pathway and network analysis in primary open angle glaucoma
نویسندگان
چکیده
glaucoma, a group of multifactor ocular diseases, is the second leading cause of blindness worldwide. primary open angle (poa) is the most common type of glaucoma, characterized by progressive optic nerve degeneration. numerous genes and proteins have been revealed to be associated with poag, but the pathologic mechanisms of the disease are still poorly understood. proteomics, the collective study of proteins in an organism at a given condition, has extensively been used for the high-throughput identification of proteins related to poag. a significant obstacle in proteomics studies is the data variability which makes it hard to interpret the results. pathway analysis and network topological information can help address the challenge and provide a greater appreciation of the disease mechanism and progression. the purpose of this paper is to determine poag biological and network information to further understand the mechanisms associated with poag. panther classification system was used, including classification with gene ontology, protein class and pathway. 474 gene/protein ids were extracted from previous proteomic studies. among pathways found by panther classification, apoptosis signaling pathway was the most significant pathway (with the p-value of 5.54e-12). other panther categories results demonstrated that developmental processes, receptor binding, extracellular region and extracellular matrix proteins were the most significant biological process, molecular function, cellular component and protein class respectively. pathway analysis aids to find probable mechanisms involved in poag. a network analysis on proteins was also performed using string database and cytoscape software. from network analysis, candidate biomarkers for the disease were introduced.

Primary open-angle glaucoma
Primary open-angle glaucoma (POAG) is an idiopathic disorder in which the resistance to outflow through the trabecular meshwork gradually increases and the intraocular pressure (IOP) rises, causing irreversible damage to the optic nerve POAG is the second most common cause of vision loss in the U.S. Usually asymptomatic until advanced visual field loss has occurred; less than 50% of those...
متن کاملAssociation between p53 Codon 72 (Arg72Pro) Polymorphism and Primary Open-Angle Glaucoma in Iranian Patients
Background: Glaucomatous neuropathy is a type of cell death due to apoptosis. The p53 gene is one of the regulatory genes of apoptosis. Recently, the association between the p53 gene encoding for proline at codon 72 and primary open-angle glaucoma (POAG) has been studied in some ethnic groups. This study is the first association analysis of POAG and p53 codon 72 polymorphism in Iranian patients...
متن کاملScreening of CYP1B1 Arg368His as predominant mutation in North Indian primary open angle glaucoma and juvenile onset glaucoma patients
In India, mutations in Cytochrome P450 (CYP1B1) are a predominant cause of not only primary congenital glaucoma (PCG) but also involved in primary open angle glaucoma (POAG) and juvenile onset glaucoma (JOAG). After ethical clearance, 100 POAG patients, 30 primary angle closure glaucoma (PACG) patients and 130 ethnically matched controls were recruited in this study. Genomic DNA was is...

متن کاملAqueous Humor Levels of Soluble Fas and Fas-ligand in Patients with Primary Open Angle and Pseudoex-foliation Glaucoma
Background: Glaucoma is one of the most common causes of blindness and is usually associated with elevated intraocular pressure. In patients with primary open angle glau-coma the number of trabecular meshwork cells is decreased. Death of the trabecular meshwork cells may be a result of apoptosis. Objective: To investigate the aqueous humor levels of soluble Fas (sFas) and Fas-Ligand (sFasL) in ...
