(Submitter supplied) Fuchs’ endothelial corneal dystrophy (FECD) is a progressive vision impairing disease caused by thickening of Descemet’s membrane and gradual degeneration and loss of corneal endothelial cells. The aim of this study was to identify differentially expressed genes between FECD-affected and unaffected corneal endothelium to gain insight into the pathophysiological mechanisms underlying this disease. Microarray gene expression analysis was performed on total RNA from FECD-affected and unaffected corneal endothelium-Descemet’s membrane (CE-DM) specimens using the Illumina HumanHT-12 v3.0 expression array. more...

(Submitter supplied) PURPOSE: To compare the gene expression profiles of normal human corneal endothelium with Fuchs' corneal endothelium, by using serial analysis of gene expression (SAGE). METHODS: Three pairs of normal human corneas were obtained from eye banks. Thirteen bisected Fuchs' corneal buttons were processed at the time of corneal transplantation. The endothelia of normal and Fuchs'-affected corneas were stripped, and total RNA was isolated. more...

(Submitter supplied) 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. We used microarrays to comprehensively characterize human corneal endothelial cell (HCEnC) gene expression, age-dependent differential gene expression and to identify expressed genes mapped to chromosomal loci associated with the corneal endothelial dystrophies PPCD1, FECD4 and XECD

(Submitter supplied) PURPOSE: Fuchs’ endothelial corneal dystrophy (FECD) is a degenerative eye disorder affecting 4% of Americans older than 40. It is the leading indication for corneal endothelial (CE) transplantation for which there is a global donor shortage. This study aimed to gain further insight into the pathophysiology of FECD and identify targets for nonsurgical therapy. METHODS: CE from patients with late-onset FECD was compared with that of normal controls using microarray expression analysis (n = 4 FECD, n = 4 normal), reverse transcriptase quantitative PCR (n = 9 FECD, n = 8 normal), and immunohistology (n = 55 FECD, n = 15 normal). more...

(Submitter supplied) Transparency of the human cornea is necessary for vision. Fuchs Endothelial Corneal Dystrophy (FECD) is a bilateral, heritable degeneration of the corneal endothelium, and a leading indication for corneal transplantation in developed countries. While the early onset, and rarer, form of FECD has been linked to COL8A2 mutations, the more common, late onset form of FECD has genetic mutations linked to only a minority of cases. more...

(Submitter supplied) How genetic defects trigger late-onset disease is important for understanding disease progression and therapeutic development. Fuchs’ endothelial corneal dystrophy (FECD) is an RNA-mediated disease caused by a trinucleotide CUG expansion in an intron within the TCF4 gene. The mutant intronic CUG RNA is present at 1-2 copies per cell, posing a challenge to understand how a rare RNA can cause disease. more...

Here we used RNA-Seq with the goal of finding pathways related to corneal endothelial metabolic, pump and barrier function alterations.

(Submitter supplied) Corneal endothelium is composed of a monolayer of corneal endothelial cells (CECs) in the inner layer of cornea, which is essential for maintaining corneal transparency. In order to better characterize CECs in different developmental stages, we profiled mRNA transcriptomes in human fetal and adult corneal endothelium with the goal to identify novel molecular markers in these cells. By comparing CECs with 12 other types of tissues, we identified 245 and 284 signature genes that are highly expressed in fetal and adult CECs, respectively. more...

(Submitter supplied) Phenotypic heterogeneity among arterial ECs is particularly relevant to atherosclerosis since the disease occurs predominantly in major arteries, which vary in their atherosusceptibility. To explore EC heterogeneity, we used DNA microarrays to compare gene expression profiles of freshly harvested porcine coronary and iliac artery ECs. We demonstrate that in vivo the endothelial transcriptional profile of a coronary artery (the right coronary artery) is intrinsically different from that of a major conduit vessel (the external iliac artery), and that this difference is consistent with former vessel being more prone to atherosclerosis. more...
