Changes in Expression of Aquaporin-4 and Aquaporin-9 in Optic Nerve after Crushing in Rats

The purpose of this study was to determine the temporal and spatial changes in the expression of AQP4 and AQP9 in the optic nerve after it is crushed. The left optic nerves of rats were either crushed (crushed group) or sham operated (sham group), and they were excised before, and at 1, 2, 4, 7, and 14 days later. Four optic nerves were pooled for each time point in both groups. The expression ...

Changes in ocular aquaporin expression following optic nerve crush

PURPOSE Changes in the expression of water channels (aquaporins; AQP) have been reported in several diseases. However, such changes and mechanisms remain to be evaluated for retinal injury after optic nerve crush (ONC). This study was designed to analyze changes in the expression of AQP4 (water selective channel) and AQP9 (water and lactate channel) following ONC in the rat. METHODS Rat retin...

Reduced expression of aquaporin-9 in rat optic nerve head and retina following elevated intraocular pressure.

PURPOSE To investigate the effect of chronically elevated intraocular pressure (IOP) on the expression of water channel aquaporins (AQPs) 1, 4, and 9 in the optic nerve and retina in rats. METHODS Three episcleral veins were cauterized to elevate IOP in the left eyes of Sprague-Dawley rats. IOPs were monitored with a rebound tonometer. At 2 and 4 weeks after surgery, eyeballs with the attache...

Changes in retinal aquaporin-9 (AQP9) expression in glaucoma

The eye contains numerous water channel proteins and the roles of AQPs (aquaporins) in the retina are blurred, especially under disease conditions. The purpose of this study was to investigate the expression of AQP9 gene and proteins affected by elevated IOP (intraocular pressure) in a rat model of glaucoma induced by intravitreous injection of hypertonic saline into the episcleral veins. The g...

Changes in ocular aquaporin-4 (AQP4) expression following retinal injury

PURPOSE Changes in the expression of water channels or aquaporins (AQP) have been reported in several diseases. However, such changes and mechanisms remain to be evaluated for retinal injury. This study was designed to analyze changes in the expression of AQP4 following elevation of intraocular pressure (IOP) and after intravitreal endothelin-1 injection and the potential involvement of the ubi...
