Proteomics of Fuchs- Endothelial Corneal Dystrophy support that the extracellular matrix of Descemet-s membrane is disordered.

Data from ProteomeXchange, PXD ID: PXD000746. Experiment: label-free, file: 2012-10-05 - ETP - Fuchs - Control - 3-2.mgf. Published as part of J Proteome Res. 2014 May 21 . From the Abstract: {{i}} Fuchs- endothelial corneal dystrophy (FECD) is a major corneal disorder affecting the innermost part of the cornea, leading to visual impairment. As the morphological changes in FECD are mainly observed in the extracellular matrix of the Descemet-s membrane/endothelial layer we determined the protein profiles of diseased and control tissues using two relative quantitation MS methods. The first quantitation method based on the areas of the extracted ion chromatograms, quantified the 51 and 48 most abundant proteins of the Descemet-s membrane/endothelial layer in patient and control tissues, respectively, of which 10 were significantly regulated. The results indicated that the level of type VIII collagen was unaltered even though the protein previously has been implicated in familial early onset forms of the disease. {{/i}}
