Uncovering a Glaucoma-Linked Lysophosphatidic Acid-MAPK/AP-1 Fibrosis Axis in Human Trabecular Meshwork Cells and Its Modulation by <i>Diospyros kaki</i> Leaf Extract.

ABSTRACT: Dysregulated extracellular matrix (ECM) deposition and epithelial-mesenchymal transition (EMT) in the trabecular meshwork (TM) contribute to glaucoma-associated fibrotic remodeling, and lysophosphatidic acid (LPA) potently induces these profibrotic responses in human trabecular meshwork (HTM) cells. We investigated whether an ethanolic extract of Diospyros kaki leaves (EEDK) attenuates LPA-induced fibrosis and explored the underlying mechanisms. HTM cells were stimulated with LPA and treated with ethanol-based EEDK extracts. Expression of ECM/fibrosis-related genes (FN1, ACTA2, COL1A1, COL3A1, COL4A1, COL6A2, CCN2) and EMT markers (CDH2, VIM, SNAI1) was assessed, along with cell migration using a wound-healing ass
