 (hK7) for the protein (8).
Fine mapping of the area indicates that KLK6 lies between the KLK5 and KLK7 genes (9).
Previously, several other kallikreins, including KLK4, KLK5, KLK6, KLK7, KLK8, KLK9, KLK10, KLK11, KLK14, and KLK15, have been associated with various forms of malignancy and especially cancers of the ovary, breast, prostate, and testis [reviewed in Refs.
KLK7 is up-regulated in ovarian cancer (62), and KLK4 and KLK5 are indicators of poor prognosis of ovarian cancer (63-65).
