KLK14 and posterior cortical atrophy: To decipher the molecular and biological roles of increased KLK14 expression in PCa cells, we expressed, under the control of a doxycycline‐inducible promoter, three variants in LNCaP cells: the wild‐type KLK14 (iKLK14), the catalytic‐mutant KLK14 (imKLK14), and the GFP sequence (iGFP).
