Glycobiology of ocular angiogenesis

Ocular neovascularization can affect almost all the tissues of the eye: the cornea, the iris, the retina, and the choroid. Pathological neovascularization is the underlying cause of vision loss in common ocular conditions such as diabetic retinopathy, retinopathy of prematurity and age-related macular neovascularization. Glycosylation is the most common covalent posttranslational...

Molecular basis for MMP9 induction and disruption of epithelial cell–cell contacts by galectin-3

Zhiyi Cao Noorjahan Panjwani Pablo Argu eso () Dynamic modulation of the physical contacts between neighboring cells is integral to epithelial processes such as tissue repair and cancer dissemination

Galectin-8 Promotes Cytoskeletal Rearrangement in Trabecular Meshwork Cells through Activation of Rho Signaling

Purpose The trabecular meshwork (TM) cell-matrix interactions and factors that influence Rho signaling in TM cells are thought to play a pivotal role in the regulation of aqueous outflow. The current study was designed to evaluate the role of a carbohydrate-binding protein, galectin-8 (Gal8), in TM cell adhesion and Rho signaling. Methods Normal human TM cells were assayed for...

Analysis of differential expression of glycosyltransferases in healing corneas by glycogene microarrays

It is generally accepted that the glycans on the cell surface and extracellular matrix proteins play a pivotal role in the events that mediate re-epithelialization of wounds. Yet, the global alteration in the structure and composition of glycans, specifically occuring during corneal wound closure remains unknown. In this study, GLYCOv2 glycogene microarray technology was used for...

The role of integrin glycosylation in galectin-8-mediated trabecular meshwork cell adhesion and spreading

Primary open angle glaucoma (POAG) is a major blindness-causing disease, characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork (TM) lining the aqueous outflow pathway modulates the aqueous outflow facility. TM cell adhesion, cell–matrix interactions, and factors that influence Rho signaling in TM cells are thought...
