(Submitter supplied) The mechanical effect of raised intraocular pressure is a recognised stimulus for optic neuropathy in primary open angle glaucoma (POAG). Characteristic extra-cellular matrix (ECM) remodelling accompanies axonal damage in the lamina cribrosa (LC) of the optic nerve head in POAG. Glial cells in the lamina cribrosa may play a role in this process but the precise cellular responses to mechanical forces in this region are unknown. more...

(Submitter supplied) Primary open angle glaucoma (POAG) is a progressive optic neuropathy, which is a major cause of worldwide visual impairment and blindness. Pathological hallmarks of the glaucomatous optic nerve head include retinal ganglion cell axon loss and extracellular matrix (ECM) remodeling of the lamina cribrosa layer. TGF-beta is an important pro-fibrotic modulator of ECM metabolism, whose levels are elevated in human POAG lamina cribrosa tissue compared with non-glaucomatous controls. more...

(Submitter supplied) Purpose: Marked extracellular matrix (ECM) remodeling occurs in the human optic nerve head in primary open angle glaucoma (POAG). The glial fibrillary acid protein (GFAP) negative lamina cribrosa cell may play an important role in this remodeling process. The authors report the first study of global and ECM-focused gene transcription differentials between GFAP-negative negative lamina cribrosa (LC) cells from normal and POAG human donors. more...

(Submitter supplied) Prolonged use of glucocorticoids can lead to the formation of a cataract, however the mechanism is not known. We recently reported the presence of the functional glucocorticoid receptor in immortalized cultured mammalian lens epithelial cells (Gupta & Wagner, Invest Ophthalmol Vis Sci 2003), but the short term biological effect of glucocorticoid action in lens epithelial cells is not known. This study seeks to examine glucocorticoid induced changes in global gene expression in LECs. more...

(Submitter supplied) PURPOSE. Triamcinolone acetonide (TA) and dexamethasone (DEX) are corticosteroids commonly used for ocular inflammation but both can cause ocular hypertension. We investigated the differential gene expression profile of human trabecular meshwork (TM) cells in response to treatment by TA compared to that by DEX. METHODS. Total RNA was extracted from cultured human TM cells treated with TA or DEX and used for microarray gene expression analysis. more...

(Submitter supplied) Gene expression in human optic nerve head (ONH) astrocytes exposed to either 60 mm Hg hydrostatic pressure (HP) or control ambient pressure (CP) was compared using Affymetrix GeneChip microarrays to identify HP-responsive genes. Primary ONH astrocytes from two male Caucasian donors (passage 4) were grown to 75% confluence and were exposed for 6, 24 or 48 h to control ambient pressure (CP6, CP24, CP48) or hydrostatic pressure (HP6, HP24, HP48), or harvested at the beginning of the pressure experiment (CP0). more...

(Submitter supplied) Ocular growth is regulated locally by signals produced in the retina that ultimately act on the growth of the scleral tissue. Consequently, a number of studies have investigated changes in retinal gene expression during manipulation of ocular growth in an attempt to elucidate the biochemical pathways underlying eye growth. However, due to the highly heterogenous nature of the retina, important changes in gene expression can be masked. more...
