A recent case-control study based on the LC-MS/MS and iTRAQ found 50 altered proteins (39 overexpressed and 11 subexpressed); three of them were validated through ELISA: alpha-enolase, IL-18, and KLK13 .
controls BMS No significant differences BMS No significant differences BMS [up arrow] Alpha-enolase, [up arrow] IL-18, and [up arrow] KLK13 in BMS vs.
KLK11, KLK13, and KLK14 were measured as previously described (18, 19) (see Supplemental Data section in the online Data Supplement).
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.

predict tumor recurrence in epithelial ovarian carcinoma," British Journal of Cancer, vol.
KLK13 was found at high concentrations in the esophagus and tonsil.
KLK13 was found at highest concentrations in CVF, followed by seminal plasma and saliva.
For example, we found that KLK6 and KLK13
have a splice variant with 3'-coding exon 3 extension by ~100 by (close to the length of the retained intron III in the genes examined here).
KLK13, previously known as KLK-L4, is one of the newly identified kallikrein genes.
CLONING OF KLK13 CDNA INTO THE YEAST EXPRESSION SYSTEM
A noteworthy pattern related to the hormonal regulation is that the centromeric and telomeric groups of kallikreins (KLK1 to -4 and KLK13
to -15) are up-regulated mainly by androgens, whereas the central group is up-regulated mainly by estrogens.
