abstract = {AIMTo identify metabolites, proteins, and related pathways involved in the etiology of rhegmatogenous retinal detachment (RRD) for use as biomarkers in diagnosing and treating RRD.METHODSVitreous specimens were collected and liquid chromatography-tandem mass spectrometry analysis was performed using the four-dimensional label-free technique. Statistically significant differentially expressed proteins, gene ontology (GO) terms, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway representations, and protein interactions were analyzed.RESULTSNine specimens were subjected to proteomic analysis. In total, 161 proteins were identified as differentially expressed proteins (DEPs), including 53 upregulated proteins and 108 downregulated proteins. GO functional analysis revealed that some DEPs were enriched in neuron-related terms and membrane protein terms. Moreover, KEGG analysis indicated that the cell adhesion molecule metabolic pathway was associated with the greatest number of DEPs. Finally, the evaluation of protein-protein interaction network revealed that DEPs were clustered in neuronal adhesion, apoptosis, inflammation and immune responses, correct protein folding, and glycolysis.CONCLUSIONProteomic profiling is useful for the exploration of molecular mechanisms that underlie RRD. This study reveals increased expression levels of proteins related to heat shock protein content, glycolysis, and inflammatory responses in RRD. Knowledge regarding biomarkers of RRD pathogenesis may help to prevent the occurrence of RRD in the future.}
