Existence of the Canonical Wnt Signaling Pathway in the Human Trabecular Meshwork |pdf=|usr=}}{{22956608}} gab.com Text Existence of the Canonical Wnt Signaling Pathway in the Human Trabecular Meshwork JO: Invest Ophthalmol Vis Sci http://www.kidney.de/pget.php?&tw=1&pmid=22956608 #FOAvip Purpose.We previously discovered elevated levels of secreted frizzled-related protein 1 (sFRP1), the Wnt signaling pathway inhibitor, in the glaucomatous trabecular meshwork (GTM), and found that key canonical Wnt signaling pathway genes are expressed in the trabecular meshwork (TM). The purpose of our study was to determine whether a functional canonical Wnt signaling pathway exists in the human TM (HTM). Methods.Western immunoblotting and/or immunofluorescent microscopy were used to study ?-catenin translocation as well as the actin cytoskeleton in transformed and primary HTM cells. A TCF/LEF luciferase assay was used to study functional canonical Wnt signaling, which was confirmed further by WNT3a-induced expression of a pathway target gene, AXIN2, via quantitative PCR. Intravitreal injection of an Ad5 adenovirus expressing Dickkopf-related protein-1 (DKK1) was used to study the in vivo effect of canonical Wnt signaling on IOP in mice. Results.WNT3a induced ?-catenin translocation in the HTM, which was blocked by co-treatment with sFRP1. Similarly, WNT3a enhanced luciferase levels in TCF/LEF luciferase assays, which also were blocked by sFRP1. Furthermore, AXIN2 expression was elevated significantly by WNT3a. However, neither WNT3a nor sFRP1 affected actin cytoskeleton organization, which theoretically could be regulated by noncanonical Wnt signaling in HTM cells. Exogenous DKK1, a specific inhibitor for the canonical Wnt signaling pathway, or sFRP1 elevated mouse IOP to equivalent levels. Conclusions.There is a canonical Wnt signaling pathway in the TM, and this canonical Wnt pathway, but not the noncanonical Wnt signaling pathway, regulates IOP.
