Dexamethasone Induces Cross-Linked Actin Networks in Trabecular Meshwork Cells Through Noncanonical Wnt Signaling

摘要

Purpose.Dexamethasone (DEX) regulates aqueous humor outflow by inducing a reorganization of the cytoskeleton to form cross-linked actin networks (CLANs) in trabecular meshwork (TM) cells. Rho-associated protein kinase (ROCK) has been demonstrated to have an important role in this process, but the upstream components leading to its activation remain elusive. The purpose of the study is to demonstrate that noncanonical Wnt signaling mediates the DEX-induced CLAN formation in TM cells.
