Abstract |
The pathological mechanisms underlying increased outflow resistance at the trabecular meshwork (TM) that is responsible for elevating intraocular pressure (IOP) have not been fully delineated. Recent studies have shown that progressive accumulation of misfolded proteins and induction of endoplasmic reticulum (ER) stress is associated with the pathophysiology of glaucomatous TM damage and IOP elevation. We have shown that known causes of human glaucoma, including expression of mutant myocilin or dexamethasone treatment induce abnormal protein accumulation and ER stress in the TM in vitro and in vivo models. To cope up with abnormal protein accumulation, TM cells activate a cytoprotective pathway of unfolded protein response (UPR). However, chronic ER stress can lead to TM dysfunction and IOP elevation. Using cell culture, mouse models, and human postmortem tissues as well as genetic and pharmacological manipulations, we have analyzed ER stress and UPR mediators in the glaucomatous TM damage and IOP elevation. In this chapter, we have described a detailed protocol for the analysis of protein misfolding and ER stress in TM cells and tissues and its association with glaucomatous TM damage and IOP elevation. |
