Comparison of gene expression profile of human trabecular meshwork cells induced by triamcinolone with dexamethasone

(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...

Glucocorticoid Induced Changes in Gene Expression in Human Lens Epithelial Cells

(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...

Influence of cyclical mechanical strain on global gene expression in human lamina cribrosa cells in vitro

(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...

Expression profiling of skeletal muscle in beef cattle treated with steroidal growth promoters

(Submitter supplied) In the present study, a oligonucleotide microarray platform is used to compare expression profiles of beef cattle muscle in animals treated with either Dexamethazone (Dex) or Dexamethazone plus 17β-estradiol (Estr) administered at sub-therapeutic dosage, against untreated controls. Seventeen male beef cattle 15-18 months old, around 450 kg mean body weight were randomly allocated in three groups: 6 were untreated (group Ctrl), 5 were administered with dexamethazone via feed 0.75mg/head for 43 days (group D); the last 6 animals were administered via feed for 43 days with Dex (0.75mg/head) and intramuscularly (i.m.) for three times with 17β-oestradiol, 20mg/head, (group DE). more...

TGF-beta regulated gene transcription and protein expression in human GFAP-negative lamina cribrosa cells

(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...

Microarray analysis of changes in gene expression within the amacrine cell layer of chicks following optical defocus

(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...

Comparative gene expression in the limbus of the vervet monkey

(Submitter supplied) The limbus is a unique anatomic structure that is highly innervated and vascularized yet sets the boundary for the avascularized cornea. The corneal epithelial stem cells are believed to reside at the limbus. The intrinsic and external molecular signals that modulate the differentiation and proliferation of the limbal stems cells are still largely unidentified because of a lack of known specific markers. more...

Microarray Analysis of Retinal Gene Expression in the DBA/2J Model of Glaucoma

(Submitter supplied) Purpose: The DBA/2J mouse is a model for secondary angle-closure glaucoma due to iris atrophy and pigment dispersion, which ultimately leads to increased intraocular pressure (IOP). We sought to correlate changes in retinal gene expression with glaucoma-like pathology by performing microarray analysis of retinal RNA from DBA/2J mice at 3 months before disease onset, and at 8 months, after IOP elevation. more...

Expression data from brain tissue of Rattus norvegicus treated with D-Serine

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...
