Kallikrein-Related Peptidase mRNA Expression in Adenoid Cystic Carcinoma of Salivary Glands: A Polymerase Chain Reaction Study.

Kallikrein-related peptidases (KLKs) are a group of 15 serine proteases implicated in a variety of biological processes. Aberrant expression of KLKs has been associated with the development of certain cancers. However, the role of KLKs in salivary tumors has not been extensively studied.

Kallikrein-related peptidase expression in odontogenic cysts and tumors: An immunohistochemical comparative study.

Aim: The aim of the present study was to profile the expression of human kallikrein (KLK)-related peptidases (KLK) in odontogenic lesions.

Methods: Paraffin-embedded, formalin-fixed, non-odontogenic (control) and odontogenic lesions were stained for KLK using a standard immunohistochemical technique. The intensity and proportion of epithelial cells stained was scored.
