“…Similarly, the human kallikrein-related peptidases, KLK2 and KLK13 (Lundwall et al, 2006), which show a sequence identity of 32% and 37%, respectively, with the catalytic domain of T-SP1/1, are highly expressed not only in testis but also in ovarian cancer tissues (Tremblay et al, 1996;Petraki et al, 2003;Scorilas et al, 2004;Dorn et al, 2007 (Yousef and Diamandis, 2003). Therefore, it seems possible that T-SP1 may also act as a marker of certain tumors, because we could show its protein expression in human ovarian cancer tissues as well as in glandular differentiated prostate carcinoma, where it may be upregulated by hormones.…”
