Cystatin a, a potential common link for mutant myocilin causative glaucoma.

Myocilin (MYOC) is a 504 aa secreted glycoprotein induced by stress factors in the trabecular meshwork tissue of the eye, where it was discovered. Mutations in MYOC are linked to glaucoma. The glaucoma phenotype of each of the different MYOC mutation varies, but all of them cause elevated intraocular pressure (IOP). In cells, forty percent of wild-type MYOC is cleaved by calpain II, a cysteine protease. This proteolytic process is inhibited by MYOC mutants. In this study, we investigated the mol ...[more]

Risk Variants for Exfoliation Syndrome Modulate Antisense Promoter Activity Within the LOXL1 Locus

Project description:The goal of this study was to identify functional variants that play a role in exfoliation syndrome (XFS) pathogenesis. We sequenced the entire LOXL1 locus in 50 South African XFS cases and 50 matched controls. The most strongly associated variants in this dataset were found in a ~7kb region spanning the LOXL1 exon 1/intron 1 boundary. DNase hypersensitivity analysis was used to demonstrate that this region, which lies upstream of the LOXL1 antisense RNA (LOXL1-AS1), contains regulatory activity. determining of chromatin structural changes in 3 cell types.

Multi-omics analyses reveal the mechanical-stress-dependent changes in trabecular meshwork cytoskeletal-extracellular matrix interactions

Project description:Trabecular meshwork (TM) tissue is subjected to constant mechanical stress due to the ocular pulse created by the cardiac cycle. This induces alterations in membrane lipids and associated cell-cell adhesion and cell-extracellular matrix (ECM) interactions triggering intracellular signaling responses to counter mechanical insults. A loss of such response can lead to elevated intraocular pressure (IOP), a major risk factor for primary open-angle glaucoma. The purpose of this study was to understand the response of TM under mechanical stretch using a multi-omics approach. We performed an unbiased mRNA sequencing for changes in transcripts, mass spectrometry (MS)-based quantitative proteomics for protein changes, and multiple reaction monitoring (MRM) profiling based MS and HPLC-based MS to identify lipid changes. With the help of the multi-omics data analysis on human TM cells under mechanical stress, we provide evidence for the regulation of TM actin cytoskeleton and ECM interactions at the mRNA and protein levels, which can further modulate the TM lipids contents effectively regulating the mechanical properties of TM membrane. Overall, in this study, we propose the mechanistic interplay of macromolecules to bring about a concerted cellular response in TM cells to achieve mechanotransduction and IOP regulation

Dexamethasone induced gene expression changes in the human trabecular meshwork

Project description:One of the undesirable side effects of glucocorticoid use is the potential development of elevated intraocular pressure and glaucoma. The precise mechanisms through which steroid use induces ocular hypertension are unclear. The purpose of this study was to identify gene expression changes induced by steroids in the human trabecular meshwork and the underlying sclerocorneal tissue. The anterior segment of five pairs of adult human donor eyes were maintained in a profusion organ culture system.

Effects of dexamethasone for primary trabecular meshwork cell gene expression

Project description:To clarify the effects of dexamethasone treatment for primary trabecular meshwork cell gene expression, which may relates to the pathophysiology of glucocorticoid-induced glaucoma Three lots (lot #2584, 3423 and 4973) of primary culture human trabecular meshwork (TM) cells were purchased from ScienCell Research Laboratories (Carlsbad, CA). The TM cells were treated with and without 100nM dexamethasone (DEX) for 14 days. Genomewide gene expression analysis was carried out using Agilent 8X60K array.

Expression data from pooled RNA of various ocular tissues

Project description:The normal gene expression profiles of the tissues in the eye are a valuable resource for considering genes likely to be involved with disease processes. This is based on the assumption that transcript abundances in healthy tissue are correlated to the continued health of that tissue. Expression values were compared with publically available EST and RNA-sequencing resources. The estimated gene and exon level abundances are available online on the Ocular Tissue Database. Ten different tissues were obtained from 6 different individuals and RNA was pooled. The tissues included: retina, optic nerve head (ONH), optic nerve (ON), ciliary body (CB), trabecular meshwork (TM), sclera, lens, cornea, choroid/RPE and iris.

The proteome of normal human sclera

Project description:The sclera provides an opaque protective coat for five-sixths of the surface of the human eye. A detailed investigation of the proteome of the normal human sclera may provide insights into the biology and pathophysiology of the sclera. We conducted an in-depth proteomic analysis of sclera from five adults. Proteins were fractionated using SDS-PAGE. After in-gel digestion, peptides were analyzed using LC-MS/MS on an Orbitrap Elite mass spectrometer. We identified 1952 non-redundant proteins in the human sclera, including 18 different collagen protein chains (types 1, II, III, IV, VI, VIII, X, XII, XIV, XV, XVI, XVIII), proteins of the small leucine-rich proteoglycan family (decorin, biglycan, lumican, keratocan, prolargin, fibromodulin, and mimecan), non-collagenous glycoproteins (fibronectin, vitronectin, and laminin), extracellular matrix proteins (thrombospondins 1, 2, 3, 4, dystroglycan, and transgelins 1, 2, 3), matrix metalloproteinases 3 and 14, matrix metalloproteinase inhibitors 1, 2, and 3, and integrins alpha-V, alpha-1, alpha-2, beta-1, beta-2, and beta-5.
