Affymetrix Human Gene 1.1 ST Array (hugene11st)
Description
Defining the normal and age-dependent HCEnC transcriptome will further refine our understanding of the functional roles that the endothelium plays in the cornea and will provide a basis upon which to compare transcriptomes of normal and dystrophic endothelium for the subsequent development of gene-targeted therapies.
Publication Title
Transcriptome analysis of the human corneal endothelium.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
To date, there is no specific marker for limbal epithelial stem cells. The identification of a marker that is expressed in the limbal epithelium but not in the cornea or conjunctiva epithelium has been a growing need. To search for limbal-specific marker(s), we performed preferential gene profiling in the limbus in direct comparison to that in the cornea and conjunctiva using microarray technique.

Description
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.

Keratin 13 is a more specific marker of conjunctival epithelium than keratin 19.

Description
Our objective was to determine the nature and extent of androgen regulation of gene expression in the female lacrimal, meibomian,and submandibular glands, and to explore the degree to which this control is the same as in male glands.
Publication Title

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Although there have been studies conducted on cornea and retina growth and development, postnatal gene expression studies on sclera growth during postnatal growth has not been well characterised. Given that the mouse genome has 85% homology to the human genome and has been completely sequenced, mouse model for the study of ocular growth has advantages over other animal models. Thus, we aimed to study the biology and genetics behind sclera growth during post-natal development in Balb/cJ mice as a means to understand genetic changes that cause scleral growth and development during post-natal eye development

Description
Using a hitherto uncharacterized knockout mouse model of Notch 3, a Notch signaling receptor paralogue highly expressed in vascular SMCs, we uncover a striking susceptibility to ischemic stroke upon challenge. Cellular and molecular analyses of vascular SMCs derived from these animals associate Notch 3 activity to the expression of specific gene targets, whereas genetic rescue experiments unambiguously link Notch 3 function in vessels to the ischemic phenotype.

Description
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. Since eicosanoids, metabolites of arachidonic acid, which is produced by sPLA2 catalysis of membrane phospholipids, have been demonstrated to affect mucin production, we sought to determine if the sPLA2 induction in HCjE cells was associated with RA induction of MUC16.

Description
Goblet cell numbers decrease within the conjunctival epithelium in drying and cicatrizing ocular surface diseases. Factors regulating goblet cell differentiation in conjunctival epithelium are unknown. Recent data indicate that the transcription factor SAM-pointed domain epithelial-specific transcription factor (Spdef) is essential for goblet cell differentiation in tracheobronchial and gastrointestinal epithelium of mice. Using Spdef -/- mice, we determined that Spdef is required for conjunctival goblet cell differentiation and that Spdef -/- mice, which lack conjunctival goblet cells, have significantly increased corneal surface fluorescein staining and tear volume, a phenotype consistent with dry eye.
