Analysis of conjunctival (Cnj) and corneal (Co) epithelia, the main cellular components of the ocular surface. Cnj and Co epithelia are embryologically related but phenotypically and functionally disparate. Results provide insight into the molecular basis of these differences.

(Submitter supplied) PURPOSE. To determine global mRNA expression levels in the corneal and conjunctival epithelia and identify transcripts that exhibit preferential tissue expression. METHODS. cDNA samples derived from human conjunctival and corneal epithelia were hybridized in three independent experiments to a commercial oligonucleotide array representing > 22,000 transcripts. The resulting signal intensities and transcript present/absent calls by the primary microarray analyzing software were used in conjunction with a statistical method to identify transcripts that are preferentially or exclusively (transcripts absent in all three replicates in the other tissue) and significantly (expression >1% of the ß-actin level) expressed in one of the two tissues. more...

(Submitter supplied) The identification of a marker that is expressed in the conjunctival epithelium but not in the corneal epithelium has been a growing need. A more specific marker of limbal and conjunctival epithelia would be necessary to detect non-corneal epithelial cells on the corneal surface. To search for conjunctival specific marker(s), we first performed preferential gene profiling in the conjunctiva in direct comparison to that in the cornea using microarray technique.

(Submitter supplied) Side population (SP) cells isolated from limbal and conjunctival epithelia derive from cells that are slow cycling in vivo, a known feature of tissue stem cells. The purpose of this study was to define the molecular signature of the conjunctival side population cells by global differential gene expression to identify markers and signaling pathways associated with this cell phenotype. Four overnight cultures of freshly isolated human conjunctival epithelial cells stained with Hoechst 3342 were cytometrically sorted into SP and non-SP cohorts. more...

(Submitter supplied) Purpose. How vitamin A contributes to the maintenance of the wet-surfaced phenotype at the ocular surface is not well understood. We sought to identify vitamin A responsive genes in ocular surface epithelia using gene microarray analysis of cultures of a human conjunctival epithelial cell line (HCjE) grown with all-trans-retinoic acid (RA). The analysis showed that the membrane-associated mucin MUC16 was induced by RA and that secretory phospholipase A2 Group IIA (sPLA2-IIA), the gene most upregulated by RA, was induced earlier. more...

(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...

(Submitter supplied) Purpose: To identify the changes in postnatal mouse conjunctival forniceal gene expression and their regulation by Klf4 around eye opening stage when the goblet cells first appear. Methods: Laser-capture-microdissection was used to collect conjunctival forniceal epithelial cells from postnatal-day (PN) 9, PN14 and PN20 wild-type (WT), and PN14 Klf4-conditional null (Klf4CN) mice, where goblet cells are absent, developing, present, and missing, respectively. more...

(Submitter supplied) Human conjunctival cell lines are useful tools for modeling ocular surface disease and evaluation of ocular drugs. Here we demonstrate that the IOBA-NHC and the ChWK conjunctival epithelial cell lines show, using an unbiased gene microarray approach, unique gene expression signatures that differ from primary conjunctival epithelial cells (PCEC) and conjunctival tissue. Globally, the expression profile obtained with the Affymetrix U133A chip (>22000 genes) from PCEC was clustered more closely to conjunctival tissue than either of the 2 cell lines. more...

(Submitter supplied) Microarray was used to study global gene expression of a cell culture model based on SV40-immortalized human corneal epithelial (iHCE) cells. The gene expression profile of the cell line was compared to the normal human corneal epithelium. Affymetrix HG-U133A GeneChips® were used for microarray experiments and results were validated by performing RT-qPCR for selected genes. iHCE was found to over- and under-express 22 % and 14 % of the annotated genes, respectively. more...

Analysis of regulation of immortalized human conjunctival epithelial cells by dihydrotestosterone at gene expression level.

(Submitter supplied) Recently we reported that the rat inner retina undergoes significant functional changes during maturation. Aiming to gain knowledge on additional aspects of retinal development and maturation, we used the microarray system to monitor gene expression patterns in the rat retina at ages 5, 11, and 20 weeks. The analysis revealed the expression of many well-documented retinal genes as well as a high number of non–annotated genes. more...

(Submitter supplied) Objectives. Sex-associated differences have been identified in the anatomy, physiology and pathophysiology of the human cornea. We hypothesize that many of these differences are due to fundamental variations in gene expression. Our objective in this study was to determine whether such differences do exist in human corneal epithelial cells both in vivo and in vitro. Methods. Human corneal epithelial cells were isolated from the corneoscleral rims of male and female donors. more...

(Submitter supplied) Remodeling of the actin cytoskeleton through actin dynamics (assembly and disassembly of filamentous actin) is known to be essential for numerous basic biological processes. In addition, recent in vitro studies provided evidence that actin dynamics participate in the control of gene expression. A spontaneous mouse mutant, corneal disease 1 (corn1), is deficient for a regulator of actin dynamics, destrin (DSTN; also known as actin depolymerizing factor or ADF), and develops epithelial hyperproliferation and neovascularization in the cornea. more...
