Apoptosis in the trabecular meshwork of glaucomatous patients
نویسندگان
چکیده
We established and validated an in toto method to perform TdT-mediated dUTP nick end labeling to study apoptosis in human trabecular meshwork tissue obtained during trabeculectomy in glaucoma patients. In specimens from patients with primary open-angle glaucoma and primary angle-closure glaucoma, we detected a tendency for more apoptotic cells to accumulate in patients with primary open-angle glaucoma. The utility of this method to study apoptosis in the trabecular meshwork is discussed, as well as its application as a tool in biologic samples.

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 ...

PURPOSE To examine the differential staining of two potential stress-response markers, alpha B-crystallin and the trabecular meshwork inducible glucocorticoid response protein (TIGR), in meshwork from normal and glaucomatous human eyes. METHODS Trabecular meshwork from 35 eyes from 23 donors with either primary open-angle glaucoma, pseudoexfoliative glaucoma, or low-tension glaucoma, and from...
متن کاملRegulation of glucocorticoid responsiveness in glaucomatous trabecular meshwork cells by glucocorticoid receptor-beta.
PURPOSE Glucocorticoid administration can lead to increased intraocular pressure in greater than 90% of patients with primary open-angle glaucoma (POAG), compared with 30% to 40% of the general population. The molecular mechanisms for increased steroid responsiveness among patients with glaucoma are unknown. An alternative splicing variant of the human glucocorticoid receptor GRbeta has dominan...
متن کاملMitochondrial Damage in the Trabecular Meshwork Occurs Only in Primary Open-Angle Glaucoma and in Pseudoexfoliative Glaucoma
BACKGROUND Open-angle glaucoma appears to be induced by the malfunction of the trabecular meshwork cells due to injury induced by oxidative damage and mitochondrial impairment. Here, we report that, in fact, we have detected mitochondrial damage only in primary open-angle glaucoma and pseudo-exfoliation glaucoma, among several glaucoma types compared. METHODOLOGY/PRINCIPAL FINDINGS Mitochondr...
