mRNA levels of the lysosomal cysteine protease Cathepsin K were quantified by real-time PCR analysis and normalized with 18 s RNA expression. There was a significant increase in Cathepsin K mRNA expression for three LC samples from glaucoma donors relative to three samples from donors without glaucoma with a mean fold difference of 2.1 ± 1.2, p = 0.04.
