Fifteen proteins were found to be increased in OM (Figure 4A) and seven in PM (Figure 4B) that were also enriched in fibrotic human valve tissue, including glial fibrillary acidic protein (GFAP), alanyl aminopeptidase (ANPEP), and dermcidin (DCD) in both OM and PM. Here, ANPEP is linked to ocular melanoma.
