چکیده

Purpose Sex hormones may be associated with primary open-angle glaucoma (POAG), although the mechanisms are unclear. We previously observed that gene variants involved with estrogen metabolism were collectively associated with POAG in women but not men; here we assessed gene variants related to testosterone metabolism collectively and POAG risk. Methods We used two datasets: one from the United States (3853 cases and 33,480 controls) and another from Australia (1155 cases and 1992 controls). Both datasets contained densely called genotypes imputed to the 1000 Genomes reference panel. We used pathway- and gene-based approaches with Pathway Analysis by Randomization Incorporating Structure (PARIS) software to assess the overall association between a panel of single nucleotide polymorphisms (SNPs) in testosterone metabolism genes and POAG. In sex-stratified analyses, we evaluated POAG overall and POAG subtypes defined by maximum IOP (high-tension [HTG] or normal tension glaucoma [NTG]). Results In the US dataset, the SNP panel was not associated with POAG (permuted P = 0.77), although there was an association in the Australian sample (permuted P = 0.018). In both datasets, the SNP panel was associated with POAG in men (permuted P ≤ 0.033) and not women (permuted P ≥ 0.42), but in gene-based analyses, there was no consistency on the main genes responsible for these findings. In both datasets, the testosterone pathway association with HTG was significant (permuted P ≤ 0.011), but again, gene-based analyses showed no consistent driver gene associations. Conclusions Collectively, testosterone metabolism pathway SNPs were consistently associated with the high-tension subtype of POAG in two datasets.

Glutathione s-transferase M1 and T1 genetic polymorphisms in Iranian patients with glaucoma

Objective(s):Glaucoma is the second leading cause of blindness and it is related to oxidative stress based on numerous studies. Glutathione S-transferases (GSTs) are members of multigenic family, which have important role in cells as an antioxidant. In the present study, we examined the polymorphism of GSTT1 and GSTM1 deletion genotypes (T0M1, T1M0, and T0M0) in 100 Glaucoma patients (41with pr...

Aqueous 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 ...

Estrogen pathway polymorphisms in relation to primary open angle glaucoma: An analysis accounting for gender from the United States

PURPOSE Circulating estrogen levels are relevant in glaucoma phenotypic traits. We assessed the association between an estrogen metabolism single nucleotide polymorphism (SNP) panel in relation to primary open angle glaucoma (POAG), accounting for gender. METHODS We included 3,108 POAG cases and 3,430 controls of both genders from the Glaucoma Genes and Environment (GLAUGEN) study and the Nat...
