Abstract
Expression and production of MMP-9, -1, -13, and -3 by human corneal epithelial cells correlated positively with increasing media osmolarity. This increase was mediated at least in part through activation of the JNK SAPK pathway. Doxycycline, an agent used to treat MMP-mediated ocular surface disease, inhibited the hyperosmolarity-induced MMP production and JNK activation. The relevance of these findings to stimulated production of MMPs by the elevated tear osmolarity in dry eye remains to be determined.
