Project description:Fuchs’ endothelial corneal dystrophy is major corneal disorder in the western world affecting the innermost part of the cornea, which leads to visual impairment. The morphological changes observed in Fuchs’ endothelial corneal dystrophy is well described, however, much less in known of the pathology at the molecular level. As the morphological changes observed in the cornea is profound in the extracellular matrix we sought to determine in protein profiles and changes herein in the Descement’s membrane and endothelium layer of Fuchs’ endothelial conrneal dystrophy patients when compared to healthy control tissue. Using the extracted ion chromatogram label-free MS based quantification method we quantified approximately the 50 most abundant proteins of the Descemet’s membrane and endothelial layer in in patient and control tissue. In addition, using the isobaric tag for relative and absolute quantification MS method resulted in a total of 22 regulated proteins of which the majority were extracellular proteins known to be involved in proper assembly and modulation of the basement membrane in other tissues. Many of the regulated proteins were furthermore among the most abundant proteins quantified. The two MS methods performed here suggest altered arrangement of the extracellular matrix in Fuchs’ endothelial corneal dystrophy and provide new candidate proteins that may be involved in molecular mechanism of this disease.

Project description:Fuchs endothelial corneal dystrophy (FECD) is a vision impairing pathology affecting the endothelial cells of the cornea. To better understand the disease, we developed a method to cultivate FECD cells isolated from surgical specimens. Using gene profiling, we compared the mRNA profiles of passage 2 FECD cells with passage 2 non-pathological corneal endothelial cells isolated from eye bank donor corneas.

Project description:This dataset contains proteomic profiles of Descemet's membrane (DM) with corneal endothelial cells derived from patients with Fuchs endothelial corneal dystrophy (FECD) and non-FECD subjects by shotgun proteomics. FECD is the most common inherited corneal disease. Fibrillar focal excrescences, called guttae, and corneal edema due to corneal endothelial cell death result in progressive vision loss. Our dataset indicated that 32 distinctive molecules were expressed only in the FECD-DM but not in the DM of the control subject, possibly having important roles in the pathophysiology of FECD.

Project description:<p>Fuchs' Endothelial Corneal Dystrophy (FECD) is a common disease that results in loss of vision associated with progressive corneal edema and loss of corneal transparency. In the initial stages of the disease, excrescences on Descemet's membrane with the appearance of an abnormal posterior collagenous layer, result in the clinical and pathologic appearance of guttae. Corneal edema ensues as endothelial function is compromised that may result in stromal edema, epithelial edema, and painful bullous keratopathy. Penetrating or endothelial keratoplasty is the only definitive treatment, with palliative care the only option prior to surgery. The pathophysiology underlying FECD, particularly in the common cases that affect older individuals, remains unknown, with a genetic predisposition being reported as the single best predictor of disease.</p> <p>Three independent groups funded by the National Eye Institute (NEI), with well-established programs in the genetics of FECD, conducted a genome-wide association study of FECD. The collaboration comprised investigators from Case Western University (CWRU), Duke University (DUEC), and Johns Hopkins University (JHU). CWRU and DUEC contributed samples that were genotyped at CIDR for the GWAS. Johns Hopkins University (JHU) provided samples for the replication phase of the study, where their data are not listed in dbGaP. Cohorts of FECD cases and controls were assembled. Synchronization of clinical and coded data was performed to unify the information across centers. The family history, clinical, demographic information, and genome-wide genotype data for samples from CWRU and DUEC were deposited in dbGaP.</p>
